Overview

1.25G CWDM SFP optical transceiver is a high-power, long-reach solution designed for ultra-long-distance data transmission in Gigabit Ethernet and Fiber Channel networks. Utilizing Coarse Wavelength Division Multiplexing (CWDM) technology, it supports wavelengths from 1470nm to 1610nm over single-mode fiber (SMF), achieving an extended transmission range of up to 80 kilometers. This capability makes it ideal for cross-city metro networks, backbone links, and large-scale enterprise infrastructures requiring connectivity between distant locations.

Compliant with SFP MSA and IEEE 802.3 standards, the module ensures seamless compatibility with existing network equipment. It features advanced laser technology for enhanced signal integrity, low power consumption, and an industrial temperature range (-40°C to 85°C) for reliable operation in harsh environments. Integrated digital diagnostics monitoring (DDM/DOM) enables real-time performance tracking and proactive maintenance.

With a hot-swappable LC interface, the transceiver simplifies deployment and upgrades while maximizing fiber utilization through CWDM’s multi-channel efficiency. Its robust design and extended reach reduce the need for signal repeaters, lowering infrastructure costs and complexity. Combining high performance with scalability, this transceiver is a cost-effective, future-proof solution for expanding high-capacity optical networks over ultra-long distances.
