Already use this bidi sfp+ to 80km from fiberstore... But i can't link two s=
ides... Have -24dbi... Everything alright with fiber... If i using this cir=
cuit with this signal i will have many trouble...
I wiil buy a dwdm simplex solution from fiberstore again to use on this curc=
uit...=20
What booster and preamplifier i have to use on it?!
I will buy a 8channel simplex ... C21/c51, c22/c52 etc.... Do you know what a=
booster and an amplifier i have to buy?

Fiberstore has 60 km BIDI SFP+ for USD 325 and 80 km BIDI for USD 425.
