Copper SFP+ module delivers 10 Gbps over RJ45 up to 30 metres, hot-pluggable with metal housing
The Black Box SL-10GE-T converts an SFP+ port to a 10GBase-T RJ45 link using Cat 5e or better cabling. It targets network engineers and integrators who need copper connectivity on fibre switches, media converters or routers without replacing existing infrastructure. Hot-pluggable operation allows insertion or removal without network downtime.
The module maintains line-rate 10 Gbps across the full 30 m reach with a maximum draw below 2.5 W. Metal housing dissipates heat during continuous load so the transceiver stays within thermal limits inside densely populated chassis. Auto-negotiation steps down to 2.5 Gbps or 1 Gbps when linked to slower partners.
IEEE 802.3U defines the electrical signalling but the 30 m ceiling is set by copper attenuation at 10 Gbps. Beyond that distance a fibre SFP+ module such as an SR or LR variant is required. The RJ45 connector also prevents use in environments that mandate optical isolation or extended temperature ratings.

The module consumes a maximum of 2.5 W during 10 Gbps operation over copper, keeping heat output low inside a switch chassis.
You need Cat. 5e or better twisted-pair cable up to 30 m and a free SFP+ port on the host switch or media converter.
Yes, the module supports 10 Gbps, 2.5 Gbps and 1 Gbps rates automatically on existing Cat. 5e or Cat. 6 runs.
