HPE JL293A Compatible 25GBASE-SR SFP28 850nm 100m DOM Duplex LC/UPC MMF Optical Transceiver Module

The 25Gbps SFP28 SR Transceiver is a high-performance optical module designed for short-range communication over multimode fiber (MMF) with a maximum link length of 70 meters using OM3 fiber and 100 meters using OM4 fiber. It features an 850nm VCSEL transmitter and a GaAs PIN photodiode receiver, providing reliable data transfer at a rate of 25.78Gbps. This module is ideal for applications such as inter-rack connections, high-speed servers, high-performance computing clusters, and SANs. It adheres to SFP28 MSA, SFF-8431, and SFF-8432 standards, ensuring compatibility with modern networking systems.

Operating on a +3.3V power supply, the transceiver consumes less than 1W, making it energy efficient. It supports a commercial temperature range of 0°C to +70°C, with an industrial option available for operation between -40°C and +85°C. The hot-pluggable design with a dual LC interface simplifies integration into existing systems, and its compliance with RoHS underscores an environmentally friendly design.

Optically, the transmitter provides a center wavelength between 840nm and 860nm, with an average optical power ranging from -5dBm to +2.4dBm. The extinction ratio is maintained at 3dB, ensuring reliable signal quality. The receiver operates within the same wavelength range and offers a sensitivity of -10.3dBm, with an overload threshold of +2.4dBm. Additional features, such as Loss of Signal (LOS) functionality, enhance diagnostics and network stability.

The transceiver supports advanced digital diagnostics as defined by SFF-8472, allowing real-time monitoring of parameters such as temperature, voltage, bias current, transmitted power, and received power. Alarms and warning flags provide alerts for deviations from optimal conditions, ensuring proactive maintenance and operational reliability. The two-wire serial interface provides access to these diagnostics, enabling efficient management of network infrastructure.

In summary, the 25Gbps SFP28 SR Transceiver is a reliable and energy-efficient solution for high-speed, short-distance networking. Its advanced features, compliance with industry standards, and robust design make it an essential component for data centers and enterprise networks.

This hot-pluggable module supports 25.78 Gbps operation and complies with IEEE 802.3by 25GBASE-SR, SFP28 MSA, SFF-8431, SFF-8432, and SFF-8472 standards. It operates over multimode fiber using a duplex LC connector, with maximum reach of 70 m on OM3 and 100 m on OM4 fiber. The design incorporates an 850 nm VCSEL laser, PIN/TIA receiver, and internal CDR for both Tx and Rx paths. Power consumption is <1 W on a single 3.3 V supply, with commercial (0 °C to +70 °C) and industrial (−40 °C to +85 °C) versions available. Integrated DDMI allows monitoring of temperature, bias current, optical power, and voltage.
