A small size compact sparse wavelength division multiplexing optical add-drop multiplexer module

Abstract

The utility model relates to a kind of space cascade wave division optical add-drop multiplexing technology, specifically a small size compact sparse wave division multiplexing optical add-drop multiplexer module, including multiple single-fiber collimating composite structures and two single-fiber collimating prism assemblies, one single-fiber collimating prism assembly is used as the input end of module, and the other single-fiber collimating prism assembly is used as the output end of module;Multiple single-fiber collimating composite structures are arranged between two single-fiber collimating prism assemblies, and are cascaded in turn. Space cascade is used, compared with three-port device cascade OADM optical add-drop multiplexing module, smaller volume, smaller loss;It can be packaged using CCWDM aluminum box, greatly reducing the volume of use, that is, simple OADM design requirements can be completed, with exquisite structure, great economic value and use value, simple process structure, small volume, convenient production.
