Re: booster to gain distance above 60km

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

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?
