1.25G CWDM-18 SFP Optical Transceiver Module 1610nm 80km Single Mode Duplex LC Fiber Optical Module

Technical specifications

The 1.25G CWDM-18 SFP Optical Transceiver Module is a high-performance Gigabit optical transceiver designed for CWDM (Coarse Wavelength Division Multiplexing) transmission systems. Operating at CWDM Channel 18 (1610nm) with a 1.25Gbps data rate, it supports transmission distances of up to 80km over Single Mode Fiber (SMF).

Built with a standard hot-pluggable SFP form factor, the module features a Duplex LC optical interface and provides outstanding compatibility with Gigabit Ethernet switches, routers, OLTs, media converters, and CWDM transport equipment.

The module utilizes a 1550/1610nm DFB laser transmitter together with a high-sensitivity APD receiver, ensuring stable long-distance transmission, excellent optical performance, and low power consumption. It fully complies with IEEE 802.3z, SFP MSA, and supports optional Digital Diagnostic Monitoring (DDM/DOM) for real-time monitoring of operating status, including temperature, voltage, TX/RX optical power, and laser bias current.

Designed for telecom operators, ISPs, metro networks, enterprise backbone networks, and data centers, this module delivers reliable performance in demanding fiber optic communication environments.
