Overview - Cisco Compatible 1000Base-BX SFP Bidirectional Transceiver (GLC-BX-D40/U40)

The Cisco compatible small form factor fiber optic transceivers are used in pairs. These transceivers transmit and receive signals on one fiber strand using two wavelengths. These hot pluggable optical transceivers consist of two sections: the transmitter section uses 1490 nm DFB laser/1310 nm Fabry-Perot laser; 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 transceivers use standard simplex LC connectors for fiber cable connection and provide a long transmission distance of up to 40 km. In addition, the transceivers are compliant with SFP Multi-Source Agreement (MSA) Specification and SFF-8472.
