It converts or extends RJ-45 connections without altering wiring, suitable for network patching, linking Ethernet cables, and temporary adjustments in LAN setups.

## Long description

EFB Elektronik 37489.1 is a passive RJ-45 to RJ-45 cable gender changer in a bronze metal housing. Designed for copper Ethernet cabling, the adapter provides a straight 1:1 connection between two RJ-45 patch cables without altering wiring or signal mapping. The unit supports shielded connectors and is suitable for Category 6 patching and short links where a compact, durable female-to-female adapter is needed.
Advantages
The adapter features two shielded RJ-45 connectors in a robust metal housing that provides mechanical protection and helps maintain cable shielding continuity. Its 1:1 allocation preserves original pair mapping and signal integrity, making it suitable for standard Ethernet use. The compact, passive design requires no power or configuration and offers a simple way to link or extend cables while minimizing additional points of failure.
Suitable for
Linking two Ethernet patch cables to extend reach
Temporary adjustments in LAN patch panels or server racks
Patching Category 6 copper cabling for office and home networks
Connecting shielded cables where continuity of shielding is required
Key specifications
Connector type: RJ-45 female to RJ-45 female
Cable category support: Cat.6
Shielding: shielded connectors and metal housing
Contact mapping: straight-through 1:1 allocation

How to use
Insert the RJ-45 plug of the first patch cable into one side of the adapter and the RJ-45 plug of the second patch cable into the opposite side until both connectors latch. Verify that connections are secure and that cable shielding is engaged if using shielded cables. After connecting, test the link with network testing tools or by confirming device network connectivity to ensure signal integrity and correct wiring continuity.
Usage recommendations
Use the adapter for short-term extensions or temporary cable linking; minimize use in permanent installations where a single continuous cable or proper panel termination is preferred. Ensure shielded cable pairs are properly grounded when maintaining shielding continuity through the adapter.
