Product Specifications

The 10Gbps 850nm SFP+ Optical Transceiver is a high-performance module designed for short-distance data communication over multimode fiber (MMF) up to 300 meters. Encased in a compact SFP+ form factor with a duplex LC connector, it integrates an 850nm VCSEL laser and a PIN photodetector for reliable optical transmission. The transceiver supports data rates of up to 10.3125Gbps, making it suitable for applications such as Ethernet and Fiber Channel networks. Compliance with SFF-8472 and IEC-60825 ensures safety and compatibility, while its RoHS certification underscores its environmental responsibility.

The transceiver operates efficiently within a supply voltage range of 3.15V to 3.45V and a commercial temperature range of 0°C to +70°C. It consumes less than 1W of power, offering energy-efficient performance. Designed to minimize electromagnetic interference (EMI) and provide excellent electrostatic discharge (ESD) protection, this module is a dependable choice for high-performance networking environments.

Optically, the transmitter operates at a center wavelength of 850nm, with an average output power ranging from -5dBm to -1dBm and an extinction ratio of 3.0dB. The receiver is optimized for wavelengths centered around 850nm, offering a sensitivity of -11.5dBm and an overload threshold of -3dBm. Diagnostic features such as Loss of Signal (LOS) detection ensure enhanced monitoring and fault detection for stable operations.

Electrically, the module supports a differential impedance of 100Ī©, with input swing differentials ranging from 180mV to 700mV for the transmitter and output swing differentials from 300mV to 800mV for the receiver. Advanced diagnostics adhering to SFF-8472 standards enable real-time monitoring of key parameters such as temperature, voltage, bias current, transmitted optical power, and received optical power. Alarm and warning flags provide alerts for deviations from factory-set operational ranges.

In summary, the 10Gbps 850nm SFP+ Optical Transceiver is a reliable and efficient solution for short-distance networking applications. Its advanced features and compliance with industry standards make it an ideal component for modern data communication infrastructures.

This hot-pluggable SFP+ module operates at 10.3125 Gbps using an 850 nm VCSEL laser and PIN photodiode receiver. It supports up to 300 m over OM3 multimode fiber (2000 MHzĀ·km) and offers interoperability across a wide range of MMF types. Power dissipation is below 1 W, with a single 3.15–3.45 V supply. The unit complies with SFF-8472 digital diagnostics, RoHS, and IEC 60825 Class 1 laser safety.
