In order to solve the problem of low coupling efficiency and low rate of the existing Triplexer optical components, the novel high-speed 2.5Gb / s Triplexer optical component is designed based on low-speed Triplexer optical component. A polarization-dependent optical isolator is applied and the crystal material is improved. Besides, different Receptacle angles are also compared. Then, Combined with ABCD transfer matrix method and coupling con- straints Triplexer light beam transmission performance is analyzed and ZEMAX software is used to design aspheric collimator lens and grin Lens parameters. Furthermore, the x, y and z direction coupling error are analyzed. The results indicate that the Triplexer optical component can be applied to 2.5Gb / s optical transmission system, the thickness of the isolator is reduced by 2. 275mm; the coupling efficiency is as high as 77.76%. In addition, optimal coupling steps are obtained to effectively optimize the coupling process. The optical component has the characteristics of high coupling efficiency, high yield and high integration.
