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 a SFP+ copper transceiver module that provides 10 Gbps Ethernet over an RJ45 interface (10GBASE-T). It is intended for short-distance copper connections and enables 10 Gbit/s links over Cat6a or Cat7 structured cabling up to 80 metres. The module is designed to be inserted into compatible SFP+ ports on switches, routers or servers to add native 10G RJ45 connectivity without requiring a dedicated fixed RJ45 port.

Advantages

The transceiver supports full 10 Gbps throughput while using standard twisted-pair copper cabling, allowing reuse of existing Cat6a/Cat7 infrastructure. It fits into SFP+ slots to provide flexible port configuration and simplifies upgrading devices that lack built-in 10G RJ45 interfaces. The unit is compact, hot-pluggable and interoperable with equipment that supports SFP+ copper modules, delivering low-latency copper connectivity for aggregation and server links.

Suitable for

• Adding 10G RJ45 ports to SFP+ ports on network switches and routers
• High-speed server uplinks and top-of-rack aggregation
• Short-distance 10 Gbps links over Cat6a/Cat7 cabling within data centres or wiring closets
• Upgrading legacy copper-based networks to 10G without re-cabling to fibre

Key specifications

• Interface: SFP+ form factor with RJ45 10GBASE-T copper port
• Data rate: 10 Gbps
• Cabling: Compatible with Cat6a and Cat7 twisted-pair copper cabling
• Maximum reach: Up to 80 metres over suitable Cat6a/Cat7 cabling
• Hot-pluggable: Yes
• Typical use: Short-reach copper connections for servers and switches

How to use

Install the SFP+ copper transceiver into an empty SFP+ slot on a compatible switch, router or server until it latches. Connect the RJ45 patch cable from the transceiver to the remote device using Cat6a or Cat7 cabling to achieve the specified reach. Verify link negotiation and speed on the host device; some systems may require enabling 10GBASE-T or confirming module compatibility in device firmware. For best results, use high-quality shielded cables and test links with appropriate network tools.

Recommendations

Use this module where short 10 Gbps copper links are needed and structured cabling of Cat6a or Cat7 is available. Check the switch or server compatibility list for supported SFP+ copper transceivers and ensure firmware is up to date. For distances approaching the maximum 80 m, prefer Cat7 or certified Cat6a cabling and minimize intermediate patch panels to reduce signal loss.
