What is the purpose of a "cleaver" in fiber optics?

The cleaver is an essential tool in fiber optics, specifically used to ensure a clean and precise cut at the end of a fiber optic strand. The purpose of a cleaver is to create a flat, clean cut on the fiber end, which is crucial for optimal splicing. This clean cut allows for better alignment and contact between the fibers being joined, which in turn helps to minimize signal loss and reflection at the splice point. A properly cleaved fiber ensures that the light transmission characteristics are maintained, directly impacting the performance of the optical network. It is important to have an accurate and clean cut, as any irregularities can lead to poor connectivity and reduced signal quality.

In contrast, other tools and processes serve different purposes in the fiber optic installation process. For example, stripping tools are used to remove the outer jacket of the fiber, testing equipment is applied to verify the integrity of connections, and calipers measure diameter, but none of these fulfill the specific function of preparing the end of a fiber for splicing as effectively as a cleaver does.
