Description

Background Technology Technical Field

[0001] This disclosure relates to apparatus and methods for transmitting test results from a test optical multifiber communication link. Related technical descriptions

[0002] Optical fibers are commonly deployed in communication networks such as telephone networks, cable systems, and computer communication networks used for high-speed data communication (e.g., the Internet). To address the ever-increasing demands for bandwidth and communication throughput, optical communication links between endpoints in such networks increasingly incorporate optical fibers. Multi-fiber communication cables allow for the rapid deployment of even larger numbers of fibers. These cables are terminated by connectors such as ceramic sleeves or diaphragm adapters, which enable the joint addition, removal, or deployment of multiple fibers within the communication network. When the connectors of the multi-fiber communication cable are coupled to the corresponding ports of transmitting and receiving network equipment, the connectors align the fibers with the corresponding optical communication components within the network equipment. High-density multi-fiber communication links comprising 16, 24, or more fibers are emerging.

[0003] Optical fiber enables high-speed data transmission with relatively low loss. After installing an optical communication link, it is important to test the link to confirm and / or verify that the optical fibers in the link are correctly aligned, configured, and capable of successfully transmitting data within the expected parameters. One such parameter could be the measured loss of optical power in the optical signal transmitted over the fiber. Other parameters could be the measured length of each fiber being tested and / or the polarity of the fiber connections in the optical communication link. Testing can determine whether there are faults in the optical communication link that could reduce or prevent successful data transmission during installation. In some cases, the measured parameters of the optical fibers in the optical communication link are compared to specified limits (e.g., benchmarks) of one or more standards. Such standards can be locally generated or third-party standards that set objective requirements for optical communication links, published by organizations such as the International Electrotechnical Commission (IEC) or various other organizations. Other organizations that publish standards include the Telecommunications Industry Association (TIA), Technical Standards Boards (TSBs), the International Organization for Standardization (ISO), and the Institute of Electrical and Electronics Engineers (IEEE).

[0004] In some cases, contamination of the fiber end face or defects within the fiber itself can lead to optical power loss in the optical signal transmitted via an optical communication link. Such defects can block, diffuse, or misdirect the optical signal, thereby affecting signal quality, for example, by reducing signal strength or introducing artifacts into the signal during transmission. Optical power loss may exceed specified limits of predetermined standards, such as a threshold maximum power loss. In other examples, the length of the fiber optic cable may exceed a specified maximum length and / or misconnections of fibers in the optical communication link may lead to incorrect polarity, resulting in link failure.

[0005] When displaying test results from tests conducted on multi-fiber communication links, many displays are not large enough to simultaneously display all test results for all fibers in the optical communication link at the desired resolution, especially for high-density multi-fiber communication links comprising 16, 24, or more fibers. There is at least a need for an improved test results interface for conveying test results from multi-fiber communication links, which allows users to more easily and efficiently view and understand the overall test results, while also providing improved capabilities for users to evaluate the test results of one or more individual fibers within the multi-fiber communication link. Summary of the Invention

[0006] The embodiments and examples described herein provide improved apparatus and methods for transmitting test results from tests performed on optical multifiber communication links. The advantages obtained through this disclosure are particularly evident when transmitting test results from high-density optical multifiber communication links consisting of, for example, 16, 24, or more optical fibers.

[0007] In at least one aspect, this document describes an apparatus comprising an optional display and a processor communicating with the display. The processor is configured, for example by circuitry or executable instructions, to receive test results from tests performed on multiple optical fibers. The optical fibers may be bundled together or otherwise arranged in an optical multi-fiber communication link. The processor generates a multi-level test result interface for transmitting the test results.

[0008] In at least one aspect, at the first level, the multi-level test results interface provides a summary interface on the display, which includes summary test results but does not include individual test results for all fibers in a multi-fiber optical link. The summary test results may be measurement parameters of the fibers among the fibers in a multi-fiber optical communication link. In some cases, the summary interface may include features such as a simplified graphical representation of the multi-fiber optical communication link and / or indications of whether the test results for the multi-fiber optical communication link meet or otherwise collectively meet specified limitations (e.g., benchmarks) of a predefined standard. At the second level, the multi-level test results interface provides a detailed interface on the display, which includes features such as representations of two or more fibers from a subset of the multi-fiber optical links. This representation may be a graphical representation of two or more fibers from a subset of the multi-fiber optical links (e.g., as connected in a multi-fiber optical communication link). In this respect, the fiber subset includes fewer than all fibers in the multi-fiber optical link. The representation of the two or more fibers in the subset includes test results for the two or more fibers, such as measurement parameters. The detailed interface may also include a map identifying the distribution of the two or more fibers shown, such as a graphical distribution map. The detailed interface indicates which of the multiple optical fibers is adjustable, for example, based on user input.

[0009] On the other hand, this document describes a method for displaying test results for an optical multi-fiber communication link. The method includes receiving test results from tests performed on multiple optical fibers in the optical multi-fiber communication link, and providing a multi-level test result interface on a display. The multi-level test result interface includes a first level and a second level. In at least one aspect, in the first level, the multi-level test result interface provides a summary interface on the display. The summary interface includes test results for at least one measurement parameter of the optical fiber among the multiple optical fibers. In the second level, the multi-level test result interface provides a detailed interface on the display. The detailed interface shows a graphical representation of two or more optical fibers from a subset of the multiple optical fibers. The graphical representation includes test results for the measurement parameters of the two or more optical fibers. The specific optical fiber represented and shown in the detailed interface can be adjusted according to user input.

[0010] On the other hand, this paper describes a method for generating a multi-level test result interface for transmitting test results. The method includes receiving test results from tests performed on multiple optical fibers in an optical multi-fiber communication link, and generating a multi-level test result interface on a display. Generating the multi-level test result interface includes, in a first level, providing a summary interface on the display. While the summary interface includes summary test results, it does not include individual test results for each of the multiple optical fibers.

[0011] The multi-level test results interface also includes a detailed interface provided on the display in a second level. In at least one aspect, the detailed interface includes a representation of two or more fibers from a subset of the multiple fibers. This representation includes test results for the two or more fibers in the subset. The subset includes fewer than all fibers from the multiple fibers.

[0012] In response to receiving a trigger command, the multi-level test results interface changes from providing a summary interface on the display to providing a detailed interface on the display. In at least one aspect, the method further includes adjusting which of the multiple optical fibers are in a subset and displayed in the detailed interface based on user input.

