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

[Andrew Miehs]

As I said, you should be able to use the cisco qspf-40g-sr4 and an mpo-12 to lc breakout cable which you can then connect to sfp-10g-sr s.

For single mode you would need an alternative supplier for the qsfp who do something similar for lr - like the plr4 from arista - but no idea if it works on a cisco,
