No name Łącznik RJ45-G/RJ45-G*P100 — RJ45 coupler, female-to-female

No name Łącznik RJ45-G/RJ45-G*P100 is an inline RJ45 coupler that joins two standard RJ45 patch cables with a female-to-female connection. Designed for Ethernet cabling, the coupler makes it possible to extend existing patch cords or link cables quickly without reterminating connectors. Its compact form factor allows installation in tight spaces and temporary setups while maintaining the original cable wiring and signal path.

Advantages

The RJ45 female-to-female coupler offers a simple mechanical solution to extend or repair network runs without tools. It supports a straightforward plug-and-play operation, preserving cable wiring and eliminating the need for crimping or soldering. The compact inline design minimizes additional footprint in cable channels and patch areas, and the standard modular housing provides compatibility with common Ethernet patch leads.

Suitable for (tasks / use cases)

• Extending a patch cable length in office or home LAN setups
• Temporary network links during maintenance or testing
• Quick on-site repairs where cable retermination is not feasible
• Connecting short runs between devices in patch panels or switch ports

Key specifications

• Connector type: RJ45 female-to-female modular coupler
• Compatible cable: standard Ethernet patch cords (8P8C modular plugs)
• Form factor: compact inline housing for minimal space usage
• Contact arrangement: pass-through connection maintaining original pinout
• Usage environment: indoor LAN installations, temporary and permanent patching

How to use

To use the coupler, align and insert each RJ45 plug fully into the female ends until the modular latches click into place. Ensure both cables are oriented consistently to maintain correct pinout and signal continuity. After connection, gently route cables to avoid sharp bends near the coupler and secure them if necessary to prevent strain on the modular plugs. For removal, depress the plug latch and pull the plug straight out to avoid damaging the connector.

Usage recommendations

Use the coupler for short-term extensions and repairs; while suitable for general Ethernet patching, cumulative connections can increase insertion loss and potential signal degradation. For permanent or high-performance runs, prefer a single continuous cable meeting category requirements. Keep the coupler away from moisture and extreme temperatures and avoid exposing it to mechanical stress or tension.