[0013] These concepts and features, as well as other concepts and features, are illustrated by various embodiments and specific implementations of this disclosure as described herein. Attached Figure Description

[0023] In any network setup, it is valuable to test communication links, such as multi-fiber optical communication links, to confirm and / or verify that the communication link is correctly configured and capable of successfully transmitting data, for example, within the specified limits of a predetermined standard. This includes testing high-density multi-fiber optical communication links comprising 16, 24, or more optical fibers. After testing a communication link with a large number of optical fibers, it is important to display the test results on a monitor in a manner that is easy to read and interpret (i.e., not cluttered or confusing for the user) and ultimately useful to the user.

[0024] This document discloses apparatus and methods for transmitting test results for an optical multifiber communication link in a multi-level test results interface. The optical multifiber communication link includes multiple optical fibers connected between communication endpoints, for example, by coupling connectors of a multifiber communication cable between an optical transmitter and an optical receiver. As will be described herein, in a first level, the multi-level test results 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 collection link, for example, without graphically representing individual optical fibers in the optical multifiber communication link. The summary interface includes at least one test result for a measurement parameter obtained from the optical fiber in the tested optical multifiber communication link. In at least one example, the summary interface includes test results for a measurement parameter obtained from an optical fiber within the optical fiber of the optical multifiber communication link. The summary interface can, for example, be configured to display the test results for a "worst-case" fiber related to the measurement parameters of the fiber under test.

[0025] In the second level following the first level, the multi-level test results interface provides a detailed interface on the display. In at least one example, the detailed interface shows a graphical representation of a subset of multiple optical fibers in a multi-fiber communication link, for example, a graphical representation of two or more individual optical fibers in the link. This graphical representation includes the test results for the measurement parameters of the two or more optical fibers in the subset. In some cases, the user can adjust which optical fibers are represented in the detailed interface. In this way, the user can view the test results for a subset of optical fibers in the multi-fiber communication link (i.e., fewer than all fibers) and adjust or modify the detailed interface as needed to view different subsets of optical fibers. While all test results for multiple optical fibers are available to be viewed in the detailed interface in individual subsets, the user can selectively view the test results to focus the detailed interface on one or more specific subsets of optical fibers of interest. For example, the user may want to focus on an optical fiber that failed to meet specified limitations, such as those of a predetermined standard, during testing. The user can easily navigate through the test results for individual optical fibers and focus on relevant test results for subsets of optical fibers without having to view all test results for all optical fibers in the multi-fiber communication link simultaneously.

[0026] In another example, the multi-level test results interface includes a first level, where a summary interface is provided on the display. The summary interface includes summary test results but does not include all measurements for all fibers in the multiple fibers. The multi-level test results interface also includes a second level, where a detailed interface is provided on the display. The detailed interface includes a graphical representation of the measurements for some or all of the multiple fibers, a numerical representation of the measurements for each fiber in a subset of the multiple fibers, and a focus indicator indicating the one or more fibers in that subset. The graphical representation can, for example, be arranged in a graph displaying the test results of the fiber measurement parameters. This subset includes fewer than all fibers in the multiple fibers. In response to a trigger command, the multi-level test results interface transitions from the summary interface to the detailed interface. Advantageously, in an advantageous embodiment, the one or more fibers in the subset indicated by the focus indicator are adjustable.

[0027] Users can selectively point the focus indicator to one or more specific fibers in the detailed interface to view digital measurements for that particular fiber. Users can thus focus various aspects of the detailed interface on one or more fibers of interest. For example, a user might want to focus on a fiber that failed to meet specified limits (thresholds or other benchmarks) during testing, such as those of a predetermined standard. Users can easily navigate through the test results for individual fibers and focus on relevant test results for a specific fiber, without having to view all the values ​​of all parameters measured for all fibers in a multi-fiber optical communication link simultaneously.

[0028] As will be described herein, the multi-level test results interface according to aspects of this disclosure therefore includes (1) a summary interface displayed in a first level, and (2) a detailed interface displayed in a second level. The summary interface provides limited test results, for example, for a single fiber optic cable in a multi-fiber optical communication link under test, while the detailed interface provides additional information for multiple fibers (and in some cases, fewer than all fibers) in the multi-fiber optical communication link. In this way, the test results are presented to the user in a way that is easier to read, less cluttered, and more effectively interpreted, which is more useful to the user. If the user wishes to see more detailed information, the user can navigate from the summary interface to the detailed interface.

[0029] In some cases, the multi-level test results interface displays a summary interface until a command is received, and in response to a command, the multi-level test results interface provides a detailed interface. For example, if all test results for the optical fibers in a multi-fiber communication link are satisfactory—that is, if the test results for all fibers meet the specified limits of a standard and the result is a "pass grade"—the user can choose not to view more detailed information in the detailed interface. The user can immediately continue to view test results from different tests, possibly for different communication links. On the other hand, if, for example, some test results fail to meet the specified limits of a standard, a "failure grade" can be assigned to the test results for the communication link, 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 multi-level test results interface comprises at least two sections or areas on the display. The first section includes a graphical representation of two or more optical fibers (i.e., a subset of fibers less than all fibers) in the multi-fiber optical communication link. The second section includes a graphical distribution of an array of icons, where each icon corresponds to a specific fiber in the multi-fiber optical communication link. The second section also includes a selection window positioned relative to the icon array, which identifies those icons corresponding to the two or more fibers shown in the first section. Through user input, the user can adjust which fibers are graphically represented in the first section, which correspondingly modifies the position of the selection window in the second section. Similarly, through user input, the user can modify the position of the selection window in the second section, which correspondingly adjusts which fibers are graphically represented in the first section. Thus, the display of individual fibers in the first section is guided according to the user's interest, and such fibers shown in the first section are consistently identified in the second section by their corresponding icons within the selection window. Users can easily navigate and view test results for a desired subset of fibers in the communication link, for example, to focus on fibers whose test results fail to meet specified limits of a standard.

[0031] In some cases, users can provide input via swipe gestures, which adjust which optical fibers are graphically represented in the details interface. In response to a swipe gesture, the first section of the details interface can be modified to show a graphical representation of different subsets of optical fibers in a multi-fiber communication link, and the selection window can be repositioned relative to the icon array in the second section of the details interface to consistently identify the icons corresponding to the fibers shown in the first section. Swipe gestures are generally intuitive for users, allowing them to easily navigate and adjust which optical fibers and their corresponding test results are displayed in the details interface.

