Description

MULTISTAGE TEST RESULT INTERFACE DELIVERING TEST RESULTS FOR AN OPTICAL MULTIFIBER COMMUNICATION LINKBACKGROUNDTechnical Field

[0001] This disclosure pertains to apparatus and methods for delivering test results from testing optical multifiber communication links.Description of the Related Art

[0002] Optical fibers are often deployed in communication networks, such as telephone networks, cable systems, and computer communication networks (e.g., Internet) for high-speed data communication. To address increasing demand for bandwidth and communication throughput, optical communication links between endpoints in such networks include an increasing number of optical fibers. Multifiber communication cables allow for fast deployment of greater numbers of optical fibers. Multifiber communication cables are terminated by connectors, such as a ceramic ferrule or a bulkhead adapter, that enable multiple optical fibers to be collectively added, removed, or deployed within the communication network. When the connectors of a multifiber communication cable are coupled to respective ports of transmitting and receiving network equipment, the connectors align the optical fibers with respective optical communication components in the network equipment. High-density multifiber communication links that include 16, 24, or more optical fibers are emerging.

[0003] Optical fibers enable high-speed data transmission with relatively low loss. After installation of an optical communication link, it is important to test the optical communication link to confirm and / or certify that the optical fibers in the communication link are correctly aligned, configured, and able to successfully communicate data within expected parameters. One such parameter may be a measured amount of loss of optical power in a light signal transmitted over the optical fibers. Other parameters may be a measured length of each optical fiber under test and / or a polarity of the connection of the optical fibers in the optical communication link. Testing can determine whether there are faults in the optical communication link that may diminish or prevent successful communication of data in the installation. In some cases, measured parameters of the optical fibers in the optical communication link are compared with specified limits (e.g., criteria) of one or more standards. Such standards may be locally generated or may be third-party standards published by, for example, the International Electrotechnical Commission (IEC) or various other organizations that set objective requirements for optical communication links. Other organizations that publish standards include the Telecommunications Industry Association (TIA), Technical Standard Board (TSB), International Organization for Standardization (ISO), and Institute of Electrical and Electronic Engineers (IEEE).

[0004] In some cases, contamination of the end faces of optical fibers or defects in the optical fibers themselves may cause a loss of optical power in an optical signal communicated via the optical communication link. Such defects may block, diffuse, or misdirect the optical signal, thereby affecting the quality of the signal, e.g., by reducing the intensity of the signal or introducing artifacts into the signal while the signal is being transmitted. The optical power loss may exceed a specified limit, such as a threshold maximum power loss, of a predetermined standard. In other examples, the length of the fiber optic cable may exceed a specified maximum length and / or misconnection of the optical fibers in the optical communication link may result in an incorrect polarity, causing a failure of the optical communication link.

[0005] When displaying test results from testing that is conducted on a multifiber communication link, many displays are not large enough to simultaneously show all of the test results for all of the optical fibers in the optical communication link at a desired resolution, especially for high-density multifiber communication links including 16, 24, or more optical fibers. What is needed, at least in part, is an improved test result interface for delivering test results from testing a multifiber communication link, where the test result interface enables a user to see and understand overall test results with greater ease and efficiency, yet provides improved capabilities for the user to evaluate the test results of one or more individual optical fibers in the multifiber communication link.BRIEF SUMMARY

[0006] Embodiments and examples described herein provide improved apparatus and methods for delivering test results from testing conducted on optical multifiber communication links. Advantages obtained by the present disclosure are particularly apparent when delivering test results from testing high-density optical multifiber communication links comprised of, for example, 16, 24, or more optical fibers.

[0007] In at least one aspect, described herein is an apparatus that includes an optional display and a processor in communication with the display. The processor is configured, e.g., by circuitry or executable instructions, to receive test results of testing that was conducted on a plurality of optical fibers. The optical fibers may be bundled together or otherwise arranged in an optical multifiber communication link. The processor generates a multistage test result interface for delivering the test results.

[0008] In at least one aspect, in a first stage, the multistage test result interface provides, on the display, a summary interface that includes a summary test result but does not include individual test results for all of the plurality of optical fibers. The summary test result may be a measured parameter of an optical fiber among the plurality of optical fibers in the optical multifiber communication link. In some cases, the summary interface may include features such as a simplified graphical representation of the optical multifiber communication link and / or an indication whether the test results for the optical multifiber communication link meet or otherwise collectively satisfy specified limits (e.g., criteria) of a predefined standard. In a second stage, the multistage test result interface provides, on the display, a detailed interface thatincludes features such as a representation of two or more optical fibers in a subset of the plurality of optical fibers. The representation may be a graphical representation of two or more optical fibers in a subset of the plurality of optical fibers, e.g., as connected in the optical multifiber communication link. The subset of optical fibers, in this regard, includes less than all of the plurality of optical fibers. The representation of the two or more optical fibers in the subset includes test results, for example measured parameters, of the two or more optical fibers. The detailed interface may also include a map, e.g., a graphical map, identifying the two or more optical fibers that are shown. The detailed interface is adjustable as to which optical fibers of the plurality of optical fibers are represented, e.g., according to user input.

[0009] In another aspect, described herein is method of displaying test results for an optical multifiber communication link. The method includes receiving test results of testing conducted on a plurality of optical fibers in the optical multifiber communication link, and providing, on a display, a multistage test result interface. The multistage test result interface includes a first stage and a second stage. In at least one aspect, in the first stage, the multistage test result interface provides, on the display, a summary interface. The summary interface includes at least one test result of a measured parameter of an optical fiber among the plurality of optical fibers. In the second stage, the multistage test result interface provides, on the display, a detailed interface. The detailed interface shows a graphical representation of two or more optical fibers in a subset of the plurality of optical fibers. The graphical representation includes test results of measured parameters of the two or more optical fibers. According to a user input, the particular optical fibers that are represented and shown in the detailed interface is adjustable.

[0010] In another aspect, described herein is a method of generating a multistage test result interface for delivering test results. The method includes receiving test results of testing conducted on a plurality of optical fibers in an optical multifiber communication link, and generating, on a display, the multistage test result interface. Generating the multistage test result interface includes, in a first stage, providing a summary interface on the display. While the summary interface includes a summary test result, the summary interface does not include individual test results for all of the plurality of optical fibers.

[0011] Generating the multistage test result interface also includes, in a second stage, providing a detailed interface on the display. In at least one aspect, the detailed interface includes a representation of two or more optical fibers in a subset of the plurality of optical fibers. The representation includes test results for the two or more optical fibers in the subset. The subset includes less than all of the plurality of optical fibers.

[0012] In response to receipt of a triggering command, the multistage test result interface transitions from providing the summary interface on the display to providing the detailed interface on the display. In at least one aspect, the method further includes adjusting, according to a user input, which optical fibers of the plurality of optical fibers are in the subset and represented in the detailed interface.

[0013] These concepts and features, as well as other concepts and features, are exemplified by various embodiments and implementations of the present disclosure as described herein.BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0023] In any network arrangement, it is valuable to test a communication link such as an multifiber optical communication link to confirm and / or certify that the communication link is correctly configured and is able to successfully communicate data, e.g., within specified limits of a predetermined standard. This includes testing of high-density optical multifiber communication links that include 16, 24, or more optical fibers. After testing a communication link having a large number of optical fibers, it is important to show the test results on a display in a mannerthat is easy to read and interpret (z.e., not cluttered or confusing to a user), and which ultimately is useful to the user.

