A Fiberscope is an optical instrument used to examine the inner workings of cables. It consists of an objective lens, a coherent fiber bundle, and an eyepiece. The fiber bundle is usually flexible and is composed of thousands of tiny optical fibers. The objective lens captures the image, which is then transferred to the eyepiece where it can be viewed.

The use of a Fiberscope is essential for cable maintenance and troubleshooting, as it can reveal any structural damage or internal blockages. Fiberscopes are also used to inspect cables that are not accessible by other methods. This can be due to their location, size, or any other factor that prevents the use of traditional testing methods.

Fiberscopes can be used to inspect cables of various sizes and lengths, including those of commercial and industrial facilities. The small size of the instrument makes it ideal for working in tight spaces, as it can be maneuvered easily. The device can also be used to inspect underground cables, as the flexible fiber bundle allows for the image to be transmitted even in tight and awkward spaces.

Fiberscopes are also used to diagnose internal cable defects, such as corrosion, loose connections, and broken wires. By providing a detailed image of the internal cable structure, the device can be used to identify the cause of any faults or malfunctions. Fiberscopes can also be used to identify the exact location of any defects, which is essential for properly diagnosing and resolving the issue.

Overall, Fiberscopes are an invaluable tool for cable maintenance and troubleshooting. The device is used to inspect cables of any size and length, and can provide detailed images of the internal cable structure. This allows for any faults or malfunctions to be quickly identified and repaired.