[0032] In some cases, user input may include zoom gestures (e.g., via tap, pinch, or expand gestures) to enlarge or shrink the graphical representation of the optical fiber shown in the first section of the detail interface. For example, in response to a zoom gesture, the graphical representation of the optical fiber in the first section can be enlarged or shrunk, depending on whether the gesture is interpreted as zooming in or out. Correspondingly, the size of the selection window in the second section of the detail interface is enlarged or shrunk. Like swipe gestures, zoom gestures are generally intuitive for users. With zoom gestures, users can easily enlarge the graphical representation in the first section, helping them better view the desired optical fiber and corresponding test results. Users can also shrink the size of the graphical representation in the first section, helping them see a larger number of optical fibers and corresponding test results within the first section.

[0033] In some cases, the detailed interface displayed by the multi-level test results interface selectively shows test results for a specific parameter among multiple parameters for the fiber under test. For example, the detailed interface may selectively show the measured optical loss, fiber length, or polarity of the fiber in a multi-fiber communication link under test. User input may include sliding or scrolling navigation in the detailed interface to guide the focus indicator onto one or more specific fibers. The measurement parameters of one or more fibers in the focus indicator are displayed specifically. As the focus indicator is moved to surround other fibers, the measurement parameters shown in the detailed interface are adjusted to report test results only for the fibers in the focus indicator. The size of the focus indicator can also be enlarged or reduced to include or exclude fibers in a subset.

[0034] Turn to the attached diagram. Figure 1 This is a block diagram illustrating at least one example of an optical fiber test tool 100 including a device 102 according to the present disclosure. The device 102 is configured to transmit test results from tests performed on multiple optical fibers, such as in an optical multifiber communication link 116. The optical fiber test tool 100 includes an optical fiber connection interface 104 having a port 112. Figure 1In the diagram, port 112 is shown as connector 114 coupled to optical multifiber communication link 116. At the opposite end of the optical multifiber communication link 116, an optical fiber is shown coupled to 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 In the diagram, connector 118 of the optical multifiber communication link 116 is shown as port 122 coupled to the fiber optic connection interface 124 of the network device 120.

[0035] Device 102 includes an optional display 106, a processor 108, and a memory 110. Processor 108 is shown communicating with display 106 and memory 110. Memory 110 is a non-transitory computer-readable storage medium that, in many cases, stores executable instructions that, when executed by the processor, configure and cause the processor to perform tasks as described herein, including receiving test results from tests performed on multiple optical fibers in an optical multifiber communication link 116 and providing a multi-level interface of test results on display 106, as described herein. Processor 108 may include one or more processing devices (microprocessors, programmable controllers, application-specific integrated circuits, etc.) configured individually and / or collectively (whether by software programming or hardware) to perform the various processing tasks described herein.

[0036] In some embodiments, device 102 may be a multi-purpose device communicatively coupled to fiber optic test tool 100, such as a smartphone, tablet computer, laptop computer, or server computer. In some embodiments, device 102 may be integrated into fiber optic test tool 100.

[0037] The connection port 112 of the fiber optic test tool 100 can be configured to receive various types of connectors 114 coupled to different optical multifiber communication links 116 with the fiber optic cable under test. In some cases, the connection port 112 can be integrated into the fiber optic test tool 100. Each type of connector 114 can arrange the end faces of the optical fibers in the communication link 116 in a different array to achieve different polarities. For example, one type of connector 114 has sixteen optical fibers coupled to it, arranged in a single row. This type of connector 114 is considered to present a 1×16 array of fiber end faces to the fiber optic test tool 100.

[0038] Another type of connector 114 has twenty-four optical fibers coupled to it, arranged in double rows. This type of connector 114 is considered to present a 2×12 array of fiber end faces to the fiber optic test tool 100.

[0039] Another type of connector 114 has thirty-two optical fibers coupled to it, arranged in double rows. This type of connector 114 is considered to present a 2×16 array of fiber end faces to the fiber test tool 100. It should be understood that the connector 114 can be arranged in any desired array with any number of rows, columns, or other geometric arrangements in the optical multifiber communication link 116. It should also be understood that the fiber test tool 100 may include multiple different ports 112 to accommodate multiple different connectors 114.

[0040] In some cases, the fiber optic test tool 100 can be configured to detect the type of connector 114 received by the connection port 112 and identify from it a specific array of end faces presented by the connector 114 to the fiber optic test tool 100. For example, each type of connector 114 may have a different perimeter or profile, which can be mechanically or electronically detected by the fiber optic test tool 100, for example, using one or more electronic switches or visual recognition devices located in or around the connection port 112 of the fiber optic connection interface 104. Alternatively or additionally, the connector 114 may include circuitry that transmits data codes via wired or wireless communication to the connection port 112 or other parts of the fiber optic test tool 100, the data codes identifying a specific type of connector 114 and possibly identifying the polarity type of the optical multifiber communication link 116 coupled to the connection port 112.

[0041] In various specific implementations, the multi-level test result interface of this disclosure includes a first level that provides a summary interface on the display 106, for example, as described below. Figure 3A and Figure 4A As shown in the diagram. In the second level, the multi-level test results interface provides a detailed interface on display 106, for example, as... Figure 3B and Figure 4B As shown.

[0042] Compared to a conventional test results interface, the advantages of providing test results in a multi-level test results interface as described in this article can be understood. Figure 2 An example of a standard test results interface 200 is shown, displaying test results from a test pair of optical fibers 202. The optical fibers 202 are coupled between the host device 204 and the remote device 206.

[0043] The standard test results interface 200 displays representations and corresponding test results 208 and 210 for all tested optical fibers 202. In this example, test results 208 and 210 include the detected optical loss and the cable length of each fiber in the tested optical fiber. The optical fiber 202 shown is a single fiber. Additionally, in this example, the standard test results interface 200 displays information 212, such as the type of optical fiber being tested and test limitations or standards, which is used to evaluate test results 208 and 210. In this case, as shown, test results 208 and 210 are within the indicated standard test limitations, and therefore optical fiber 202 is assigned a pass rating 214. It is worth noting that the standard test results interface 200 does not include the summary interface as described herein, nor the detailed interface as described herein.

[0044] While the standard test results interface 200 may be useful when testing communication links with a limited number of optical fibers, the results differ when performing tests on a higher number of optical fibers, such as on high-density multi-fiber communication links with 16, 24, or more fibers. It is easy to understand that, given the number of individual optical fibers and corresponding test results shown in interface 200, the standard test results interface 200 becomes overcrowded and difficult to read in such cases.

[0045] In contrast. Figure 3A and Figure 3B This illustrates the multi-level test results interface provided by device 102 according to this disclosure. Figure 2 The interface for the standard test results is different from 200. Figure 3A and Figure 3B The multi-level test results interface first provides a summary interface 300 on the display 106. 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, transmitting and receiving optical signals between them. In some cases, the fiber optic test tool 100 may be the main optical device 304, and in other cases, the fiber optic test tool 100 may be the remote optical device 306.

