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

BlueOptics SFP-10G-RJ45-80M is an SFP+ copper transceiver that delivers 10 Gbps Ethernet over standard RJ45 connectors. Intended for insertion into SFP+ slots, this module enables 10GBASE-T connectivity over twisted-pair cabling up to 80 meters when used with Cat6a or Cat7 cabling. It provides a practical alternative to fiber when connecting switches, servers and network appliances within data centers, wiring closets or campus environments that use copper infrastructure.

Advantages

The transceiver supports full 10 Gbps throughput with low latency and conforms to 10GBASE-T electrical signalling, allowing straightforward integration with existing RJ45 infrastructure. Its compact SFP+ form factor preserves port density on network equipment while providing backward-compatible operation with standard copper patching. The module reduces the need for media conversion and simplifies deployment where fiber optic cabling is not available or where copper termination is preferred.

Suitable for

• Connecting SFP+ network ports to RJ45-based switches and servers
• Short 10G links inside data centers and server rooms up to 80 meters
• Upgrading copper-based aggregation and access layers to 10 Gbps
• Temporary or permanent copper connections where fiber routing is impractical

Key specifications

• Interface: SFP+ form factor with RJ45 connector
• Standard: 10GBASE-T (10 Gbps Ethernet over twisted-pair)
• Maximum reach: up to 80 meters over Cat6a/Cat7 cabling (typical)
• Latency: designed for low-latency 10 Gbps operation
• Power and thermal: complies with SFP+ module power envelopes suitable for typical switch ports

How to use

Insert the SFP-10G-RJ45-80M module into any compatible SFP+ slot according to the host device instructions, ensuring the module latches securely. Connect a shielded Cat6a or Cat7 RJ45 patch cable between the module’s RJ45 port and the remote device. Verify link status and speed on both ends of the connection through the switch or server management interface and monitor for any required link negotiation settings. Follow host vendor guidance for module compatibility and firmware or driver requirements if applicable.

Recommendations

Use high-quality Cat6a or Cat7 cables for reliable 10G performance and keep cable runs within the recommended 80-meter distance. Ensure adequate airflow and thermal conditions in the host device, and check vendor compatibility lists for supported SFP+ copper modules to avoid interoperability issues.
