The 25Gbps SFP28 LR Transceiver is a high-performance module designed for long-distance data communication over single-mode fiber (SMF) up to 10 kilometers. It features a 1310nm DML laser transmitter and a PIN/TIA receiver, supporting a data rate of 25.78Gbps. This module is compliant with the SFP28 MSA, SFF-8472, and IEEE 802.3cc standards, making it suitable for applications such as data center backbones, Ethernet switches, high-speed servers, and SAN networks.
Operating on a single +3.3V power supply with power consumption under 1.2W, the transceiver ensures energy-efficient performance. It is available in both commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges, making it versatile for various environments. The hot-pluggable design with a duplex LC connector enables seamless integration into networking systems, while RoHS compliance emphasizes its environmentally friendly design.
Optical performance includes a center wavelength range of 1290nm to 1330nm for the transmitter, with an average optical power output of -7dBm to +2dBm. The extinction ratio is maintained at 3.5dB, ensuring robust signal clarity. The receiver supports wavelengths from 1260nm to 1360nm, with a sensitivity of -12dBm and an overload threshold of +2dBm. The transceiver includes Loss of Signal (LOS) detection to enhance diagnostic capabilities.
Electrically, the module supports a differential impedance of 100Ω and input/output swing differentials from 90mV to 450mV. Advanced features like Transmit Disable (TX_DISABLE) and Fault Indicators allow precise control and fault management. Digital diagnostics provide real-time monitoring of parameters such as temperature, voltage, bias current, and optical power, enabling proactive maintenance and reliability.
In summary, the 25Gbps SFP28 LR Transceiver is a reliable and energy-efficient solution for high-speed optical communication over medium distances. Its compliance with industry standards, advanced diagnostic capabilities, and robust design make it an essential component for modern telecommunications and data center infrastructures.
This hot-pluggable transceiver supports data rates up to 25.78 Gbps and complies with IEEE 802.3cc 25GBASE-LR, SFP28 MSA, SFF-8431, SFF-8432, and SFF-8472 standards. It operates up to 10 km over 9/125 µm SMF using a duplex LC connector. The design integrates a 1310 nm DML transmitter, PIN/TIA receiver, and internal CDR on both Tx and Rx paths for signal integrity. Power consumption is <1.2 W on a single 3.3 V supply, with commercial (0 °C to +70 °C) and industrial (−40 °C to +85 °C) operating options. Integrated DDMI provides real-time monitoring of temperature, voltage, bias, Tx, and Rx optical power.
