Look into EDFA amplifier systems. They work over a range of bands and are pretty affordable. They can carry regular 1310nm as well as C-Band. Although if you are carrying C-band you may have to compensate for chromatic dispersion. Happy to help, I love this stuff!

How is everyone accomplishing 100GbE at farther than 40km distances?
Juniper is saying it can't be done with anything they offer, except for a single CFP-based line card that is EOL.
There are QSFP "ZR" modules from third parties, but I am hesitant to try those without there being an equivalent official part.
The application is an ISP upgrading from Nx10G, where one of their fiber paths is ~35km and the other is ~60km.
