100GbE beyond 40km

Fri Sep 24 20:38:55 UTC 2021

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.

thanks,
