What is the main purpose of using fiber cleavers in fiber optics?

The primary purpose of using fiber cleavers in fiber optics is to prepare fiber ends for splicing. Cleaving involves cutting the optical fiber in such a way that the ends are flat and clean, ensuring a precise fit when two fibers are joined together. A well-cleaved fiber end results in minimal loss of light and maximum performance in the splice. This process is critical, as any imperfections at the end of the fiber can lead to increased signal loss and degradation of the optical signal.

Although enhancing signal transmission, testing light intensity, or connecting different fiber types are important aspects of fiber optics, they are not the direct functions of a fiber cleaver. The cleaver is specifically designed to ensure that the fiber ends are prepared properly so that when they are spliced, they maintain the integrity of the light signal being transmitted.
