Overview

1.25G SFP EX 1310nm 40KM LC Optical Transceiver is a high-performance, hot-swappable module designed for extended-reach Gigabit Ethernet and fiber optic communication applications. 

Operating at a 1310nm wavelength over single-mode fiber (SMF), it supports data rates up to 1.25Gbps with a transmission distance of up to 40 kilometers, making it ideal for long-haul connections in metro networks, telecom backbones, and cross-campus infrastructure. Compliant with industry standards and SFP MSA specifications, it ensures seamless compatibility with existing networking equipment. Featuring an LC duplex connector, the transceiver delivers reliable signal integrity, low power consumption, and plug-and-play installation. 

Integrated Digital Diagnostics Monitoring (DDM) enables real-time tracking of temperature, voltage, and optical performance for proactive maintenance. Built to operate in a commercial temperature range (0°C to 70°C), it ensures stable performance in diverse environments. This module offers a cost-effective, scalable solution for expanding fiber networks over extended distances while maintaining backward compatibility and ease of integration with legacy systems.
