Describe the types of cable testers and their features
There are many types of cable testers on the market, but they all basically do the same job. They test the continuity of a cable and its wiring. The most common type of cable tester is the digital tester. It tests the continuity of a cable by measuring the resistance between two points on the cable. A digital tester will give you an accurate reading of how much resistance is in the cable. This type of tester is especially useful for troubleshooting problems with a network or computer system.

Another type of cable tester is an analog tester. This type of tester measures the voltage drop across a resistor in order to determine the resistance value. Analog testers are not as accurate as digital testers, but they are less expensive and more portable. The third type of cable tester is an optical power meter.

Types of Cable Testers and What They Check
| Tester type | What it checks | Best for |
|---|---|---|
| Continuity tester | Open or short circuits, correct wiring | Basic cable checks |
| Network cable tester | Wire map, length, faults in Ethernet cables | IT and network installs |
| Coaxial cable tester | Signal loss, shorts in coax cable | TV and satellite installs |
| Fiber optic tester | Light loss, breaks in fiber | Fiber networks |
| TDR tester | Distance to a fault along the cable | Long cable runs |
A cable tester checks whether a cable is wired correctly and whether it carries a signal. The most common type is the digital tester. It tests the continuity of a cable by measuring the resistance between two points on the cable. A digital tester will give you an accurate reading of how much resistance is in the cable. This type of tester is especially useful for troubleshooting problems with a network or computer system. An analog tester measures the voltage drop across a resistor to determine the resistance value. Analog testers are not as accurate as digital testers, but they are less expensive and more portable. A network cable tester checks the wire map of an Ethernet cable. It tells you if the wires are in the right order. It also checks for opens, shorts, and split pairs. A TDR (time domain reflectometer) sends a pulse down the cable and measures the time it takes to return. This tells you how far away a fault is. This is useful for long cable runs in buildings.
How to Test a Network Cable: Step by Step
Step one: plug one end of the cable into the main unit and the other end into the remote unit. Step two: turn on the tester. Step three: run the wire map test. The tester will show if each wire is connected to the right pin. Step four: check for opens and shorts. An open means a wire is broken. A short means two wires touch. Step five: check the cable length. Many testers show the length. A cable longer than 100 metres may fail for Ethernet use. Step six: test for split pairs. A split pair happens when wires from different pairs are crossed. It can cause crosstalk and slow speeds. Step seven: if the cable fails, check the connectors first. A bad crimp is the most common fault. Re-crimp the connector and test again. If the cable still fails, replace it. Always test a cable before you install it in a wall or ceiling. It is much harder to fix after installation.
Frequently Asked Questions
What does a cable tester do?
A cable tester checks whether a cable is wired correctly and whether it carries a signal. It can find opens, shorts, crossed wires, and split pairs. It helps technicians find faults fast.
What is the difference between a digital and an analog cable tester?
A digital tester gives an accurate reading of resistance and is useful for troubleshooting networks. An analog tester measures voltage drop and is less accurate, but it is cheaper and more portable.
How do I test a network cable?
Plug one end into the main unit and the other into the remote unit. Run the wire map test. Check for opens, shorts, and split pairs. Check the cable length. Re-crimp a bad connector and test again.
What is a TDR tester?
A TDR (time domain reflectometer) sends a pulse down the cable and measures the time it takes to return. This tells you how far away a fault is. It is useful for long cable runs in buildings.
How long can an Ethernet cable be?
An Ethernet cable should be no longer than 100 metres for reliable use. Longer cables can cause signal loss and slow speeds. Use a switch or repeater for longer runs.
