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

The BlueOptics SFP-10G-RJ45 is a 10 Gbps SFP+ transceiver module for 10GBASE-T copper Ethernet connections over RJ45. It provides 10 Gigabit performance in a compact SFP+ form factor, enabling short-distance high-speed links over Cat6 or Cat6a copper cabling. The module is designed for use with SFP+ ports on switches, servers and other network equipment and supports hot-pluggable installation for quick upgrades from Gigabit to 10G copper connections.

Advantages

This SFP-10G-RJ45 module delivers 10 Gbps throughput in a small SFP+ footprint, saving space in rack-mounted equipment while allowing copper cabling reuse. It supports hot-swapping for minimal service interruption during installation or replacement. The RJ45 interface accepts standard Cat6/Cat6a cables, simplifying deployment without the need for fiber optics or specialized transceivers. The design targets compatibility with a wide range of network devices that provide SFP+ ports, enabling flexible network architecture choices.

Suitable for

• Upgrading server uplinks from 1 Gbps to 10 Gbps over existing copper cabling
• Short-range 10 Gigabit connections between switches in a rack or between adjacent racks
• High-performance Ethernet links for storage, virtualization or hyperconverged infrastructure within a data center
• Network equipment testing and lab environments requiring 10GBASE-T copper links

Key specifications

• Data rate: 10 Gbps (SFP+ compatible)
• Interface: RJ45 connector for 10GBASE-T copper Ethernet
• Cable type: Compatible with Cat6 and Cat6a cabling for short-reach 10G links
• Form factor: SFP+ hot-pluggable transceiver module
• Typical reach: Short-distance 10G connections (distance depends on cable category and quality)

How to use

Insert the SFP-10G-RJ45 module into an empty SFP+ port on a compatible switch, server or network appliance until it clicks into place. Connect a suitable RJ45 copper cable (Cat6 or Cat6a) between the module and the corresponding RJ45 port on the remote device. The module supports hot-plugging, so it can be installed or removed while the host device remains powered on, though follow standard change-management procedures to avoid network disruption. Verify link status and speed in the host device management interface after installation.

Recommendations

Use high-quality Cat6a cabling for longer short-range 10G links and to ensure margin for performance and reduced crosstalk. Confirm SFP+ port compatibility and firmware or vendor restrictions on third-party transceivers in your network devices before deployment. For reliable 10GBASE-T performance, maintain proper cable routing, avoid excessive patching, and test link negotiation at 10 Gbps after installation.