[0046] The multi-fiber optical communication link 302 is indicated by graphical lines representing the entire communication link, rather than by multiple lines representing the individual optical fibers constituting the multi-fiber optical communication link 302. In at least some embodiments, the graphical depiction of the multi-fiber optical communication link 302 includes an indication 310 of the number of optical fibers in the optical communication link. In the example shown, indication 310 informs the user that the multi-fiber optical communication link 302 includes sixteen optical fibers.

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

[0048] If the test results for all optical fibers in the multi-fiber communication link 302 are satisfactory—for example, if the test results fall within or otherwise meet one or more specified limits of a predetermined standard—the summary interface 300 may display a "pass grade" 312. Conversely, if one or more test results fail to fall within or meet the specified limits of the predetermined standard, the test results for the multi-fiber communication link 302 may be assigned a "failure grade," for example, as discussed below. Figure 4A As shown in the diagram. In this way, the summary interface 300 includes an indication of whether the test results for the optical multifiber communication link collectively meet the specified limits of a predetermined standard. In any case, the user can choose to view more detailed information in the detail interface 314, such as... Figure 3B As shown, the test results of individual optical fibers in the optical multifiber communication link 302 are used to evaluate and better understand them.

[0049] In some cases, processor 108 provides a summary interface 300 on display 106 until processor 108 receives a trigger command, and in response to receiving the trigger command, processor 108 provides a detailed interface 314 on display 106. User input to the summary interface 300 (e.g., a tap or swipe on a summary test result 308) can cause a multi-level test result interface transition 313 to a second level where the display shows the detailed interface 314. Thus, in some cases, the summary interface 300 includes a summary portion containing at least one summary test result 308, and processor 108 receives a trigger command as a result of a user selection of the summary test result 308 to transition to the detailed interface 314.

[0050] Typically, although not required, the detailed interface 314 replaces the summary interface 300 when displayed. The detailed interface 314 shows a graphical representation of two or more individual optical fibers 316 within a subset of multiple optical fibers in the optical multifiber communication link 302. The two or more individual optical fibers 316 in the subset are fewer than all the optical fibers being tested. The graphical representation of the two or more optical fibers 316 is shown in a first part or area of ​​the display. The graphical representation may be a graphical wiremap showing the connection of the two or more optical fibers in the optical multifiber communication link 302.

[0051] exist Figure 3B In the example shown, a graphical representation of four optical fibers 316 is displayed in the upper or central portion of the display. The four optical fibers 316 shown are a subset of the sixteen optical fibers in the multi-fiber optical communication link 302. The graphical representation of the individual optical fibers within the subset shown in the first section includes test results of the fiber's measurement parameters.

[0052] Figure 3B The subset of the four optical fibers 316 shown includes, for example, the seventh, eighth, ninth, and tenth fibers of the sixteen fibers in the optical multifiber communication link 302. The four optical fibers 316 are coupled to the main optical device 304 at corresponding endpoints 318a, 320a, 322a, and 324a, and to the remote optical device 306 at corresponding endpoints 318b, 320b, 322b, and 324b. A graphical representation of the four optical fibers can be a wiring diagram indicating correct or incorrect coupling of the fibers according to the intended polarity of the optical multifiber communication link 302. The graphical wiring diagram illustrates the connection of the optical fibers 316 and the determination of whether the fibers are properly connected according to the intended polarity of the fibers in the optical multifiber communication link 302.

[0053] In this example, a hashmark (which may represent a color such as green or other visual indicators) indicates the “correct” connection of the four optical fibers shown. Each of the four depicted optical fibers 316 may also include corresponding test results 318c, 320c, 322c, 324c for each fiber, such as measured optical loss.

[0054] Through detailed interface 314, device 102 provides test results on display 106 for some (e.g., two or more) but not all optical fibers in the multi-fiber communication link 302. The subset of optical fibers 316 graphically represented in the first part of detailed interface 314 may include more or fewer than the four fibers shown. As will be further described below, the number of optical fibers, and which fibers are shown in the first part of detailed interface 314, can be adjusted, for example, based on user input received by processor 108 of device 102.

[0055] To aid in identifying a specific fiber optic cable represented at a given time in the first part of the detailed interface 314, the illustrated graphical representation may include, or be otherwise annotated, numbers including those within or adjacent to the endpoints. Figure 3B In the example shown, the numbers “7”, “8”, “9”, and “10” are depicted at the four ends of the four optical fibers 316, indicating the seventh through tenth fibers among the multiple fibers being inspected. However, such numbers are not required.

[0056] The detailed interface 314 also includes a second portion or area of ​​the display showing a graphical distribution map 328, which depicts an array of icons corresponding to the optical fibers of the tested multi-fiber communication link 302. Figure 3B In this embodiment, the second part is shown in the lower part of the display, below the first part; however, in other embodiments, the second part may be shown above or beside the first part. In this example, the graphic distribution diagram 328 includes sixteen circular icons, each corresponding to one of the sixteen optical fibers in the multi-fiber communication link 302. In this example, the processor 108 of device 102 has detected the type of connector 114 connected to the optical fiber connection interface 104 and identified that connector 114 is coupled to an optical cable with sixteen optical fibers arranged in a single row. Therefore, sixteen circular icons are shown in a single row in the graphic distribution diagram 328. In this way, the processor 108 can automatically generate the graphic distribution diagram 328 based on the fiber array identified by detecting the type of connector coupled to the connection port. Furthermore, in this embodiment, the graphic distribution diagram 328 depicts icons representing all the optical fibers coupled to connector 114, but in other embodiments (e.g., with a larger number of optical fibers arranged in a single row), the graphic distribution diagram 328 may be scrollable and depict only a portion of the icons at a given time.

[0057] A selection window 330 is also depicted in the second part of the detailed interface 314. The selection window 330 is positioned relative to the graphical distribution map 328 to identify one or more icons in the graphical distribution map 328 corresponding to the optical fibers 316 shown in the first part of the detailed interface 314 at a given time. In this example, where the first part is shown as displaying optical fibers "7" through "10", the selection window 330 surrounds the seventh through tenth icons in the graphical distribution map 328 and thus identifies the seventh through tenth optical fibers of the optical multifiber communication link 302. In various specific embodiments, the selection window 330 may include, for example... Figure 3B The selection window 330 is shown with a perimeter border, and the icon corresponding to fiber optic cable 316 is depicted within the perimeter border. In some cases, such as by using different line thicknesses, transparency levels, colors, patterns, or shadows, the icons within the perimeter border of the selection window 330 may appear different from those outside the perimeter border. As will be discussed in more detail below, the selection window 330 may span the graphic distribution diagram 328 and surround different icons depending on which fibers 316 are currently shown in the first part of the detail interface 314.

