SFP+ Copper Transceiver CBO SFP-10G-RJ45-80M 10 Gbps, RJ45 10GBASE-T, up to 80 m over Cat6a/Cat7

CBO SFP-10G-RJ45-80M is an SFP+ copper transceiver that enables 10 Gbps Ethernet over standard RJ45 connectors using 10GBASE-T. Engineered for short-range connections, the module supports data transmission up to 80 meters when used with suitable Cat6a or Cat7 cabling. The compact SFP+ form factor allows installation into standard SFP+ ports on switches, servers and network appliances to provide a copper-based 10 Gbps uplink or server port without requiring a dedicated NIC or larger optical module.

Advantages

The transceiver delivers 10 Gbps performance with low latency and compatibility with common RJ45 network infrastructure, reducing the need for fiber in short-distance links. Its SFP+ form factor provides hot-pluggable convenience and space savings in high-density network equipment. The module is designed for interoperability with standard 10GBASE-T copper cables and supports straightforward integration into existing data center and enterprise network setups.

Suitable for

• Short-reach 10 Gbps connections between switches and servers
• High-density network equipment where SFP+ copper uplinks are required
• Data centers and server rooms using Cat6a or Cat7 cabling
• Upgrading 1/10G networks to 10G without fiber installation

Key specifications

• Interface: SFP+ form factor with RJ45 10GBASE-T connector
• Data rate: 10 Gbps
• Maximum reach: up to 80 meters over Cat6a/Cat7 cabling
• Transmission medium: Copper twisted-pair (shielded or unshielded as per cable type)
• Compatibility: Standard SFP+ ports on switches, servers and appliances
• Hot-pluggable design for in-service installation and replacement

How to use

Insert the SFP+ copper transceiver into a compatible SFP+ slot until it latches, then connect a Cat6a or Cat7 RJ45 cable between the module and the remote device. Ensure both ends are configured for 10GBASE-T operation in the connected equipment and verify link status through the host device management interface. For best performance, use certified cabling and confirm that link settings, such as duplex and speed, match on both devices.

Recommendations

Use Cat6a or Cat7 cabling for distances up to 80 m and follow cable routing best practices to minimize electromagnetic interference. Verify compatibility with the target switch or server vendor and keep firmware or driver versions updated where applicable to ensure stable 10 Gbps operation.
