You may also find that 100G PAM4 could work. There are some vendors that sell the optic, and an outboard EDFA + DCF pizza box.
We are about to deploy these on a couple of dark fibers: https://www.solid-optics.com/product/edfamux-multiplexer-amplifier-dispersio... They have amplified and dispersion compensated 8x100G to be used with PAM4 optics, and a pass-through port to connect existing 1G/10G MUXes to (which can have their own amplification if necessary). They can provide models with different sets of channels of you need that (nice when cascading them with existing 1/10G MUXes). IIRC next year they can also build in a power meter so you can do remote monitoring. If you're interested I can let you know how much we like them in a few months ;) Cheers, Sander
