SFP+ Copper Transceiver CBO SFP-10G-RJ45 for 10G Ethernet over Cat6/Cat6a

The SFP+ Copper Transceiver CBO SFP-10G-RJ45 for 10G Ethernet over Cat6/Cat6a is a compact module that enables 10 Gigabit Ethernet connectivity over standard RJ45 copper cabling. Designed for insertion into SFP+ ports on switches, routers and servers, this transceiver supports 10G data rates for short- to medium-range links where Cat6 or Cat6a cabling is available. It allows network equipment to use existing copper infrastructure to achieve higher bandwidth without deploying fiber, and is intended for environments that require reliable, low-latency wired connections.

Advantages

This SFP+ copper transceiver provides plug-and-play installation for SFP+ compatible devices and eliminates the need for fiber optic hardware when copper cabling is already installed. The module supports standard 10 Gigabit Ethernet over Cat6 and Cat6a cables, offering cost-effective upgrades of existing network segments. Its small form factor conserves port space in rack-mounted equipment, and compatibility with standard SFP+ interfaces reduces integration complexity across switches, routers and servers.

Suitable for

• Upgrading server uplinks and switch-to-switch connections to 10G over existing Cat6/Cat6a cabling
• Short- to medium-range 10G links within data centers, wiring closets and server rooms
• Environments where fiber deployment is impractical or more costly than using copper

Key specifications

• Form factor: SFP+ (10 Gigabit Small Form-factor Pluggable Plus)
• Interface: RJ45 for copper twisted-pair cabling
• Supported data rate: 10 Gbps
• Cable type: Cat6 and Cat6a twisted-pair copper cabling
• Link range: short- to medium-range 10G links over copper (depends on cable category and quality)
• Compatibility: Designed for use with devices featuring SFP+ ports

How to use

Insert the SFP+ transceiver into an available SFP+ slot on a compatible switch, router or server until it seats firmly. Connect an RJ45 terminated Cat6 or Cat6a cable between this transceiver and the corresponding RJ45 port or another SFP+ copper transceiver on the remote device. Ensure both connected devices are configured for 10G operation and that their SFP+ ports support copper modules. After installation, verify link status and network configuration in the device management interface and monitor for proper negotiation at 10 Gbps.

Recommendations

To achieve reliable 10G performance, use high-quality Cat6a cabling for longer or noise-prone runs and keep connector terminations clean. Confirm that the host devices’ firmware and drivers support SFP+ copper modules and check link negotiation settings if the connection falls back to lower speeds. For optimal results in data center environments, follow structured cabling guidelines and maintain recommended cable lengths for 10G over copper.