[0024] Disclosed herein are apparatus and methods for delivering test results for an optical multifiber communication link in a multistage test result interface. The optical multifiber communication link includes a plurality of optical fibers that are connected between communication endpoints, e.g., by coupling connectors of a multifiber communication cable between an optical transmitter and optical receiver. As will be described herein, in a first stage the multistage test result interface provides a summary interface on a display. In at least one example, the summary interface includes a graphical representation of the optical multifiber communication link as a collective link, for example without graphically representing individual optical fibers in the optical multifiber communication link. The summary interface includes at least one test result of a measured parameter obtained from testing the optical fibers in the optical multifiber communication link. In at least one example, the summary interface includes a test result of a measured parameter obtained from an optical fiber among the optical fibers in the optical multifiber communication link. The summary interface may, for example, be configured to display the test result of a “worst case” optical fiber, in relation to a measured parameter of the optical fibers that were tested.

[0025] In a second stage that follows the first stage, the multistage test result interface provides a detailed interface on the display. In at least one example, the detailed interface shows a graphical representation of a subset of the plurality of optical fibers in the optical multifiber communication link, e.g., a graphical representation of two or more individual optical fibers in the link. The graphical representation includes test results of measured parameters of the two or more optical fibers in the subset. In some cases, a user can adjust which optical fibers of the plurality of optical fibers are represented in the detailed interface. In this manner, the user is able to view test results for a subset (z.e., less than all) of the optical fibers in the optical multifiber communication link and, as desired, adjust or modify the detailed interface to see different subsets of the optical fibers. While all of the test results of the plurality of optical fibers are available for viewing in the detailed interface in various subsets, the user can selectively view the test results to focus the detailed interface on a particular subset or subsets of the optical fibers that are of interest. For example, the user may wish to focus on optical fiber(s) that, as tested, failed to satisfy specified limits, e.g., of a predetermined standard. The user can easily navigate among the test results of the individual optical fibers and focus on relevant test results of a subset of the optical fibers, without having to simultaneously view all of the test results for all of the optical fibers in the optical multifiber communication link.

[0026] In another example, the multistage test result interface includes a first stage in which a summary interface is provided on the display. The summary interface includes a summary test result but does not include all of the measured values for all of the optical fibers in the plurality of optical fibers. The multistage test result interface further includes a second stage is which a detailed interface is provided on the display. The detailed interface includes graphical representations of measured values for some or all of the plurality of optical fibers, a numericrepresentation of a measured value for each of one or more optical fibers in a subset of the plurality of optical fibers, and a focus indicator indicating the one or more optical fibers in the subset. The graphical representations may, for example, be arranged in a chart that displays test results of measured parameters of the optical fibers. The subset includes less than all of the plurality of optical fibers. In response to a triggering command, the multistage test result interface transitions from the summary interface to the detailed interface. Advantageously, in expedient embodiments, the one or more optical fibers in the subset indicated by the focus indicator is adjustable.

[0027] The user can selectively direct the focus indicator to one or more particular optical fibers in the detailed interface to view the numeric measured values for the particular optical fiber(s). The user can thus focus aspects of the detailed interface on one or more optical fibers of interest. For example, the user may wish to focus on optical fiber(s) that, as tested, failed to satisfy a specified limit (threshold or other criteria), e.g., of a predetermined standard. The user can easily navigate among the test results of the individual optical fibers and focus on relevant test results for particular optical fibers without having to simultaneously view all of the numerical values for all of the parameters measured for all of the optical fibers in the optical multifiber communication link.

[0028] As will be described herein, a multistage test result interface according to aspects of this disclosure thus includes (1) a summary interface displayed in a first stage, and (2) a detailed interface displayed in a second stage. The summary interface provides limited test results, e.g., for a single fiber optic cable in the optical multifiber communication link that was tested, while the detailed interface provides additional information directed to multiple optical fibers, in some cases less than all of the optical fibers, in the optical multifiber communication link. In this manner, a user is presented with a display of test results that is easier to read, less cluttered, and more efficient to interpret, which is more useful to the user. If the user desires to see more detailed information, the user can cause the multistage test result interface to progress from the summary interface to displaying the detailed interface.

[0029] In some cases, the summary interface is displayed by the multistage test result interface until a command is received, and in response to receipt of the command, the multistage test result interface provides the detailed interface. If, for example, all of the test results for the optical fibers in the optical multifiber communication link are satisfactory, that is, the test results for all of the fibers satisfy specified limits of a standard and result in a “passing grade,” the user can choose to not view more detailed information in the detailed interface. The user can immediately proceed to view test results from different testing, perhaps of a different communication link. On the other hand, if for example some of the test results fail to satisfy the specified limits of a standard, the test results for the communication link may be given a “failing grade,” and the user can choose to view more detailed information in the detailed interface to better understand the failed test results.

[0030] In some cases, the detailed interface displayed by the multistage test result interface includes at least two sections, or regions, on the display. The first section includes agraphical representation of two or more optical fibers (z.e., a subset of optical fibers that is less than all of the optical fibers) in the optical multifiber communication link. The second section includes a graphical map depicting an array of icons, with each icon corresponding a respective one of the optical fibers in the optical multifiber communication link. The second section also includes a selection window that is shown at a position with respect to the array of icons identifying those icons that correspond to the two or more optical fibers shown in the first section. By way of user input, the user can adjust which optical fibers are graphically represented in the first section, which correspondingly modifies the position of the selection window in the second section. Similarly, by way of user input, the user can modify the position of the selection window in the second section, which correspondingly adjusts which optical fibers are graphically represented in the first section. As a result, the display of individual optical fibers in the first section is directed according to the user’s interests, and such optical fibers shown in the first section are consistently identified in the second section by the corresponding icons within the selection window. The user can easily navigate and view test results for desired subset of the optical fibers in the communication link, for example to focus on the optical fibers whose test results failed to satisfy specified limits of a standard.

[0031] In some cases, the user can provide input in the form of a swipe gesture that adjusts which optical fibers are graphically represented in the detailed interface. In response to a swipe gesture, the first section of the detailed interface can be modified to show a graphical representation of a different subset of optical fibers in the optical multifiber communication link, and the selection window is correspondingly repositioned with respect to the array of icons in the second section of the detailed interface to consistently identify the icons that correspond to the optical fibers shown in the first section. Swipe gestures are generally intuitive to users, and by way of a swipe gesture, a user can easily navigate and adjust which optical fibers and their corresponding test results are displayed in the detailed interface.

[0032] In some cases, input from the user can include a zoom gesture (e.g. , by a tap, pinch, or expanding gesture) that enlarges or reduces the size of the graphical representation of the optical fibers that are shown in the first section of the detailed interface. For example, in response to a zoom gesture, the graphical representation of optical fibers in the first section can be enlarged or reduced, depending on whether the gesture is interpreted as a zoom in or zoom out gesture. Correspondingly, the size of the selection window in the second section of the detailed interface is enlarged or reduced. As with swipe gestures, zoom gestures are generally intuitive to users. By way of a zoom gesture, a user can easily enlarge the graphical representation in the first section, helping the user better view desired optical fibers and corresponding test results. The user can also reduce the size of the graphical representations in the first section, helping the user to see a greater number of optical fibers and corresponding test results in the first section.

