HP 10GBase-T SFP+ Transceiver

The HP 813874-B21 is a single-port SFP+ transceiver designed for 10 Gigabit Ethernet connectivity over copper twisted-pair cabling. It fits standard SFP+ slots in switches, routers or servers, providing an RJ-45 interface for data networking applications.

30 metre reach over Cat 6a or Cat 7

This module supports 10GBase-T operation up to 30 metres when used with Category 6a or Category 7 twisted-pair cable. The 10 Gbit/s data rate is maintained within this distance limit; longer runs or lower-category cables are not supported by the transceiver specification.

Verify SFP+ slot and MSA compliance before ordering

Ensure your host equipment accepts MSA-compliant SFP+ modules and can supply the required power for a 10GBase-T copper transceiver. Confirm the switch or server port is configured for 10GBase-T operation and that Cat 6a or Cat 7 patch cables are available for the intended link length.
