[0012] [Description of the First Embodiment] A first embodiment of the present invention will be described below. Fig. 1 is a block diagram showing the configuration of a visualization device QA and its peripheral devices according to the first embodiment. Fig. 2 is a schematic configuration diagram of a network system showing the connection of a transmission device TR equipped with a visualization device QA. This embodiment displays and visualizes information about a specific optical fiber selected by a user from a plurality of optical fibers that transmit optical signals.

[0013] In this embodiment, as shown in FIG. 1 and FIG. 2, a network system in which three transmission devices TR-1, TR-2, and TR-3 are connected by an optical fiber FB will be described as an example.

[0014] As shown in Fig. 2, each of the transmission devices TR-1, TR-2, and TR-3 includes a control unit 21, two transmission units 22a and 22b, two reception units RX, and a visualization device QA (QA1, QA2, and QA3), and performs data communication using optical fibers. The control unit 21 controls data communication by the transmission devices TR-1, TR-2, and TR-3. Detailed control will not be described. The transmission units 22a and 22b transmit optical signals to other transmission devices. The reception unit RX receives optical signals transmitted from other transmission devices.

[0015] 1, the visualization device QA includes a signal change detection unit 1, a connection database 2, and a display control unit 3. The signal change detection unit 1 is connected to two receiving units RX.

[0016] As shown in Fig. 2, the visualization device QA1 mounted on the transmission device TR-1 is connected to two receiving units RX-1-2 and RX-1-3. The visualization device QA2 mounted on the transmission device TR-2 is connected to two receiving units RX-2-1 and RX-2-3. The visualization device QA3 mounted on the transmission device TR-3 is connected to two receiving units RX-3-1 and RX-3-2.

[0017] The transmission devices TR-1 and TR-2 are connected by two optical fibers FB-1-2 and FB-2-1. That is, an optical signal transmitted from the transmitting unit 22b of the transmission device TR-1 is received by the receiving unit RX-2-1 via the optical fiber FB-1-2, and an optical signal transmitted from the transmitting unit 22a of the transmission device TR-2 is received by the receiving unit RX-1-2 via the optical fiber FB-2-1.

[0018] The transmission devices TR-2 and TR-3 are connected by two optical fibers FB-2-3 and FB-3-2. That is, an optical signal transmitted from the transmitting unit 22b of the transmission device TR-2 is received by the receiving unit RX-3-2 via the optical fiber FB-2-3, and an optical signal transmitted from the transmitting unit 22a of the transmission device TR-3 is received by the receiving unit RX-2-3 via the optical fiber FB-3-2.

[0019] The transmission devices TR-3 and TR-1 are connected by two optical fibers FB-3-1 and FB-1-3. That is, an optical signal transmitted from the transmitter 22b of the transmission device TR-3 is received by the receiver RX-1-3 via the optical fiber FB-3-1, and an optical signal transmitted from the transmitter 22a of the transmission device TR-1 is received by the receiver RX-3-1 via the optical fiber FB-1-3.

[0020] In the following, when each visualization device, each transmission device, each receiving unit, and each optical fiber is specifically indicated, they will be indicated with a suffix, such as "visualization device QA1," "transmission device TR-1," "receiving unit RX-1-2," and "optical fiber FB-2-1." When each visualization device, each transmission device, each receiving unit, and each optical fiber is not specifically indicated or is referred to collectively, they will be indicated without a suffix, such as "visualization device QA," "transmission device TR," "receiving unit RX," and "optical fiber FB."

[0021] As shown in Fig. 1, the receiving unit RX is connected to an optical fiber FB and receives an optical signal transmitted via the optical fiber FB. For example, the receiving unit RX-1-2 shown in Fig. 2 receives an optical signal transmitted from the transmitting unit 22a of the transmission device TR-2.

[0022] The receiver RX outputs the feature amount of the received optical signal to the signal change detector 1. The number of receivers RX mounted on one transmission device TR is not limited to two.

[0023] The characteristic quantities of the optical signal are, for example, the received light level of the optical signal, the variance of the multi-level modulation constellation, the bit error rate before error correction, etc. Information on these characteristic quantities can be acquired through DMM (Digital Diagnostic Monitoring) and TAI (Transponder Abstraction Interface).

