1000BASE-T SFP Copper Module

This 1000BASE-T SFP transceiver converts an SFP+ port to an RJ-45 Ethernet connection. It suits network administrators adding copper uplinks to switches or routers that accept SFP+ modules. The unit operates across commercial temperatures from 0 to 70°C and complies with MSA standards for broad compatibility. It targets environments where fibre is not required but a hot-pluggable copper link is.

Thermals Noise and Power Draw

The module runs within a commercial temperature range of 0 to 70°C (32 to 158°F) without active cooling. Passive operation means no fan noise is added to the rack. Power consumption scales with the negotiated link speed, which can be 10Gbps, 5Gbps, 2.5Gbps or 1000Mbps. Heat output remains low enough for dense side-by-side installation in standard SFP+ cages.

Build Fit and Freedoms

The SFP+ form factor plugs directly into any MSA-compliant SFP+ cage, freeing a fibre port for copper cabling. At 1000Mbps the link reaches 100 metres over Cat5e or better; at 2.5Gbps and 5Gbps the reach is 50 metres; at 10Gbps it drops to 30 metres. No additional transceivers or media converters are needed, simplifying cable management in the rack.

Questions about this item

How do I install the SFP transceiver and what step is often missed?

Insert the module into an SFP+ port until it clicks, then connect a Cat5e or better RJ45 patch cable; the step often missed is confirming the link negotiates at the intended speed rather than defaulting to 1000Mbps.

What maintenance or replacement will this copper module need over time?

No scheduled maintenance is required; replacement is only needed if the RJ45 port suffers physical damage or if the unit exceeds the 0 to 70°C commercial temperature range during sustained operation.

What distance limit appears first when running at 10Gbps continuously?

At 10Gbps the cable distance is limited to 30 metres, which is the first constraint reached before the 50‑metre limit at 5Gbps or 2.5Gbps and the 100‑metre limit at 1000Mbps.
