Product Specifications

The 10Gbps 1550nm SFP+ Optical Transceiver is a high-performance module designed for long-distance data communication over single-mode fiber (SMF) up to 40 kilometers. This transceiver is housed in an SFP+ form factor with an LC connector and integrates a 1550nm DFB laser and a PIN photodetector for superior performance. With a data rate of up to 10.3125Gbps, it is an excellent solution for applications such as Ethernet and Fiber Channel networks. The module complies with SFF-8472 and IEC-60825 laser safety standards, ensuring both compatibility and safety.

Operating on a single +3.3V power supply, the transceiver is energy-efficient, with power dissipation below 1W. It is designed to function reliably across an operating temperature range of -5°C to +70°C, making it suitable for a variety of commercial networking environments. Its advanced features include low EMI and excellent ESD protection, ensuring robust operation in high-performance applications.

The optical characteristics of the transceiver are optimized for clarity and reliability. The transmitter operates at a center wavelength of 1530nm to 1550nm, with an average output power ranging from +1dBm to +4dBm. The extinction ratio is maintained at a minimum of 3.5dB, and the receiver sensitivity is rated at -15dBm, with an input wavelength range of 1270nm to 1610nm. Additionally, the transceiver supports key functionalities such as Loss of Signal (LOS) detection for enhanced link monitoring and diagnostics.

Electrically, the module is designed for seamless integration with host systems. It features a differential impedance of 100Ω and supports input swing differentials from 180mV to 700mV. Advanced diagnostic capabilities, including real-time monitoring of temperature, voltage, bias current, and optical power levels, ensure the module operates efficiently within defined parameters. The diagnostic monitoring interface adheres to SFF-8472 standards, providing users with critical data for optimal network performance.

In summary, the 10Gbps 1550nm SFP+ Optical Transceiver is a reliable, high-performance solution for medium-range networking applications. Its combination of robust optical and electrical specifications, coupled with compliance to industry standards, makes it a valuable component in modern data communication infrastructures.

This SFP+ transceiver operates at 10.3125 Gbps and is optimized for 40 km transmission on standard single-mode fiber. It uses a 1550 nm DFB laser without TEC and a PIN photodetector. The module provides <1 W power dissipation and supports a commercial operating case temperature range of −5 °C to +70 °C. Designed with LVPECL-compatible I/O, low EMI, and strong ESD protection, it is fully compliant with SFF-8472 digital diagnostics, RoHS, and IEC 60825 Class 1 laser safety.
