ok so I find it hard to explain, so I created a diagram - https://i.imgur.com/lKRPas2.png
has anyone ever broken a QSFP 100G CWDM based optic (using some sort of product) into it's 4 individual waves/channels, then connected that to another CWDM shelf? Not talking about DAC cables that let you breakout 40gb into 4x10gb, but actually running 40G/100G over multiple CWDM channels.
e.g. if you had a CWDM shelf with say 8 channels, and 4 happened to match the 4 waves on the QSFP, could you run 100G over 4 channels whilst still using the 4 remaining CWDM channels (over a single dark fibre pair)?
did some searching, and came across this for 40G - so (at least for 40G) it might possible?
