SFP transceiver CBO SFP-10G-RJ45 10 Gbps RJ45 copper module

The BlueOptics CBO SFP-10G-RJ45 is a copper SFP+ transceiver module that delivers 10 Gbps Ethernet connectivity over standard RJ45 cabling. Designed for installation in SFP+ ports, this module enables short-reach 10 Gigabit links using Cat6a or Cat7 copper cable, making it compatible with switches, routers and servers that accept SFP+ form-factor modules. The unit provides plug-and-play functionality and hot-swappable operation to simplify network upgrades and maintenance without extended downtime.

Advantages

The transceiver supports 10 Gigabit data rates while using existing copper infrastructure, reducing the need for fiber in short-reach scenarios. Its SFP+ form factor offers broad compatibility with equipment that accepts SFP modules and allows flexible deployment in high-density network environments. The module’s hot-swappable design and plug-and-play operation make installation and replacement straightforward, minimizing service interruptions during hardware changes.

Suitable for

• Short-reach 10 Gbps links between switches and aggregation devices
• Server uplinks to 10G-capable switches in data centers or racks
• 10G connectivity over existing Cat6a or Cat7 copper cabling
• Network maintenance and incremental upgrades where fiber is not required

Key specifications

• Interface: SFP+ form factor with RJ45 copper port
• Nominal data rate: 10 Gbps
• Cable type: Compatible with Cat6a and Cat7 copper cabling for short-reach links
• Reach: Designed for short-reach connections over twisted-pair copper (typical up to 30–100 m depending on cable and environment)
• Operation: Hot-swappable, plug-and-play installation
• Media: 10 Gigabit Ethernet over copper

How to use

Insert the SFP-10G-RJ45 module into an available SFP+ slot on your switch, router or server until it clicks into place. Connect the RJ45 end to a compatible Cat6a or Cat7 copper cable, then attach the other cable end to the remote device. The module typically negotiates 10 Gbps operation automatically; verify link status and speed via the host device interface. To remove, power down the port if recommended by the equipment vendor or use the host device controls, then gently extract the module. Observe ESD precautions when handling the transceiver.

Usage recommendations

For reliable 10 Gbps performance, use high-quality Cat6a or Cat7 cables with proper shielding where required and ensure patch panels and connectors are rated for 10G operation. Check compatibility with the host device vendor and update firmware or drivers if necessary to ensure full feature support. Avoid exceeding the recommended cable length for copper 10G links to prevent signal degradation.
