## Summary description

Copper SFP (mini-GBIC) transceiver Cisco SFPCRJ451GG provides RJ45 Gigabit Ethernet connectivity at 10/100/1000 Mbps over standard copper cabling with a maximum transfer distance of 100 m. Designed for hot-pluggable use in compatible SFP slots, it enables network uplinks, switch-to-switch links and server connections where copper Gigabit ports are required.

## Long description

The Cisco SFPCRJ451GG is a copper SFP (mini-GBIC) transceiver module that provides a standard RJ45 Gigabit Ethernet interface at 10/100/1000 Mbps. Intended for installation in compatible SFP slots, the module supports hot-pluggable operation and enables short-distance copper connections over existing twisted-pair cabling with a maximum reach of up to 100 meters. It is suitable for creating uplinks, switch-to-switch links and server connections where a copper Gigabit interface is required.
Advantages
This RJ45 10/100/1000 Mbps copper SFP offers a compact, hot-swappable form factor that preserves SFP slot flexibility while adding a copper Ethernet port. It supports auto-negotiation across common Ethernet speeds, allowing compatibility with a wide range of network devices. The module uses standard twisted-pair cabling and provides a straightforward, low-latency connection for local networking tasks without requiring fiber optics.
Suitable for
Switch-to-switch uplinks within a data center or wiring closet
Server connections to switches when copper Gigabit ports are needed
Edge and access layer links where fiber is not available or necessary
Temporary or emergency copper links during network maintenance or upgrades
Key specifications
Interface: RJ45 copper Ethernet
Data rates: 10/100/1000 Mbps (auto-negotiation)
Form factor: SFP (mini-GBIC), hot-pluggable
Cable type: Cat5e/Cat6 twisted-pair copper cabling
Maximum link distance: up to 100 meters over suitable twisted-pair cable
Transmission medium: 1000BASE-T / 100BASE-TX / 10BASE-T
How to use
Insert the transceiver into a compatible SFP port on a switch, router or network interface card while the host device is powered on or off, following the equipment manufacturer's hot-plug guidance. Connect a standard RJ45 patch cable from the module to the remote device. Ensure both ends have compatible speed and duplex settings or allow auto-negotiation to determine optimal link parameters. Monitor the host device port status and system logs to confirm link establishment.
Usage recommendations
Use Category-rated twisted-pair cabling (Cat5e or Cat6) in good condition to achieve reliable 100 m Gigabit links. Avoid using damaged or poorly terminated cables, and verify switch software compatibility and supported transceiver lists where applicable to ensure full interoperability.
