Re: SFP module for 100km

said by spectrumhead:

We have tried now HP SFP J4860C but it didint link up. Anyone ?

By any chance do you have a light meter, the reason I ask is you might have an open fiber or two and not an SFP problem and since you have working SFP's you could shoot light down the fiber and measure it at the other end and compare what you are transmitting versus what you are receiving and if it is about 32 down you know the fibers are good, but if you are receiving nothing then your chasing the wrong dog for now going the SFP route.
