Question: 1 / 400

What method is used to determine the approximate length of a fiber cable?

Sequential marker

The sequential marker method is commonly used to determine the approximate length of a fiber cable. This method involves using markers or tags placed at regular intervals along the length of the fiber optic cable during installation or manufacturing. By reading these markers, technicians can easily visualize and measure the length of the cable without the need for extensive physical measurements. This method is particularly advantageous in environments where physical measurement may be challenging, allowing for a quick and efficient assessment of cable length.

Using markers also aids in documentation and helps ensure that installation meets specific requirements or standards. The simplicity of this method makes it an effective choice for professionals working with fiber optics. Other methods, while potentially useful, may not provide the convenient and immediate results that sequential markers do.
