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 delivers 10 Gbps Ethernet over an RJ45 10GBase-T interface. The module is designed for short-reach 10G connections using Cat6a or Cat7 twisted-pair cabling and fits standard SFP+ slots, enabling the addition of copper 10G ports to switches, servers and network appliances without requiring fiber optics.

Advantages

This SFP+ copper transceiver offers straightforward installation in SFP+ ports and supports 10 Gbps data rates with backward compatibility to lower Ethernet speeds when required. It enables cost-effective deployment where existing copper cabling is available, eliminating the need for fiber transceivers or media converters for short-distance links. The compact SFP+ form factor conserves equipment slot space while providing standard RJ45 connectivity and power efficiency optimized for short links.

Suitable for

• Short-distance 10G uplinks between switches in server rooms or wiring closets
• Connecting 10G-capable servers to top-of-rack or aggregation switches
• Upgrading existing Cat6a/Cat7 copper infrastructure to 10 Gbps
• Network appliances and devices with SFP+ ports that require RJ45 connectivity

Key specifications

• Data rate: 10 Gbps (10GBase-T)
• Connector: RJ45
• Medium: Cat6a or Cat7 twisted-pair copper cabling
• Maximum reach: up to 80 meters over Cat6a/Cat7
• Form factor: SFP+
• Supported link modes: 10G with backward compatibility to lower speeds

How to use

Insert the SFP+ copper transceiver into a compatible SFP+ port on a switch, server or network appliance until it clicks into place. Connect one end of a Cat6a or Cat7 RJ45 patch cable to the module’s RJ45 port and the other end to the remote device. Ensure both connected devices are configured for 10G operation and that network settings (speed, duplex, auto-negotiation) match on both ends. Verify link status through device LEDs or management interfaces and monitor for stability during initial operation.

Recommendations

For reliable 10G performance, use quality Cat6a or Cat7 cables and keep link lengths under 80 meters. Verify compatibility with your equipment vendor’s SFP+ port firmware and consult switch or server documentation for any required settings. Avoid using older Cat5e/Cat6 cabling for 10GBase-T at this distance to prevent degraded throughput or link failures.