[0024] The signal change detection unit 1 analyzes the feature quantities output from the receiving unit RX and detects changes in the feature quantities. For example, when a pinch operation such as bending stress is applied to the optical fiber FB, changes occur in each feature quantity of the optical signal transmitted through the optical fiber FB, such as a decrease in the received light level, an increase in the dispersion of the constellation, and an increase in the bit error rate before error correction. Note that a "pinch operation" refers to, for example, an operation of pinching and bending the optical fiber FB with a human finger. A pinch operation is an example of a physical stimulus.

[0025] The signal change detection unit 1 detects that a pinch operation such as bending stress has been applied to the target optical fiber FB when a change occurs in the feature amount output from the receiving unit RX.

[0026] Here, if the bit error rate after error correction is error-free, even if a pinch operation such as a moderate bending stress is applied to the optical fiber FB, there will be no effect on the communication through this optical fiber FB. In other words, by applying a moderate pinch operation to the optical fiber FB, it is possible to intentionally change the above-mentioned characteristic amount without affecting the communication through the optical fiber FB.

[0027] When the signal change detection unit 1 detects a change in a feature amount in an optical signal received by the receiver RX, it outputs the ID of the receiver RX to the display control unit 3.

[0028] The connection database 2 stores a connection relationship table showing information related to various connections in the receiving unit RX. Fig. 3 is an explanatory diagram showing an example of the connection relationship table stored in the connection database 2. As shown in Fig. 3, the connection relationship table describes information showing the correspondence between the ID of each receiving unit RX, the ID of the transmission device TR (mounted transmission device) on which the receiving unit RX is mounted, the ID of the transmission device TR (opposing transmission device) that communicates with the receiving unit RX, the management IP address of the transmission device TR, and the installation location.

[0029] For example, as shown in Figure 3, receiver RX-1-2 (a receiver with an ID of "RX-1-2") is mounted on transmission device TR-1 (a transmission device with an ID of "TR-1") and faces transmission device TR-2 (a transmission device with an ID of "TR-2"). The management IP address of receiver RX-1-2 is "192.168.1.1", and the installation location is "Venue-1".

[0030] Returning to FIG. 1, the display control unit 3 includes a display 31 for displaying images. The display control unit 3 acquires the ID of the receiving unit RX output from the signal change detection unit 1. For example, in the case of the receiving unit RX-1-3, various information corresponding to this receiving unit RX-1-2 is acquired from the connection relationship table stored in the connection database 2. The display control unit 3 identifies the optical fiber FB to which a physical stimulus has been applied based on the acquired various information, and displays an image (identification information) indicating the identified optical fiber FB on the display 31. That is, the display control unit 3 displays the identification information indicating the optical fiber FB in which a change has occurred in the optical signal. A liquid crystal display, a see-through head-mounted display, or the like can be used as the display 31.

[0031] [Operation of the first embodiment] Next, the operation of the visualization device QA according to the first embodiment will be described with reference to the flowchart shown in FIG.

[0032] When a user wants to find out which transmission device TR a desired optical fiber FB among a plurality of optical fibers FB is connected to, the user applies a pinch operation such as bending stress to the desired optical fiber FB. As a result, a change occurs in the characteristic amount of the optical signal received by the receiver RX connected to the desired optical fiber FB. In step S11, the signal change detector 1 detects the change in the characteristic amount included in the optical signal received by the receiver RX.

[0033] In step S12, the signal change detection unit 1 judges whether or not a change has occurred in the characteristic amount of the optical signal detected by each receiving unit RX. If a change has occurred in the characteristic amount (S12; YES), the process proceeds to step S13, and if not (S12; NO), the process returns to step S11.

[0034] In step S13, the signal change detection unit 1 identifies the receiving unit RX in which the change in the feature amount has occurred, and outputs the ID of the identified receiving unit RX to the display control unit 3.

[0035] In step S14, the display control unit 3 refers to the connection relationship table stored in the connection database 2, acquires the ID of the mounted transmission device in which the identified receiver RX is mounted and the ID of the opposing transmission device, and identifies the optical fiber FB connecting the two. For example, as shown in Fig. 3, when the ID of the receiver RX is "RX-1-2", the ID of the mounted transmission device is "TR-1", the ID of the opposing transmission device is "TR-2", and the optical fiber FB connecting them is identified as FB-2-1.

