1.12.1 Fiber Cut Detection

Figure 1-21 Linear Network, With No Fiber Cut

1.12.1.1 Scenario A

Scenario A has the following conditions:

• ALS Mode = Auto Restart on OPT-BST (+ OSCM) and OSC-CSM

• Fiber cut on the fiber between the OLA-TX node and the ROADM-RX node

The ALS protocol (refer to the “Network Optical Safety—Automatic Laser Shutdown” section in the

“Network Reference” chapter of the Cisco ONS 15454 DWDM Reference Manual) is activated in the

event of a fiber cut, resulting in the shutdown of optical power on both of the fibers belonging to the

affected span, even if only one of the two fibers is cut.

The final fault condition of the network is shown in Figure 1-22.
