SFP+ to RJ45 Adapter | 1G/2.5G/5G/10GbE Ethernet Converter

Get 10GbE speeds out of your existing copper cabling no fibre required. This SFP+ to RJ45 adapter converts any standard SFP+ port on your switch, router, or NIC into a 10GBASE-T Ethernet port, running full 10 Gigabit over Cat6a cable at distances up to 100 metres.

It auto-negotiates across 1GbE, 2.5GbE, 5GbE, and 10GbE, so it plays nicely with everything from legacy gear to a modern multi-gig network. Plug it in, connect your Ethernet cable, and you’re done no drivers, no configuration.

Why choose this adapter?

Skip the fibre bill. Fibre transceivers, patch leads, and termination add up fast. If your run is under 100 m, Cat6a copper delivers the same 10GbE for a fraction of the cost and you can probably use cabling you already have in the wall.

One module, four speeds. Auto-negotiation steps the link down to 5G, 2.5G, or 1G automatically when the connected device can’t do 10G. That makes it a safe buy even if parts of your network haven’t been upgraded yet.

Hot-swappable, zero downtime. Install or replace the module without powering down your switch. It slots into standard SFP+ ports and shows up as a copper 10G link nothing to configure.

Runs cool, sips power. Under 2.5W draw with a heat-optimised housing for stable 24/7 operation in enclosed racks and cabinets.

Key specifications

Compatibility

Works with SFP+ slots on switches, routers, NICs, and NAS/SAN devices from major brands including Ubiquiti (UniFi), MikroTik, Cisco, Netgear, TP-Link, Dell, HP, Juniper, Arista, and Brocade.

Perfect for

• Home labs and enthusiasts — 10G links between your NAS, workstation, and switch without touching fibre.
• Small business networks — add multi-gig copper uplinks to an SFP+ switch you already own.
• Server rooms — short high-speed runs between servers, storage, and top-of-rack switches over existing Cat6a.
• Mixed-speed upgrades — connect 2.5G and 5G devices today, knowing the same module handles 10G tomorrow.

What’s the catch with copper 10G?

Honest note: 10GBASE-T modules run warmer than fibre optics and draw more power that’s physics, not a defect. This module’s <2.5W draw and heat-dissipating shell keep it well within safe SFP+ port limits, but if you’re filling every cage in a dense switch with copper modules, leave airflow room. For runs beyond 100 m, fibre remains the right tool.

For everything else this is the cheapest, simplest way to get 10 Gigabit over the cables you already own.
