HPE Networking 25G LR SFP28 LC 10km SMF C-Class Transceiver - For Data Networking, Optical Network - 1 X LC 25GBase-LR Network - Optical Fiber25 Gigabit Ethernet - 25GBase-LR - 25 Gbit/s - 10 km Maxim

The HPE Networking 25G LR SFP28 transceiver is a plug-in optical module for HPE network equipment, supporting 25GbE over single-mode fiber with an LC connection for links up to 10 km. It suits organizations connecting network devices across longer fiber runs.

Recommended For

• Network teams linking HPE Aruba switches across buildings or campus closets over existing single-mode fiber, when they need a 25GbE link and the endpoints support this transceiver.
• IT administrators deploying 25GbE uplinks between network switches or server-networking equipment, where the installed fiber is single-mode duplex LC and the link is within the module’s 10 km reach.
• HPE Aruba switch owners choosing an HPE-qualified C-Class optic for a supported SFP28 or SFP56 port; check the compatibility guide for the exact switch model, port, and required software version.
• Network operators extending a 25GbE fiber link beyond a nearby rack or closet, while keeping the connection on single-mode fiber and within 10 km.

Real-World Use Scenarios

• Connecting campus switches in separate buildings: Use a matched pair of these transceivers over an existing single-mode fiber run to carry a 25G uplink between buildings, provided the link budget and distance are within the installation’s limits. This can provide more bandwidth than a 10G uplink without requiring a new fiber route.
• Linking switches in separate data halls: When the halls are connected by single-mode fiber, these optics can support a 25G switch-to-switch connection over distances beyond typical short-reach data-center links. The actual result depends on fiber condition, total link loss, and supported optics at both ends.
• Standardizing links on single-mode fiber across a facility: Network teams that already use single-mode fiber for both short and longer runs may choose LR optics for consistency. A networking-community discussion reports using 25G LR optics inside data centers as well as on longer links; confirm the specific switch supports this HPE transceiver.
• Providing a 25G uplink from a remote network closet to aggregation: Where compatible HPE switches are connected by single-mode fiber, these transceivers can carry traffic from a distant closet back to the campus or facility network. Check the port’s supported transceiver list and the fiber path before deployment.
