Hi,

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-dispersion-compensation-dwdm-mux-edfa/

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
