    摘要: An optical assembly includes an input fiber (30) and an output fiber (31), a ferrule (32) receiving the input and output fibers therein, a molded lens (33) and a filter (34). The molded lens includes a solid cylindrical main body (334), and an annular protrusion (333) extending from a front end of the main body. The main body has an oblique rearward end face (331), and an aspherical forward end face (332) opposite to the rearward end face. The ferrule also has an oblique forward end face (322) which is close to and substantially parallel to the oblique rearward end face of the molded lens. The filter is attached to a forward end of the annular protrusion. Light rays from the input fiber pass through and are made parallel by the molded lens. Parallel rays of a predetermined wavelength are transmitted through the filter. Parallel rays having other wavelengths are reflected at the filter and transmit through the output fiber.