[0033] In some cases, the detailed interface displayed by the multistage test result interface selectively illustrates test results for a particular parameter of a plurality of parameters of the optical fibers that were tested. For example, the detailed interface may selectively illustrate one of measured optical loss or fiber length or polarity of the optical fibers in the multifibercommunication link under test. Input from the user may include a swipe or scrolling navigation in the detailed interface to direct a focus indicator on one or more particular optical fibers. The measured parameters of the optical fiber or fibers in the focus indicator are specifically displayed. When the focus indicator is moved to encompass other optical fiber(s), the measured parameters shown in the detailed interface are adjusted to report test results for only the optical fiber(s) in the focus indicator. The focus indicator may also be enlarged or reduced in size to include or exclude optical fibers in the subset.

[0034] Turning to the drawings, Figure l is a block diagram illustrating an optical fiber testing tool 100 that includes an apparatus 102 in accordance with at least one example of the present disclosure. The apparatus 102 is configured to deliver test results from testing conducted on multiple optical fibers, e.g., in an optical multifiber communication link 116. The optical fiber testing tool 100 includes an optical fiber connection interface 104 having a port 112. In Figure 1, the port 112 is shown coupled to a connector 114 of the optical multifiber communication link 116. At an opposite end of the optical multifiber communication link 116, the optical fibers are shown coupled to a network device 120 which may be, for example, a transceiver or other communication system or computing hardware supporting optical communication. More specifically, in Figure 1, a connector 118 of the optical multifiber communication link 116 is shown coupled to a port 122 of an optical fiber connection interface 124 of the network device 120.

[0035] The apparatus 102 includes an optional display 106, a processor 108, and a memory 110. The processor 108 is shown in communication with the display 106 and the memory 110. The memory 110 is a non-transitory computer-readable storage medium that, in many cases, has stored thereon executable instructions that, when executed by the processor, configure and cause the processor to perform tasks as described herein, including tasks to receive test results of testing conducted on a plurality of optical fibers in the optical multifiber communication link 116 and provide a multistage test result interface on the display 106, as described herein. The processor 108 may include one or more processing devices (microprocessor, programmable controllers, application specific integrated circuits, etc.) that are configured individually and / or collectively, whether in software programming or hardware, to perform various processing tasks described herein.

[0036] In some implementations, the apparatus 102 may be a multipurpose device, such as a smart phone, a tablet computer, a laptop, or a server computer that is communicatively coupled to the optical fiber testing tool 100. In some implementations, the apparatus 102 may be integrated into the optical fiber testing tool 100.

[0037] The connection port 112 of the optical fiber testing tool 100 may be configured to receive multiple different types of connectors 114 coupled to different optical multifiber communication links 116 having fiber optic cables to be tested. In some cases, the connection port 112 may be integrated in the optical fiber testing tool 100. Each type of connector 114 may arrange the end faces of the optical fibers in the communication link 116 in different arrays to achieve different polarities. For example, one type of connector 114 has sixteen optical fiberscoupled thereto which are arranged in a single row. This type of connector 114 is considered as presenting a 1 x 16 array of optical fiber end faces to the optical fiber testing tool 100.

[0038] Another type of connector 114 has twenty -four optical fibers coupled thereto which are arranged in two rows. This type of connector 114 is considered as presenting a 2* 12 array of optical fiber end faces to the optical fiber testing tool 100.

[0039] Still another type of connector 114 has thirty -two optical fibers coupled thereto which are arranged in two rows. This type of connector 114 is considered as presenting a 2* 16 array of optical fiber end faces to the optical fiber testing tool 100. It should be appreciated that the connector 114 may arrange the end faces of the optical fibers in the optical multifiber communication link 116 in any desirable array having any number of rows, columns, or other geometric arrangements. It should also be appreciated that the optical fiber testing tool 100 may include multiple different ports 112 to accommodate multiple different connectors 114.

[0040] In some cases, the optical fiber testing tool 100 may be configured to detect the type of connector 114 that is received by the connection port 112 and identify therefrom the particular array of end faces presented by the connector 114 to the optical fiber testing tool 100. For example, each type of the connector 114 may have a different perimeter or profile that is mechanically or electronically detectable by the optical fiber testing tool 100, e.g., using for example one or more electronic switches or visual identification devices located in or around the connection port 112 of the fiber connection interface 104. Alternatively, or in addition, the connector 114 may include circuitry that communicates, by wired or wireless communication, a data code to the connection port 112 or other portion of the optical fiber testing tool 100 that identifies the particular type of connector 114, and possibly the type of polarity, of the optical multifiber communication link 116 being coupled to the connection port 112.

[0041] In various implementations, the multistage test result interface of the present disclosure includes a first stage which provides, on the display 106, a summary interface, e.g., as illustrated in Figures 3 A and 4A described below. In a second stage, the multistage test result interface provides, on the display 106, a detailed interface, e.g., as illustrated in Figures 3B and 4B.

[0042] Advantages of providing test results in a multistage test result interface as described herein are appreciated in contrast with conventional test result interfaces. Figure 2 illustrates one example of a conventional test result interface 200 showing test results from testing a pair of optical fibers 202. The optical fibers 202 are coupled between a main device 204 and a remote device 206.

[0043] The conventional test result interface 200 displays representations and corresponding test results 208, 210 for all of the optical fibers 202 being tested. The test results 208, 210 in this example include a detected optical loss and a cable length of each of the optical fibers tested. The optical fibers 202 shown are individual optical fibers. Additionally, in this example, the conventional test result interface 200 displays information 212 such as the type of optical fiber under test and the test limit, or standard, by which the test results 208, 210 areevaluated. In this case, as illustrated, the test results 208, 210 are within the test limits of the indicated standard, and therefore the optical fibers 202 are given a passing grade 214. Notably, the conventional test result interface 200 does not include a summary interface as described herein, nor does it include a detailed interface as described herein.

[0044] While the conventional test result interface 200 may be useful when testing communication links having a limited number of optical fibers, the outcome is different when testing is performed on a higher number of optical fibers, such as on high-density optical multifiber communication links having 16, 24, or more optical fibers. It is easy to appreciate that the conventional test result interface 200 becomes overcrowded and difficult to read in such circumstances, given the number of individual optical fibers and corresponding test results that are shown in the interface 200.

[0045] By way of contrast, Figures 3 A and 3B illustrate a multistage test result interface provided by an apparatus 102 in accordance with the present disclosure. Different from the conventional test result interface 200 in Figure 2, the multistage test result interface in Figures 3A and 3B first provides, on the display 106, a summary interface 300. In this example, the summary interface 300 depicts an optical multifiber communication link 302 coupled between a main optical device 304 and a remote optical device 306 that transmit and receive optical signals between them. In some cases, the optical fiber testing tool 100 may be the main optical device 304, and in other cases, the optical fiber testing tool 100 may be the remote optical device 306.

[0046] The optical multifiber communication link 302 is indicated by a graphical line representing the overall communication link, rather than multiple lines representing individual optical fibers that comprise the optical multifiber communication link 302. In at least some implementations, the graphical depiction of the optical multifiber communication link 302 includes an indication 310 of the number of optical fibers in the optical communication link. In this example as illustrated, the indication 310 informs the user that the optical multifiber communication link 302 includes sixteen optical fibers.

