SFP+ Copper Module CBO 838327-B21-BO 10GBASE-T, up to 30 m

The SFP+ Copper Module CBO 838327-B21-BO 10GBASE-T is a compact 10 Gigabit Ethernet transceiver designed for short-distance copper connections over twisted-pair cabling. Supporting 10GBASE-T at full duplex, this module fits SFP+ ports that accept 10GBASE-T modules and is intended for use in servers, switches and network appliances where a copper interface is preferred or existing infrastructure requires RJ45 connectivity. The module supports a reach of up to 30 meters over Cat6/Cat6a class cabling and delivers a space-saving alternative to larger RJ45 ports while preserving 10 Gbps bandwidth for local interconnects.

Advantages

This SFP+ copper transceiver offers a small form factor that simplifies port density and cabling management in rack-mounted equipment. It enables 10GBASE-T connectivity without modifying existing copper cabling plants, providing compatibility with standard twisted-pair Ethernet infrastructure. The module reduces the need for separate media converters and allows hot-pluggable installation into compatible SFP+ slots for rapid deployment and maintenance.

Suitable for

• Short-reach 10 Gigabit connections between switches and access layer devices
• Server uplinks to top-of-rack or aggregation switches
• Network appliances and SAN front-end connectivity requiring RJ45 copper links
• Retrofit or mixed-media environments where copper cabling is retained

Key specifications

• Interface type: SFP+ form factor supporting 10GBASE-T
• Data rate: 10 Gbps, full duplex
• Media: Twisted-pair copper (RJ45)
• Maximum reach: up to 30 meters over suitable Cat6/Cat6a cabling
• Connector: 8P8C (RJ45) compatible
• Compatibility: Designed for devices with SFP+ ports that accept 10GBASE-T modules

How to use

Install the SFP+ Copper Module into an empty SFP+ slot on the target switch, server or network appliance while the host device is powered down or following the vendor’s hot-swap guidelines. Connect a suitable Cat6 or Cat6a twisted-pair cable to the module’s RJ45 connector and to the remote device. Ensure that the host device firmware or operating system recognizes 10GBASE-T SFP+ modules and that link settings are configured for 10 Gbps full duplex. Monitor link LEDs or management interfaces to verify link negotiation and operational status.

Recommendations

For reliable 10 Gbps performance at the specified reach, use high-quality Cat6a or certified Cat6 cabling, maintain proper cable termination and avoid running cables near strong electromagnetic interference sources. Confirm that the equipment vendor supports 10GBASE-T SFP+ modules in the specific device model and keep device firmware up to date to ensure compatibility and optimal link stability.
