Description
The 1.25Gbps SFP SX Transceiver is a high-performance, cost-effective optical module designed for short-reach gigabit networks over multimode fiber (MMF). Operating at 850nm, it supports data transmission up to 1.25Gbps over distances up to 550 meters, making it ideal for Gigabit Ethernet, Fiber Channel, and other optical network applications.
The module integrates a VCSEL laser transmitter, a PIN photodiode receiver with a trans-impedance amplifier (TIA), and an MCU control unit. Digital diagnostics monitoring enables real-time access to parameters such as optical power, temperature, and supply voltage. All modules comply with Class I laser safety standards for secure and reliable operation.
With a duplex LC connector, hot-pluggable SFP form factor, and a single +3.3V power supply, the module can be easily integrated into switches, routers, and server backplanes. Extended temperature versions (-20°C to +85°C) are available for deployment in harsh environmental conditions.
