N93180YC-EX support for FEC in 5m DAC

[mgr]

Hi, 

Does N93180YC-EX support FEC in 25G ports with 5m DAC cables with NX-OS? Cisco optics matrix link shows that this is supported for 3m cable, but no information available for 5m cables.  Does this mean N93180YC-EX does not have support for 5m DAC cables with NX-OS? Has anybody used 5m DAC with this model in your data center? Please help.

Yes, your assumtion is correct.

This is what is mentioned in the data sheet of N93180YC-EX:

The switch has FC-FEC enabled for 25Gbps, and supports upto 3m in DAC connectivity.
