This basically comes down to the implementation on how LOS is detected on the RJ45 versus the SFP+ module. In the optical case the LOS can be detected either via the LOS or the LOS of the pin detector,...

Re: MCX312A-XCBT ConnectXR-3 card with Mellanox SFP module 1 Gb Ethernet
This is what we are saying in the copper case (RJ45) when the link goes down the OS will not detect the link lost because the LOS is detected via the LOS pin which is not connected. This is not the...

Re: Omni-Path vs. Mellanox
Hi Serge, Here are the answers:1. it is for copper cables up to 2m in length and fiber optics up to 30m in length. Beyond that we have of course a superset of more capabilities (FEC and LLR) that being...
