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

[Andrew Miehs]

Was looking at this a while ago - but haven't had a chance to try any of it
- no one has bought me any 40G kit yet...

>From Cisco - for Multimode - Cisco QSFP-40G-SR4 - This terminates on a
MPO-12 plug which you can connect to 4x 10G SR

Unfortunately Cisco doesn't make a single mode version - but I found -
these from Arista - don't know if they work though - QSFP-40G-PLR4
and QSFP-40G-PLRL4

Good luck, and if you do get to try it out - please keep us informed.

Regards

Andrew
