Copper 10GBASE-T SFP+ module CBO SFP-10G-RJ45-MR-BO — 10 Gbps, RJ45, up to 30 m

CBO SFP-10G-RJ45-MR-BO is a copper SFP+ transceiver that provides 10GBASE-T connectivity over standard RJ45 copper cabling for distances up to 30 m. Designed for 10 Gbps uplinks, the module fits into SFP+-compatible switches, routers and network interface cards to deliver short-range server-to-switch or switch-to-switch links without the need for fiber. The module supports autonegotiation and the physical characteristics of 10GBASE-T to enable straightforward integration into existing copper-based infrastructure.

Advantages

The module delivers 10 Gbps data rates over widely used Cat6/Cat6a copper cabling, reducing the need for fiber in short-range connections and simplifying cabling management. Its SFP+ form factor allows hot-pluggable installation in compatible ports and helps conserve equipment slot space. The transceiver is compatible with standard RJ45 connectors and supports power-efficient operation appropriate for data center access and aggregation layers.

Suitable for

• 10 Gbps uplinks between servers and top-of-rack switches over short copper runs
• Short-distance switch-to-switch or router-to-switch connections within racks or adjacent racks
• Upgrading copper-based networks to 10G where fiber deployment is unnecessary or cost-prohibitive
• Temporary links, lab environments, and test benches requiring 10G copper connectivity

Key specifications

• Interface: SFP+ module with RJ45 copper connector
• Data rate: 10 Gbps (10GBASE-T)
• Maximum supported distance: up to 30 m over suitable twisted-pair cabling
• Cabling: compatible with Cat6/Cat6a twisted-pair copper cable
• Form factor: hot-pluggable SFP+ transceiver

How to use

Insert the SFP+ module into a compatible SFP+ port on your switch, router or network adapter while the device is powered on or according to the host equipment's guidelines for hot-plugging. Connect a suitable RJ45 terminated Cat6/Cat6a cable between the module and the remote device. Confirm link status and negotiated speed in the host equipment management interface; the module operates as a standard 10GBASE-T link and typically requires no additional configuration on compliant platforms. Ensure that connected devices support SFP+ copper transceivers and that firmware or driver settings do not block third-party modules if applicable.

Recommendations

For reliable 10 Gbps performance up to 30 m, use high-quality Cat6a or properly installed Cat6 cabling, maintain proper cable routing to avoid electromagnetic interference, and verify compatibility with your network equipment. In installations where heat dissipation and power budget are critical, check the host port's power and thermal specifications before deployment.
