SFP Transceiver CBO SFP-10G-RJ45-80M 10 Gbps RJ45 copper, up to 80 m

The BlueOptics SFP Transceiver CBO SFP-10G-RJ45-80M is a compact SFP+ module that delivers 10 Gbps Ethernet over standard RJ45 copper cabling with a maximum reach of 80 metres. Intended for use in network switches, routers and servers with SFP+ ports, this transceiver supports 10GBASE-T links for short-distance uplinks and server connections, offering a compatible form factor for hot-plug installation and low-latency data transfer suitable for data centre and enterprise environments.

Advantages

This SFP+ RJ45 copper transceiver enables 10 Gbps connectivity without replacing existing Cat6/Cat6a cabling, reducing deployment complexity and cost for short runs. Its SFP+ form factor provides plug-and-play compatibility with equipment that accepts SFP+ copper modules, while delivering low latency and wire-rate throughput for demanding network applications. The module is designed for easy installation and hot-swap operation, helping to minimise downtime during upgrades or maintenance.

Suitable for

• Short-distance 10G uplinks between switches in racks or adjacent racks
• Server-to-switch 10G connections over copper cabling
• Top-of-rack and aggregation links in data centre pods
• Network equipment in office or campus environments using Cat6/Cat6a cabling

Key specifications

• Interface: SFP+ form factor with RJ45 copper connection
• Data rate: 10 Gbps (10GBASE-T)
• Maximum reach: up to 80 metres over appropriate copper cabling
• Cabling type: twisted-pair copper (Cat6/Cat6a recommended for 10G)
• Latency: low-latency operation suitable for high-performance networks
• Installation: hot-pluggable module for SFP+ ports

How to use

Insert the transceiver into a compatible SFP+ port on the switch, router or server until it seats securely, then connect the RJ45 copper cable to the module. Ensure the copper cable and connectors comply with 10GBASE-T requirements (Cat6 or Cat6a recommended) and that link negotiation settings on both devices support 10 Gbps operation. After physical installation, verify link status in the device management interface and monitor performance metrics to confirm stable 10 Gbps throughput.

Recommendations

For reliable 10 Gbps links up to 80 metres, use high-quality Cat6a or verified Cat6 cabling and avoid excessive cable bundling or electrical interference. Check device compatibility lists for supported SFP+ RJ45 modules and ensure firmware or driver updates are applied when required. For distances near the 80 m limit, test throughput and error rates under expected traffic conditions.
