Optical module for bidirectional communication improved incident angle precision of ferruled optical fiber

摘要

The present invention relates to a bi-directional optical module for optical signal transmission in the wavelength division method , the optical signal transmission , the light emitting element and a light receiving element for receiving ; The light-emitting element and a light receiving element are obliquely disposed such that with respect to the corresponding sides of the light wavelength for transmission and reception wavelength separation filter for selectively separating the light wavelength ; And is arranged on an optical axis passing through the light emitting element or any one of the light-receiving element and the wavelength separation filter , and opposite to the wavelength separation filter , including the end of the APC type of processing and the inclined angle of incidence due to the filter surface , such as the APC structure the ferrule of the ferrule the optical fiber is arranged obliquely with respect to the optical axis to correct the error ; bi-directional optical module , comprising the disclosed
