Optical fiber detecting device

The present invention relates to an optical fiber detecting device, and more particularly to an optical fiber detecting device for detecting a multi-core optical fiber.

With the evolution of the information age, users have increasingly demanded data transmission efficiency, and the transmission efficiency of traditional cables has been unable to meet the needs of the general public.

Therefore, optical fibers with a large number of advantages have gradually replaced traditional cables and become the current data transmission network. The most important transmission medium.

In order to ensure the quality of fiber transmission, in general, before the fiber is laid, the fiber must be tested to determine whether the fiber is broken or damaged. However, depending on the structure of the optical fiber, the optical fiber can be classified into many types, for example, a single-core optical fiber, a hollow fiber (Hollow Fiber), or a multi-core fiber (Multi Core Fiber), among which different types of optical fibers have different failure scenarios.