[0058] Figure 4A and Figure 4B A multi-level test result interface provided by the apparatus 102 according to this disclosure is shown. This multi-level test result interface includes a summary interface 400 and a detailed interface 414, wherein the test result interface in this example indicates a failure level 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. Figure 3A Similar to the illustrated multi-fiber optical communication link 302, the multi-fiber optical communication link 402 is represented by a single graphic line indicating the entire communication link. The graphic depiction of the optical communication link 402 includes an indication 410 that informs the user that the multi-fiber optical communication link 402 comprises sixteen optical fibers.

[0059] and Figure 3A The summary interface is the same as 300. Figure 4A The summary interface 400 includes limited information and does not display a graphical representation of all individual optical fibers being tested and their corresponding test results. In this example, the summary interface 400 includes test results 408 for one or more measurement parameters (e.g., optical loss, fiber length, and / or link polarity) of the multiple optical fibers being tested.

[0060] In some implementations, the summary interface 400 provides test results 408 for only one of the multiple optical fibers in the optical communication link 402. By presenting a limited number of test results (e.g., test results for a single "worst-case" fiber), the summary interface 400 allows users to quickly assess the performed tests and determine if viewing more detailed information would be helpful. If one or more test results fail to fall within the specified limits of the standard, a "failure grade" can be assigned to the test results for the communication link 402, for example, as shown at 412. In any case, the user can choose to switch from the summary interface 400 to the detailed interface 414 to view more detailed information, such as... Figure 4B As shown.

[0061] A tap or swipe on the test result 408, or other user input on the summary interface 400, causes the multi-level test result interface 313 to transition to a second level where the detailed interface 414 is displayed. Figure 3B The detailed interface is the same as 314. Figure 4B The detailed interface 414 shows a graphical representation of four individual optical fibers 416, a subset of the multiple optical fibers in the optical communication link 402. Individual optical fibers 416 are graphically represented in a first portion or area of ​​the display (e.g., the upper or central area of ​​the display). The four optical fibers shown are a subset of the sixteen optical fibers in the optical communication link 402. By default, the multi-level test results interface can automatically initially select to show optical fibers 416 that include the fiber representing the “worst-case” among the test results for the optical fibers in the optical communication link 402, for example, as indicated by test results 408 shown in the summary interface 400.

[0062] Figure 4B The subset of the four optical fibers 416 shown includes the seventh, eighth, ninth, and tenth fibers of the sixteen fibers in the communication link 402, which are coupled between the main optics 404 at corresponding endpoints 418a, 420a, 422a, and 424a and the remote optics 406 at corresponding endpoints 418b, 420b, 422b, and 424b. Depending on the intended polarity of the communication link 402, the graphical representation of the four fibers can be a wiring diagram indicating incorrect coupling of the fibers. In this example, vertical shadow markings (which may represent a color such as red or other visual indicators) indicate an “incorrect” or faulty connection of the seventh and eighth fibers. The seventh fiber is connected between the seventh endpoint 418a and the eighth endpoint 420b, while the eighth fiber is connected between the eighth endpoint 420a and the seventh endpoint 418b. Each of the four fibers 316 depicted includes corresponding test results 418c, 420c, 422c, and 424c for the fiber under test, such as measured optical loss.

[0063] Although the seventh and eighth fibers are indicated by vertical shadow markings as incorrectly connected and therefore failing to support the intended polarity of communication link 402, the tenth fiber is also indicated by vertical shadow markings as failing to meet expectations. In this case, although the tenth fiber is properly connected between the main endpoint 424a and the remote endpoint 424b, the tenth fiber has a test result 424c reporting optical loss exceeding the optical loss test limits of the applied standard. Therefore, the seventh, eighth, and tenth fibers in this example contribute to a "failure" level 412.

[0064] Similar to detailed interface 313, detailed interface 414 has a second portion or area including a graphical distribution map 428. Graphical distribution map 428 depicts a 1×16 array of icons representing the sixteen optical fibers of communication link 402. Selection window 430 is positioned relative to graphical distribution map 428 to identify the icons in graphical distribution map 428 corresponding to the seventh through tenth optical fibers currently shown in the first portion of detailed interface 414. Specifically, selection window 430 includes a perimeter with a border surrounding the seventh through tenth icons in graphical distribution map 428. Selection window 430 may span graphical distribution map 428 and surround different icons depending on which optical fibers 416 are currently shown in the first portion of detailed interface 414.

[0065] Figure 5A and Figure 5B Features of detailed interfaces 314, 414 of this disclosure are shown, in which a user can adjust which optical fibers are graphically represented in the detailed interface based on trigger signals such as user input. In this example, the trigger signal (e.g., user input) is in the form of a swipe gesture 500.

[0066] In some implementations, device 102 may be configured such that at least a portion of display 106 is a touchscreen. User input detected by the touchscreen may be a swipe gesture generated by the user's finger or other tool that interacts with the touchscreen and moves across its surface. In response to receiving data indicating a swipe gesture from the touchscreen, processor 108 may be programmed to modify a first portion of detail interface 414 to show a graphical representation of different subsets of optical fibers, and also modify the position of selection window 430 relative to the graphical distribution map 428 in a second portion of detail interface 414, such that selection window 430 consistently identifies icons in graphical distribution map 428 corresponding to specific optical fibers graphically represented in the first portion of detail interface 414.

[0067] For example, the display 106 can detect a swipe gesture 500 indicating a movement in the right direction toward the right side of the display, such as... Figure 5A and Figure 5BAs shown in the example. In response to receiving data indicating a swipe gesture, processor 108 can cause a first portion of detailed interface 414 to display a subset of the optical fibers to the right of the previously shown optical fibers. Figure 5B In the first part, a subset of optical fibers 502 is shown as shifted to the right, as demonstrated by the shift from showing the seventh to the tenth optical fibers to showing the tenth to the thirteenth optical fibers (as indicated by the numbers “10” to “13” at endpoints 424a, 432a, 434a, 436a and the corresponding endpoints 424b, 432b, 434b, 436b).