[0047] The summary interface 300 is configured to include limited information as a test result overview, without displaying representations of all of the individual optical fibers tested and / or their corresponding individual test results. In this example, the summary interface 300 includes a summary test result 308, e.g., a measured parameter or pass / fail status, of an optical fiber among the plurality of the optical fibers that were tested. The summary interface 300 does not include representations of all of the individual optical fibers that were tested, nor does it include corresponding individual test results of all of the individual optical fibers that were tested, thus avoiding a cluttered test result interface that is difficult to read and evaluate. The measured parameter (or parameters in some cases) shown in the summary test result 308 may be, for example, optical loss, fiber length, and / or communication link polarity. In some implementations, the summary interface 300 provides the summary test result 308 for only one optical fiber among the plurality of optical fibers in the optical multifiber communication link 302. In some implementations, the test result shown may be for an optical fiber that presents the “worst” result in relation to a measured parameter (such as optical loss) of all the optical fibersthat were tested. By presenting a limited amount of test results, e.g., a test result for a single “worst case” optical fiber, the summary interface 300 allows the user to quickly evaluate the testing performed and determine if viewing more detailed information is helpful or necessary.

[0048] If the test results for all of the optical fibers in the optical multifiber communication link 302 are satisfactory, that is for example if the test results fall within or otherwise satisfy one or more specified limits of a predetermined standard, the summary interface 300 may display a “passing grade” 312. If, on the other hand, one or more of the test results fail to fall within or satisfy the specified limits of the predetermined standard, the test results for the m optical multifiber communication link 302 may be given a “failing grade,” e.g., as illustrated in Figure 4A, discussed below. In this manner, the summary interface 300 includes an indication of whether the test results for the optical multifiber communication link collectively satisfy specified limits of a predetermined standard. In any case, the user can choose to view more detailed information in a detailed interface 314, as shown in Figure 3B, to evaluate and better understand the test results of the individual optical fibers in the optical multifiber communication link 302.

[0049] In some cases, the processor 108 provides the summary interface 300 on the display 106 until a triggering command is received by the processor 108, and in response to receipt of the triggering command, the processor 108 provides, on the display 106, the detailed interface 314. User input to the summary interface 300, for example a tap or swipe on the summary test result 308, may cause the multistage test results interface to transition 313 to the second stage in which the display shows the detailed interface 314. Thus, in some cases, the summary interface 300 includes a summary section containing at least one summary test result 308, and the processor 108 receives the triggering command to transition to the detailed interface 314 as a result of user selection of the summary test result 308.

[0050] Generally, though not required, when the detailed interface 314 is displayed, the detailed interface 314 replaces the summary interface 300. The detailed interface 314 shows a graphical representation of two or more individual optical fibers 316 in a subset of the plurality of optical fibers in the optical multifiber communication link 302. The two or more individual optical fibers 316 in the subset are less than all of the optical fibers that were tested. The graphical representation of the two or more optical fibers 316 is shown in a first section, or region, of the display. The graphical representation may be a graphical wiremap showing connections of the two or more optical fibers in the optical multifiber communication link 302.

[0051] In the example shown in Figure 3B, a graphical representation of four optical fibers 316 is shown in an upper or central section of the display. The four optical fibers 316 shown are a subset of the sixteen optical fibers in the optical multifiber communication link 302. The graphical representation of the individual optical fibers in the subset shown in the first section includes test results of measured parameters of the optical fibers.

[0052] The subset of four optical fibers 316 shown in Figure 3B includes, for example, the seventh, eighth, ninth, and tenth optical fiber of the sixteen optical fibers in the optical multifiber communication link 302. The four optical fibers 316 are coupled to the main opticaldevice 304 at respective end points 318a, 320a, 322a, 324a, and to the remote optical device 306 at respective end points 318b, 320b, 322b, 324b. The graphical representation of the four optical fibers may be a wiremap that indicates a correct or incorrect coupling of the optical fibers depending on an expected polarity of the optical multifiber communication link 302. The graphical wiremap shows the connections of the optical fibers 316 and a determination of whether the optical fibers are properly connected according to the expected polarity of optical fibers in the optical multifiber communication link 302.

[0053] In this example, diagonal hashmarks (which may represent a color such as green, or other visual indicator) indicate a “correct” connection of the four optical fibers shown. Each of the four depicted optical fibers 316 may also include respective test results 318c, 320c, 322c, 324c, such as a measured optical loss, with respect to each optical fiber.

[0054] By way of the detailed interface 314, the apparatus 102 provides, on the display 106, test results for some (e.g., two or more) but not all of the optical fibers in the optical multifiber communication link 302. The subset of optical fibers 316 that are graphically represented in the first section of the detailed interface 314 may include more or less than the four optical fibers shown. As will be described further below, the number of the optical fibers and which of the optical fibers are shown in the first section of the detailed interface 314 is adjustable, e.g., according to a user input received by the processor 108 of the apparatus 102.

[0055] To aid in identifying the particular optical fibers that are represented at a given time in the first section of the detailed interface 314, the graphical representations shown may include or otherwise be annotated to include numerals within or adjacent to the end points. In the example shown in Figure 3B, numerals “7”, “8”, “9”, and “10” are depicted in the four end points at both ends of the four optical fibers 316, indicating the seventh through tenth optical fibers in the plurality of optical fibers being inspected. However, such numerals are not required.

[0056] The detailed interface 314 further includes a second section, or region, of the display that shows a graphical map 328 depicting an array of icons corresponding to the optical fibers of the optical multifiber communication link 302 that were tested. In Figure 3B, the second section is shown in the lower part of the display, beneath the first section, though in other implementations, the second section could be shown above or to the side of the first section. In this example, the graphical map 328 includes sixteen circular icons that respectively correspond the sixteen optical fibers in the optical multifiber communication link 302. In this example, the processor 108 of the apparatus 102 has detected the type of connector 114 connected to the optical fiber connection interface 104 and identified that the connector 114 is coupled to an optical cable having sixteen optical fibers arranged in a single row. Accordingly, the sixteen circular icons are shown in the graphical map 328 in a single row. In this manner, the processor 108 may automatically generate the graphical map 328 based on the array of the optical fibers identified by detection of the type of a connector coupled to the connection port. Furthermore, in this implementation, the graphical map 328 depicts icons representing all of the optical fibers coupled to the connector 114, though in other implementations, e.g., with a larger number ofoptical fibers arranged in a single row, the graphical map 328 may be scrollable and depict only a portion of the icons at a given time.

[0057] Also depicted in the second section of the detailed interface 314 is a selection window 330. The selection window 330 is positioned with respect to the graphical map 328 to identify the icon or icons in the graphical map 328 that correspond to the optical fibers 316 that are shown in the first section of the detailed interface 314 at the given time. In this example, where the first section is shown displaying optical fibers “7” through “10”, the selection window 330 encompasses the seventh through tenth icons in the graphical map 328, and thus identifies the seventh through tenth optical fibers of the optical multifiber communication link 302. In various implementations, the selection window 330 may include a bordered perimeter as shown in Figure 3B, and the icons corresponding to the optical fibers 316 are depicted within the bordered perimeter. In some cases, the icons within the bordered perimeter of the selection window 330 may appear different than the icons outside the bordered perimeter, e.g., by using a different line thickness, transparency level, color, pattern, or shade. As will be discussed in more detail below, the selection window 330 may traverse across the graphical map 328 and encompass different icons depending on which optical fibers 316 are currently shown in the first section of the detailed interface 314.

[0058] Figures 4A and 4B illustrate a multistage test result interface provided by an apparatus 102 according to the present disclosure, including a summary interface 400 and a detailed interface 414, wherein the test result interface in this example indicates a failing grade 412. In this example, the summary interface 400 depicts an optical multifiber communication link 402 coupled between a main optical device 404 and a remote optical device 406. As with the optical multifiber communication link 302 shown in Figure 3A, the optical multifiber communication link 402 is represented by a single graphical line representing the overall communication link. The graphical depiction of the optical communication link 402 includes an indication 410 informing the user that the optical multifiber communication link 402 includes sixteen optical fibers.

