Overview

1.25G SFP SX 850nm 550M LC Optical Transceiver is a compact, hot-swappable module designed for Gigabit Ethernet and Fibre Channel applications. 

Operating at an 850nm wavelength over multimode fiber (MMF), it supports data rates up to 1.25Gbps with a transmission distance of up to 550 meters, making it ideal for short-reach connections in data centers, enterprise LANs, and storage area networks (SANs). Compliant with IEEE 802.3z 1000BASE-SX standards and SFP MSA specifications, it ensures seamless interoperability with industry-standard networking equipment. 

Featuring an LC duplex connector, the transceiver delivers reliable performance, low power consumption, and plug-and-play simplicity. Integrated Digital Diagnostics Monitoring (DDM) enables real-time monitoring of temperature, voltage, and optical signal levels for proactive network management. With a commercial temperature range (0°C to 70°C) and robust design, it provides stable operation in diverse environments. This cost-effective, high-performance module is a versatile solution for upgrading or expanding existing fiber infrastructure while maintaining backward compatibility and ease of deployment.
