Best Network Cable Testers Buying Guide
Before choosing the best network cable tester you should consider following options:
1. Cable type: The first thing you need to know is what type of cable you are testing. There are two main types:
Fiber optic: This is made up of a core of glass or plastic that is surrounded by a coating of strength members, known as a jacket.
Coated: Also known as ‘twisted pair’ cable, this is made up of two copper wires that are surrounded by a plastic coating.
Different types of cable will require different testing methods. For example, with fiber optic cables you will need to use an OTDR (optical time domain reflectometer) while with coated cables you might use a TDR (time domain reflectometer).
2. Cable length: The length of cable you are testing will also have an effect on the test you are doing. A longer length of cable will produce a lower reflected signal than a shorter length.
This means you will need to adjust your settings accordingly.
3. Cable condition: It is important to know the condition of the cable you are testing. If it is damaged it won’t produce a good reflection.
The cable tester should be able to recognize this and give you a warning.
4. Test speed: It is important to know how long the test will take. The speed at which the test is conducted will depend on the type of cable and the length of the cable.
Coated cables will generally produce a quicker result than fiber optic cables.
5. Cost: There are different types of cable testers available, with varying prices. You will also need to take into account the costs of additional equipment if required.
6. Accessories: The type of accessories the tester comes with will also have an impact on its cost. Some testers come with all the accessories you need, while others require you to purchase additional pieces of equipment.
7. Detection method: There are two main detection methods: bridge and ratio.
With the bridge detection method, the tester produces a reference signal and then compares it to the reflected signal.
With the ratio detection method, the tester produces a reference and reflected signal, then measures the ratio between the two signals.
8. Standards: It is important to know which standards your cable tester supports. Not all testers support the same standards, so it is important that your tester supports the standards you require.
9. Warranty: The warranty period will determine the quality of the product. If the manufacturer offers a short warranty period, chances are the quality of the product is low and it won’t last for very long.
10. Customer support: It is important to know what kind of support you will get from the manufacturer. The best way to do this is to read customer reviews, as well as looking at the length of warranty.

There are many different network cable testers on the market, and it really depends on your specific needs as to what is the best fit for you. If you need a basic cable tester that just tests for continuity, then a simple multimeter can suffice. If you need a more advanced tester that can test for crosstalk, wire map, and length, then you may want to consider a tester from a company like Fluke Networks.
2. What features do cable testers offer?
Some cable testers offer features such as the ability to test for continuity, the ability to test for proper wiring, the ability to test for AC or DC voltage, the ability to test for signal strength, and the ability to test for interference.
3. How do cable testers work?
A cable tester is a device used to verify the electrical connections in a cable or other wired assembly. A basic cable tester consists of a voltmeter, ammeter, and series of test leads with alligator clips.
4. What are the benefits of using a cable tester?
The benefits of using a cable tester are that it can help to ensure that the cables are correctly connected, it can help to identify any faults in the cables, and it can help to improve the performance of the system.
5. How do I choose the right cable tester for my needs?
There are a few considerations you should take into account when choosing a cable tester:
1. What type of cables do you need to test? There are different testers for different types of cables, so you’ll need to make sure you get a tester that’s compatible with the cables you need to test.
2. How many cables do you need to test at a time? Some testers can only test one cable at a time, while others can test multiple cables simultaneously.
3. How much detail do you need? Some testers will only tell you if a cable is working or not, while others will give you more detailed information about the cable, such as the length, wire gauge, and so on.
4. What features do you need? Some testers come with additional features, such as the ability to store test results, print them out, or connect to a computer.
