SFP28 modules send data very fast, up to 25Gbps. They fit in the same small slots as older SFP+ modules. Enter the SFP28 transceiver, the crucial bridge technology delivering cost-effective, high-density 25 Gigabit per second (25G) connectivity. Trusted by 260K+ Enterprise Users. Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver, such as for a fiber-optic cable or a copper. SFP28 is widely used for 25G links in servers, switches, and modern data center networks. That makes fiber choice more important than many buyers expect. They have supporting circuitry to enable 25G speed transceiver, DAC, and AOC components.
