SFP-10G-RJ45 10 Gbps Transceiver, CBO, SFP module for 10GBASE-T copper

The BlueOptics SFP-10G-RJ45 is an SFP+ transceiver module that delivers 10 Gbps Ethernet over standard copper cabling using an RJ45 interface. Designed for insertion into compatible SFP+ ports, this 10GBASE-T module enables short-range copper links between switches, routers and servers without replacing existing structured cabling. The unit supports 10 Gigabit throughput while maintaining backward compatibility with lower Ethernet speeds where supported by connected equipment.

Advantages

This SFP module provides flexible deployment by converting an SFP+ port to a 10GBASE-T RJ45 copper port, allowing use of familiar Cat6/Cat6a cabling for short-reach connections. It reduces the need for fiber infrastructure in server rooms and wiring closets when copper links are sufficient. The small-form-factor pluggable design supports hot-swapping and simple integration into systems with available SFP+ slots, enabling cost-effective upgrades from Gigabit to 10 Gigabit Ethernet.

Suitable for

• Short-range 10 Gbps uplinks between switches and aggregation equipment
• 10G copper connections to servers and storage systems
• Migrations from 1 Gbps to 10 Gbps where existing Cat6/Cat6a cabling is in place
• Network equipment that provides SFP+ ports and requires 10GBASE-T connectivity

Key specifications

• Data rate: 10 Gbps (10GBASE-T)
• Interface: SFP+ host connector with RJ45 copper port
• Cable type: Compatible with Cat6/Cat6a copper cabling for short-range links
• Form factor: SFP+ (small form-factor pluggable)
• Reach: Designed for short-distance copper connections (typical data center/closet runs)
• Hot-swappable: Yes, for in-service replacement and upgrades

How to use

Insert the transceiver into a compatible SFP+ slot on your switch, router or server until it clicks into place. Connect an RJ45 cable of appropriate category (Cat6 or Cat6a recommended) between the module and the remote device. Configure link speed and duplex settings on both ends if required by your equipment; many systems negotiate 10 Gbps automatically when the module and cable support it. Follow your hardware vendor’s guidelines for handling electrostatic-sensitive components and perform any necessary firmware or driver updates to ensure compatibility.

Recommendations

Use high-quality Cat6a cabling for reliable 10 Gbps performance over longer short-reach runs and keep cable runs within recommended distances for 10GBASE-T. Verify compatibility with the host device’s SFP+ slot and consult device documentation for supported transceiver lists when planning deployments.
