Optical fiber fusion splicing method

Abstract

The invention relates to an optical fiber fusion splicing method comprising the following steps that a. coating layers are removed: the coating layers of the optical fibers in two optical cables in a fusion splicing area are removed by adopting a hot stripping method, then cleaning processing is performed on the surfaces of the optical fibers, and there are at least two optical fibers in the optical cables; b. glue is coated: the optical fibers, of which the coating layers are stripped, in the optical cables are adhered together by glue so that optical fiber bundles are obtained; c. cutting is performed: after glue on the optical fiber bundles obtained through the step b is solidified, the end surfaces of the optical fiber bundles are cut to be flat by a cutting knife; and d. fusion splicing is performed: the end surfaces of the optical fiber bundles of the two optical cables are aligned and then arranged in a fusion splicing machine to perform fusion splicing. The optical fiber fusion splicing method has advantages of being high in efficiency and low in cost.

Description

technical field [0001] The invention relates to the field of optical fiber processing, in particular to an optical fiber fusion splicing method. Background technique [0002] In the construction of optical cables in communication engineering, thermal fusion splicing technology is required when the optical cables are terminated. Existing optical cables generally have multiple optical fibers in them. When performing fusion splicing, it is necessary to remove the coating layer of the fusion splicing part. Since the optical fiber in the optical cable is easily loose without the coating layer, it is difficult to align during fusion splicing, which affects the quality of the optical fiber obtained by fusion splicing. Moreover, for a single optical fiber, a single optical fiber fusion splicer needs to be used for fusion splicing. When there are many optical fibers in the optical cable, it takes a long time for optical fiber fusion and consumes a lot of consumables, which increases ...

Problems solved by technology

When performing fusion splicing, it is necessary to remove the coating layer of the fusion splicing part. Since the optical fiber in the optical cable is easily loosened without the coating layer, it is difficult to align during fusion splicing, which affects the quality of the optical fiber obtained by fusion splicing.

Moreover, for a single optical fiber, it is necessary to use a single optical fiber fusion splicer for fusion splicing. When there are many optical fibers in the optical cable, it will take a long time for optical fiber fusion and consume more consumables, which will increase the production cost.
