SFP-10G-RJ45 10 Gbps Copper SFP+ Transceiver, CBO, compatible

The BlueOptics compatible SFP-10G-RJ45 10 Gbps Copper SFP+ Transceiver is a compact, hot-pluggable module that provides 10 Gigabit Ethernet connectivity over standard twisted-pair copper cabling via an RJ45 connector. Designed for insertion into SFP+ ports on switches, servers and network appliances, this transceiver enables copper-based 10 Gbps links without the need for fiber optics. It is suitable for short-reach links within racks, between adjacent racks, or between equipment in the same room where Cat6a/Cat7 cabling is available.

Advantages

This SFP+ copper transceiver delivers 10 Gbps throughput while using familiar copper cabling and RJ45 connectors, simplifying upgrades from 1 G to 10 G without replacing structured cabling in many environments. The module is hot-pluggable for easy installation and maintenance, and its compact SFP+ form factor conserves port density on network devices. Compatibility with standard SFP+ interfaces reduces interoperability issues and makes it a practical option for server uplinks, aggregation links and top-of-rack connections.

Suitable for

• 10 Gbps uplinks between servers and switches
• Switch-to-switch interconnects within the same room or rack
• Top-of-rack connections in data centers using Cat6a/Cat7
• Network equipment upgrades from 1 G to 10 G where copper is preferred

Key specifications

• Form factor: SFP+ (10 Gbps)
• Interface: RJ45 copper, full duplex Ethernet
• Data rate: 10 Gigabit Ethernet
• Cable type: Twisted-pair copper (Cat6a/Cat7 recommended for 10 Gbps)
• Reach: Short-reach copper links (dependent on cabling quality and environment)
• Hot-pluggable: Yes
• Operating temperature range: typical commercial range (device-specific details from host may apply)

How to use

Insert the SFP-10G-RJ45 transceiver into an empty SFP+ port on a compatible switch, server NIC or network appliance until it clicks into place. Connect a suitable RJ45 patch cable to the transceiver and the remote device, ensuring the cable meets category requirements for 10 Gbps. Configure the host device port settings as required (autonegotiation or fixed speed/duplex depending on the platform) and verify link status in the device management interface. For hot-swap operations, ensure network traffic is rerouted or maintenance windows are observed if needed.

Recommendations

Use Cat6a or Cat7 cabling for reliable 10 Gbps performance and keep copper cable runs short for best signal quality. Verify SFP+ compatibility with your specific switch or NIC model and consult the device vendor documentation for any required firmware or configuration settings. For critical links, test throughput and latency after installation and monitor temperature and link stability in continuous operation.
