Product Description

This is a high‑performance SFP‑format multimode fiber transceiver module(2.5g sfp module) delivering stable 2.5 Gbps Ethernet over MMF. Designed for network switches, routers, servers or media converters with SFP slots, this module enables reliable fiber uplinks using 850 nm wavelength and an LC duplex connector. With support for link distances up to 300 meters, it is ideal for building scalable, high‑speed fiber networks in campus environments, data centers, or enterprise LAN backbones. Its compatibility with the 2.5GBASE‑SX standard ensures consistent, standards‑based performance while maintaining interoperability across a variety of network hardware.

Key Features

  • Cost-Effective Performance Boost:​ Perfect for transitioning from 1G to 2.5G networks, maximizing the use of your installed multi-mode fiber infrastructure.
  • Extensive Compatibility:​ Designed to be generically compatible with a broad spectrum of networking hardware, ensuring easy deployment.
  • Real-Time Performance Insights:​ Integrated Digital Diagnostics Monitoring (DOM) provides real-time data on temperature, optical power, and bias current for proactive network management.
  • Reliable Transmission:​ Supports a link length of up to 300 meters on standard multi-mode fiber (OM1/OM2/OM3), offering flexibility in network design.
  • Hot-Swappable & Low Power:​ The SFP form factor allows for easy installation and removal without powering down the equipment, while maintaining low power consumption.
  • RoHS Compliant:​ Manufactured to meet RoHS standards, ensuring environmental safety.

    Bought 10 of these 2.5G SFP modules for our office network upgrade, and they’ve been rock solid for 3 months. The 850nm wavelength works perfectly with our existing MMF cables, reaching 280m without any signal loss. DOM function lets us monitor performance in real time, super convenient for troubleshooting. LC duplex connector fits seamlessly with our switches—plug and play, no configuration hassle. Great value for small to medium business use!
