Overview

The Monoprice 124376 Cat6A Ethernet Patch Cable is a 20-foot shielded network cable designed for high-performance 10 Gigabit Ethernet connections. Built with 26AWG stranded pure bare copper conductors, it delivers the signal integrity needed for demanding network environments while supporting Power over Ethernet applications safely. The shielded twisted pair (STP) construction adds a layer of protection against electromagnetic interference and alien crosstalk — a meaningful advantage over unshielded Cat6 cables, particularly in environments with dense cable runs or nearby electrical equipment.

Each end of the cable features an RJ45 connector with 50-micron gold-plated contacts that resist oxidation and ensure consistent electrical contact over repeated insertions. The snagless boot protects the locking tab from catching on other cables or rack hardware during installation and removal. Rated for 500MHz bandwidth, this cable meets Cat6A specifications for 10GBASE-T networking at distances up to 100 meters, making the 20-foot length well within its performance envelope for both residential and commercial network setups.

Pros & Cons

👍 Pros

  • Shielded twisted pair design minimizes crosstalk and electromagnetic interference for cleaner signal transmission.
  • Pure bare copper 26AWG conductors ensure reliable performance and safe PoE support.
  • 50-micron gold-plated RJ45 contacts resist corrosion and maintain a solid connection over time.
  • Snagless boot design prevents the locking tab from snagging during installation and cable management.
  • 500MHz bandwidth supports 10 Gigabit Ethernet at the full 20-foot length without performance degradation.

👎 Cons

  • STP cables require grounded equipment at both ends to realize the full shielding benefit.
  • At 26AWG, the conductors are thinner than the 23-24AWG used in some Cat6A cables, which may slightly increase signal attenuation on longer runs.
  • The 20-foot length may be more cable than needed for short desktop connections, creating excess to manage.
  • Shielded construction makes the cable slightly stiffer and thicker than unshielded alternatives.

Frequently Asked Questions

Cat6A supports bandwidth up to 500MHz compared to Cat6's 250MHz, and it can run 10 Gigabit Ethernet at the full 100-meter distance rather than being limited to 55 meters. This 20-foot cable can handle 10GBASE-T without any distance concerns.
The STP shielding reduces electromagnetic interference and alien crosstalk between cable pairs, which is especially important at Cat6A speeds and in environments with nearby power cables or electronic equipment.
Yes, the RJ45 connectors with 50-micron gold-plated contacts are fully compatible with all standard Ethernet ports on switches, routers, computers, and other network equipment.
Yes, the pure bare copper conductors safely support PoE and PoE+ applications, providing reliable power delivery along with data transmission.
