Abstract:
1. A bidirectional optical transceiver comprising: a wavelength-selecting filter placed or an optical axis for passing a first optical signal therethrough and reflecting a second optical signal perpendicularly to a traveling path of the second optical signal; an optical fiber having a face opposite to the wavelength-selecting filter and an end surface inclined at an angle of φ with respect to a normal line perpendicular to the optical axis; a transmitting module placed on the optical axis in opposition to the optical fiber with respect to the wavelength-selecting filter and having a light source for generating the first optical signal and outputting the generated first optical signal to the wavelength-selecting filter at a predefined inclined angle with respect to the optical axis; and a receiving module for detecting the second optical signal reflected from the wavelength-selecting filter.
