WAVELENGTH DIVISION MULTIPLEXING OPTICAL MODULE

摘要

PURPOSE: A wavelength division multiplexing light module is provided to prevent the degradation of light combining efficiency, thereby realizing the miniaturization. CONSTITUTION: An optical signals of many wavelength is transmitted to an optical coupling block(110) through an optical fiber. Combination with an optical filter(200) for wavelength division of the optical block and light fiber is performed through a receptacle(114) of the light combining block. The light signal of an optical fiber core of optical cable passes through an input collimate lens surface(111') of the light combining block. The light signal is converted into a parallel light. Therefore, the light signal is transmitted without light loss in relatively far distance.