[0068] It is worth noting that, in response to receiving data indicating a swipe gesture 500, the processor 108 also modifies the second part of the detailed interface 414 to show a selection window 430 repositioned to the right of the graphic distribution map 428. Figure 5B In the graphic distribution diagram 428, the selection window 430 is identified (e.g., by surrounding it) as the tenth to thirteenth icons in the icon array of the sixteen optical fibers in the optical multi-fiber communication link 402. This is achieved by repositioning the selection window 430 in the graphic distribution diagram 428 (by...). Figure 5A The position of the selection window 430 shown is... Figure 5B (Comparing the positions shown), a user viewing the detailed interface 414 can easily identify which fibers of the optical multifiber communication link 402 are currently displayed in the first part of the detailed interface 414. As can be readily understood, this is particularly useful in examples of multi-level test result display interfaces that do not include the identification numbers in the endpoints shown in the first part of the detailed interface 414. In such examples, the user can see which icons are within the selection window 430 and easily identify which fibers are currently graphically represented in the first part of the detailed interface 414.

[0069] When the user input is a swipe gesture 500 indicating movement in the left direction toward the left side of the display 106, similar processing is applied. In response, the processor 108 causes the first portion of the detail interface 414 to show a subset of the optical fibers shifted to the left. Correspondingly, the processor 108 also causes the second portion of the detail interface 414 to reposition the selection window 430 in the left direction toward the left side of the graphic distribution map 428. For example (although not shown), the selection window 430 can be shifted to surround the fifth through ninth icons in the graphic distribution map 428, thereby indicating that optical fibers "5" through "9" are shown in the first portion of the detail interface 414.

[0070] Figure 6A and Figure 6BAnother feature of the detailed interfaces 314, 414 of this disclosure is shown, in which a user can adjust the size of a graphical representation of a subset of optical fibers shown in the first part of the detailed interface based on a trigger signal such as a user input in the form of a zoom gesture.

[0071] In a specific implementation where display 106 is a touchscreen, display 106 can detect zoom gestures 600 caused by user interaction with the display or a portion thereof (e.g., touch on the display). Different contexts of the display can produce different interpretations of a tap gesture. For example, in Figure 4A A tap gesture on the overview interface 400 can cause a transition 313 from the overview interface 400 to the detail interface 414. A tap gesture on the detail interface 414 can cause a zoom operation. Similarly, a pinch or expand gesture 600 can cause a zoom operation.

[0072] In response to receiving data indicating a "zoom in" gesture, processor 108 is programmed to modify a first part of detailed interface 414 (e.g., as...). Figure 6A (As shown) so that it looks like Figure 6B The first section shown here features an enlarged graphical representation of a specific optical fiber. This enlarged representation makes it easier to see the test results for certain fibers. Figure 6B In the example, a larger representation of the ninth and tenth fibers is shown. Similarly, a zoom gesture can be interpreted as a "shrink" gesture, which modifies the first portion of detail interface 414 to show a reduction in the size of the graphical representation of the illustrated fibers, for example from... Figure 6B The expanded representation in the middle is transformed into Figure 6A The reduced size representation in the text.

[0073] In response to receiving data indicating a "zoom in" or "zoom out" gesture, processor 108 is also programmed to modify the size of selection window 430 in the second part of detail interface 414. For example, in response to a "zoom in" gesture 600, Figure 6B The selection window 604 in the middle has been modified, and it is now consistent with... Figure 6A The selection window in the middle (430) appears smaller in size compared to the previous one. Figure 6B In the example, selection window 604 surrounds only the ninth and tenth icons in the graphic distribution diagram 428, corresponding to the graphic depictions of the ninth and tenth optical fibers in the first part of the detail interface 414. In this way, selection windows 430 and 604 consistently identify one or more icons in the graphic distribution diagram 428 corresponding to the optical fibers shown in the first part of the respective detail interface 414.

[0074] The "zoom out" gesture causes processor 108 to reduce the size of the optical fiber, which is graphically represented in the first part of the detail interface. In response to the "zoom out" gesture, different, larger subsets of the reduced-size optical fibers can be displayed in the first part based on the details of the "zoom out" gesture (e.g., range). Processor 108 is also programmed to modify the size of selection window 604 in the second part of the detail interface 414, such that the selection window is displayed as larger in size, for example, as... Figure 6A The selection window 430 is shown in the middle. Therefore, the selection window in the second part of the display can consistently identify one or more icons in the graphic distribution diagram 428 corresponding to the optical fibers shown in the first part of the detailed interface 414.

[0075] When the user input is a tap gesture, the tap gesture can indicate the selection of a specific icon in the graphical distribution diagram depicted in the second part of the detail interface. In response to receiving data indicating such a tap gesture, the processor 108 can be configured to modify the first part of the detail interface to show a graphical representation that includes at least the optical fiber corresponding to the specific icon. The processor 108 can also reposition the selection window relative to the icon array in the second part of the detail interface, such that the selection window consistently identifies the icon corresponding to the optical fiber graphically represented in the first part of the detail interface.

[0076] Generally, the processor 108 in device 102 is expected to respond to swipe or zoom gestures in real time or near real time. For example, when a user interacts with display 106 and inputs a swipe gesture, the graphical representations of optical fibers 502, 602 shown in the first part and the corresponding selection windows 430, 604 move to the right or left in coordination with the swipe gesture (in this example) as the user swipes across the display. Such movement of the representations of optical fibers 502, 602 and selection windows 430, 604 can be faster or slower, depending on the speed of movement of the swipe gesture. In the case where the optical fibers of a multi-fiber communication link are arranged in two or more rows (e.g., in a 2×12 array or a 2×16 array of fiber end faces) in the corresponding connectors, a two-dimensional swipe gesture can cause the graphical representations of optical fibers 502, 602 in the first part to shift in a two-dimensional manner, and correspondingly cause the selection windows 430, 604 in the second part to shift in a two-dimensional manner (e.g., shift between the first and second rows in a graphical distribution diagram (not shown)). Similarly, zoom-in or zoom-out gestures can produce a graphical representation of the fiber in the first part being enlarged or reduced in size in more than one line, while the size of the selection window in the second part changes accordingly (larger or smaller in two dimensions).

[0077] In view of the foregoing description, it should be understood that this disclosure considers innovative methods for displaying test results for optical multifiber communication links. Figure 7This is a flowchart illustrating an example of a method 700 for generating a multi-level test result interface for transmitting test results according to the present disclosure. Method 700 includes receiving test results from tests performed on multiple optical fibers in an optical multi-fiber communication link (box 702), and providing a multi-level test result interface on a display. As described herein, the multi-level test result interface includes a first level of a summary interface provided on the display (box 704), wherein the summary interface includes test results for at least one measurement parameter of the optical fiber among the multiple optical fibers. The multi-level test result interface then provides a second level of a detailed interface provided on the display (box 706). The detailed interface shows a graphical representation of two or more optical fibers from a subset of the multiple optical fibers. The graphical representation includes test results for the measurement parameters of the two or more optical fibers. The optical fibers represented in the detailed interface are adjustable, for example, based on user input (box 708).

