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. These SFP moduledatalink upto20kmin9/125umsinglemode fiber.
