Does this have to be Ethernet? You could look into line gear with coherent optics. IIRC, they have built-in chromatic dispersion compensation, and depending on the card, would include amplification. On Fri, Sep 24, 2021 at 1:40 PM Randy Carpenter <rcarpen@network1.net> wrote:
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.
