Re: booster to gain distance above 60km

[Rodrigo 1telecom <rodrigo () 1telecom com br>]

Already use this bidi sfp+ to 80km from fiberstore... But i can't link two sides... Have -24dbi... Everything alright 
with  fiber... If i using this circuit with this signal i will have many trouble...
I wiil buy a dwdm simplex solution from fiberstore again to use on this curcuit... 
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?
