Protector for optical fiber fusion

Abstract

The invention discloses a protector for optical fiber fusion, comprising protection boxes and connection racks for the optical fiber fusion; the protection boxes for the optical fiber fusion comprise box bodies of the protection boxes and screw caps, wherein the box bodies of the protection boxes for the optical fiber fusion are axially provided with installation grooves for placing optical fibers, slide grooves are provided at outer sides of the box bodies, the screw caps are arranged on two ends of the box bodies of the protection boxes of the optical fiber fusion and in a threaded connection with the box bodies of the protection boxes of the optical fiber fusion, and the screw caps are provided with holes for optical fibers extending in and out; the connection racks comprise slide channels which are in slide fit with the slide grooves. Provided is a device used for protecting the safety of fusion points between optical fibers after fusion welding. The protector for the optical fiber fusion is small in size and can protect the safety of the fusion points after the fusion welding. The protector enables the fusion connection of various optical fibers to be carried out smoothly and protects the fusion points of optical fibers after the fusion connection. The protector is excellent in terms of optical properties and mechanical properties, and convenient for fiber connection, high in success rate, and better than fiber mechanical connection in various performance indexes.

Description

technical field [0001] The invention relates to the technical field of optical fibers, and more specifically, to an optical fiber fusion splicing protector. Background technique [0002] To a certain extent, the cold connection of the optical fiber affects the reliability and performance of the optical transmission system. At present, the connection between FTTH (Fiber To The Home, fiber to the home) engineering fibers often adopts cold splicing technology, that is, two optical fibers are mechanically operated to transmit light through optical fiber matching paste, so that the light can be transmitted continuously. [0003] However, the mechanical splicing between optical fibers is only the close contact between the end faces of the optical fibers, and its conduction effect on light depends on the degree of tightness of the end faces of the optical fibers. Due to the high technical index requirements, the construction is difficult, and it is not easy for construction person...
