Product information

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.
