A 10 Gbps SFP+ transceiver with an RJ45 connector for 30 m copper links
This transceiver adds a single 10 Gbps RJ45 port to an SFP+ cage. It targets network engineers who need copper uplinks between switches or servers inside the same rack row. The module runs at commercial temperatures from 0 to 70 °C and draws power directly from the host port.
The 10GBase-T standard over twisted pair caps reliable operation at 30 m with Category 6a or better cabling. Longer runs require fibre-based optics instead of this copper module. Link LEDs show power, activity, full-duplex status and negotiated speed for quick diagnostics.
Swapping a fibre SFP+ and patch cords for this module removes the need for patch panels and fusion splicing on runs under 30 m. The jump is worth it when rack-to-rack copper is already installed or when deployment speed outweighs the distance ceiling.
