Design And Research Of Triplexer-the Most Important Component In FTTH

FTTH is the best solution for future fiber access networks. It is an inevitable trend in the development of optical communication systems. As a core optoelectronic components used in FTTH, Triplexer has a significant and forward-looking value in research. The main task is the research of Triplexer. Begin with its initial application form: separated Triplexer, it analyses the optical theory of Triplexer in detail. Then the overall design and its components design is completed, followed that, the research of Triplexer is done. Finally, is the research of senior form: integrated Triplexer. Contrast with the separated components, it uses the unique method for integrated research. The explorated design is made, and the preliminary results of simulation has got. Contents of this thesis are listed below:Firstly, beginning with the application of FTTH, it introduces the study, development, the overall trend of Triplexer.Secondly, there is a brief introduction of integrated optoelectronic components and their significance of research. Then, the theory, method, software used in design of integrated optoelectronic components is given.Then, the body of the article, separated Triplexer is designed. A very detailed optical analysis and design is made. Parameters such as working distance, the lens aperture, relative numerical aperture are discussed. Following that, the overall and separated design is completed. The basic experiment is made, too.Finally, the exploration of the integrated Triplexer is done. The overall design which lays a solid foundation for further study is made, too.Along with the growing promotion of FTTH, Triplexer will play an increasingly important role in it. Because the research is just start, the winner will be the one who has made excellent results first. The results have a great role in promoting the development of FTTH, too. Therefore, Triplexer study has greater research value and practical significance.
