Overview

The Monoprice 102139 is a 7-foot Cat5e Ethernet patch cable designed for short-distance wired connections — the kind of everyday link between a computer and a desk switch, a router and a modem, or a gaming console and a wall jack. Despite its low price, it is built with pure bare copper 24AWG wire rather than the copper-clad aluminum found in many budget cables. That distinction matters for signal quality and longevity, particularly in setups where cables stay connected for years. The 350MHz bandwidth rating supports full Gigabit Ethernet, which remains more than adequate for the vast majority of home and small office networks.

Monoprice has included practical details that make this cable easy to live with. The 50-micron gold plated RJ45 connectors resist the oxidation that can degrade connections over time, while the snagless strain relief boots protect the locking tabs from snapping off — a common annoyance with cheaper cables. The cable also meets TIA-568-C.2 and UL Code 444 standards, confirming it has been manufactured and tested to industry specifications. At 7 feet, it is purpose-built for local connections and keeps cable clutter to a minimum. For anyone building out a tidy desk setup or patching a few devices in a network closet, this cable delivers reliable Gigabit performance without any waste in length or budget.

Pros & Cons

👍 Pros

  • Pure bare copper conductors provide better signal quality and durability than copper-clad aluminum
  • 50-micron gold plated connectors resist corrosion for long-term reliable contact
  • Snagless boots prevent tab breakage and cable tangling in tight spaces
  • Meets TIA-568-C.2 and UL Code 444 compliance standards
  • Extremely affordable for a standards-compliant, pure copper cable

👎 Cons

  • At 7 feet, the length is only suitable for short, local connections
  • Cat5e tops out at 1Gbps and will not support 10Gbps networking
  • Unshielded design provides no protection from electromagnetic interference near power cables or motors
  • Black color may be difficult to see and trace in dark cable runs or behind equipment

Frequently Asked Questions

This is a patch cable using 24AWG bare copper conductors, designed for flexible, short-distance connections between devices and wall ports or switches.
Yes, as a Cat5e cable rated at 350MHz, it supports speeds up to 1Gbps, which covers Gigabit Ethernet.
The snagless strain relief boot covers the RJ45 locking tab so it does not catch on other cables, ports, or surfaces when you insert or remove it — especially useful in crowded patch panels.
Seven feet covers roughly the distance across a standard desk or from a desk to a nearby router or wall jack. Measure your specific run before purchasing to make sure.
Yes, it complies with UL Code 444, the National Electrical Code, and TIA-568-C.2 standards.
