LAN cable testers, or SCMA Lan cable testers, are specialized testing devices designed to check the integrity and functionality of network cables such as Cat5, Cat6, and other LAN cable types. These tools are crucial for network professionals as they accurately and quickly identify signal line issues.
What is a LAN Cable Tester?
LAN cable tester (test cable) is a tool used to test the strength of signals and connections in network cables, LAN network cables, telephone lines, and other signal lines. This LAN testing device can verify if the installation is correct and measure the signal strength between the source and destination. Typically, it consists of a main unit (main unit) and a remote unit (remote unit) that work together to analyze connection quality and accuracy.
What are the Benefits of Using a LAN Cable Tester?
LAN cable tester helps technicians and network administrators work more efficiently by testing whether signal lines, LAN network cables (Lan network cable), telephone lines are installed correctly and checking the signal strength between the source and destination. It aids in quickly diagnosing and resolving connection issues such as finding broken points, short circuits, or incorrect connections. Additionally, it saves time and maintenance costs due to its precise problem identification without having to check the entire system.
What are the features of a LAN cable tester?
A LAN test device is a versatile tool that varies in complexity and price, ranging from basic models to professional ones. Generally, it is a portable handheld unit powered by batteries, equipped with a microcontroller and display screen for automatic testing and result presentation.
Standard models typically consist of the main unit and remote units, featuring RJ45 ports for LAN cables and RJ11 ports for telephone lines. Higher-end models like TIS 880 can test various types of cables including coaxial cable, unshielded twisted pair (UTP), and shielded twisted pair (STP) with precise pinpointing of specific issues.
Professional LAN cable testers also offer advanced functions such as measuring cable length, locating breaks or short circuits in the line, testing for signal interference, and comprehensive signal quality analysis. This enables technicians to efficiently diagnose and resolve network issues.
What is the difference between a LAN cable tester and a multimeter?
A LAN cable tester and a multimeter are testing devices that differ in both design and intended use. A non-contact voltage detector only detects whether there is live voltage present, while the two tools have different measurement capabilities suited for different tasks as detailed below.
LAN Cable Tester
A LAN cable tester is specifically designed to analyze network cables. It has the ability to check each individual wire connection within an RJ45 connector, detect shorts, breaks in wires, and wiring sequence errors. Additionally, it can identify specific network issues such as split pairs, crosstalk, and evaluate signal transmission quality according to TIA/EIA standards.
Multimeter
A multimeter is a versatile electrical measurement tool that can measure various values such as voltage, current, resistance, circuit continuity, and other electrical parameters. Although it can check for wire continuity, it cannot analyze the wiring sequence in an RJ45 connector or specific network system issues, making it more suitable for general electrical work rather than network tasks.
How to Use a LAN Cable Tester
Testing network cables with a LAN cable tester is not complicated, but it must be done correctly to achieve accurate test results. Testing helps you quickly identify various issues such as open circuits, short circuits, or incorrect connections. The main steps are:
- Prepare the Equipment - Check the battery and turn on the LAN tester.
- Connect One End of the Cable - Plug one end with an RJ45 connector into the sending port (Main Unit).
- Connect the Other End - Plug the other end into the receiving port (Remote Unit).
- Select Test Mode - Switch to the "TEST" position and observe that the "VERIFY" light turns on.
- Initiate Testing - Press the test button to start scanning each pair of wires (1-8, G).
- Adjust Speed - Press the "OPEN" button to switch between fast and slow test speeds.
- Read Test Results - Observe the sequence of lights indicating the status of each wire pair.
- Analyze Issues - Check for open circuit, short circuit, or crossover alerts.
- Fix and Retest - If issues are found, fix them and retest.

Frequently Asked Questions
How do you test a LAN cable?
To test a LAN cable, follow these steps:
- Connect one end of the cable to the main tester.
- Connect the other end to a remote device or to the test port on the main tester (depending on the model).
- Press the test button on the tester.
- Wait for the tester to complete the testing process (this may take a few seconds to minutes, depending on the type of test).
- Read the results from the LED lights or display screen.
- If there is an error result, check and reinsert the cable ends.
What does a LAN cable inspection entail?
LAN cable testing includes several types of tests:
- Wire Map - Checks the connections and sequence of each wire in RJ45
- Continuity - Tests for continuity of the cable
- Short Circuit - Detects short circuits between wire pairs
- Open Circuit - Detects breaks or unconnected wires
- Split Pair - Checks wire pairs that are not twisted together as per standard
- Length - Measures the length of the cable (available in models with this feature)
- Cross Talk - Measures crosstalk between wire pairs (available in high-end models)
- PoE - Tests power delivery over the LAN cable (available in supported models)
What are the statuses of a LAN cable?
The LEDs on the LAN cable checker indicate various statuses as follows:
- All lights are on in sequence: The line is working normally, and the connection is correct.
- One light does not turn on: That line may be broken or improperly connected.
- Lights are not in the correct sequence: There is a wrong connection (miswire), such as wire 1 connecting to wire 3.
- Abnormal blinking lights: There may be a short circuit between the lines.
- All lights are off: The line may be completely broken or not connected at all.
- No light on the Remote section: This could be due to an excessively long cable, poor quality of the line, or connection issues.
How do I connect a Lan network?
The steps to connect a LAN network are as follows:
- Prepare the equipment - Computer or network device, Ethernet cable, and network equipment (such as switch or router)
- Connect the cable - Plug one end of the Ethernet cable into the Ethernet port on the computer or device
- Connect to the network - Plug the other end into a switch or router
- Check the connection - Observe the LED lights on the Ethernet port to see if they are lit or blinking
- Set IP address - Set up automatic (DHCP) or manual IP address configuration
- Test the connection - Test the connection using the ping command or by opening a web browser
