The SFP BIDI transceivers are small form factor pl able module for Gigabit Ethernet 1000BASE-BX and Fiber Channel single fiber applications by using 1310nm/1550nm transmitter and 1550nm/1310nm receiver. It is with the SFP 20-pin connector to allow hot plug capability. The transmitter section uses a multiple quantum well A type/ B type laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated B type/ A type detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. The SFP BIDI transceivers are designed to be compliant with SFF-8472 Multi-source Agreement (MSA).
