Method and system for optical fiber identification through fusion splicer and special core regulation support

Abstract

The present invention provides a method for optical fiber identification through a fusion splicer. The method comprises the following steps of: putting optical fibers on a core regulation support; moving the optical fibers in an optical axis of an objective lens of the fusion splicer through the core regulation support; and collecting signals through the objective lens and the CCD to determine thetype of the optical fibers. Devices on a current welding device can be reused with no need for adding a focusing mechanism. The present invention further provides a system for optical fiber identification through a fusion splicer. The system comprises a core regulation module, a collection module, a comparison module, a selection module and a transmission module. The present invention further provides a special core regulation support for achieving the method for optical fiber identification through a fusion splicer. A housing is internally provided with two regulation holes, an elastic member of a regulation module is provided with a through hole on the housing, a swing bar is extended on the elastic member, a transfer bar penetrates the through hole and the regulation holes, a steel ball is put at the transfer bar and the swing bar, and an optical fiber location block is fixed on the swing bar and is provided with a spacing groove. The core regulation support drives the optical fibers to complete movement so as to meet the design requirement of the method for optical fiber identification.

Description

technical field [0001] The invention relates to a method for identifying optical fibers by an optical fiber fusion splicer. [0002] The invention also relates to a system for identifying optical fibers by an optical fiber fusion splicer. [0003] The invention further relates to a special core-adjusting support for the method for identifying optical fibers of an optical fiber fusion splicer. Background technique [0004] The fiber fusion splicer is used to splice a variety of optical fibers. During the splicing operation, different types of optical fibers generally need to set different splicing parameters. The image-based optical fiber identification method generally changes the optical fiber image through focusing and other optical devices, and analyzes Compare these changes to determine the type of fiber. Relative movement between the optical fiber and the objective lens (that is, the defocusing and zooming process of the observed object), for example, for G.652, G.653...

AI Technical Summary

Problems solved by technology

The existing solution is to achieve the purpose of focusing through the movement of the objective lens. To achieve the movement of the objective lens in the optical fiber fusion splicer, an additional focus adjustment mechanism is required. The focus adjustment mechanism contains two or more motors, and the objective lens is driven by the motor. Move back and forth to achieve zooming, but the operation of the focusing mechanism is complicated, takes up a lot of space, and increases manufacturing costs
