Fiber cutting before fiber splicing is an important step, which has a great impact on splice strength and splice loss. This article will introduce common fiber cleavers and explain the basic principles of their use.

1. Why do we need to use fiber cleaver under normal circumstances?

We can directly look at the picture. It is obvious that the end face of the optical fiber cut with a fiber optic cutter is smoother and smoother, and the transmission will be more stable in subsequent use.

2. Principle of optical fiber cutting

The principle is similar to cutting glass with a glass cutting knife. The following is an introduction to each step.

Fix the optical fiber: Use the four stainless steel rubber pads on the upper, lower, left and right to hold the optical fiber.

Cut a knife mark on the optical fiber: Use the sliding blade to cut a knife mark on the optical fiber.

 Cutting: Use the drop hammer to break the optical fiber from the opposite direction of the knife mark.
