What tool is used to measure the length of a network cable?

The most accurate tool for measuring the length of a network cable directly is a cable length meter. This device provides a straightforward method to measure the physical length of the cable, ensuring that it is within the specified limits for installation and performance standards. In addition, an Optical Time-Domain Reflectometer (OTDR), while primarily designed to test the integrity of fiber optic cables by measuring the time and intensity of light reflections, can also determine the length of the fiber being tested by analyzing the reflected signals.

By utilizing both a cable length meter and an OTDR, you can achieve a comprehensive understanding of not only the length measurement but also the performance characteristics of the cable, especially in fiber optic applications. This dual-approach ensures that any installation adheres to required specifications and maintains network efficiency. Therefore, both tools are valid methods for measuring cable length, particularly in situations where different types of cables are involved.
