Method and device for treating end surface of optical fiber coating layer

The invention provides a method and a device for treating the end surface of an optical fiber coating layer. The method sequentially comprises the steps as follows: A, an optical fiber is fixed in a fixture; B, the fixture is placed on a cutting device, and a blade in the cutting device cuts the optical fiber in a rolling manner; and C, the cut optical fiber and the fixture are placed on a heating device together, and the heating device heats a cutting surface of the optical fiber. According to the method for treating the end surface of the optical fiber coating layer, when the optical fiber is cut, the blade in the cutting device performs rolling type cutting, so that the optical fiber bears the force uniformly, the cutting surface of the optical fiber can be guaranteed to be flat; the rolling type cutting manner has small damage to the optical fiber, so that the own form characteristics of the optical fiber can be maintained furthest, and deformation of the optical fiber is reduced; and besides, trace defor
