Intel Ethernet SFP28 Optics 10GbE 25GbE SFP28 Transceiver Module

The Intel E25GSFP28SR is an SFP28 optical transceiver built for network teams that want faster links without a complete infrastructure overhaul. It supports both 25-gigabit and 10-gigabit Ethernet speeds, so you can move to higher bandwidth when you are ready while staying compatible with existing 10G equipment. Simply plug the module into an Intel Ethernet adapter such as the XXV710 series and the connection is live.

This model is designed for short-range links up to 328 feet, making it a practical choice for rack-to-rack or row-to-row connections inside data centers and enterprise server rooms. It uses an 850 nm optical wavelength and pushes data at up to 25.78 Gbps, giving virtualized workloads, storage traffic, and high-performance applications the headroom they need.

Power draw stays low at only 1.2 watts, which helps keep thermal loads under control in high-density deployments. The module is rated to operate from 32 °F to 158 °F, so it remains dependable in a wide range of controlled environments.

Whether you are building a new 25 GbE fabric, expanding a VMware cluster, or refreshing an older 10 GbE network, this Intel transceiver offers a straightforward path to higher throughput with minimal disruption.
