Factors You Should Consider Before Buying a Best Network Cable Tester?

After going through all the reviews, you must be wondering which one to buy. This is where you need the help of a buying guide to learn the factors that matter the most when buying a network cable tester. Go through this buying guide, and it should help clear your confusion.

1. Compatibility 

Cable network testers are designed to support a particular type of cable. And, this is why it is important to consider the type of cables you are working with.

Once you know the cable type, you can check out the best testers within your price range. You need to choose a tester that supports all cables you need to test. But this is for the home purpose only.

Professionals need a tester that works with all or most of the cables. This is because they have to work with different types of cables at different workplaces. 

Before getting a network cable tester make sure to check the type of cables it supports.

2. Type of Testing

A cable network tester can be used for multiple testing in your cable network. But when it comes to buying a tester, it is important to consider the type of testing it can perform. Because, if your tester doesn’t support the testing you want to perform, there’s no point buying it.

The different tests performed by a network tester include voltage check, continuity check, checking the connection, pin testing, measuring the length of the cable, and locating the port of the cable.

You must get a tester based on the type of testing you want to perform. If you want a tester for professional network testing, you should get a tester that supports multiple types of testing.

3. Length of the Cable 

Network testers are also used for measuring the length of cables without you moving through the entire length of cable. So before making your final call, you must check the maximum length of cable the tester can measure.

Most testers have a measuring capacity of 300m to 1km in 3-5 seconds. The price of a tester increases if it can measure cables longer than 300m.

4. LED/LCD Display

Most network testers have display screens to show results. But you will also find testers without a display screen. This type of tester shows you the results in the form of light or sound indicators.

For convenience, you should go for testers that have a display screen. This will make working with your tester easier. Also, a display-type tester is more efficient when it comes to measuring measure the length or voltage of a cable line.

However, you should know that the price of display-type testers is slightly higher than non-display testers.

5. LED Indicators & Speaker

When buying a network tester, you must also check whether the tool has an LED indicator or speaker. These two features are very important for a tester for obvious reasons.

Whenever you test a cable, you get notified by the speaker or light indicator or sometimes both. This helps you to know that testing is done, and you can see the results.

This ensures that you get accurate results at the correct time. Having these two features makes a tester more efficient to work with.

6. Warranty 

Network testers are electronic devices and they are most prone to malfunctioning. This is especially true when you are using your tool in extreme conditions more often. Hence it becomes important to check the warranty of the product.

Having a warranty ensures that the manufacturer will rectify the issue if your device malfunctions within the warranty period. You can either get it repaired or replaced without any extra charges. So it will be wise to look for testers that come with long warranty periods.

7. Price

Last but not least; you must also consider the price of the tool. A higher price ensures durability, performance, and features. If you want a quality tester, you shouldn’t shy away from shelling out a few extra bucks.

Buying a high-quality tester at a good price ensures that it will run longer, so you don’t need to spend money to repair it.

However, you shouldn’t spend a lot of money on unnecessary features that you don’t require. You should select a tester based on your requirements. Find your aspect and then select a tester that is most economical for you.

Type of Network Cable Testers

Network cable testers are equipped with a variety of features. They vary in terms of application, performance, and price.

Depending on the task, a network tester can be classified into three main groups, including certification, verification, and qualification.

Before you set out to purchase a network tester tool for your work, you should get an idea about the different types or groups of testers.

1. Cable Certification Testers

This type of tester provides “Pass” or “Fail” information in compliance with industry cabling standards. It is used to determine whether a link is compliant with a class (ISO) or category (TIA).

Cabling manufacturers need datacom installers to use certification testers to validate that the cable complies with the required cabling standards. It is the final step required to grant warranties for the installation of a new cable.

2. Cable Verification Testers

This type of tester is used to verify whether the cable is properly connected or not. In other words, it is used for basic continuity functions. It helps you to confirm that all cables are connected to the correct termination points.

It twisted pair cabling, it becomes difficult to maintain proper pairing of the cables. But with the help of verification testers, you can verify wire pairing and identify installation defects, such as split pairs.

Verification testers also help you to find a cabling link by providing a toner. Some verification testers include additional features like a Time Domain Reflectometer that helps you to determine the length of a cable. However, it doesn’t provide any bandwidth information.

3. Cable Qualification Testers

Qualification tools help you determine if an existing cabling link can work with certain network technologies and speeds. It comes in handy for technicians who don’t want to install new cabling and troubleshoot operating networks.

Qualification testers carry out tests that help you to know whether an existing cabling link is compatible with Fast Ethernet, Gigabit Ethernet, or Voice over Internet Protocol. You can also use it to quickly separate cabling issues from network protocols.

Some qualification testers include all the capabilities of verification tools. However, qualification testers are more powerful as they can assess the cabling bandwidth and identify the defects that are affecting it.

How to Use a Network Cable Tester?

If you are using a network cable tester for the first time, you might it a little intimidating. But no worries, we have got your back.

Here’s what you need to do:

1. Connect the Network Tester

The first thing you need to do is connect the tester by plugging one end of the network cable into the receiver, and the other end into the transmitter. Before proceeding to the next step make sure that the cables are properly plugged in.

2. Turn on the Network Tester

Now power on the tester. It will send a signal down the cable. You will have to make sure that the cable is connected at all times during the test. If the cable becomes loose, it will not work.

3. Read the Report

While the signal is passed down from one end to the other end of the cable, the tester will examine the message for faults. It will also check whether the message is properly delivered to the other end. If it doesn’t happen the way it should, the tester will show you red lights. However, if the message is received properly by the other end, you will be shown green lights.

4. Read the Problem

Your tester has different light indicators for a reason. It shows different patterns to indicate different things. You should take the help of the manual guide to understand what the lights or different light patterns indicate. Once you identify the problem, remove the cable from the boxes, and keep the tester in a safe place.
