SFP+ Copper Transceiver CBO SFP-10G-RJ45-80M 10 Gbps RJ45 80 m

The BlueOptics SFP+ Copper Transceiver CBO SFP-10G-RJ45-80M is a compact, hot-pluggable 10 Gigabit Ethernet module that provides RJ45 copper connectivity for short-range links up to 80 meters. Designed for installation in SFP+ slots of switches, routers and servers, this transceiver enables cost-effective migration to 10 Gbps over existing copper infrastructure without the need for fiber optic cabling. The module supports standard Ethernet framing and typical data center topologies where short-distance, high-bandwidth connections are required.

Advantages

This SFP+ copper transceiver offers a space-saving form factor and hot-pluggable operation, simplifying upgrades and maintenance. It delivers 10 Gbps full-duplex performance over standard RJ45 cabling at distances up to 80 meters, reducing the need for fiber conversion equipment. Compatibility with common SFP+ ports makes the module suitable for a wide range of network devices, and its copper interface can lower deployment costs for short-range links.

Suitable for

• Data center server-to-switch uplinks on short runs
• Top-of-rack and middle-of-row connectivity where fiber is not required
• Switch-to-switch aggregation within the same room or adjacent racks
• Upgrading legacy copper networks to 10 Gbps without replacing cabling

Key specifications

• Form factor: SFP+ (hot-pluggable)
• Interface: 10 Gigabit Ethernet over RJ45 (copper)
• Maximum link distance: up to 80 meters over Cat6/Cat6a-class cabling (depending on environment)
• Data rate: 10.3125 Gbps (10GBASE-T compatible)
• Duplex: full-duplex operation
• Power and thermal: designed for typical SFP+ power envelopes and device thermal constraints

How to use

Insert the SFP+ module into an available SFP+ slot on a compatible switch, router or server while the host device is powered on or off, following the host vendor's hot-plug procedures. Connect a shielded twisted-pair Ethernet cable with an RJ45 connector to the module and ensure the other end is connected to the corresponding port on the peer device. Verify link status and negotiated speed through the host device management interface; the module negotiates 10 Gbps operation when supported by both ends. Observe device LEDs or management logs to confirm correct operation and link integrity.

Recommendations

For reliable 10 Gbps performance up to 80 meters, use high-quality Cat6 or Cat6a cabling and maintain proper cable routing to minimize electromagnetic interference and heat exposure. Check compatibility notes from your switch or server vendor for any required firmware or driver settings. In installations where longer distances or lower latency are needed, consider using fiber-based SFP+ optics instead of copper transceivers.
