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.

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 On 26 March 2015 at 13:07, Rodrigo Augusto <rodrigo@1telecom.com.br> wrote:
Hi folksŠ we have a point and have a 63km between point A to point BŠ. We have a sigle fiber ( only one fiber) and use a fiberstore sfp+ 10GB dibi 1270/1330 module to connect these sites. All attenuation are okŠI don¹t have any trouble on fiber Š. I have received this signal on my sfp+:
Receiver signal average optical power : 0.0026 mW / -25.85 dBm
Does anyone know if have some possible to amplifier this scenario to get more 7db ? Is it possible to put any booster or any way to solve this? I think to use a optical PreAmlifierŠbut I don¹t know if is possible because my scenario have just one fiberŠor, use a ROPA- remote optical pumping amplifier) because I have 63kmŠ Does anyone have some idea?