[0059] As with the summary interface 300 in Figure 3 A, the summary interface 400 in Figure 4A includes limited information, without displaying graphical representations of all of the individual optical fibers that were tested and their corresponding test results. In this example, the summary interface 400 includes a test result 408 of one or more measured parameters (e.g., optical loss, fiber length, and / or link polarity) of an optical fiber among the plurality of the optical fibers that were tested.

[0060] In some implementations, the summary interface 400 provides the test result 408 for only one optical fiber of the plurality of optical fibers in the optical communication link 402. By presenting a limited amount of test results, e.g., a test result for a single “worst case” optical fiber, the summary interface 400 allows the user to quickly evaluate the testing performed and determine if viewing more detailed information would be helpful. In cases where one or more of the test results fail to fall within the specified limits of the standard, the test results for the communication link 402 may be given a “failing grade,” e.g., as illustrated at 412. In any case,the user can choose to transition from the summary interface 400 to a detailed interface 414, to view more detailed information as shown in Figure 4B.

[0061] A tap or swipe on the test results 408, or other user input to the summary interface 400, causes the multistage test results interface to transition 313 to the second stage in which the detailed interface 414 is shown. As with the detailed interface 314 in Figure 3B, the detailed interface 414 in Figure 4B shows a graphical representation of four individual optical fibers 416 in a subset of the plurality of optical fibers in the optical communication link 402. The individual optical fibers 416 are graphically represented in a first section, or region, of the display, e.g., an upper or central region of the display. The four optical fibers shown are a subset of the sixteen optical fibers in the optical communication link 402. As a default, the multistage test results interface may automatically initially select to show optical fibers 416 that include the optical fiber(s) representing the “worst case” among the test results of the optical fibers in the optical communication link 402, e.g., as indicated by the test result 408 shown in the summary interface 400.

[0062] The subset of four optical fibers 416 shown in Figure 4B includes the seventh, eighth, ninth, and tenth optical fiber of the sixteen optical fibers in the communication link 402, coupled between the main optical device 404 at respective end points 418a, 420a, 422a, 424a, and the remote optical device 406 at respective end points 418b, 420b, 422b, 424b. Depending on the expected polarity of the communication link 402, the graphical representation of the four optical fibers may be a wiremap indicating an incorrect coupling of the optical fibers. In this example, vertical hashmarks (which may represent a color such as red, or other visual indicator) indicate an “incorrect” or faulty connection of the seventh and eighth optical fibers. The seventh optical fiber is connected between the seventh endpoint 418a and the eighth endpoint 420b, while the eighth optical fiber is connected between the eighth endpoint 420a and the seventh endpoint 418b. Each of the four depicted optical fibers 316 include respective test results 418c, 420c, 422c, 424c, such as measured optical loss, with respect to optical fiber tested.

[0063] While the seventh and eighth optical fibers are indicated by vertical hashmarks as being incorrectly connected and thus failing to support the expected polarity of the communication link 402, the tenth optical fiber is also indicated by vertical hashmarks as failing to meet expectations. In this case, the tenth optical fiber is properly connected between the main and remote endpoints 424a, 424b, but the tenth optical fiber has a test result 424c reporting an optical loss that exceeds an optical loss test limit of the standard being applied. Thus, the seventh, eighth, and tenth optical fiber in this example contribute to the “failing” grade 412.

[0064] Similar to the detailed interface 313, the detailed interface 414 has a second section, or region, that includes a graphical map 428. The graphical map 428 depicts a 1 x 16 array of icons representing the sixteen optical fibers of the communication link 402. A selection window 430 is positioned with respect to the graphical map 428 to identify the icons in the graphical map 328 that correspond to the seventh to tenth optical fibers presently shown in the first section of the detailed interface 414. In particular, the selection window 430 includes a bordered perimeter that encompasses the seventh through tenth icons in the graphical map 428.The selection window 430 may traverse across the graphical map 428 and encompass different icons depending on which optical fibers 416 are currently shown in the first section of the detailed interface 414.

[0065] Figures 5A and 5B illustrate a feature of the detailed interface 314, 414 of the present disclosure, in which a user can adjust, based on a triggering signal such as a user input, which optical fibers are shown by the graphical representation in the detailed interface. In this example, the triggering signal (e.g., user input) is in the form of a swipe gesture 500.

[0066] In some implementations, the apparatus 102 may be configured such that at least a portion of the display 106 is a touchscreen. The user input detected by the touchscreen may be a swipe gesture generated by the user's finger or other implement interacting with the touchscreen and moving across the surface of the touchscreen. In response to receiving data from the touchscreen indicating a swipe gesture, the processor 108 may be programmed to modify the first section of the detailed interface 414 to show a graphical representation of a different subset of optical fibers, and also modify the position of the selection window 430 with respect to the graphical map 428 in the second section of the detailed interface 414 so that the selection window 430 consistently identifies the icons in the graphical map 428 that correspond to the particular optical fibers that are graphically represented in the first section of the detailed interface 414.

[0067] For example, the display 106 may detect a swipe gesture 500 indicating motion in a right direction, toward a right side of the display, as shown in the example in Figures 5A and 5B. In response to receiving data indicating the swipe gesture, the processor 108 may cause the first section of the detailed interface 414 to show a subset of the optical fibers that are to the right of the optical fibers that were previously shown. In Figure 5B, the subset of the optical fibers 502 represented in the first section is shown shifted toward the right, as evidenced by shifting from showing the seventh through tenth optical fibers to now showing the tenth through thirteenth optical fibers, as indicated by the numerals “10” through “13” at the end points 424a, 432a, 434a, 436a, and corresponding end points 424b, 432b, 434b, 436b.

[0068] Notably, in response to receiving data indicating the swipe gesture 500, the processor 108 also modifies the second section of the detailed interface 414 to show the selection window 430 repositioned in the right direction toward the right of the graphical map 428. In the graphical map 428 in Figure 5B, the selection window 430 identifies (e.g., by encompassing) the tenth through thirteenth icons in the array of icons corresponding to the sixteen optical fibers in the optical multifiber communication link 402. By repositioning the selection window 430 in the graphical map 428 (compare the position of the selection window 430 shown in Figure 5A with the position shown in Figure 5B), the user viewing the detailed interface 414 can readily identify which optical fibers of the optical multifiber communication link 402 are currently shown in the first section of the detailed interface 414. As may be readily appreciated, this is particularly useful in examples of the multistage test results display interface that do not include identifying numerals in the end points shown in the first section of the detailed interface 414. In such examples, the user can see which icons are within the selection window 430 and readilyrecognize which optical fibers are currently graphically represented in the first section of the detailed interface 414.

[0069] Similar processing is applied when the user input is a swipe gesture 500 indicating motion in a left direction, toward a left side of the display 106. In response, the processor 108 causes the first section of the detailed interface 414 to show a subset of the optical fibers shifted toward the left. Correspondingly, the processor 108 also causes the second section of the detailed interface 414 to reposition the selection window 430 in the left direction toward the left of the graphical map 428. For example (though not illustrated), the selection window 430 may shift to encompasses the fifth through ninth icon in the graphical map 428, indicating that optical fibers “5” through “9” are shown in the first section of the detailed interface 414.

