Whether 100G WDM equipment can use the OTDR to detect fiber cuts

10

If the user has not logged in to the device, check whether the line OTDR breakpoint detection function is enabled for the 100G systems of the OSN 9600 and OSN 8800. The OSN 8800 is used as an example here. The OSN 8800 supports the fiber doctor (FD) since V100R009. This function requires the TN12ST2 and TN13FIU boards, and U2000 license, and MDS 6630. The U2000 license supports the control item of this function.

Whether the corresponding fiber on the NMS turns red after a fiber cut occurs on WDM equipment
If logical fiber connections are correct and a fiber cut occurs on WDM equipment, the corresponding fiber on the NMS will turn red.

Method used to determine whether optical fiber connections are correct between a router and a WDM board on the client-side of WDM equipment
Disable the ALS function for the client-side laser of the WDM board and enable the laser to forcibly emit light. If the optical port on the router receives optical signals, the optical fiber in the transmit direction is correctly connected. Stop the router from emitting light. If the WDM board reports an R_LOS alarm, the optical fiber in the receive direction is correctly connected.

Whether a 100G WDM system can use the optical-layer subracks for a 40G non-coherent system
Yes, but this hybrid transmission application needs to be evaluated based on network conditions.
