SFP 1.25G 1310nm 20km LC Duplex
SFP Overview:
Small Form FactorPluggable(SFP) transceivers are compatible with the SmallFormFactor Pluggable Multi-Sourcing Agreement (MSA),Thees SFP transceiver consists of five sections: the LDdriver, the limiting amplifier, thedigital diagnostic monitor, the FP laserandthePINphoto-detector.
