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