FAQ
Q： Do I need a cable tester?
A： Certainly!
Whether you’re installing new cables or troubleshooting existing ones, a cable tester is indispensable in the process. For cables, crucial tests include assessing length, wire map, attenuation, NEXT (Near-End Crosstalk), DC loop resistance, and return loss. These tests ensure the reliability and optimal performance of datacom cabling, making a cable tester a valuable tool for professionals in the field.
Q： What is the standard for cable testing?
A： According to the IEEE 400.2 VLF standard, it is suggested to perform cable testing at 2.5 – 3 times its usual line-to-ground voltage (2.5 Vo – 3Vo) for a minimum duration of 30 minutes. Extended testing periods are recommended, especially at frequencies lower than 0.1Hz.
Q： How many types of cable tests are there?
A： Common cable tests include:
1. Continuity Test
2. Insulation Resistance Test
3. Wiremap Test
4. Length Measurement
5. Attenuation Test
6. NEXT Test
7. Return Loss Test
8. Propagation Delay Test
9. Cable Fault Location
10. Dielectric Withstand Test
11. Impulse Voltage Test
Q： What are the risks of damaged cable?
A： Damaged cables pose risks such as electrical hazards, fire, equipment failures, signal interference, safety concerns, financial losses, environmental impact, compromised security, increased maintenance costs, system instability, and regulatory compliance issues. Regular inspections and prompt repairs are crucial for risk mitigation.
