Thanks for sharing.  First time I saw 10G BiDi optics at 80 km.  I =
needed them for an application a few months ago and had to take a new =
approach when I only could find 60 km ones.

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
