SFP28 Transceiver Module HPE 25GB SR 100m

The HPE 25Gb SFP28 Transceiver delivers 25 Gb/s short-range optical connectivity for data center and enterprise network links up to 100 m. With an LC duplex connector for multimode fiber, this compact module follows the SR specification and fits SFP28 ports to provide higher bandwidth while minimizing cabling and port requirements.

Advantages

This SFP28 transceiver increases bandwidth 2.5× compared with 10GbE, enabling higher throughput with fewer cables and connection ports. It supports connections up to 100 m over multimode fiber, has a low form factor compatible with SFP28 interfaces, and is constructed in aluminium for durability. Power dissipation is allowed up to 3.5 W, making it suitable for dense deployments in data center interconnects.

Suitable for

• Data center switch-to-switch and server-to-switch links
• High-density aggregation and spine-leaf topologies
• Enterprise campus backbone upgrades from 10GbE to 25GbE

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on your switch or server until it latches. Attach a multimode LC duplex fiber cable to the LC connector on the module and route the cable to the corresponding port on the remote device. Ensure both ends use the same SR multimode fiber type and that transceiver firmware and switch port settings support 25Gb/s operation. Monitor link status on the host device to confirm proper negotiation and traffic flow.

Recommendations

Use multimode OM3/OM4 fiber for reliable 25Gb/s links up to 100 m, maintain proper ESD precautions when handling the transceiver, and verify compatibility with your switch vendor using the MPN (845398-B21) or EAN (0190017016559) before deployment.
