METHOD OF MANUFACTURING AN INPUT / OUTPUT DEVICE FOR MULTI-CORE OPTICAL FIBER Russian patent published in 2019 - IPC G02B6/40 

FIELD: fiber-optic equipment.

SUBSTANCE: method of manufacturing an input / output device for multi-core fiber involves using a housing, which is a capillary made from quartz glass with a funnel, using pieces of single-core optical fibers, diameter D of each of which during at least part of fiber section L corresponds to distance Λ between centers of adjacent cores of multi-core fiber, input of glue into funnel of housing of input-output device, arrangement in body of input / output device of sections of single-core fibers, binding said ends of fibers using a thread to obtain a given structure of the cross-section of the input-output device, polishing the end of the input / output device. Prior to placement in housing of input / output device, binding is carried out with a thread of nineteen folded in parallel sections of single-core fibers. Arrangement of the above-mentioned connected nineteen pieces of single-core fibers in the housing of the input / output device is carried out so that their ends having diameter D project from the housing of the input-output device. Then, nineteen sections of single-core fibers having diameter D are inserted into the loop from the filament and projecting from the capillary body, after which the loop is tightened and held in tension until the adhesive solidifies.

EFFECT: possibility of realizing the technological process of creating an input / output device for multi-core optical fiber with nineteen cores without using such preparatory operations as preparation of special guides and precision selection of parameters of used adhesives.
