Description
The 1.25Gbps SFP EX Transceiver is a high-performance, cost-effective optical module designed for long-reach gigabit networks over single-mode fiber (SMF). Operating at 1550nm, it supports data transmission up to 1.25Gbps over distances up to 40 kilometers, making it ideal for Gigabit Ethernet, Fiber Channel, and other optical network applications.
The module integrates a DFB laser transmitter, a PIN photodiode receiver with a trans-impedance amplifier (TIA), and an MCU control unit. Digital Diagnostic Monitoring (DDM) allows real-time access to critical parameters including optical power, temperature, supply voltage, and laser bias current, enabling proactive network maintenance. All modules meet Class I laser safety standards, ensuring safe and reliable operation.
Equipped with a duplex LC connector, hot-pluggable SFP form factor, and a single +3.3V power supply, this transceiver can be easily installed in switches, routers, and server backplanes. Optional extended temperature versions (-20°C to +85°C) allow deployment in industrial or harsh environments.
