SFP Module Extralink SFP RJ45 10G 1x RJ45 10Gb/s Copper

The Extralink SFP RJ45 10G is a copper SFP transceiver designed for 10 Gb/s Ethernet connections over standard twisted-pair copper cabling. Housed in a durable silver aluminum enclosure, this small form-factor pluggable (SFP+) module provides an RJ-45 interface and supports a maximum data transfer rate of 10000 Mbit/s, making it suitable for integration into switches, routers and other networking equipment with compatible SFP+ ports.

Advantages

This SFP module combines a compact SFP+ form factor with a familiar RJ-45 copper connection, allowing easy migration from fiber to copper links where short-distance 10G connectivity is required. The aluminum housing offers mechanical protection and improved heat dissipation. The module’s support for up to 10 Gb/s ensures compatibility with high-throughput applications and modern network architectures that rely on SFP+ ports.

Suitable for

• Short-reach 10 Gigabit Ethernet links over Cat6/Cat6a cabling
• Upgrading switches or routers with SFP+ ports to support copper 10G connections
• Data center top-of-rack and aggregation connections within a single room or building
• Network equipment testing and lab environments requiring pluggable copper transceivers

Key specifications

• Interface: RJ-45 copper
• Maximum data transfer rate: 10000 Mbit/s (10 Gb/s)
• Form factor: SFP+ (small form-factor pluggable)
• Housing material and colour: silver aluminum enclosure
• Transmission medium: twisted-pair copper cable (Category-rated cabling)

How to use

Insert the Extralink SFP RJ45 10G into a compatible SFP+ port on a switch, router or network interface module while the host device is powered down or follows hot-plug guidelines from the equipment manufacturer. Connect an appropriate Category-rated copper cable (for example Cat6 or Cat6a) to the RJ-45 port on the module and to the corresponding port on the remote device. Configure link speed and duplex settings on the host device if necessary; most modern equipment will auto-negotiate 10 Gb/s when both ends support the speed.

Usage recommendations

Use high-quality Category-rated cabling and keep copper runs within recommended length limits for 10G over twisted-pair. Verify compatibility with your network equipment vendor and ensure firmware and driver support for SFP+ copper modules to achieve stable 10 Gb/s operation.
