Overview

1.25G CWDM SFP optical transceiver is a high-performance, cost-efficient solution designed for long-haul data transmission in Gigabit Ethernet and Fiber Channel networks. Leveraging Coarse Wavelength Division Multiplexing (CWDM) technology, it supports multiple wavelengths (e.g., 1470–1610nm) over a single-mode fiber (SMF), enabling up to 40KM transmission distance. This extended reach makes it ideal for metro networks, telecom backbones, and enterprise applications requiring connectivity between geographically dispersed nodes.

Compliant with SFP MSA and IEEE 802.3 standards, the module ensures seamless integration with industry-standard networking equipment. It features low power consumption, an industrial temperature range (-40°C to 85°C), and digital diagnostics monitoring (DDM/DOM) for real-time performance tracking and fault detection. The hot-swappable LC-interface design simplifies installation and maintenance, while its rugged construction guarantees reliability in harsh environments.

By maximizing fiber capacity through CWDM’s multi-channel capabilities, this transceiver reduces infrastructure costs and supports scalable network expansion. Combining long-distance performance with energy efficiency, it is a future-proof choice for high-density, high-capacity optical communication systems.
