IIRC, the lambda spacing for 100GBASE-LR4 is tig

No, though the lane colors are irrelevant since we only care about the final
output color. Why the lanes can’t be muxed into another output color I’m not
sure, I can only find specs listed for the l

I believe the 40g and 100g optics are already muxing 4 channels within the
transceiver before outputting it to 1310.

QSFPs generally output 4 lanes of traffic. Either 4 channels at 10G or 4
channels at 25G. So unless you find an optic that can do single-channel
OTN at 100G, you’re probably going to have a hard time plugging them into a
DWDM shelf.
