SFP Transceiver CBO SFP-10G-RJ45-CO-BO 10Gbit/s RJ-45 copper 80m

The BlueOptics SFP-10G-RJ45-CO-BO is a 10 Gbit/s SFP (small form-factor pluggable) transceiver with an RJ-45 copper interface designed for short-distance 10 Gigabit Ethernet links over structured copper cabling. It supports transmission distances up to 80 meters when used with standard Cat6a or Cat7 cables, enabling high-speed connectivity in switches, routers and server modules without replacing existing copper infrastructure. The module provides a compact SFP form factor that fits into compatible SFP+ ports and offers a practical option for data centers and enterprise networks seeking to maintain copper-based links for 10G Ethernet.

Advantages

This SFP copper transceiver offers 10 Gbit/s line rate in a compact SFP form factor, enabling flexibility to use RJ-45 copper connections where fiber is not required. It supports common structured cabling standards up to 80 m over Cat6a/Cat7, reducing the need for immediate cabling upgrades. The module is hot-pluggable for easy installation and replacement and is compatible with a wide range of network devices that accept SFP modules. By enabling short-range copper links at 10G speeds, it simplifies migration paths for network upgrades while maintaining physical compatibility with existing copper infrastructure.

Suitable for

• Short-distance 10G Ethernet links between switches in data centers
• Server to switch connections where copper cabling is already installed
• Upgrading access or aggregation ports to 10G without fiber deployment
• Temporary 10G links for testing, staging or maintenance

Key specifications

• Interface: RJ-45 copper SFP
• Data rate: 10 Gbit/s (10G Ethernet)
• Maximum reach: up to 80 m over Cat6a/Cat7 structured cabling
• Form factor: SFP (small form-factor pluggable)
• Media: Twisted-pair copper (shielded or unshielded, use appropriate cable type)
• Operating principle: Electrical 10GBASE-T connectivity for short links

How to use

Insert the SFP transceiver into a compatible SFP/SFP+ port on your switch, router or server while the device is powered on or off as supported by the host (hot-pluggable). Connect a Cat6a or Cat7 RJ-45 cable between the transceiver and the remote device. Ensure both ends negotiate at 10G speed and verify link status via the host device management interface. If required, configure network settings on the connected devices to enable 10G operation and monitor link health and error counters through standard network management tools.

Recommendations

Use high-quality Cat6a or Cat7 cabling and keep cable runs within the 80 m maximum to ensure reliable 10G performance. Verify SFP compatibility with the host device and update firmware or driver settings if link negotiation issues occur. For electromagnetic-sensitive environments, prefer shielded cabling and proper grounding.
