Ceramic optical fibre cold coupler

Abstract

The invention discloses a ceramic optical fibre cold coupler comprising a ceramic hollow tube, a fixed base and a stainless steel sleeve. The fixed base is connected by using a Hough structure; the ceramic hollow tube is arranged in the fixed base; the stainless steel sleeve is sleeved on the outer side of the fixed base; and the shape of the inner side of the stainless steel sleeve is matched with that of the fixed base. As the optical fibre is fixed by using the ceramic hollow tube and the cavity in the ceramic hollow tube is sealed, the adoption of the ceramic optical fibre cold coupler cannot cause deformation inside the ceramic hollow tube under the external environment, and pollution and loss of matching oil in the cavity, and the ceramic optical fibre cold coupler is convenient for field operators to operate, can improve the assembling efficiency and the coupling reliability of the optical fibres, is suitable for various severe environments and beneficial to the reduction of later faults, and has remarkable practical value.

Description

technical field [0001] The invention relates to an optical fiber connection technology for an optical fiber termination point, and more specifically relates to a ceramic optical fiber cold splicer. Background technique [0002] End-to-end splicing is the process of making an active connection at the end of the fiber. The active connection of optical fibers is generally completed through optical fiber active connectors, but the production process of traditional active connectors is very complicated, and requires skilled technicians to operate, and the production cycle is also long, so it is used at the end of the optical fiber at the construction site of the integrated wiring This fiber optic connector is not possible. For this reason, most of the optical fiber cold splicing technology is used now. The existing cold splice structure of optical fiber is as follows: figure 1 As shown, it mainly adopts a clip-type structure. Before splicing, use a cleaver to smooth the end fac...

Problems solved by technology

[0003] Aiming at the disadvantages in the prior art that the optical fiber cold connection adopts an unsealed clip-type structure, the matching oil is easily polluted or lost, and the V-shaped groove of the plastic bottom plate is easily deformed by the environment, thus causing inconvenient optical fiber docking. The present invention The purpose is to provide a ceramic optical fiber cold splicer that can conveniently and reliably connect optical fibers
