If your looking for a L1 DWDM to drop at the site then ekinops has a
10x10 100G that can drop individual 10Gs at a site. I haven't seen any
deployments for mobile carriers, but I have been told they have.
Most I have done to this point has been 100G rings using MPLS/EVPN.
Hardware is typically using Juniper ACX 710, Nokia 7250 IXR-E, or Cisco
NCS 540. These are using 40 or 80K bidi optics, but in some instances
PAM4 and hopefully soon single channel dwdm modules that don't require
outside amplification. I have not found any that you can really use a
true passive system yet, but hopefully will be testing some soon. I have
deployed a couple using 1310/1550 splitters and ran DWDM on top of a
1310 100G channel using 40/80K sfp28s.

I'm looking for referrals to what you've worked with regarding mobile
backhaul services.
We've poked around at a few vendors and it seems like it's common to
have products on either side of what I'm looking for. It appears
common to offer:
1) Just a basic 10x 10G -> 1x 100G muxponder. It seems silly to have a
rack full of muxponders at the CO.
2) Complicated any color to any color ROADM and 25g -> 400G
aggregation DWDM systems that don't go down to the speeds the mobile
operator would want.
It doesn't seem like people have something that offers 1x or 2x 10G
with 2x 100G for east\west routing in a hardened, small form factor.
Awesome if those 100G were tunable, so I could plumb them into a
passive wave system.