[0078] Such methods for transmitting test results for an optical multifiber communication link, as described herein, may further include: detecting the type of connectors having multiple optical fibers coupled to them in the optical multifiber communication link, and identifying an array of optical fibers coupled to the connectors based on the type of connectors; and automatically generating a graphical distribution diagram depicting the array of optical fibers in a detailed interface.

[0079] Figure 8A and Figure 8A Another example of a multi-level test results interface according to this disclosure is shown, wherein the test results interface includes a summary interface and a detailed interface, and in this example, the pass / fail level is indicated.

[0080] and Figure 2 Unlike the standard test result interface in 200, the multi-level test result interface first provides, for example, in the first level... Figure 8A The schematic interface 800 is shown. In this example, the schematic interface 800 depicts an optical multifiber communication link 802 coupled between a main optical device 804 and a remote optical device 806, transmitting and receiving optical signals between them. Optical signals at different wavelengths (e.g., 1310 nm and 1550 nm) can be transmitted and received during testing of the optical multifiber communication link 802. In some cases, the fiber optic test tool 100 ( Figure 1 The optical fiber test tool 100 can be a main optical device 804, and in other cases, it can be a remote optical device 806.

[0081] The optical multifiber communication link 802 is represented graphically as a whole communication link, rather than as individual optical fibers constituting the optical multifiber communication link 802. In at least some embodiments, 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 the example shown, 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 an overview of the test results. In this example, the summary interface 800 includes summary test results 808, such as the measurement parameters and / or pass / fail status of the fiber among multiple fibers being tested. Test results for multiple fibers include measured values ​​of the parameters measured during the test. The summary interface 800 does not include a representation of all individual fibers being tested, nor does it include all measurements for all fibers being tested, thus avoiding a cluttered test results interface that is difficult to read and evaluate. One or more measurement parameters shown in the summary test results 808 may be, for example, optical loss, fiber length, and / or communication link polarity. In some implementations, the summary interface 800 provides summary test results 808 for only one fiber among multiple fibers in an optical multi-fiber communication link 802. In some implementations, the test results shown may be for the fiber that presents the “worst” result related to the measurement parameters (such as optical loss) of all fibers being tested. By presenting a limited number of test results (e.g., test results for a single “worst-case” fiber), the summary interface 800 allows users to quickly assess the tests performed and determine whether it is helpful or necessary to view more detailed information.

[0083] If the test results for all optical fibers in the optical multifiber communication link 802 are satisfactory—for example, if the test results fall within or otherwise meet one or more specified limits of a predetermined standard—then the summary interface 800 displays a "pass grade" 812. Conversely, if one or more test results fail to fall within or meet the specified limits of the predetermined standard, the test results for the optical multifiber communication link 302 may be assigned a "failure grade," for example, as discussed below. Figure 9A As shown. In Figures 8A to 9B In the example shown, test limitations are specified according to the TIA-568-C multimode standard. In this way, the summary interface 800 includes an indication of whether the test results for the optical multifiber communication link 802 collectively meet the specified limitations of a predetermined standard. In any case, the user can select to view more detailed information in the detailed interface 814 based on the second level of the multi-level test results interface, such as... Figure 8B As shown, the test results of individual optical fibers in the optical multifiber communication link 802 are used to evaluate and better understand them.

[0084] In some cases, processor 108 ( Figure 1A summary interface 800 is provided on display 106 until processor 108 receives a trigger command, and in response to receiving the trigger command, processor 108 provides a detailed interface 814 on display 106. User input to the summary interface 800 (e.g., a tap or swipe on a summary test result 808) can cause a transition 813 of the multi-level test result interface to a second level in which the display shows the detailed interface 814. Thus, in some cases, the summary interface 800 includes a summary portion containing at least one summary test result 808, and processor 108 receives a trigger command as a result of a user selection of the summary test result 808 to transition to the detailed interface 814.

[0085] Typically, although not required, the detail interface 814 replaces the summary interface 800 when it is displayed. In the example shown, the detail interface 814 displays a graphical representation 816 of measurements for multiple optical fibers, a digital representation 824 of measurements for each of one or more optical fibers in a subset of the multiple optical fibers, and a focus indicator 822 indicating one or more optical fibers in the subset, which includes fewer than all the optical fibers.

[0086] In the example shown, a graphical representation 816 of the measurements for multiple optical fibers is arranged in a graph that graphically depicts the measurements of the twenty-four optical fibers in the multi-fiber optical communication link 802. In this case, the parameters shown are optical losses based on a scale 820 from 0 dB to 4 dB.

[0087] The focus indicator 822 indicates one or more fibers from a subset of multiple fibers, in this case fiber #08. In this example, the diagonal underline marker (which could represent, for example, a green color or other visual indicator) indicates that the measured optical loss in each fiber does not exceed the maximum threshold optical loss (in...). Figure 8B The specified limits are represented by horizontal lines on the chart, and therefore the optical fiber has acceptable optical loss and jointly meets or “passes” the optical loss aspect of the test (which may be defined by a predetermined standard).

[0088] Through detailed interface 814, device 102 provides on display 106 a digital representation 824 of the measurements for each of one or more optical fibers in a subset indicated by focus indicator 822. As shown, this subset includes all the optical fibers in fewer than the multiple optical fibers in the optical multi-fiber communication link 802. In this example, focus indicator 822 is a rectangular frame graphically surrounding one or more optical fibers in the subset (here, fiber #08). As will be further described below, the number of optical fibers in the subset and which fibers are included in the subset can be adjusted, for example, based on user input received by processor 108 of device 102.

[0089] To aid in identifying the optical fibers represented in detailed interface 814, the graphical representation may include, or be otherwise annotated, including the number 818. Figure 8B In the example shown, numbers 1 through 24 are depicted to indicate fiber optic cables #01 through #24. However, such numbers are not required.

[0090] As previously described, in the detailed interface 814, the focus indicator 822 is positioned relative to one or more graphical representations in the graphical representation to indicate one or more optical fibers for a subset of which it displays digital measurement values ​​824. The processor 108 is configured to adjust which optical fibers are in the subset based on user input and accordingly modify the focus indicator 822 such that the focus indicator consistently indicates the optical fibers in the subset.

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

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

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

[0094] In some cases, user input is a tap gesture indicating a specific graphical representation of a measurement for a particular fiber, and in response to receiving data indicating the tap gesture, processor 108 is configured to modify the positioning of focus indicator 822 to include the particular fiber in the fiber subset. For example, if the user taps on fiber #12, processor 108 will modify the positioning of focus indicator 822 to surround the graphical representation for fiber #12, and value 824 will be updated to reflect the measured value of the parameter measured for fiber #12.