[0036] In step S15, the display control unit 3 displays a visualized image including information on the identified optical fiber FB on the display 31. FIG. 5 is an explanatory diagram showing an example of the visualized image D1 displayed on the display 31. As shown in FIG. 5, the visualized image D1 displays arrows indicating the transmission devices TR-1, TR-2, and TR-3 and the optical fiber FB connecting the transmission devices. In addition, the identified optical fiber FB-1-2 is highlighted. Specifically, the optical fiber FB-1-2 is displayed with a thicker line than the other optical fibers FB. That is, the optical fiber FB-1-2 to which the user has performed a pinch operation is visualized by being displayed with a thicker line. As a result, the user can easily recognize which transmission device TR the desired optical fiber FB is connected to.

[0037] [Effects of the first embodiment] Thus, the visualization device QA of the first embodiment is a visualization device that visualizes a specific optical fiber from multiple optical fibers FB, and includes a signal change detection unit 1 that detects changes that occur in an optical signal when a physical stimulus is applied to each optical fiber FB, and a display control unit 3 that displays identification information indicating the optical fiber FB in which a change has occurred in the optical signal.

[0038] In the first embodiment, the optical fiber FB to which a pinch operation such as bending stress has been applied by the user is highlighted by a thick line or the like on the visualized image D1 displayed on the display 31.

[0039] Therefore, by simply applying a pinch operation such as bending stress to the optical fiber FB, the user can visually recognize which transmission device TR the optical fiber FB is connected to. As a result, it becomes possible to identify individual optical fibers from a large number of optical fibers with a simple operation.

[0040] That is, the visualization device QA according to this embodiment makes it possible to identify the optical fiber FB without adding a marker to the optical fiber FB. When adding a marker to the optical fiber FB, it is necessary to find the position of the added marker, but in this embodiment, it becomes possible to identify the optical fiber FB from any position on the optical fiber FB.

[0041] [Configuration of the second embodiment] Next, a second embodiment will be described. Fig. 6 is a block diagram showing the configuration of a visualization device QB according to the second embodiment and its peripheral devices. The visualization device QB shown in Fig. 6 differs from the visualization device QA described in Fig. 1 in that it includes a pinch detection unit 5 (stimulation detection unit) and a determination unit 6. The pinch detection unit 5 is connected to a camera (imaging unit). The other components are the same as those in Fig. 1, so the same reference numerals are used and the configuration description is omitted.

[0042] The camera 4 is provided, for example, near the optical fibers FB. The camera 4 captures an image of a state in which a physical stimulus is applied to each optical fiber FB. The camera 4 outputs the captured image to the pinch detection unit 5.

[0043] The pinch detection unit 5 detects that a physical stimulus such as a pinch operation has been applied to the optical fiber FB from the image captured by the camera 4. The camera 4 can be mounted on, for example, a see-through head-mounted display.

[0044] The determination unit 6 acquires information output from the signal change detection unit 1 and information output from the pinch detection unit 5. The information output from the signal change detection unit 1 includes the ID of the receiving unit RX where a change has occurred in the optical signal. The information output from the pinch detection unit 5 includes information indicating that a pinch operation has been applied to one of the multiple optical fibers FB.

[0045] The determination unit 6 performs control to output the ID of the receiver RX to the display control unit 3 when the ID of the receiver RX in which a change has occurred in the optical signal is input and a pinch operation is applied to the optical fiber FB.

[0046] [Operation of the second embodiment] Next, the operation of the visualization device QB according to the second embodiment will be described with reference to the flowchart shown in FIG.

[0047] In step S31, the signal change detection unit 1 detects a change in a feature amount contained in an optical signal received by the receiver RX.

[0048] In step S32, the signal change detection unit 1 judges whether or not a change has occurred in the characteristic amount of the optical signal detected by each receiving unit RX. If a change has occurred in the characteristic amount (S32; YES), the process proceeds to step S33, and if not (S32; NO), the process returns to step S31.

[0049] In step S33, the signal change detection unit 1 identifies the receiving unit RX in which the change in the feature amount has occurred, and outputs the ID of the identified receiving unit RX to the determination unit 6.

[0050] In step S34, the pinch detection unit 5 acquires an image of the optical fiber FB captured by the camera 4.

[0051] In step S35, the pinch detection unit 5 refers to the image of the optical fiber FB and determines whether or not a pinch operation is detected. If a pinch operation is detected (S35; YES), the process proceeds to step S36, and if not (S35; NO), the process returns to step S31.

[0052] In step S36, the determination unit 6 determines that a pinch operation has been applied to the optical fiber FB connected to the receiver RX in which a change has occurred in the characteristic amount of the optical signal. The determination unit 6 outputs the ID of this receiver RX to the display control unit 3.

