Overview

1.25G DWDM SFP optical transceiver is a high-density, precision-engineered solution designed for long-distance, high-capacity data transmission in Gigabit Ethernet and Fiber Channel networks. Leveraging Dense Wavelength Division Multiplexing (DWDM) technology, it supports ultra-narrow wavelength spacing (ITU-T grid compliant) over single-mode fiber (SMF), enabling up to 40KM transmission with exceptional signal integrity. Ideal for metro core networks, data center interconnects, and telecom backbone systems, this module maximizes fiber capacity by multiplexing multiple channels onto a single fiber, reducing infrastructure costs and complexity.

Compliant with SFP MSA, IEEE 802.3, and DWDM standards, it ensures seamless integration with industry equipment. The transceiver features low power consumption, industrial temperature range support (-40°C to 85°C), and digital diagnostics monitoring (DDM/DOM) for real-time performance management and fault detection. Its hot-swappable LC interface simplifies deployment and maintenance, while advanced thermal design ensures stability in demanding environments.

Combining DWDM’s spectral efficiency with SFP flexibility, this transceiver delivers a scalable, future-proof solution for expanding network bandwidth and supporting high-speed, long-haul optical communication requirements.
