10GBase-T SFP+ Copper Transceiver

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.

Sustained 10 Gbps throughput over copper

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.

Practical limits of the 10GBase-T interface

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.

Questions about this item

How much power does the SL-10GE-T draw when running continuously at 10 Gbps?

The module consumes a maximum of 2.5 W during 10 Gbps operation over copper, keeping heat output low inside a switch chassis.

Which cabling and switch ports are needed for this transceiver to operate?

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.

Will the SL-10GE-T negotiate down to 2.5 Gbps or 1 Gbps on older copper links?

Yes, the module supports 10 Gbps, 2.5 Gbps and 1 Gbps rates automatically on existing Cat. 5e or Cat. 6 runs.
