How to Breakout 40G Interface in Cisco NCS 5500

The first time project Cisco NCS 5500 that I received, there is a line card 24H1F (24 ports 100G and 12 ports 40G), with 40G port we can breakout into 4 x 10G pieces.

The default of 24H12F line card is 40G, but can support 100G if license is enabled. When it comes up, the interfaces are forty and hundred gigs.

To see more about NCS line cards, you can read NCS 5500 white paper  documentation and also can be searched in ciscolive.com.

To enable breakout in 40G, hereby the command:

NCS5500#config
NCS5500(config)#interface forty 0/0/0/0
NCS5500(config-if)#no shutdown
NCS5500(config-if)#exit
NCS5500(config)#controller optics 0/0/0/0
NCS5500(config-optics)#breakout 4x10
NCS5500(config-optics)#commit

The interface forty 0/0/0/0 will be change to Ten0/0/0/0/0 – 3.

To see the optical power level, use this command.

Now, how about physical cable? The cisco guys, give this spec:

I found in fs.com [1], they have this type cable spec (I use transceiver LR and cable breakout single mode) and i bought from fs.com and it works.

I tried to use transceiver 40G SR and connect with multimode breakout cable and it does not work 🙂

Now, I am still waiting for MM cable breakout sent by fs.com to use 40G SR and multimode breakout cable.
