Copper Gigabit Transceiver CBO SF1G-T for 1 Gbps over copper Ethernet

CBO SF1G-T is a copper SFP transceiver engineered for 1 Gbps Ethernet over standard twisted-pair copper cabling. The module offers a compact, hot-pluggable form factor compatible with SFP ports on switches, routers and media converters. It provides an RJ-45 interface for simple connection to existing copper infrastructure and supports short-range links where fiber is not required. The transceiver is designed to enable flexible port upgrades and straightforward integration into managed and unmanaged network environments.

Advantages

The copper SFP transceiver delivers gigabit performance over copper with a small SFP footprint, minimizing space usage in network equipment. Hot-pluggable functionality allows installation and replacement without powering down the host device. Its RJ-45 interface supports automatic negotiation for 10/100/1000 Mbps speeds where applicable and simplifies migration scenarios by using familiar copper cabling. The design supports reliable electrical connectivity and interoperability with standard Ethernet hardware.

Suitable for

• Short-range 1 Gbps connections between switches and routers
• Upgrading SFP ports to copper without changing chassis
• Connecting media converters or patch panels to copper networks
• Temporary or test links where fiber deployment is impractical

Key specifications

• Interface: SFP form factor with RJ-45 copper port
• Data rate: 1 Gbps (Gigabit Ethernet)
• Medium: Unshielded or shielded twisted-pair copper cabling
• Link range: Short-range copper links (typical horizontal cabling distances)
• Hot-pluggable: Yes
• Auto-negotiation: Supported for standard Ethernet speeds where applicable

How to use

Insert the SFP transceiver into an available SFP port on a compatible switch, router or media converter until it seats firmly. Connect a standard RJ-45 Ethernet cable from the transceiver to the copper network endpoint. The host device should detect the module and negotiate link speed automatically if supported. Monitor link and port status via the host equipment management interface to confirm operation. To remove, power down the port if required by the host, then extract the module by its release mechanism.

Usage recommendations

Use certified twisted-pair copper cabling and follow category standards appropriate for gigabit operation (for example Cat5e or higher). Ensure the host device supports copper SFP transceivers and check compatibility lists when planning upgrades. Avoid excessive bending or strain on the Ethernet cable and maintain proper ventilation around network equipment to support reliable operation.