[0053] The display control unit 3 refers to the connection relationship table stored in the connection database 2, acquires the ID of the mounted transmission device in which the identified receiver RX is mounted and the ID of the opposing transmission device, and identifies the optical fiber FB connecting the two. For example, as shown in Fig. 3, when the ID of the receiver RX is "RX-1-2", the ID of the mounted transmission device is "TR-1", the ID of the opposing transmission device is "TR-2", and the optical fiber FB connecting them is identified as FB-2-1.

[0054] In step S37, the display control unit 3 displays on the display 31 an image showing a state in which a pinch operation is being applied to the optical fiber FB. Specifically, as shown in Fig. 8, a visualized image D2 showing the connection state of the optical fiber FB is superimposed on the transparent head mounted display while the finger of the person P1 and the optical fiber FB are realistically brought into view through a transparent head mounted display such as Hololens. That is, the display control unit 3 superimposes and displays the identification information on either one of the real image in which a physical stimulus is applied to the optical fiber and the image captured by the camera 4 (imaging unit) showing the state in which a physical stimulus is applied to the optical fiber.

[0055] In step S38, the display control unit 3 displays an image showing the connection state of the identified optical fiber FB superimposed on the visualized image D2. That is, the display control unit 3 displays identification information showing the optical fiber FB in which a change has occurred in the optical signal. Specifically, as shown in FIG. 8, an image showing that the optical fiber FB is connected from the receiving unit RX of the transmission device TR-1, the management IP address "192.168.1.1", and the installation location "Venue-1" to the receiving unit RX of the transmission device TR-2, the management IP address "192.168.1.2", and the installation location "Venue-2" is superimposed on the visualized image D2. That is, the optical fiber FB on which the user has performed the pinch operation is visualized. As a result, the user can easily recognize the optical fiber FB on which the user has performed the pinch operation.

[0056] [Effects of the second embodiment] In this way, in the visualization device QB of the second embodiment, when a user performs a pinch operation on the optical fiber FB, the receiver RX in which a change has occurred in the characteristic of the optical signal is identified, and the optical fiber FB connected to this receiver RX is further identified.

[0057] Therefore, the robustness when detecting the optical fiber FB can be improved. That is, when the optical fiber FB is specified by detecting only the change in the characteristic amount of the optical signal, there is a possibility that a false detection occurs when a change occurs in the optical signal due to other factors. In this embodiment, the condition is that a pinch operation is detected, so that the occurrence of such a false detection can be avoided.

[0058] [Configuration of the third embodiment] Next, a third embodiment will be described. Fig. 9 is a block diagram showing the configuration of a visualization device QC and its peripheral devices according to the third embodiment. Fig. 10 is a schematic configuration diagram of a network system showing the connection of a transmission device TR equipped with a visualization device QC.

[0059] 10, video sending terminals SD-1-1 and SD-1-2 are connected to a transmission device TR-1. The video sending terminal SD is a terminal that sends a video flow from the transmission device TR-1 to another transmission device TR.

[0060] Video receiving terminals RV-2-1 and RV-2-2 are connected to the transmission device TR-2. Video receiving terminal RV-3-1 is connected to the transmission device TR-3. The video receiving terminal RV is a terminal that receives the video flow transmitted from the video transmitting terminal SD.

[0061] The visualization device QC shown in Fig. 9 differs from the visualization device QB shown in Fig. 5 in that it includes a video flow database 7. The other components are the same as those in Fig. 5, so they are denoted by the same reference numerals and the configuration description will be omitted.

[0062] The video flow database 7 stores a video flow table showing the relationship between the ID of the video receiving terminal RV, the ID of the receiving transmission device TR to which the video receiving terminal RV is connected, the ID of the video transmitting terminal SD, the ID of the transmitting transmission device TR to which the video transmitting terminal SD is connected, the destination IP address of the video flow, and thumbnails, as shown in FIG. 11, for example.

[0063] As the video flow, "SMPTE ST 2110" can be used. The video flow database 7 can be created by acquiring information from the video sending terminal SD and the video receiving terminal RV using "Networked Media Open Specification (NMOS)".

[0064] [Operation of the third embodiment] Next, the operation of the visualization device QC according to the third embodiment will be described with reference to the flowchart shown in Fig. 12. Note that the processing of steps S31 to S36 shown in Fig. 12 is the same as the processing of steps S31 to S36 shown in Fig. 7, and therefore the description will be omitted. Below, the processing of steps S361 to S363 shown in Fig. 12 will be described.

