The 25Gbps SFP28 ER Transceiver is a high-performance optical module designed for long-distance data transmission over single-mode fiber (SMF) up to 40 kilometers. Featuring a 1310nm DML laser and an APD receiver, this transceiver supports a data rate of 25.78Gbps, making it suitable for applications such as 25GE BASE-ER Ethernet and CPRI Option 10/eCPRI. The module complies with SFP28 MSA, SFF-8431, and IEEE 802.3cc standards, ensuring compatibility and reliability in modern networking environments.
Operating on a single +3.3V power supply with power consumption under 1.5W, the transceiver offers energy efficiency. It is available in two configurations: commercial (0°C to +70°C) and industrial (-40°C to +85°C), ensuring reliable performance across diverse operating conditions. The hot-pluggable 20-pin connector and LC single connector design make installation and maintenance straightforward. The module also complies with RoHS standards for environmentally friendly operation.
Optically, the transmitter provides an output power of 0dBm to 6dBm and features a side-mode suppression ratio (SMSR) of 30dB, ensuring robust signal integrity. The receiver operates across a wavelength range of 1260nm to 1360nm, with a sensitivity of -19dBm and a maximum input power of -5dBm. The receiver also includes Loss of Signal (LOS) detection for enhanced diagnostic capabilities.
Electrically, the transceiver supports a differential input impedance of 100Ω and offers a single-ended data input swing of 90mVp-p to 450mVp-p. Advanced diagnostic monitoring allows real-time access to parameters such as temperature, voltage, bias current, transmitted optical power, and received optical power. Alarm and warning flags notify users of deviations from factory-set performance thresholds, ensuring reliable operation.
In summary, the 25Gbps SFP28 ER Transceiver is an efficient and reliable solution for high-speed, long-distance optical communication. Its compliance with international standards, advanced diagnostic capabilities, and robust design make it a valuable component in modern telecommunications and data networking infrastructures.
This hot-pluggable transceiver supports data rates up to 25.78 Gbps and complies with IEEE 802.3cc 25GBASE-ER, SFP28 MSA, SFF-8431, SFF-8432, and SFF-8472 standards. It operates over single-mode fiber with a simplex LC connector, providing up to 40 km reach. The module features an internal CDR for both transmitter and receiver chains, a DML transmitter, and an APD/TIA receiver for high sensitivity. Power consumption is <1.5 W on a single 3.3 V supply, with commercial (0 °C to +70 °C) and industrial (−40 °C to +85 °C) temperature options. Integrated DDMI enables real-time monitoring of temperature, bias current, optical power, and supply voltage.