[0070] Figures 6A and 6B illustrate another feature of the detailed interface 314, 414 of the present disclosure, in which a user can adjust a size of the graphical representation of the subset of optical fibers shown in the first section of the detailed interface, based on a triggering signal such as user input in the form of a zoom gesture.

[0071] In implementations in which the display 106 is a touchscreen, the display 106 may detect a zoom gesture 600 resulting from a user interaction with the display (e.g., a touch of the display) or a portion thereof. Different contexts of the display may produce different interpretation of a tap gesture. For instance, a tap gesture on the summary interface 400 shown Figure 4A may cause the transition 313 from the summary interface 400 to the detailed interface 414. A tap gesture on the detailed interface 414 may causes a zoom operation. Likewise, a pinch or expanding gesture 600 may cause a zoom operation.

[0072] In response to receiving data indicating a “zoom in” gesture, the processor 108 is programmed to modify the first section of the detailed interface 414, e.g., as shown in Figure 6A, to appear as illustrated by the first section shown in Figure 6B in which the graphical representations of particular optical fibers are shown enlarged. By enlarging the graphical representations, test results for certain optical fibers are more easily seen. In the example of Figure 6B, larger representations of the ninth and tenth optical fibers are shown. Similarly, a zoom gesture may be interpreted a “zoom out” gesture that modifies the first section of the detailed interface 414 to show a reduction in size of the graphical representations of the optical fibers shown, e.g., transitioning from the enlarged representations in Figure 6B to the reduced size representations in Figure 6A.

[0073] In response to receiving data indicating a “zoom in” or “zoom out” gesture, the processor 108 is also programmed to modify the size of the selection window 430 in the second section of the detailed interface 414. For example, in response to a “zoom in” gesture 600, the selection window 604 in Figure 6B is modified and now appears smaller in size as compared to the selection window 430 in Figure 6A. In the example of Figure 6B, the selection window 604 encompasses only the ninth and tenth icons in the graphical map 428, which corresponds with the graphical depictions of the ninth and tenth optical fibers in the first section of the detailed interface 414. In this manner, the selection windows 430, 604 consistently identify the icon oricons in the graphical map 428 that correspond to the optical fibers that are shown in the first section of the respective detailed interface 414.

[0074] A “zoom out” gesture causes the processor 108 to reduce the size of the optical fibers that are graphically represented in first section of the detailed interface. In response to the “zoom out” gesture, a different, larger subset of the optical fibers may be shown in the first section, reduced in size, based on specifics (e.g., extent) of the “zoom out” gesture. The processor 108 is further programmed to modify the size of the selection window 604 in the second section of the detailed interface 414 such that the selection window is shown larger in size, e.g., as illustrated by the selection window 430 in Figure 6A. Accordingly, the selection window in the second section of the display is able to consistently identify the icon or icons in the graphical map 428 that correspond to the optical fibers that are shown in the first section of the detailed interface 414.

[0075] In cases where the user input is a tap gesture, the tap gesture may indicate selection of a particular icon in the graphical map depicted in the second section of the detailed interface. In response to receiving data indicating such a tap gesture, the processor 108 may be configured to modify the first section of the detailed interface to show a graphical representation that includes at least the optical fiber corresponding to the particular icon. The processor 108 may also reposition the selection window with respect to the array of icons in the second section of the detailed interface such that the selection window consistently identifies the icons corresponding to the optical fibers that are graphically represented in the first section of the detailed interface.

[0076] Generally, it is anticipated that the processor 108 in the apparatus 102 responds to swipe or zoom gestures in real-time or approximate real-time. For example, as a user interacts with the display 106 and inputs a swipe gesture, while the user is swiping across the display, the graphical representations of the optical fibers 502, 602 shown in the first section and the corresponding selection window 430, 604 move to the right or left (in this example) in coordination with the swipe gesture. Such movement of the representations of the optical fibers 502, 602 and the selection window 430, 604 may be faster or slower depending on faster or slower speed of movement of the swipe gesture. In cases where the optical fibers of the optical multifiber communication link are arranged in the respective connectors in two or more rows (e.g., in a 2* 12 array of optical fiber end faces or a 2* 16 array of optical fiber end faces), a swipe gesture in two dimensions may cause the graphical representations of the optical fibers 502, 602 in the first section to shift in two dimensions, and correspondingly cause the selection window 430, 604 in the second section to shift in two dimensions (e.g., shifting between a first row and a second row in the graphical map (not illustrated). Similarly, a zoom-in or zoom-out gesture may produce enlarged or reduced size graphical representations of the optical fibers in the first section in more than one row, with a corresponding change in size of the selection window (larger or smaller, in two dimensions) in the second section.

[0077] In view of the foregoing description, it is appreciated that the present disclosure contemplates innovative methods of displaying test results for an optical multifibercommunication link. Figure 7 is a flow chart illustrating one example of a method 700 of generating a multistage test result interface for delivering test results according to the present disclosure. The method 700 includes receiving test results of testing conducted on a plurality of optical fibers in the optical multifiber communication link (block 702), and providing, on a display, a multistage test result interface. As described herein, the multistage test result interface includes a first stage providing (block 704), on the display, a summary interface, wherein the summary interface includes at least one test result of a measured parameter of an optical fiber among the plurality of optical fibers. The multistage test result interface subsequently provides a second stage providing (block 706), on the display, a detailed interface. The detailed interface shows a graphical representation of two or more optical fibers in a subset of the plurality of optical fibers. The graphical representation includes test results of measured parameters of the two or more optical fibers. The optical fibers that are represented in the detailed interface are adjustable (block 708), e.g., according to user input.

[0078] Such methods as described herein, for delivering test results for an optical multifiber communication link, may further include detecting a type of a connector having coupled thereto the plurality of optical fibers in the optical multifiber communication link and based on the type of the connector, identifying an array in which the optical fibers are coupled to the connector, and automatically generating, in the detailed interface, a graphical map depicting the array of the optical fibers.

[0079] Figures 8A and 8A illustrate another example of a multistage test result interface according to the present disclosure, wherein the test result interface includes a summary interface and a detailed interface and, in this example, indicates a passing grade.

[0080] Different from the conventional test result interface 200 in Figure 2, the multistage test result interface first provides, in a first stage, a summary interface 800 as shown in Figure 8A. In this example, the summary interface 800 depicts an optical multifiber communication link 802 coupled between a main optical device 804 and a remote optical device 806 that transmit and receive optical signals between them. Optical signals at different wavelengths (e.g., 1310 nm and 1550 nm) may be transmitted and received during the testing of the optical multifiber communication link 802. In some cases, the optical fiber testing tool 100 (Figure 1) may be the main optical device 804, and in other cases, the optical fiber testing tool 100 may be the remote optical device 806.

[0081] The optical multifiber communication link 802 graphically represents the communication link as a whole, rather than individual optical fibers that comprise the optical multifiber communication link 802. In at least some implementations, the graphical depiction of the optical multifiber communication link 802 includes an indication 810 of the number of optical fibers in the communication link. In this example as illustrated, the indication 810 informs the user that the optical multifiber communication link 802 includes twenty-four optical fibers.