[0065] When the optical fiber FB connected to the receiving unit RX whose features have changed is identified in the processing of step S36, in step S361, the display control unit 3 refers to the video flow table stored in the video flow database 7 to identify the video flow entry.

[0066] Specifically, the display control unit 3 refers to the connection relationship table (see FIG. 3) stored in the connection database 2 to obtain a combination of the ID of the receiving transmission device TR and the ID of the transmitting transmission device TR. The display control unit 3 refers to the video flow table shown in FIG. 11 to search for an entry in which the ID of the receiving transmission device TR matches the ID of the transmission device TR to which the video receiving terminal RV is connected, and the ID of the transmitting transmission device TR matches the ID of the transmission device TR to which the video sending terminal SD is connected. When a matching entry is found, information indicating this connection relationship is set as display information. When there are multiple matching entries, multiple display information indicating the connection relationships are set.

[0067] In step S362, the display control unit 3 displays an image showing a state in which a pinch operation is being performed on the optical fiber FB on the display 31. Specifically, as shown in Fig. 13, while the fingers of a person P1 and the optical fiber FB are realistically brought into view through a see-through head-mounted display such as Hololens, a visualized image D3 showing identification information of the video flow flowing from the video transmitting terminal SD to the video receiving terminal RV is superimposed and displayed on the see-through head-mounted display.

[0068] In step S363, the display control unit 3 displays the information of the video sending terminal SD and the video receiving terminal RV indicating the entry of the identified video flow, superimposed on the visualized image D3 shown in FIG.

[0069] Specifically, as shown in FIG. 13, an image showing the connection from the video sending terminal SD-1-1 to the video receiving terminal RV-2-1, the destination IP address of the video flow "172.16.1.100", and a thumbnail are superimposed on the visualized image D3.

[0070] Furthermore, an image showing the connection from the video transmitting terminal SD-1-2 to the video receiving terminal RV-2-2, the destination IP address "239.1.1.1" of the video flow, and a thumbnail are superimposed on the visualized image D3. That is, when the transmission device TR connected to the optical fiber FB where the change in the optical signal has occurred is identified, the display control unit 3 refers to the video flow database 7 to identify the video receiving terminal RV and the video transmitting terminal SD connected to the identified transmission device TR, and displays an image showing the identification information of the video flow flowing from the identified video transmitting terminal SD to the video receiving terminal RV. As a result, the video flow of the optical fiber FB where the user performed the pinch operation is visualized, and the user can easily recognize the video flow of the optical fiber FB where the user performed the pinch operation.

[0071] [Effects of the third embodiment] In this way, in the visualization device QC of the third embodiment, when a user performs a pinch operation on the optical fiber FB, the receiver RX in which a change has occurred in the characteristic of the optical signal is identified, and further the optical fiber FB connected to this receiver RX is identified.

[0072] Therefore, similarly to the second embodiment described above, it is possible to improve the robustness when detecting the optical fiber FB, which makes it possible to avoid the problem of false detection occurring when a change occurs in the optical signal due to other factors.

[0073] In the visualization device QC of the third embodiment, information regarding the video flow transmitted via the optical fiber FB is superimposed on the visualization image D3, thereby improving the efficiency of operation of the network for video transmission.

[0074] The visualization devices QA, QB, and QC of the present embodiment described above can be, for example, a general-purpose computer system including a CPU (Central Processing Unit, processor) 901, a memory 902, a storage 903 (HDD: Hard Disk Drive, SSD: Solid State Drive), a communication device 904, an input device 905, and an output device 906, as shown in Fig. 14. The memory 902 and the storage 903 are storage devices. In this computer system, the CPU 901 executes a predetermined program loaded on the memory 902, thereby realizing each function of the visualization devices QA, QB, and QC.

[0075] The visualization devices QA, QB, and QC may be implemented in one computer or in multiple computers. Also, the visualization devices QA, QB, and QC may be virtual machines implemented in a computer.

[0076] The programs for visualization devices QA, QB, and QC can be stored on a computer-readable recording medium such as a HDD, SSD, USB (Universal Serial Bus) memory, CD (Compact Disc), or DVD (Digital Versatile Disc), or can be distributed via a network.

[0077] The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the present invention. [Explanation of symbols]
