Modular coupler RJ-45 ACT AC4105 White Connector 1 RJ-45 Connector 2 RJ-45

The ACT AC4105 modular RJ-45 coupler is a compact inline adapter with two RJ-45 connectors designed to join or extend Ethernet cables. Its white finish fits home and office environments and provides a simple way to continue existing network runs without reterminating cables.

Advantages

The coupler delivers a straightforward mechanical connection between two RJ-45 terminated cables, preserving signal continuity and avoiding the need to replace or re-crimp existing cables. Its compact, tool-free design allows quick installation and minimal footprint in patching or cabling scenarios.

Suitable for

• Extending Ethernet patch cables temporarily or permanently
• Joining two pre-terminated network cables without tools
• Home and small office network setups where additional cable length is needed

How to use

Insert the RJ-45 plug of the first cable firmly into one end of the coupler and insert the second cable’s RJ-45 plug into the opposite end until both clicks engage. Verify the network link is established by checking device link/activity indicators or using network testing tools if available. No special tools or termination are required.

Recommendations

For best performance, use the coupler with cables of the same category (e.g., Cat5e or Cat6) and avoid placing the inline connection in high-tension or moisture-prone locations. Limit the number of sequential couplers to minimize insertion loss and maintain signal quality.
