Overview

The Monoprice 107285 Cat5e RJ45 Inline Coupler is a keystone-style jack that joins two RJ45 patch cables back to back. It provides a straightforward way to extend cable runs, connect cables through wall plates, or link patch cords in a structured cabling setup—all without cutting wires or crimping new connectors. The keystone form factor means it clicks directly into standard keystone-compatible wall plates, surface-mount boxes, and blank patch panels, keeping installations tidy and organized.

Built as an unshielded coupler rated for Cat5e performance, it supports network speeds up to 1 Gbps and frequencies up to 100 MHz. The black housing blends into most wall plates and equipment racks. While it is not designed for high-performance Cat6 or Cat6a infrastructure, it serves its intended purpose well for home networks, small office setups, and anywhere a quick, reliable RJ45 cable connection is needed without the hassle of retermination.

Pros & Cons

👍 Pros

  • Keystone form factor snaps into standard wall plates, patch panels, and surface-mount boxes for clean installations.
  • Eliminates the need to splice or re-terminate cables when extending a network run.
  • Compact and low-profile design takes up minimal space inside a wall plate or panel.
  • Simple plug-and-play connection requires no tools or special expertise.

👎 Cons

  • Unshielded design offers no protection against electromagnetic interference in noisy environments.
  • Rated for Cat5e only, which limits maximum throughput to 1 Gbps and may not suit higher-speed networks.
  • Adding a coupler introduces an extra connection point that can slightly increase signal degradation on longer runs.
  • Sold as a single unit, so outfitting a full patch panel requires purchasing multiple couplers individually.
