Re: Cisco CRS with 100Gb line card

said by Smokeshow:

Correct me if I am wrong, but those look like SC connectors on that fiber... Does that thing really only require 2 fibers to push 100G? I was under the impression that 100G used a total of 20 fibers for 10x 10G channels and typically used 2 ribbons of fiber with MTP connectors.

Back when 100G came out that was true, but it hasn't been the case with the advent of WDM and DWDM technology (pioneered I believe, with 40G ethernet).

That's still true for "SR" (multimode fiber), but who's going to do 100G on MM???

(It's more likely to use the SR optic to make a single 100G interface 10x10G interfaces.)