[0095] As shown in the figure, the focus indicator 822 may include one or more optical fibers surrounding the subset (e.g., in...). Figure 8B The measurement value of fiber #08 is graphically represented by a perimeter with a boundary. In some cases, as previously described, the device is integrated into an optical fiber test tool that includes an optical fiber connection interface capable of coupling to connectors in a multi-fiber optical communication link. The optical 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 optical fibers arranged in an array. In this case, the processor 108 can be configured to detect the type of connector coupled to the connection port, and based on the connector type, identify the array in which the optical fibers are coupled to the connectors, and automatically determine and report the polarity of the optical fibers in the multi-fiber optical communication link.

[0096] Figure 8B The detailed interface 814 shown takes into account that, in this example, the tests performed on multiple optical fibers in the multi-fiber communication link 802 include tests at more than one optical wavelength (such as 1310 nm and 1550 nm). The detailed interface 814 includes tabs 828 that allow the user to selectively display measured values ​​of the fiber parameters based on the selected optical wavelength. Figure 8B In the interface, select label 828 for testing using a test signal at 1310 nm. The detailed interface may also include label 828 for selectively displaying the measured length of the fiber under test.

[0097] Figure 9A and Figure 9B Another example of a multi-level test results interface according to this disclosure is shown, which includes a summary interface 900. Figure 9A ) and detailed interface 914 ( Figure 9B In this example, the test results interface indicates a failure level of 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. Figure 8ASimilar to the illustrated multi-fiber optical communication link 802, the multi-fiber optical communication link 902 is represented by a single graphic line indicating the entire communication link. The graphic depiction of the optical communication link 902 includes an indication 910 that informs the user that the multi-fiber optical communication link 902 comprises twenty-four optical fibers.

[0099] and Figure 8A The summary interface is the same as 800. Figure 9A The summary interface 900 includes limited information and does not display a graphical representation of all individual optical fibers being tested and their corresponding test results. In this example, the summary interface 900 includes test results 908 for one or more measurement parameters (e.g., optical loss, fiber length, and / or link polarity) of the multiple optical fibers being tested.

[0100] In some implementations, the summary interface 900 provides test results 908 for only one of the multiple optical fibers in the optical communication link 902. By presenting a limited number of test results (e.g., test results for a single "worst-case" fiber), the summary interface 900 allows users to quickly assess the performed tests and determine if viewing more detailed information would be helpful. If one or more test results fail to meet or fall within specified limits of a standard, a "failure" rating can be assigned to the test results for the communication link 902, for example, as shown at 912. In any case, the user can choose to switch from the summary interface 900 to the detailed interface 914 to view more detailed information, such as... Figure 9B As shown. A tap or swipe on the test result 908, or other user input on the summary interface 900, can act as a trigger or otherwise cause the multi-level test result interface 913 to transition to a second level in which the detailed interface 914 is shown.

[0101] Typically, although not required, the detailed interface 914 replaces the summary interface 900 when displayed. In the example shown, the detailed interface 914 depicts a graphical representation 916 (e.g., in the form of a bar chart) of measurements for multiple optical fibers. The chart in this example graphically depicts measurements of optical loss, such as those measured in twenty-four optical fibers in a multi-fiber optical communication link. The optical loss is shown according to a scale 920 from 0 dB to 4 dB. The detailed interface 914 also includes a digital representation 924 of the measurements for each of one or more fibers (here, for example, fiber #08) in a subset of the multiple optical fibers. As discussed earlier herein, the subset includes fewer than all the fibers in the multiple optical fibers being tested. Additionally, the detailed interface 914 includes a focus indicator 922 indicating one or more fibers in the subset.

[0102] In this example, diagonal shaded markers (represented by 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 indicated by a horizontal line in a graph). Fibers for which the measured optical loss exceeds the threshold (here, for example, fibers #08, #14, #19, and #20) are indicated by horizontal shaded markers (represented by a color such as red), thus confirming that the fibers together are considered to have collectively "failed" in terms of the tested optical loss (which may be defined by a predetermined standard).

[0103] Through detailed interface 914, device 102 provides on display 106 a digital representation 924 of the measurement values ​​for each of one or more optical fibers in a subset indicated by focus indicator 922. In this example, focus indicator 922 is a rectangular frame graphically surrounding one or more optical fibers (here, fiber #08) in the subset. As described herein (e.g., regarding...), Figure 8A and Figure 8B The number of optical fibers and the subset of fibers that can be adjusted, for example, based on user input such as swipe, tap, or zoom gestures received by the processor 108.

[0104] To help identify the optical fibers represented in the detailed interface 914, the graphical representation shown may include or be annotated in other ways to include the number 918. Figure 9B The example shown depicts the numbers 1 to 24 indicating fiber optic cables #01 to #24.

[0105] As previously described, in the detailed interface 914, the focus indicator 922 is positioned relative to one or more graphical representations in the graphical representation to indicate one or more optical fibers in a subset for which it displays digital measurement values ​​924. The processor 108 is configured to adjust which optical fibers are in the subset based on user input and accordingly modify the focus indicator 922 such that the focus indicator consistently indicates the optical fibers in the subset.

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

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

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

[0109] In some cases, user input is a tap gesture indicating a specific graphical representation of a measurement for a particular fiber, and in response to receiving data indicating the tap gesture, processor 108 is configured to modify the positioning of focus indicator 922 to include the specific fiber in the fiber subset. For example, if the user taps on fiber #12 in diagram 916, processor 108 will modify the positioning of focus indicator 922 to surround the graphical representation for fiber #12, and value 924 will be updated to reflect the measured value of the parameters of fiber #12.

[0110] As shown in the figure, the focus indicator 922 may include one or more optical fibers surrounding the subset (e.g., in...). Figure 9B The measurement values ​​of fiber optic cable #08 are graphically represented with a perimeter bounded by the fiber optic cable. In some cases, as previously described, the device is integrated into an optical fiber test tool that includes an optical fiber interface capable of coupling to a connector for optical multi-fiber communication links.

[0111] Figure 9B The detailed interface 914 shown takes into account that, in this example, the tests performed on multiple optical fibers in the multi-fiber communication link 902 include tests at more than one optical wavelength (such as 1310 nm and 1550 nm). Tab 928 allows the user to selectively display measured values ​​of the fiber parameters based on the selected optical wavelength. Figure 9B In the interface, select tag 928 for testing using a test signal at 1310nm. The detailed interface may also include tag 928 for selectively displaying the measured length of the fiber under test.