[0082] The summary interface 800 is configured to include limited information as a test result overview. In this example, the summary interface 800 includes a summary test result 808,e.g., a measured parameter and / or a pass / fail status, of an optical fiber among the plurality of the optical fibers that were tested. The test results for the plurality of optical fibers include measured values of parameters measured in the testing. The summary interface 800 does not include representations of all of the individual optical fibers that were tested, nor does it include all of the measured values for all of the optical fibers that were tested, thus avoiding a cluttered test result interface that is difficult to read and evaluate. The measured parameter or parameters shown in the summary test result 808 may be, for example, optical loss, fiber length, and / or communication link polarity. In some implementations, the summary interface 800 provides the summary test result 808 for only one optical fiber among the plurality of optical fibers in the optical multifiber communication link 802. In some implementations, the test result shown may be for an optical fiber that presents the “worst” result in relation to a measured parameter (such as optical loss) of all the optical fibers that were tested. By presenting a limited amount of test results, e.g., a test result for a single “worst case” optical fiber, the summary interface 800 allows the user to quickly evaluate the testing performed and determine if viewing more detailed information is helpful or necessary.

[0083] If the test results for all of the optical fibers in the optical multifiber communication link 802 are satisfactory, that is for example if the test results fall within or otherwise satisfy one or more specified limits of a predetermined standard, the summary interface 800 displays a “passing grade” 812. If, on the other hand, one or more of the test results fail to fall within or satisfy the specified limits of the predetermined standard, the test results for the optical multifiber communication link 302 may be given a “failing grade,” e.g., as illustrated in Figure 9A, discussed below. In the example shown if Figures 8A-9B, the test limits are specified according to TIA-568-C Multimode standard. In this manner, the summary interface 800 includes an indication of whether the test results for the optical multifiber communication link 802 collectively satisfy specified limits of a predetermined standard. In any case, the user can choose to view more detailed information in a detailed interface 814 according to a second stage of the multistage test result interface, as shown in Figure 8B, to evaluate and better understand the test results of the individual optical fibers in the optical multifiber communication link 802.

[0084] In some cases, the processor 108 (Figure 1) provides the summary interface 800 on the display 106 until a triggering command is received by the processor 108, and in response to receipt of the triggering command, the processor 108 provides, on the display 106, the detailed interface 814. User input to the summary interface 800, for example a tap or swipe on the summary test result 808, may cause the multistage test results interface to transition 813 to the second stage in which the display shows the detailed interface 814. Thus, in some cases, the summary interface 800 includes a summary section containing at least one summary test result 808, and the processor 108 receives the triggering command to transition to the detailed interface 814 as a result of user selection of the summary test result 808.

[0085] Generally, though not required, when the detailed interface 814 is displayed, the detailed interface 814 replaces the summary interface 800. In the example shown, the detailedinterface 814 shows graphical representations 816 of measured values for the plurality of optical fibers, a numeric representation 824 of a measured value for each of one or more optical fibers in a subset of the plurality of optical fibers, the subset including less than all of the plurality of optical fibers, and a focus indicator 822 indicating the one or more optical fibers in the subset.

[0086] In the example shown, the graphical representations 816 of measured values for the plurality of optical fibers are arranged in a chart that graphically depicts the measured values of the twenty-four optical fibers in the optical multifiber communication link 802. In this case, the parameter shown is optical loss according to a scale 820 from 0 to 4 dB.

[0087] The focus indicator 822 indicates one or more optical fibers in a subset of the plurality of optical fibers, in this case optical fiber #08. In this example, diagonal hashmarks (which may represent a color such as green, or other visual indicator) indicate that the measured optical loss in each optical fiber does not exceed a maximum threshold optical loss (a specified limit represented in Figure 8B by a horizontal line on the chart), and therefore the optical fibers have an acceptable optical loss and collectively satisfy or “pass” the optical loss aspect of the test (which may be defined by a predetermined standard).

[0088] By way of the detailed interface 814, the apparatus 102 provides, on the display 106, a numeric representation 824 of a measured value for each of the one or more optical fibers in the subset indicated by the focus indicator 822. As illustrated, the subset includes less than all of the plurality of optical fibers in the optical multifiber communication link 802. The focus indicator 822, in this instance, is a rectangular box that graphically encompasses one or more optical fibers (here, optical fiber #08) in the subset. As will be described further below, the number of the optical fibers in the subset and which of the optical fibers are included in the subset is adjustable, e.g., according to a user input received by the processor 108 of the apparatus 102.

[0089] To aid in identifying the optical fibers that are represented in the detailed interface 814, the graphical representation may include or otherwise be annotated to include numerals 818. In the example shown in Figure 8B, numerals 1-24 are depicted, indicating optical fibers #01- #24. However, such numerals are not required.

[0090] As previously noted, in the detailed interface 814, the focus indicator 822 is positioned with respect to one or more of the graphical representations to indicate the one or more optical fibers in the subset for which numerical measured values 824 are shown. The processor 108 is configured to adjust, based on user input, which optical fibers of the plurality of optical fibers are in the subset and correspondingly modify the focus indicator 822 such that the focus indicator consistently indicates the optical fibers that are in the subset.

[0091] In some cases, the user input may be a swipe gesture and in response to receiving data indicating the swipe gesture, the processor 108 is configured to modify the positioning of the focus indicator 822 to indicate a different subset of optical fibers in the plurality of optical fibers.

[0092] In some cases, the user input may be a tap gesture on a directional icon 826, and in response to receiving data indicating the tap gesture, the processor 108 is configured to modifythe positioning of the focus indicator 822 to indicate a different subset of optical fibers according to the directional icon 826 tapped by the tap gesture. For example, if the user tapped on the leftdirection icon 826, the focus indicator 822 may move to the left and be repositioned to encompass the graphical representation for optical fiber #07. Similarly, if the user tapped on the right-direction icon 826, the focus indicator 822 may move to the right and be repositioned to encompass the graphical representation for optical fiber #09. In each case, when the focus indicator is modified (e.g., moved) to include a different optical fiber in the subset, the numerical values 824 are updated to reflect the measured numerical values of parameters measured for the optical fiber(s) that are currently in the subset.

[0093] In some cases, the user input may be a zoom gesture, and in response to receiving data indicating the zoom gesture, the processor 108 is configured to enlarge or reduce a size of the focus indicator 822 and correspondingly enlarge or reduce the number of optical fibers included in the subset. For example, if the focus indicator 822 were enlarged, it may encompass optical fibers #08 and #09. The numerical values 824 would be updated to reflect the measured numerical values of parameters measured for optical fibers #08 and #09.

[0094] In some cases, the user input is a tap gesture indicating a particular graphical representation of a measured value for a particular optical fiber, and in response to receiving data indicating the tap gesture, the processor 108 is configured to modify the positioning of the focus indicator 822 to include the particular optical fiber in the subset of optical fibers. For example, if the user tapped on optical fiber #12, the processor 108 would modify the positioning of the focus indicator 822 to encompass the graphical representation for optical fiber #12 and the numerical values 824 would be updated to reflect the measured numerical values of parameters measured for optical fiber #12.

[0095] As illustrated, the focus indicator 822 may include a bordered perimeter that encompasses the graphical representations of measured values of the one or more optical fibers (for example, in Figure 8B, optical fiber #08) in the subset. In some cases, as previously described, the apparatus is integrated into an optical fiber testing tool that includes a fiber connection interface couplable to a connector of the optical multifiber communication link. The fiber connection interface may include a connection port configured to receive multiple different types of connectors having optical fibers coupled thereto, each type of connector having the optical fibers arranged in an array. In such cases, the processor 108 may be configured to detect a type of connector coupled to the connection port, and based on the type of the connector, identify an array in which the optical fibers are coupled to the connector, and automatically determine and report a polarity of the optical fibers in the optical multifiber communication link.

