## Description

An RJ45 Loopback r is an exceedingly user friendly cable r. Even the architecture is pretty simple. It looks like a simple plug at first glance but the compact, rugged design makes it highly portable and usable in the tightest corners. All you have to do is simply plug the Networx(tm) RJ45 loopback r into the jack that you want to test or the one you are suspicious about. If the link LED on your switch is active, then that means that the connection is operating perfectly.These Loop back rs will make the life of a network administrator really easy. The Networx(tm) RJ45 Loop back r will negate the necessity to carry a bulky network hub around.

Review: Despite the warnings from other buyers and the fact that it is made in China, I bought the device. Unsurprisingly it did not work. A refund is on the way. Hopefully that will work as it is made in the USA!
Review: Very Good product and works as it it intended for. Just make sure you get the right one for the job. The Gig loopback is different from the RJ45. Although technically both are RJ45 structure, the internal wiring is different. These loopback are great for Analyst remoting-in and conducting their own company proprietary test on their machines.

## Features

- Check wall to switch connections easily without a cable
- Easily check for broken or shorted wires
- Must have for all pc and network technicians
- Available in a Gigabit version

Having a reliable way to quickly to check for a port failure is a must. Doing a quick loopback test is a fast, easy way to check a port. I like the design of this device because all of the wires are tucked inside the body.
