ALCATEL 1AB373120004 -Lucent optical transmission and switching platforms (XFP/SFP MSA pluggable) Optical Transmission Module

The ALCATEL 1AB373120004 is a 1000Base-CWDM SFP optical transceiver from the same Alcatel-Lucent 1AB373120xxx CWDM SFP family as the 1AB373120001 and 1AB373120002, used across Alcatel-Lucent optical transmission and access platforms. Like its siblings in the range, it is built to the SFP MSA form factor and operates on a fixed CWDM wavelength channel over single-mode fibre (SMF), terminated with an LC duplex connector, allowing several independent Gigabit Ethernet links to share a single fibre pair via passive CWDM multiplexers. The module includes Digital Diagnostic Monitoring (DDM/DOM), giving real-time visibility of temperature, supply voltage, laser bias current, and optical transmit/receive power for remote link health monitoring. Hot-swappable and MSA-compliant, it is intended as a direct drop-in replacement in Alcatel-Lucent chassis and line cards that call for this exact part number. As with the rest of the CWDM SFP family, the precise ITU CWDM channel and maximum reach are set at manufacture and should be confirmed against the original equipment configuration before ordering if an exact wavelength match is required.