[0096] The detailed interface 814 shown in Figure 8B takes into account that, in this example, the testing conducted on the plurality of optical fibers in the optical multifiber communication link 802 includes testing at more than one optical wavelength, such as 1310 nm and 1550 nm. The detailed interface 814 includes tabbed pages 828 that enable a user to selectively display measured values of parameters of the optical fibers according to a selected optical wavelength. In Figure 8B, the tab 828 for testing conducted using test signals at 1310 nmis selected. The detailed interface may also include a tab 828 for selectively showing measured length of the optical fibers that were tested.

[0097] Figures 9A and 9B illustrate another example of a multistage test result interface according to the present disclosure, including a summary interface 900 (Figure 9A) and a detailed interface 914 (Figure 9B), wherein the test result interface in this example indicates a failing grade 912.

[0098] In this example, the summary interface 900 depicts an optical multifiber communication link 902 coupled between a main optical device 904 and a remote optical device 906. As with the optical multifiber communication link 802 shown in Figure 8A, the optical multifiber communication link 902 is represented by a single graphical line representing the overall communication link. The graphical depiction of the optical communication link 902 includes an indication 910 informing the user that the optical multifiber communication link 902 includes twenty-four optical fibers.

[0099] As with the summary interface 800 in Figure 8A, the summary interface 900 in Figure 9A includes limited information, without displaying graphical representations of all of the individual optical fibers that were tested and their corresponding test results. In this example, the summary interface 900 includes a test result 908 of one or more measured parameters (e.g., optical loss, fiber length, and / or link polarity) of an optical fiber among the plurality of the optical fibers that were tested.

[0100] In some implementations, the summary interface 900 provides the test result 908 for only one optical fiber of the plurality of optical fibers in the optical communication link 902. By presenting a limited amount of test results, e.g., a test result for a single “worst case” optical fiber, the summary interface 900 allows the user to quickly evaluate the testing performed and determine if viewing more detailed information would be helpful. In cases where one or more of the test results fail to satisfy or fall within specified limits of a standard, the test results for the communication link 902 may be given a “failing” grade, e.g., as illustrated at 912. In any case, the user can choose to transition from the summary interface 900 to a detailed interface 914, to view more detailed information as shown in Figure 9B. A tap or swipe on the test results 908, or other user input to the summary interface 900, may act as a trigger or otherwise cause the multistage test results interface to transition 913 to the second stage in which the detailed interface 914 is shown.

[0101] Generally, though not required, when the detailed interface 914 is displayed, the detailed interface 914 replaces the summary interface 900. The detailed interface 914, in the example shown, depicts graphical representations 916 (e.g., in the form of a bar chart) of measured values for the plurality of optical fibers. The chart in this example graphically depicts the measured values of optical loss as measured in the twenty -four optical fibers in the optical multifiber communication link. The optical loss is shown according to a scale 920 from 0 to 4 dB. The detailed interface 914 also includes a numeric representation 924 of a measured value for each of one or more optical fibers in a subset of the plurality of optical fibers (here, for example, optical fiber #08). As with previous discussion herein, the subset includes less than allof the plurality of optical fibers that were tested. Additionally, the detailed interface 914 includes a focus indicator 922 indicating the one or more optical fibers in the subset.

[0102] In this example, diagonal hashmarks (representing a color such as green) indicate optical fibers for which the measured optical loss does not exceed a maximum threshold optical loss (e.g., according to a specified limit as represented in the chart by a horizontal line). The optical fibers for which the measured optical loss exceeds the threshold (here, for example, optical fibers #08, #14, #19, and #20) are shown by horizontal hashmarks (representing a color such as red), confirming that the optical fibers, considered together, collectively “fail” the optical loss aspect of the test, which may be defined by a predetermined standard.

[0103] By way of the detailed interface 914, the apparatus 102 provides, on the display 106, a numeric representation 924 of a measured value for each of the one or more optical fibers in the subset indicated by the focus indicator 922. The focus indicator 922, in this instance, is a rectangular box that graphically encompasses the one or more optical fibers (here, optical fiber #08) in the subset. As described herein (e.g., with respect to Figures 8 A and 8B), the number of optical fibers and which of the optical fibers are included in the subset is adjustable, e.g., according to a user input such as a swipe, tap, or zoom gesture, received by the processor 108.

[0104] To aid in identifying the optical fibers that are represented in the detailed interface 914, the graphical representation shown may include or otherwise be annotated to include numerals 918. The example shown in Figure 9B depicts numerals 1-24 indicating optical fibers #01-#24.

[0105] As previously noted, in the detailed interface 914, the focus indicator 922 is positioned with respect to one or more of the graphical representations to indicate the one or more optical fibers in the subset for which numerical measured values 924 are shown. The processor 108 is configured to adjust, based on user input, which optical fibers of the plurality of optical fibers are in the subset and correspondingly modify the focus indicator 922 such that the focus indicator consistently indicates the optical fibers that are in the subset.

[0106] In some cases, the user input may be a swipe gesture and in response to receiving data indicating the swipe gesture, the processor 108 is configured to modify the positioning of the focus indicator 922 to indicate a different subset of optical fibers in the plurality of optical fibers.

[0107] In some cases, the user input may be a tap gesture on a directional icon 926, and in response to receiving the data indicating the tap gesture, the processor 108 is configured to modify the positioning of the focus indicator 922 to indicate a different subset of optical fibers in the plurality of optical fibers according to the directional icon 926 tapped by the tap gesture. When the focus indicator is modified (e.g., moved) to include a different optical fiber in the subset, the numerical values 924 are updated to reflect the measured numerical values of parameters measured for the optical fiber(s) that are currently in the subset.

[0108] In some cases, the user input may be a zoom gesture, and in response to receiving data indicating the zoom gesture, the processor 108 is configured to enlarge or reduce a size of the focus indicator 922 and correspondingly enlarge or reduce the number of optical fibersincluded in the subset. For example, if the focus indicator 922 were enlarged, it may encompass optical fibers #08 and #09. The numerical values 924 would be updated to reflect the measured numerical values of parameters measured for optical fibers #08 and #09.

[0109] In some cases, the user input is a tap gesture indicating a particular graphical representation of a measured value for a particular optical fiber, and in response to receiving data indicating the tap gesture, the processor 108 is configured to modify the positioning of the focus indicator 922 to include the particular optical fiber in the subset of optical fibers. If, for example, the user tapped on optical fiber #12 in the chart 916, the processor 108 would modify the positioning of the focus indicator 922 to encompass the graphical representation for optical fiber #12 and the numerical values 924 would be updated to reflect the measured numerical values of parameter(s) of optical fiber #12.

[0110] As illustrated, the focus indicator 922 may include a bordered perimeter that encompasses the graphical representations of measured values of the one or more optical fibers (for example, in Figure 9B, optical fiber #08) in the subset. In some cases, as previously described, the apparatus is integrated into an optical fiber testing tool that includes a fiber connection interface couplable to a connector of the optical multifiber communication link.[OHl] The detailed interface 914 shown in Figure 9B takes into account that, in this example, the testing conducted on the plurality of optical fibers in the optical multifiber communication link 902 includes testing at more than one optical wavelength, such as 1310 nm and 1550 nm. Tabbed pages 928 enable a user to selectively display measured values of parameters of the optical fibers according to a selected optical wavelength. In Figure 9B, the tab 928 for testing using test signals at 1310 nm is selected. The detailed interface may also include a tab 928 for selectively showing measured length of the optical fibers that were tested.
