Copper transceiver module BlueOptics 813874-B21-BO 10000 Mbit/s RJ-45

The BlueOptics 813874-B21-BO Copper transceiver module is a compact SFP+ unit designed for 10 Gbit/s copper Ethernet links via an RJ-45 interface. Weighing approximately 20 g and finished in silver, the module supports data rates up to 10000 Mbit/s and is intended for short-range connections up to 30 m over twisted pair cabling. The module follows MSA-compliant SFP+ form factor conventions to ensure physical and electrical interoperability with compatible network equipment.

Advantages

The module provides a standardized SFP+ copper interface for plug-and-play installation in compatible switches, routers and storage devices that accept 10GBASE-T SFP+ transceivers. It supports high-speed 10 Gbit/s transmission over existing twisted-pair copper cabling for short distances, enabling upgrades where fiber deployment is impractical. The small, lightweight design reduces space and weight in dense chassis environments while maintaining industrial compliance for interoperability.

Suitable for

• Short-distance 10 Gbit/s links over Cat6/Cat6a twisted-pair cabling (up to 30 m)
• Upgrading switch or router ports to 10GBASE-T where an RJ-45 SFP+ slot is available
• Server to switch connections in data center top-of-rack environments
• Network equipment test setups and lab environments requiring 10G copper transceivers

Key specifications

• Maximum transfer distance: 30 m on twisted-pair copper
• Interface: RJ-45 connector for copper cabling
• Form factor: SFP+ (MSA-compliant)
• Weight: 0.02 kg
• Product colour: Silver

How to use

Install the transceiver into a compatible SFP+ slot on your network device until it seats firmly, then connect a suitable RJ-45 terminated twisted-pair cable (Cat6/Cat6a recommended) between the module and the remote port. Ensure the host device firmware or software supports 10GBASE-T SFP+ modules. After installation, verify link status and negotiated speed through the device management interface or CLI. For reliable performance, use cables and patch panels rated for 10 Gbit/s and keep the cable length within the specified 30 m limit.

Recommendations

Use this module for short-range 10G copper connections where fibre is not available or cost-effective. Verify hardware compatibility and enable any required firmware settings on the host device to ensure full functionality and, if supported, access digital diagnostic monitoring features provided by the platform.
