SFP-10G-RJ45 10 Gbps copper transceiver, CBO, SFP+ module for 10 Gigabit Ethernet

The BlueOptics SFP-10G-RJ45 is a compact SFP+ copper transceiver module that provides 10 Gbps connectivity over standard RJ45 ports using Cat6a or Cat7 cabling. Designed for hot-pluggable installation in switches, routers and servers, the module enables low-latency 10 Gigabit Ethernet links without the need for fiber optics. Its small form factor supports high-density deployments in data center, aggregation and enterprise network environments where short to medium copper runs are preferred.

Advantages

The module offers a cost-effective alternative to fiber-based 10G links by using existing copper infrastructure. Hot-pluggable design simplifies installation and replacement without system downtime. The SFP+ form factor supports high port density and compatibility with a wide range of 10 Gigabit Ethernet devices that accept SFP+ copper modules. Low latency and stable electrical performance make the transceiver suitable for latency-sensitive applications and standard network traffic.

Suitable for

• 10 Gigabit connections between switches and servers over Cat6a/Cat7
• Data center top-of-rack and aggregation links for short to medium distances
• Enterprise LAN uplinks where fiber is not available or cost-effective
• Hot-swap replacement or port upgrades in existing SFP+ compatible hardware

Key specifications

• Interface: SFP+ form factor with RJ45 electrical interface
• Data rate: 10 Gbps (full duplex)
• Cabling: Compatible with Cat6a and Cat7 copper cabling
• Connector type: Standard RJ45
• Operating range: Designed for short to medium copper link lengths (typical 30–100 m depending on cable and environment)
• Hot-pluggable: Yes
• Latency: Low electrical latency suitable for 10G traffic

How to use

Insert the SFP-10G-RJ45 module into any compatible SFP+ port on a switch, router or server until it clicks into place. Connect a properly rated Cat6a or Cat7 RJ45 cable between the module and the remote device. Ensure the host device supports SFP+ copper transceivers and configure the network interface with the correct speed and duplex settings if required. The module supports hot-swap operations, allowing replacement or installation without powering down compatible equipment.

Recommendations

Use high-quality Cat6a or Cat7 cables and proper grounding to achieve reliable 10 Gbps links. Confirm compatibility with the host device’s firmware or vendor compatibility list before deployment. For optimal performance, keep copper runs within recommended distances and avoid excessive bending or electromagnetic interference sources.
