Overview

1.25G DWDM SFP optical transceiver is a high-performance, ultra-long-haul solution designed for mission-critical data transmission in Gigabit Ethernet and Fiber Channel networks. Leveraging Dense Wavelength Division Multiplexing (DWDM) technology, it operates on ITU-T grid-compliant wavelengths with ultra-narrow channel spacing, enabling up to 80KM transmission over single-mode fiber (SMF). This extended reach makes it ideal for inter-city metro networks, cross-regional data center interconnects (DCI), and high-capacity telecom backbone systems requiring robust, long-distance connectivity.

Compliant with SFP MSA, IEEE 802.3, and DWDM standards, the module ensures seamless integration with existing infrastructure while maximizing fiber capacity through multi-channel multiplexing. It features low power consumption, industrial temperature range support (-40°C to 85°C), and digital diagnostics monitoring (DDM/DOM) for real-time performance tracking and proactive maintenance. The hot-swappable LC interface simplifies deployment, and its advanced error correction and thermal design ensure stable operation in harsh environments.

By combining DWDM’s spectral efficiency with extended reach, this transceiver reduces reliance on repeaters, lowers operational costs, and supports scalable network expansion. Its future-proof architecture makes it a cost-effective choice for high-density, high-bandwidth applications demanding reliable, long-haul optical communication.
