What is a Network Cable Tester?

A network cable tester is a device used to determine the transmission capabilities of a network cable.

Network administrators rely heavily on network cable testers when they have to install a new cable or remove the inadequacies of installed cables. That’s why it is always advisable to learn the factors which will help you pick the best network cable tester and gather cable-related information easily.

These testers can give the professionals information about continuity, wire map, cable length, DC loop resistance, etc.

What is LAN Tester in Networking?

LAN cable tester is the most useful tool for network providers and technical administrators in offices and institutions.

It is a handheld device used by these people to identify continuity in connection, shorted pairs, crossovers, IP addresses, polarity as well as breakpoints. Different LAN testers can test optical fiber cables, ethernet cables, and even coaxial cables.

How To Test An Ethernet Cable With A Tester?

For testing your cable you can use a detachable ethernet tester, where the main tester works as a transmitter and the detachable part works as a receiver. Also, make sure the tester works for the length of the cable you are testing for.

Now first, you need to plug one end of the cable to the transmitter part and the other end of the cable to the receiver part of the tester using the RJ45 ports. Now on the basis of what type of tester you are using you will be able to test the cable by matching the flashing LEDs on both receiver and transmitter. Or you will see some sort of message on the screen in case you are using the tester with the display.

Different testers have different parameters to test the cables which you can understand by looking at their user guide. Here’s a video that shows how you can easily test your ethernet cables.

How To Know If The Network Cable Is Good or Not?

There are some signs that you can notice to tell whether your cable is working fine or not without using an ethernet tester. So the symptoms of bad Ethernet cables are:

1. Slow and Intermittent connection

If you are suddenly facing a decline in your internet speed or your experience a non-steady internet connection, then the chances are high that your network cable is not perfectly alright.

2. Failed Network Connection

Another possible sign that the ethernet cable is not working fine is that it fails to establish the network connection with the router. In such a case, either the router or the cable can be the culprit but if your try to establish a cable connection with another cable and if that happens successfully then it’s obvious that your network cable has gone bad.

3. Network Restores With A Wiggle

If you ever experience that the lost connection gets restored just by wiggling the cable then it means you are dealing with a broken cable.

However, to be sure that your cable is bad or not you should test it out using a good cable tester.

Factors To Consider Before Buying Best Network Cable Tester

Just like with any other product you need to keep some important factors in mind before buying a network tester. It will help you in picking up the right product for your use and saves you from wasting money on the wrong one.

Type Of Testers

As the name suggests these testers are used to verify if there’s any kind of fault in the cables or not. And these are also the most common type of cable tester you’ll see around.

The cable verifier testers tell you about whether the cables are connected properly or not, it also gives information about short circuits, split pairs, open wires, etc. So overall you can diagnose any kind of fault in your cables and wires using the verifier testers. However, this verification tester gives no information about data communication.

2. Cable Qualifiers: These testers have all features that a verifier tester has. But it has one more feature which is missing from the verifiers and that is it can tell about the type or kind of data transmission a given cable supports. Apart from finding faults, a cable qualifier can also assist you in repairing your existing cables.

3. Cable Certifiers: These are the most advanced cable testers which are mostly used by network technicians. The cable certifier comes with a lot of advanced features that are required to ensure the perfect installation of the cables.

Build Design And Quality

The tester basically comes in two designs, the handheld portable unit, and the detachable unit. The handheld tester is a single device or tool while the detachable modular unit has two parts to it. The secondary part gets detached from the main device to give you more freedom for testing.

Also, the detachable unit comes with more features therefore you will see most of the powerful tester come in a detachable build design. However, the portable units are easier to operate and handle.

Apart from this, you should also check the build quality of the tester, so that it doesn’t break easily upon falling from your hands. If you have butterfingers then you can go with a tester that comes with a holding strap.

Moreover, the tester should not be too heavy either so that you can easily operate it for a long time. Also if you are looking for a tester for outdoor usage then make sure your tester is waterproof or at least water-resistant.

Connector Compatibility

Network cables generally come with an RJ45 connector on both ends. So in order to test a network cable, your tester must have an RJ45 port. Apart from that, your tester should also support different ports like the coaxial connector, RJ11 port, and especially the SC/SFP for testing fiber optic cables. However, a network testing tool with an RJ45 and SC/SFP compatibility is sufficient enough to solve all the network-related issues.

Ease Of Use

Testing a network cable is a technical task, however, some testers make it easier for even a novice to understand the issue in their network cable by showing the readings in a simpler way. While some testers only show reading in raw data which can be only decoded or understood by a network technician. So, it is important that you pick an ethernet cable tester that is easy to use and understand.

Cable Length

The length of the network cable also plays a vital role while picking up a tester, as each tester has its own limitations. Some cable testers can only test shorter cables so you cannot use them to test long broadband lines. Thus, pick your tester wisely keeping your area of work in mind.

Final Thoughts On Network Cable Tester

A wired connection is a faster and more reliable way of network communication. However, unlike wireless connections, in a wired connection, we are always tethered by wires and cables. And no matter how good the cable is it is prone to damage due to various external and internal issues.

A damaged cable can severely affect the performance and speed of the connection so you should keep a good tester handy to easily check your cable for any faults and replace it as soon as possible to re-establish your connection.
