Optical fiber bundle fusion packaging device and packaging method

Abstract

The invention relates to an optical fiber bundle fusion packaging device and packaging method, and belongs to the technical field of optical fiber packaging. The device comprises a lateral pressurizing mold, and the lateral pressurizing mold is arranged in an inner cavity of high-frequency induction heating equipment, so that an induction coil of the high-frequency induction heating equipment surrounds the lateral pressurizing mold. An optical fiber bundle is movably arranged in the lateral pressurizing mold in a penetrating mode and can vertically move along the lateral pressurizing mold. The high-frequency induction heating equipment heats the lateral pressurizing mold, so that the bare fiber section of the optical fiber bundle in the lateral pressurizing mold is softened, then circumferential pressure is applied to the softened bare fiber section of the optical fiber bundle through the lateral pressurizing mold, and fusion packaging of the optical fiber bundle is realized. According to the invention, the operation is convenient, the optical fiber bundle packaging time is shortened, the optical fiber bundle packaging efficiency is improved, and the production cost is reduced. After hot melting, the optical fiber bundle is a homogeneous whole, there is no heterostructure in the optical fiber bundle, and the risk of optical fiber damage caused by thermal stress is avoided.

Description

technical field [0001] The invention relates to an optical fiber bundle fusion packaging device and a packaging method thereof, belonging to the technical field of optical fiber packaging. Background technique [0002] With the continuous development of information technology, the application of optical fiber has become more and more extensive. Optical devices made of optical fibers play an important role in the fields of optical fiber sensing, optical signal processing, medical devices and lighting systems. Among them, optical devices made on the basis of optical fiber bundles can play the role of transmitting multiple different optical signals simultaneously or in time division in various application fields. [0003] At present, the encapsulation method of silica fiber bundles is bonded by adhesives, and the viscosity and particle size of the adhesives affect the tightness of the arrangement of the fiber bundles. During the curing process, the difference in the coefficie...

Problems solved by technology

This method uses the metal coating as the medium to heat-cure the optical fiber bundle into a whole, which overcomes the shortcomings of the adhesive package, but the metallization process of the optical fiber is complicated, and the uniformity of the coating thickness will affect the effect of induction heating, and the metallization cost of the optical fiber is also relatively high. high
