Light spot machine debugging system and light spot machine debugging method for medium/long-working-distance single-mode single-fiber collimators

Abstract

The invention relates to a light spot machine debugging system and a light spot machine debugging method for medium / long-working-distance single-mode single-fiber collimators. The system comprises a laser point light source, a light spot machine, a medium / long-working-distance single-mode single-fiber collimator, a five-dimensional adjusting frame, and a sliding table. The laser point light source is connected with the medium / long-working-distance single-mode single-fiber collimator. The light spot machine is connected with a computer. The medium / long-working-distance single-mode single-fiber collimator is arranged on the five-dimensional adjusting frame. The light spot machine is arranged on the sliding table. By using the light spot machine debugging system and the light spot machine debugging method for medium / long-working-distance single-mode single-fiber collimators, the light path debugging difficulty is reduced, the debugging precision is improved, the medium / long-working-distance single-mode single-fiber collimator has smaller insertion loss and higher degree of pairing, and the consistency and first-pass yield of products are higher, the debugging time is reduced, and the work efficiency of employees is improved. The system and the method are also applicable to medium / long-working-distance single-mode single-fiber collimators of which the medium / long working distance is at specific bands, such as 850nm and 1060nm.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to the technical field of optical path debugging, and specifically refers to a spot machine debugging system and method for a single-mode single-fiber collimator with a medium and long working distance. Background technique [0002] At present, the common debugging system of the single-mode single-fiber collimator with medium and long working distance is the reflection method, transmission method or automatic debugging through the fine-tuning frame; the reflection method debugging is to use the mirror with the corresponding wavelength bandwidth at half of the working distance The reflection method debugs the single-mode single-fiber collimator with medium and long working distance to minimize the reflection insertion loss. The optical path includes a laser point light source of corresponding wavelength, a splitting fiber coupler, a reflector of corresponding wave...

Problems solved by technology

Fully automatic debugging generally at least through the automatic adjustment frame and optical power detector or beam quality analyzer or a combination of the two, the equipment in this debugging system is relatively large, and it is expensive and prone to failure, and the settings in the equipment are relatively complicated , the debugging system is too dependent on the judgment made by the equipment, thus reducing the subjective initiative of people
