Optics Controllers
Controllers are represented in the rack/slot/instance/port format (r/s/i/p); for example, 0/3/0/1. Each port has an optics controller that is created on startup.
![]() Note |
You must shut down the optics controller before you perform any of the following tasks:

![]() Note |
When there are dualrate optics on NCS-57C3-MOD-S/-SE-S + NC57-MPA-12L-S, and while configuring lower speed, you may see a few initial link flaps, after that the link stabilizes and no further flaps will be seen. |
CFP2 DCO Optics Support
There are two hardware versions of the CFP DCO optics (A0 and B0). You can identify the version A0 and B0 using a show coherent driver internal location 0/0/CPU0 command and looking at "VID".
A0 = V01
B0 = V02
The CFP2 DCO version A0 optics support the following traffic types:

Support for DP04CFP2-D15 Bidirectional CFP2-DCO Optical Module |
Release 7.8.1 |
In this release, support for DP04CFP2-D15 bidirectional CFP2-DCO optical module is added for NC55-MOD-A-S and NCS-55A2-MOD-S routers with the following MPAs:
The bidirectional CFP2-DCO optical module allows for data transmission and reception in both directions over a single fiber of a network, offering a cost and operationally effective method for expanding the network capacity in fiber-restricted networks. |
The bidirectional CFP2-DCO optical module provides an effective way to increase the network capacity in situations where only single fiber is available. The bidirectional CFP2-DCO optical module enables data transmission and reception in both directions over single fiber of a network. Using dense wavelength division multiplexing (DWDM), the bidirectional CFP2-DCO optics can operate at 100G and 200G speeds through NC55-MPA-2TH-S and NC55-MPA-1TH2H-S MPAs operating in NC55-MOD-A-S and NCS-55A2-MOD-S routers.
The bidirectional CFP2 DCO optics support the following traffic configurations:

Configuring Bidirectional CFP2 DCO Optical Module
This example shows steps to configure a 200G bidirectional CFP2 DCO optical module with Tx channel 1 and Rx channel 3:
RP/0/RP0/CPU0:router(config)#controller optics 0/0/1/0
RP/0/RP0/CPU0:router(config-optics)#port-mode 200G qpsk ofec diff disable
RP/0/RP0/CPU0:router(config-optics)#commit
RP/0/RP0/CPU0:router(config-optics)#dwdm-carrier 50Ghz-grid itu-ch 1
RP/0/RP0/CPU0:router(config-optics)#commit
RP/0/RP0/CPU0:router(config-optics)#exit
RP/0/RP0/CPU0:router(config)#controller optics 0/0/1/1
RP/0/RP0/CPU0:router(config-optics)#port-mode 200G qpsk ofec diff disable
