Abstract

The invention provides an optical fiber manufacturing technique including a line cutting step, a pre-treatment step, a negative pressure glue absorbing step, a pre-heating step, a step of penetrating fibers through a sleeve and a solidification step. The invention has beneficial effects that excessive concave or convex volume of optical fibers relative to an end face of a ceramic insert core is prevented and fiber breakage proportion is also reduced; optical fiber height of an optical fiber patch cord product is controlled in a range from -100nm to +50nm and the optical fiber height reject ratio is controlled within 0.1 %.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to an optical fiber manufacturing process. Background technique [0002] The optical fiber cable is made of the optical fiber, the coating layer, and the outer sheath, which are fused with high temperature and an adhesive. The optical fiber, the coating layer, and the outer sheath are arranged sequentially from the inside out. In the prior art, optical cables are usually used in the field of communication. In the process of use, it is usually necessary to set a tail handle at the head and tail of the optical cable to form an optical fiber jumper to facilitate connection. The tail handle is composed of a socketed metal tail handle and a ceramic ferrule. Usually, the stripped optical fiber is inserted into the space reserved by the ceramic ferrule and the central shaft of the metal tail handle and fixed by pouring glue to achieve the purpose of fixing. The inserted optical fiber ...
