> Have you happened to have played with optical version of such cables?
I have some samples of the optics and fibres here, but I haven't played with them yet. It'd be 40GBASE-SR4 (MTP connector) into four 10GBASE-SR LC connectors. We're actually using this for MeerKAT deployment on our antennas for ADC data. I see it as very low risk, and I don't see any logical difference between the copper and fibre implementations. Once you've got the LC breakout (short 1m cable), you can couple it onto a longer fibre at 10Gbps and move across floors or whatever. That can all be done within the rack, using standard fibre patch panels. Jason
