SFP+ Copper Transceiver CBO SFP-10G-RJ45 10 Gbps, 10GBASE-T, RJ45

CBO SFP-10G-RJ45 is an SFP+ copper transceiver that provides 10 Gbps Ethernet connectivity over standard RJ45 twisted-pair cabling using the 10GBASE-T standard. Designed for SFP+ ports on switches, servers and other network equipment, this hot-pluggable module allows integration of 10 Gigabit links where fiber is not required or where existing copper infrastructure is preferred. The module supports short to moderate copper runs and is backward compatible with lower speed Ethernet when supported by the host device.

Advantages

The SFP+ copper transceiver delivers 10 Gbps performance over familiar RJ45 cabling, enabling cost-effective use of existing copper infrastructure. Hot-pluggable design simplifies installation and maintenance without powering down equipment. Compatibility with standard SFP+ ports and 10GBASE-T framing ensures straightforward integration into mixed network environments. The module is suitable for scenarios that require low-latency, high-bandwidth copper links and provides predictable electrical interface characteristics for copper connections.

Suitable for

• Connecting switches and top-of-rack servers over copper cabling
• Upgrading legacy copper links to 10 Gbps without replacing cabling
• Short to moderate length links in data centers, server rooms and wiring closets
• Environments requiring hot-swappable 10G copper connectivity

Key specifications

• Interface: SFP+ form factor with RJ45 copper port
• Data rate: 10 Gbps (10GBASE-T)
• Cabling: Unshielded or shielded twisted-pair copper (Cat6a/Cat7 recommended for full 10G at longer distances)
• Link distance: suitable for short to moderate copper runs (distance depends on cable category and environment)
• Hot-pluggable: supports live insertion and removal when host supports SFP+ hot-swap

How to use

Insert the transceiver into a compatible SFP+ slot on your switch, server or network device until it clicks into place. Connect an appropriate RJ45 twisted-pair cable between the transceiver and the remote device. Verify that the host device recognizes the module and negotiates the 10GBASE-T link; adjust link settings in the device management interface if needed. For stable 10 Gbps operation, use cabling and patch panels of sufficient category and quality, and ensure devices at both ends support the required speed.

Recommendations

For reliable 10 Gbps links, use Cat6a or Cat7 cabling for longer runs and ensure proper cable termination and quality. Confirm SFP+ slot compatibility with copper SFP+ modules in your network equipment documentation. When deploying in dense installations, allow for adequate airflow and equipment cooling, and perform link tests after installation to validate performance.
