SFP+ copper transceiver CBO SFP-10G-RJ45 10G for RJ45 copper cabling

The CBO SFP-10G-RJ45 is an SFP+ copper transceiver that provides 10 Gigabit Ethernet over standard RJ45 copper cabling. Designed for installation in compatible SFP+ ports, this module enables high-speed copper links without the need for fiber optics, making it suitable for upgrades or expansions in server, switch and network interface hardware that support SFP+ copper modules. The module is intended for use in environments where existing Cat6a/Cat7 copper cabling is available and a short- to medium-range 10G connection is required.

Advantages

The transceiver supports full 10G throughput on copper infrastructure and offers a plug-and-play form factor for straightforward installation into SFP+ cages. It eliminates the need to rewire with fiber when copper cabling is already deployed, reducing installation complexity and allowing reuse of existing cabling. The module is compact and compatible with standard SFP+ ports that accept copper transceivers, enabling flexible deployment across compatible network equipment.

Suitable for

• 10 Gigabit Ethernet links between switches and servers over RJ45 copper cables
• Network upgrades where fiber is not required or available
• Data center top-of-rack connectivity using existing copper infrastructure
• Short- to medium-reach 10G connections within enterprise or campus networks

Key specifications

• Interface: SFP+ module for RJ45 copper cabling
• Data rate: 10 Gbit/s
• Connector type: RJ45 (8P8C)
• Cabling: Compatible with Cat6a/Cat7 twisted-pair copper cable for 10G links
• Form factor: SFP+ (compact hot-pluggable)
• Typical reach: short- to medium-range over copper (dependent on cable category and installation)

How to use

Insert the SFP+ copper transceiver into a compatible SFP+ port on the switch, server or network interface card until it clicks into place. Connect an RJ45 copper cable of appropriate category (for example Cat6a or Cat7) between devices. Ensure device firmware and drivers support SFP+ copper modules; if necessary, configure link speed and duplex settings on the network equipment. Power on and verify link status through the host device management interface or LEDs to confirm a stable 10G connection.

Recommendations

Use high-quality Cat6a or higher-rated copper cable and proper termination to achieve reliable 10G performance. Verify compatibility with the host device’s SFP+ slot and check for any vendor firmware requirements. For longer-distance 10G links or environments with high electromagnetic interference, consider fiber optic alternatives. Handle the module carefully and avoid touching connector contacts; store unused modules in protective packaging when not installed.
