Note
Corning MetroCor fiber is optimized for optical interfaces that transmit at 1550 nm or in the C and L
DWDM windows. This fiber targets interfaces with higher dispersion tolerances than those found in
OC-3 IR/STM-1 SH, OC-12 IR/STM-4 SH, and OC-48 IR/STM-16 SH interface optics. If you are using
Corning MetroCor fiber, OC-3 IR/STM-1 SH, OC-12 IR/STM-4 SH, and OC-48 IR/STM-16 SH
interface optics will become dispersion limited before they will become attenuation limited. In this case,
consider using OC-3 LR/STM-1 LH, OC-12 LR/STM-4 LH, and OC-48 LR/STM-16 LH cards instead
of OC-3 IR/STM-1 SH, OC-12 IR/STM-4 SH, and OC-48 IR/STM-16 SH cards.
Note
With all fiber types, network planners/engineers should review the relative fiber type and optics
specifications to determine attenuation, dispersion, and other characteristics to ensure appropriate
deployment.
Step 1
Plan your fiber connections. Use the same plan for all 1+1 nodes.
Step 2
Align the keyed ridge of the cable connector with the transmit (Tx) connector of a working STM-N card
at one node and plug the other end of the fiber into the receive (Rx) connector of a working STM-N card
at the adjacent node. The card displays an SF LED if the transmit and receive fibers are mismatched (one
fiber connects a receive port on one card to a receive port on another card, or the same situation with
transmit ports).

Step 3
Repeat Steps
and
for the corresponding protect ports on the two nodes and all other working/protect
port pairs that you want to place in a 1+1 configuration.
Step 4
Return to your originating procedure (NTP).
