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

The SFP-10G-RJ45 Copper SFP+ Transceiver by BlueOptics delivers 10 Gigabit Ethernet connectivity over standard twisted-pair cabling using an RJ45 interface. Designed for installation in SFP+ ports, this module converts SFP+ host interfaces to copper links compatible with Cat6 and Cat6a cabling for short- to medium-range connections. The compact transceiver enables integration with switches, routers and servers that require 10G copper uplinks while preserving a plug-and-play installation experience and standard SFP+ form-factor.

Advantages

This SFP+ RJ45 module provides a cost-effective way to extend 10 Gigabit Ethernet to existing copper infrastructure without replacing cabling. Its SFP+ form factor supports hot-swappable installation and straightforward compatibility with devices that accept SFP+ copper modules. The transceiver is suitable for environments where fiber deployment is impractical or where consolidation to Cat6/Cat6a is already in place, offering predictable link performance for short- to medium-distance connections.

Suitable for

• 10G uplinks between switches and aggregation points over Cat6/Cat6a
• High-performance server connections to top-of-rack switches
• Edge and distribution layer links where fiber is not available
• Network upgrades that reuse existing twisted-pair cabling

Key specifications

• Interface: SFP+ host, RJ45 copper link
• Data rate: 10 Gigabit Ethernet (10 Gbps)
• Cable type: Compatible with Cat6 and Cat6a twisted-pair cabling
• Distance: Short- to medium-range over specified copper cable (performance depends on cable quality and environment)
• Form factor: SFP+ (hot-pluggable)
• Operating environment: Designed for standard networking equipment environments

How to use

Insert the transceiver into an available SFP+ slot on a compatible switch, router or server until it clicks into place. Connect a Cat6 or Cat6a RJ45 cable from the transceiver’s RJ45 port to the remote device. Ensure both ends support 10G operation and verify link status on connected equipment. No additional configuration is typically required beyond enabling the SFP+ port and confirming speed/duplex settings on the host device.

Recommendations

For reliable 10G links, use high-quality Cat6a cabling for longer short- to medium-range runs and ensure terminations meet industry standards. Validate device compatibility with SFP+ copper modules and check switch firmware requirements if link negotiation issues occur. Avoid running copper cables near strong electromagnetic interference sources to preserve signal integrity.
