DLP-A44 Install Fiber-Optic Cables for BLSR Configurations
Note
To avoid error, connect fiber-optic cable so that the farthest slot to the right represents the east port, and
the farthest slot to the left represents the west port. Fiber connected to an east port at one node must plug
into the west port on an adjacent node.
Caution
Do not provision the BLSR east and west ports on the same OC-N card.
Step 1
Plan your fiber connections. Use the same plan for all BLSR nodes.
Step 2
Plug the fiber into the Tx connector of an OC-N card at one node and plug the other end into the Rx
connector of an OC-N card at the adjacent node. The card displays an SF LED if the transmit and receive
fibers are mismatched.
Note
Do not mix working and protect card connections when connecting a four-fiber BLSR. The
BLSR does not function if working and protect cards are interconnected. See
for an example of correct four-fiber BLSR cabling.
Step 3
until you have configured the ring.
