Modular Coupler RJ45 TF‑SO8/SO8/S Cat5e 8P8C — inline shielded coupler for Ethernet

Modular RJ45 coupler TF‑SO8/SO8/S is an inline shielded adapter for Cat5e 8P8C Ethernet connections that joins two patch cables. The coupler features a real metal housing and a metal-shrouded socket with an internal PCB board, providing a straightforward plug-and-play connection that preserves Cat5e performance up to 100 MHz and maintains STP shielding continuity.

Advantages

The metal housing and metal shroud socket increase mechanical durability and ensure reliable shielding compared with metalized-plastic alternatives. A PCB inside the coupler provides stable 1:1 pin mapping between both RJ45 female ports. The compact inline design makes it suitable for tight spaces and temporary extensions without requiring tools.

Suitable for

• Extending Cat5e RJ45 patch cords
• Temporary or provisional Ethernet links
• Installations with limited space where a compact inline coupler is needed

Key specifications

• Connection 1: RJ45 female (8P8C)
• Connection 2: RJ45 female (8P8C)
• Shielding class: STP
• Category: CAT 5e
• Max. bandwidth: 100 MHz
• Pin out: 1:1
• Housing: real metal

How to use

Insert the RJ45 plug of the first patch cable into one female port and the second patch cable into the opposite port until each plug clicks into place. Ensure both connectors are fully seated to maintain shielding continuity through the metal shroud. The device is plug-and-play and requires no configuration or tools.

Usage recommendations

For best signal integrity, use the coupler with Cat5e shielded (STP) patch cords and avoid repeated disconnection cycles in high-stress environments. Check that cable shields are properly terminated to preserve STP effectiveness.
