The DWDM-SFPGE-1550-12 is a 2.5 Gbps eSFP DWDM optical transceiver module operating at 1550.12 nm over single-mode fiber with LC duplex connectors and a 120 km reach.
This module transmits and receives at the ITU-T DWDM channel 1550.12 nm, ensuring precise wavelength alignment for dense wavelength division multiplexing systems.
It supports a maximum link length of 120 km over single-mode fiber under standard G.652 conditions without dispersion compensation.
The transceiver supports a line rate of 2.488 Gbps (2.5 G) for Gigabit Ethernet and SONET/SDH applications.
It features a duplex LC connector, compatible with standard single-mode fiber patch cords for DWDM network deployments.
Yes. It is fully compliant with Multi-Source Agreement (MSA) standards including SFF-8472 for digital diagnostics monitoring.
It works with all major switches, routers, and DWDM multiplexers that support 2.5 G eSFP ports and ITU-T DWDM channels.
The module operates reliably between 0 °C and +70 °C ambient temperature (Commercial grade).
Yes. It provides real-time monitoring of optical output power, input power, temperature, laser bias current, and supply voltage via the I²C interface.
The typical power consumption is <1.0 W, allowing efficient integration into high-density network chassis.
It uses the enhanced small form-factor pluggable (eSFP) package, offering hot-swappable installation in DWDM-capable ports.
Simply power down the port if required, slide the eSFP module into the SFP slot until it clicks, then secure the LC fiber connectors.
