Problems solved by technology

The general adjustable optical splitter adopts the method of adding stress to the fusion cone part of the ordinary fiber-optic coupler to change the splitting ratio of the two outlets. The disadvantage of this method is that the adjustable range is small, the control accuracy is low, and the application value is relatively low. limited

Abstract

The invention relates to an adjustable light splitter. The adjustable light splitter comprises a first prism and a second prism which have an adjustable distance, the first lateral surface of the first prism is arranged opposite to the first lateral surface of the second prism, an air gap is reserved between the two first lateral surfaces, and incident light is incident from the second lateral surface of the first prism; when the first prism is far away from the second prism, the incident light is totally reflected and output by the first lateral surface of the first prism; when the first prism is tightly attached to the second prism, the incident light is directly output through the first prism and the second prism, and total reflection is not produced; when the first prism is close to the second prism, one part of incident light is reflected and output by the first lateral surface of the first prism, and the other part of incident light is output through the second prism; and the intensity of the reflected output light and the intensity of the transmitted output light are changed together with the distance between the two prisms. The intensity and the light splitting ratio of two paths of light are adjusted only by adjusting the distance between the two prisms; and the adjustable light splitter has the advantages of simple structure, low cost, high control precision, large adjustable range and the like.

Description

technical field [0001] The invention relates to an adjustable optical splitter, which belongs to the technical field of optical fiber communication. Background technique [0002] As the application of optical fiber network becomes more and more popular, especially the popularization and application of fiber-optic cable to the home (FTTH) and fiber-optic cable television (CATV), the demand for optical splitters is increasing. At present, the general optical fiber type or waveguide type optical splitting devices can only provide a fixed splitting ratio. With the development of telecommunication services, telecommunication service providers can control a part of schedulable resources in multiple or even each site, so that the redundant optical power of each branch can be greatly compressed, thereby saving a considerable part of optical amplifiers, reducing the cost of the entire system and Operating costs, thereby improving service reliability and flexibility, and increasing r...
