Hi
The easy way to get 63 km is to use a SFP+ module that is rated for 63 km.
Fiberstore has 60 km BIDI SFP+ for USD 325 and 80 km BIDI for USD 425.
If you want to use a booster you would need DWDM modules instead. And you
have to add in the DWDM splitter and two boosters. For each end of the link
it would be USD 435 for the SFP+ module, USD 174 for the BIDI DWDM splitter
in a rack chassis and USD 1300 for a 13 dBm output booster.
So - forget about the booster and just get the 80 km BIDI modules.
Regards,
Baldur
