Whether you’re refreshing an aging 10G fabric, consolidating data-center space, or extending your enterprise backplane, this transceiver delivers the speed, compatibility, and resilience your applications demand.
- High-speed 25GBASE-SR performance: The transceiver supports 25 Gbps line rate over short-reach multimode fiber, enabling rapid data replication, real-time analytics, and high-density server-to-switch uplinks. By delivering more data per clock cycle, it reduces network bottlenecks and accelerates critical workloads, helping to shrink batch windows for backups, virtualization, and data-intensive applications. The solution is ideal for modern data centers seeking to consolidate uplinks, optimize rack density, and future-proof infrastructure as workloads grow.
- Reliable multimode fiber compatibility: Optimized for 850 nm MMF links, including common OM3 and OM4 cabling. This compatibility enables cost-effective upgrades by leveraging existing fiber plants, minimizing additional cabling or re-cabling. Whether you’re upgrading a campus core, a top-of-rack (ToR) switch, or a blade-server backplane, the 25GBASE-SR transceiver helps you maximize the value of current fiber while delivering next-generation bandwidth.
- Compact, hot-pluggable SFP28 form factor: The SFP28 footprint plugs into standard 25G-capable SFP28 slots in switches, routers, and servers, delivering a concise, low-profile upgrade path. Its hot-plug design means you can replace or upgrade modules with minimal disruption, supporting rapid scale-out in dense data-center racks and edge deployments without large downtime windows.
- Low-power, energy-efficient design: Engineered to balance high performance with energy efficiency, the transceiver minimizes power consumption in busy environments. This helps reduce cooling requirements in dense racks and can contribute to lower total cost of ownership (TCO) while sustaining peak throughput for demanding workloads.
- Enhanced reliability and interoperability: Built to HP’s rigorous compatibility standards, the C-series transceiver delivers dependable operation with HP networking platforms and a broad range of third-party devices that support 25GBASE-SR and SFP28. This interoperability reduces integration risk, simplifies procurement, and supports mixed-vendor deployments common in modern data centers and enterprise networks.

How to install HPE C-series 25GBASE-SR SFP Transceiver
- Power down or place the target device in maintenance mode if required by your network policy, then prepare the SFP28 slot for replacement or upgrade.
- Handle the transceiver by the edges and align the LC duplex connector with the corresponding fiber optic cable. Confirm fiber cleanliness; use clean and proper termination to avoid signal loss or contamination.
- Gently insert the SFP28 transceiver into the available SFP28 slot until it clicks or seats securely. Do not force the module; ensure full engagement with the host interface.
- Connect a clean LC duplex MMF fiber cable to the transceiver, ensuring transmit and receive ends are correctly paired with the corresponding devices. Verify there are no sharp bends or excessive cable slack that could degrade signal integrity.
- Power up the device (or re-enable the interface) and check the link status in the management console. Confirm the port negotiates to 25 Gbps and monitor the channel for stability and error-free operation. Apply any required firmware updates or interoperability settings as recommended by the device vendor.
