We have compiled a comprehensive review of the top 10 products in the market to help you out. Continue reading this article to get more information about these products.

Product Guide

The requirements for cable infrastructure has been rapidly evolving along with network systems. As a result, new guidelines for cabling standards for both tech users and cabling professionals when certifying, installing, troubleshooting, and testing either fiber or copper networks are introduced.

This is why the best network testing tools are necessary. These testers will help you quickly identify whether your cables are working properly and whether they are up to the standards set by local authorities.

The best network cable tester varies in features and application. However, it is mainly classified into these three hierarchical groups:

i) Cable Certification Testers

Cabling professionals typically use cable certification tester devices. It helps assess whether the cabling system complies with the industry standards. This device indicates whether the cabling system “pass” or “fail. This can of testing ensures that newly installed cable links will support the transmission speed you intend to have.

 ii) Cable Qualification Testers

These best cable tester indicate whether an existing cabling link can support particular technologies or network speeds. Many cabling professionals also use these types of testers to identify existing cables that can support the requirements for Voice over Internet Protocol (VoIP), Gigabit Ethernet, or Fast Ethernet.

iii) Cable Verification Testers

The main function of these types of testers is to verify whether the cabling system is properly connected. It performs basic continuity functions and ensures that all the wires are properly connected to the appropriate termination points.

Buying Guide: What to Consider When Choose Network Cable Tester

Network Cable Tester

We have listed the top 10 best network tester in the market. The question now is, which one is the best option for you? To prevent confusions, here are some essential factors that will help you determine what product you should buy:

a) Type of Testing

As mentioned above, there are several types of cable network testing; hence network testers also vary in function. The first thing that you have to figure out when buying your very own network cable tester is to identify what type of specific testing you intend to perform.

These different types of testing can either be checking proper connectivity, locating cable port location, pin testing, measuring cable length, voltage checking, or doing continuity check.

Suppose you are an amateur user who simply wants to ensure that your home cables are working properly. In that case, you can just pick testers that have cable length measuring, connectivity checking, and locating cable port location functions.

However, if you are a professional, you would want your tester to have multiple functions since you will need to do different types of testing from time to time. And we need to know how to use a network cable tester.

Also, note that if you intend to do PoE testing, make sure that the device you will use will not be fried by the cable or port’s voltage.

b) Cable Compatibility

Knowing that each network line tester is designed for a particular type of wire or cable is crucial. This is why you must know what type of wires you have in your networking panel. These wires can either be twisted pair cables, optical fiber cables, or coaxial cables. After you figure out the type of wires that you will be testing, it is easy for you to find which LAN cable tester to choose from.

If you are a cabling professional, you will want your cable tester to support almost all types of wires out there because you will be testing different varieties of wires at different job sites.

However, these types of testers can be a little bit more expensive because they have more functions. To be safe, ensure that you have a network cable tester that is compatible with coaxial cables because that is the most common type of wire used in the industry.

c) Tester Display

Standard networking testers only show results by using sounds or light indicators. These types of network testers tend to be very affordable.

However, the downside is that if you are in a noisy environment or are not well-versed with the meaning of the sounds and light indicator, you might struggle to read the results, which can affect your efficiency and accuracy.

On the other hand, higher-end network cable testers mostly have display screens. These displays are either small LCD or LED monitors that indicate the result of each test that you run. These are more foolproof compared to light and sound indicators.

Furthermore, if you intend to be doing voltage testing or identify the length of a cable, you should definitely opt for network cable testers with LCD or LED displays.

However, since cable testers with LCD or LED displays have more features, functions, and convenience, expect it to be more expensive compared to standard cable testers. But, if you are a cabling professional, you will definitely get the highest benefits when you invest in a higher-end model.

d) Warranty

When you buy an electronic gadget, it is good to opt for a manufacturer who offers some sort of warranty for their product. This shows you that the company is confident in their product, and they have after-sales accountability.

Furthermore, by opting for a company that offers a warranty, the money you invest in the device can be protected if you experience any problem or malfunction. However, it is important to pay close attention to the stipulation of the company’s warranty.

e) Price

Another important consideration when buying a network cable tester is the price. You need to pick one that has value for money and fits your needs and requirements.

When assessing whether a network cable tester has value for money, the rule of thumb is to look at its features and functions relative to its price. The more features and functions there are, the higher the price will be.

If you are a cabling professional, it is a fair trade-off to pay for more money, given that you will get more features and functions because you will be utilizing them almost every day for your job.

However, suppose you are a homeowner who simply wants to troubleshoot or double-check whether the cables on your home network are functioning well. In that case, the basic models that do the job will give you the best value.

Final Words

There are indeed plenty of great options for the best network cable tester in the market today. However, to make it easy for you to pick the best, always go for what you can afford that fits your needs and requirements.

The product mentioned above provides various options for different levels of needs, so you will surely find one that fits your requirements. Besides, if you have some doubts, just refer to the buying guide in this article to get the information you need.
