Method and device for removing jacket layer of optical fiber

Abstract

The invention discloses a method and a device for removing a jacket layer of an optical fiber. The method comprises the following steps of: cutting up or planing off part of the jacket layer of the optical fiber along the axial direction of the optical fiber by using a tool and ensuring that the thickness of the removed jacket layer is less than or equal to the thickness of the jacket layer; applying a force to the residual jacket layer to strip the jacket layer from the optical fiber. According to the invention, the structure operation is simple, the method and the device are flexible to operate, the size is accurate, the device is convenient to carry and the labor productivity of the process of removing the jacket layer of the optical fiber can be greatly improved.

Description

technical field [0001] The invention relates to a method and a device for removing an optical fiber sheath layer, in particular to a method and a device for removing a silica fiber polymer sheath layer. Background technique [0002] The role of the optical fiber sheath is to protect the inner core-skin structure of the quartz optical fiber, which can effectively reduce or eliminate external damage to the core-skin layer, improve the mechanical strength of the optical fiber product, and improve product performance. [0003] Generally, the thickness of the sheath layer of silica optical fiber is less than 0.20 mm. According to the strength of the adhesion force, the sheath layer is generally divided into tight and loose. In actual use, the precise coupling of many devices requires the removal of the sheath layer, and the existing work of removing the sheath layer, especially the work operation when removing the optical fiber tight sheath layer, is difficult and the yield is lo...

Problems solved by technology

The limitation of this device is that it can only be used in a short distance with a length of less than 2cm, and the length of removing the sheath layer cannot be precisely controlled. Once the operating length is required to be greater than 2cm, due to the excessive adhesion of the sheath layer, It can no longer achieve the effect of smooth removal.

At the same time, the operator exerts a lot of force on the optical fiber during the operation, which is very easy to damage the core and skin layer inside the optical fiber, and the pass rate is low.
