The DWDM-SFPGE-1556-55 is an eSFP 2.5 Gb/s DWDM optical transceiver module operating at 1556.55 nm for up to 120 km single-mode links with an LC interface.
This module supports up to 120 km over ITU-T G.652 single-mode fiber without requiring inline amplification.
It is designed for ITU-T G.652 standard single-mode fiber, ensuring minimal dispersion and optimal DWDM performance.
It operates at the 1556.55 nm DWDM wavelength, corresponding to ITU-T grid channel 33, for dense wavelength division multiplexing.
The module supports a data rate of 2.5 Gb/s, ideal for Gigabit Ethernet and SONET/SDH applications.
This product is an enhanced SFP (eSFP) transceiver, fully compliant with the SFP Multi-Source Agreement (MSA).
Yes, it offers Digital Diagnostic Monitoring (DDM/DOM) for real-time monitoring of temperature, voltage, bias current, and optical power.
Yes, the module is hot-pluggable, allowing insertion and removal without powering down the host system.
The module provides a link budget of approximately 23 dB, accommodating up to 120 km transmission at standard fiber attenuation.
It operates reliably between 0 °C and 70 °C (standard commercial range) and up to –40 °C to 85 °C in industrial-grade versions.
Ideal for DWDM metro, long-haul networks, data center interconnects, and high-capacity backbone aggregation.
Insert the transceiver into a compatible SFP slot, ensure proper fiber polarity on the LC connectors, then verify link status via the host interface.
Yes, it adheres to the SFP MSA, ensuring electrical, mechanical, and optical compatibility across vendors.
Use a recommended fiber-optic cleaning tool and isopropyl alcohol to gently remove dust and contaminants before each connection.
