Optical fiber coupling bench

Abstract

The invention relates to an optical fiber coupling table used for optical communication and optical network technology, which comprises an upper holding table and a lower holding table. The lower holder table comprises a shell fixedly connected with a base, wherein the inside of the shell is provided with a lower sleeve having a bedplate, and X-axis and Y-axis adjusting mechanisms arranged on theshell are connected with the lower sleeve respectively. A clamping sleeve is in sleeve joint with the inside of the lower sleeve, and a spherical universal device is movable sleeve join with the inside of the clamping sleeve through a spring connected with the bedplate. The upper part of the spherical universal device is fixedly connected with a screw rod. The central parts of the spherical universal device and screw rod are provided with through holes and a lower coupling piece is clamped in the through holes. An inner socket in insert joint with a pin of the lower coupling piece is connected with a circuit board arranged on the base through a connecting wire. An upper coupling piece is clamped in the upper clamping table and a Z-axis adjusting mechanism is arranged inside the upper clamping table. The coupling table has the characteristics that the upper and lower coupling pieces have good clamping effect, stable connection, convenient operation, quickness, good coupling quality andhigh efficiency, is particularly suitable for industrial and large-scale production and contributes to the reduction of production cost.

Description

technical field [0001] The invention relates to a laser assembly, a receiver assembly used in optical communication and optical network technology, and an optical fiber coupling platform packaged with a single-fiber bidirectional assembly. Background technique [0002] Existing optical transmitting and receiving devices are made by packaging semiconductor lasers or semiconductor optical receivers into products with optical communication standard interfaces, and the most critical process is optical fiber coupling. The existing optical fiber coupling table generally has a ball (or roller) structure. The upper clamping table of the optical fiber coupling table is fixed and coated on the ceramic ring, optical fiber and ceramic ferrule in the upper shell, and the lower clamping table is fixed and covered on the The light beam and laser diode in the lower shell, and the lower part of the diode are fixedly connected to the pins. On the fiber coupling table, three-dimensional adjust...

AI Technical Summary

Problems solved by technology

However, due to structural reasons, the external power line of the optical device needs to be configured separately. It is very inconvenient to manually insert the pins in the lower clamping table from the base of the lower part of the coupling table, and because the upper and lower parts cannot automatically fit the workpiece during coupling. High requirements on the parallelism of the workpiece surface

During welding and external force, the predetermined value of the optical device is easy to change, and the production efficiency is low
