Embodiment 1

[0029] Embodiment 1: with the Ge that has PES organic plastic coating layer 15 Sb 20 Se 65 Taking chalcogenide glass optical fiber as an example, it is processed into FC type chalcogenide glass optical fiber connector. The processing method includes the following steps:

[0030] 1) Select a section of Ge with a PES organic plastic coating 15 Sb 20 Se 65 For chalcogenide glass optical fiber, prepare two ceramic ferrules with spherical end faces. The inner diameters of the two ceramic ferrules are both 250 μm, and prepare two sets of conventional connection components required for the assembly of optical fiber connectors;

[0031] 2) Soak both ends of the chalcogenide glass optical fiber in a beaker filled with dimethylacetamide. After 8 minutes, the organic plastic coating on the surface of the optical fiber at both ends falls off by itself, exposing a bare fiber with an outer diameter of 240 μm at both ends. Optical fiber, take out the two ends of the optical fiber from d...

Embodiment 2

[0047] Embodiment 2: with the Ge that has PPSU organic plastic coating layer 15 Sb 15 Se 70 Taking chalcogenide glass optical fiber as an example, it is processed into FC type chalcogenide glass optical fiber connector. The processing method includes the following steps:

[0048] 1) Select a section of Ge with a PPSU organic plastic coating 15 Sb 15 Se 70 For chalcogenide glass optical fiber, prepare two ceramic ferrules with spherical end faces. The inner hole diameters of the two ceramic ferrules are both 125 μm, and prepare two sets of conventional connection components required for the assembly of optical fiber connectors;

[0049] 2) Soak both ends of the chalcogenide glass optical fiber in a beaker filled with ether. After 6 minutes, the organic plastic coating layer on the surface of both ends of the optical fiber will fall off by itself, exposing a bare optical fiber with an outer diameter of 120 μm at both ends. Take out the two ends of the fiber respectively fro...

Abstract

The invention discloses a processing method for an FC-type chalcogenide glass optical fiber connector. Before polishing, only the organic plastic coating layers on the surfaces of two ends of an optical fiber are removed, and the optical fiber is sleeved by a plastic casing pipe, so as to guarantee that the optical fiber cannot be broken or damaged in a processing and use process. The method fixes a naked optical fiber through a ceramic plug core, wherein the butt joint end face of the ceramic plug core is a spherical surface. The ceramic plug core can be selected from ceramic plug cores which are commonly used for silica fiber jump wires, and the elements are easy to get and are wide in source. The method cane effectively iron out the defects that a chalcogenide glass optical fiber is poor in mechanical strength, is liable to be broken and is difficult to machine. The method achieves the quick, simple and convenient processing of the FC-type chalcogenide glass optical fiber connector, and the prepared FC-type chalcogenide glass optical fiber connector is high in end face quality, is low in insertion loss, and can be conveniently connected with other optical fiber equipment in a coupled manner. The method can be used for the large-scale processing and preparation of the FC-type chalcogenide glass optical fiber connectors, provides a new idea for the processing of the FC-type chalcogenide glass optical fiber connectors, and fills up a gap in the country.

Description

technical field [0001] The invention relates to a processing method for an optical fiber connector, in particular to a processing method for an FC type chalcogenide glass optical fiber connector. Background technique [0002] Optical fiber connector is a device used for detachable connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and Minimizing the impact on the system due to its intervention in the optical link is a basic requirement for fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems. FC fiber optic connector is a kind of fiber optic connector. This connector was first developed by NTT Corporation of Japan. It uses quartz optical fiber. The external reinforcement method is a metal sleeve, and ...
