Hi, I'm looking for a solution to connect two switches (QSFP28 ports) using a 60km dark fibre. Anyone tried or have any idea on how to achieve this?
The solutions I was thinking about are:
1- Using LR optics and using 1310nm EDFA on TX on both ends to boost the signals up for the 60km journey.
2- Using something like this (https://www.sfpcables.com/qsfp-extender-up-to-80km) to use DWDM ZR SFP+ and MUX/DEMUX on the fibre.
3- Any vendor making 80km QSFP28 optics?
TIA
