## Summary description

SOMI Networks SFPIRJ451G is a copper SFP transceiver with an RJ45 connector supporting 10/100/1000 Mbps Ethernet. It plugs into SFP slots on switches, routers and media converters to provide Gigabit copper connectivity without fiber. The module is suited for network upgrades, spare replacements and mixed media deployments, offering plug-and-play installation and compact compatibility with standard SFP ports.

## Long description

SOMI Networks SFP transceiver SFPIRJ451G is a compact copper SFP module with an RJ45 connector that provides 10/100/1000 Mbps Ethernet over standard twisted-pair copper cabling. Designed to fit into SFP slots on switches, routers and media converters, this module enables Gigabit copper connectivity where fiber links are not required or available. The module supports auto-negotiation for speed and duplex, and is compatible with equipment that accepts standard SFP form-factor copper transceivers, making it suitable for network topology changes, equipment upgrades and service replacements.
Advantages
The SFPIRJ451G offers a space-saving alternative to standalone RJ45 ports by occupying a single SFP slot while delivering Gigabit copper performance. It allows quick, plug-and-play replacement or addition of copper interfaces without modifying chassis or backplanes. The module supports broad interoperability with SFP-enabled devices and reduces the need for separate external converters, simplifying rack and cable management.
Suitable for
Adding or replacing copper Gigabit ports in switches and routers
Temporary connections for testing and diagnostics in server rooms and wiring closets
Mixed media deployments where some links remain copper and others use fiber
Network upgrades where short-distance copper is preferred over fiber
Key specifications
Connector type: RJ45 (8P8C) for Cat5e/Cat6 twisted-pair cabling
Data rates supported: 10 / 100 / 1000 Mbps with auto-negotiation
Form factor: Small Form-Factor Pluggable (SFP) module
Duplex: Half and full duplex support where applicable; auto MDI/MDIX
Operating temperature range: standard commercial grade
Power consumption: low-power SFP class device
How to use
Insert the SFPIRJ451G module into an empty SFP slot on a compatible switch, router or media converter until it clicks into place. Connect a standard Ethernet cable (Cat5e or better) between the module's RJ45 port and the network device or endpoint. The host device should detect the module and negotiate link speed and duplex automatically; verify link lights and management interfaces to confirm connectivity. To remove the module, power down or follow hot-swap procedures recommended by the host device, then press the module's release mechanism and gently withdraw it.
Usage recommendations
Use Cat5e or Cat6 cables for reliable Gigabit performance and keep copper link lengths within standard Ethernet limits (up to 100 meters) for optimal signal integrity. Verify host equipment compatibility with standard SFP copper modules before deployment and follow ESD precautions during installation.
