- step S101 the remote control device 93 switches to a specific optical node 91-1 in the optical fiber network so as to connect the remote control device 93 functioning as an optical node in the communication building and the optical node 91-1. Give instructions. This connects the remote control device 93 and the optical node 91-1.
- the optical switch 122#1 of the optical node 91-1 is connected to the remote control device 93.

- the remote control device 93 acquires the light intensity measured by the optical port monitoring function section 11 through the remote control section 13 of the corresponding optical node.
- port #1-6 and port #5-1 are connected. Therefore, port #1 and port #5 are connected through steps S102 and S103. Further, port #1 is located on the upper loop side. Therefore, if the connection is normal, the test light passes from port #1 to port #5, and the light intensity of the test light is measured by the optical port monitoring function unit 11 of port #1 and port #5. Therefore, the remote control device 93 determines whether the optical switches 122#1 and 122#5 have the optical intensity measured by the optical port monitoring function unit 11 of ports #1 and #5 (normal in S105). The presence or absence of an abnormality is determined, thereby confirming that the switching has been completed normally. In this case, switching of optical node 91-1 is completed.
- the remote control device 93 determines that an abnormality has occurred (abnormal in S105).
- the present disclosure connects the ports within the optical node 91 (S102 and S103) and measures the light intensity in the optical port monitoring function unit 11 (S104 and S105), so that the internal It is possible to determine an abnormality such as failure of connection in the optical cross-connect 12.
- port #1 and port #5 must be isolated. Therefore, to confirm the abnormality, switch to another available port on an alternative route that can be connected to the same route. Note that the following assumes that the same channels such as port #2 and port #6 are free.

- the connection of the optical switch 122#2 of port #2 of the optical node 91-1 is instructed to be switched to port #2 and port #2-6. It also instructs to switch the connection of the optical switch 122#5 of port #5 of the optical node 91-1 to port #5 and port #5-3.
- step S109 test light is transmitted from the test light transmitter 95 to the optical fiber to which the switched optical switch 122#2 is connected.
- the optical node 91-1 is instructed to measure the optical intensity at the optical port monitoring function section 11.
- step S110 the optical port monitoring function unit 11 of the optical node 91-1 measures the optical intensity.
- the optical port monitoring function unit 11 of the optical node 91-1 measures the optical intensity of the test light at ports #2 and #5.
- the remote control device 93 acquires the light intensity measured by the optical port monitoring function section 11 through the remote control section 13 of the corresponding optical node 91-1.
- port #2-6 and port #5-3 are connected. Therefore, port #2 and port #5 are connected through steps S107 and S108. Further, port #2 is located on the upper loop side. Therefore, if it is normal, the test light will pass from port #2 to port #5, and the optical port monitoring function unit 11 of port #2 and port #5 will measure the light intensity of the test light ( Normal in step S110). In this case, the remote control device 93 can confirm that the switching has been completed normally based on the fact that the test light has been detected by the optical port monitoring function unit 11 of port #2 and port #5. Also, based on this result, it is determined that the optical switch 122#1 of port #1 is in failure.
- step S111 the server 94 treats the optical switch 122#1 of port #1, which is determined to be abnormal by the optical node 91-1, as abnormal and manages it so that it will no longer be used. This completes the switching of the optical node 91-1 using the alternative route using ports #2 and #5. It should be noted that the optical switch 122#1 that has been determined to be faulty will be repaired at a possible timing (this will be handled as planned maintenance).
- the remote control device 93 switches the optical fiber used in the corresponding optical node 91-1 from port #2 to port #1 (S108).
- an attempt is made to connect to port #1 as port #6 as an alternative route to port #5 of the optical node 91-1 (S108).
- the remote control device 93 instructs the optical switch 122#1 of the port #1 of the optical node 91-1 to switch the connection to the port #1-3.
- the connection of the optical switch 122#6 of the port #6 of the optical node 91-1 is instructed to be switched to the port #6-1.
- Port #1-3 and port #6-1 are connected.
- port #1 and port #6 are connected.
- test light is transmitted from the test light transmitter 95 from the communication building side to the optical fiber in the optical fiber network to which port #1 of the optical node 91-1 is connected (S109). Subsequently, the optical port monitoring function unit 11 of the optical node 91-1 checks the test light transmitted to port #1 and port #6 (S110).
- test light passes from port #1 to port #6, so the test light is confirmed by the optical port monitoring function unit 11 of port #1 and port #6. In this case, it can be confirmed that the switching has been completed normally. Also, based on this result, it is determined that the optical switch 122#5 of port #5 has failed, and henceforth, the optical switch 122#5 of port #5 will not be used. Note that the corresponding optical switch 122#5 will be repaired as soon as possible (this will be handled as planned maintenance).
- the plurality of optical switches 122 will fail as described below. That is, there is a possibility that both the optical switches of port #5 and port #6 are out of order, there is a possibility that both the optical switches of port #1 and port #2 are out of order, port #1, port #2, port #5, Among the optical switches for port #6, there is a possibility that three optical switches 122 are out of order; furthermore, there is a possibility that all of the optical switches 122 in port #1, port #2, port #5, and port #6 are out of order; is assumed. In this manner, the present disclosure can determine which optical switch 122 may be abnormal among the optical switches 122 used within the optical node 91-1.
- the optical switch 122 is switched to an unused port on the same path one by one, the optical port monitoring function unit 11 measures the light intensity, and the remote control device 93 confirms that the abnormality is detected. Continue switching until no longer possible. However, if there are no unused ports (there is no alternative route in step S106), switching will not be possible. In this case, the remote control device 93 determines that the switching of the corresponding optical node 91-1 has not been completed and that the optical node 91-1 requires repair.
- the optical node 91 be operated with low power consumption. Therefore, as long as there is an alternative route, instead of continuing to change the alternative route, an upper limit may be set on the number of times the alternative route can be changed. In this way, if switching is performed a certain number of times or more and an abnormality is confirmed in multiple optical switches 122 at the same time, the alternative route is not changed and the optical switch 122 of the corresponding optical node 91-1 is , the system will be operated to immediately repair any malfunctions. This has the effect of suppressing the power usage of the optical node 91-1.
- the present disclosure uses the remote control device 93 to notify the communication building of the occurrence of the abnormality in real time when an abnormality occurs such as failure of connection in the optical cross-connect 12 inside the optical node. It can be detected by Further, the present disclosure can use the remote control device 93 to switch a failed port to an adjacent port.
