[c-nsp] 40G QSFP to 4*10G SFP+ Breakout Optical Cable

[David Paul Zimmerman]

This may be a weird tangent to your question, but if you're running on a Nexus 6004 (maybe other platforms too, but definitely the 6004) and don't mind wasting a whole 40GE QSFP port to service a 10GE drop (say you're way overprovisioned on 40GE capacity and can do that), you should check out Cisco's CVR-QSFP-SFP10G QSFP to SFP+ converter.

Hi all

 I have been searching for 40G to 4*10G cables (not DAC/Twinax but optical ones). 
 Did you ever use such cables ? is it reliable ?
 I did not find any monomode ones, I guess this is not existing... any idea why (strength of signal ?) ?

Thanks & best regards
Gilles
