SFP-10G-RJ45 10 Gbps copper transceiver, CBO - SFP module for 10GBASE-T

The SFP-10G-RJ45 10 Gbps copper transceiver from BlueOptics is a hot-pluggable SFP+ module that provides 10GBASE-T connectivity over standard RJ45 copper cabling. Designed to fit compatible SFP+ ports in switches, routers or servers, this module enables 10 Gigabit Ethernet links using Cat6 or Cat6a cables, allowing straightforward extension or adaptation of existing network infrastructure in data centers, server rooms and enterprise environments.

Advantages

This 10 Gbps copper transceiver supports backward-compatible Ethernet operation over widespread copper cabling and offers hot-pluggable installation for minimal downtime. Its RJ45 interface simplifies integration into networks that rely on Cat6/Cat6a infrastructure without the need to replace existing copper runs. The compact SFP+ form factor reduces space requirements in equipment chassis and permits flexible port configuration across devices that accept SFP+ modules.

Suitable for

• Upgrading switches or servers to 10GBASE-T without rewiring
• Short to medium copper runs in data centers and server rooms
• Enterprise wiring closets and aggregation points using Cat6/Cat6a
• Temporary or permanent deployments where fiber is impractical

Key specifications

• Interface: SFP+ module with RJ45 connector
• Data rate: 10 Gbps (10GBASE-T)
• Cabling: Designed for Cat6 and Cat6a copper cabling
• Form factor: Hot-pluggable SFP+ (compact transceiver)
• Typical reach: supports short to medium distances over copper (dependent on cable quality)
• Power characteristics: low-profile SFP+ power consumption suitable for rack equipment

How to use

Insert the SFP-10G-RJ45 module into a compatible SFP+ slot on your switch, router or server while the device is powered according to the equipment manual for hot-pluggable modules. Connect a Cat6 or Cat6a cable to the module's RJ45 port and to the corresponding network endpoint. Verify link status and speed on the host device; configuration may require enabling 10G ports or adjusting auto-negotiation settings in the network equipment management interface. For reliable 10 Gbps links, use quality-certified cabling and proper RJ45 terminations.

Recommendations

Use Cat6a cabling for longer copper runs and to achieve the most reliable 10 Gbps performance. Check compatibility lists for the host equipment to confirm SFP+ module support and update device firmware if necessary to ensure correct recognition and operation of the transceiver.
