Title:
BIDIRECTIONAL OPTICAL TRANSMISSION AND RECEPTION MODULE
Document Type and Number:
WIPO Patent Application WO/2017/111375
Kind Code:
A1
Abstract:
A bidirectional optical transmission and reception module according to the present invention comprises: an optical transmission unit for outputting a transmission signal; an optical reception unit for receiving a reception signal; an optical fiber refracting, on an interface, a portion of the transmission signal outputted from the optical transmission unit so as to make the same be incident within a light-receiving angle, and completely reflecting all or a portion of the reception signal on the interface so as to make the same be incident to the optical reception unit; and a glass capillary for supporting the optical fiber and passing, therethrough, the reception signal completely reflected on the interface, wherein the optical fiber has an angle of the interface such that an optical path of the transmission signal incident within the light-receiving angle of the optical fiber and an optical path of the reception signal incident to the optical reception unit differ from each other. According to the present invention, the optical path of the transmission signal, which is outputted from the optical transmission unit and is incident to the optical fiber, and the optical path of the reception signal, which is transmitted through the optical fiber and is incident to the optical reception unit, are formed to be different from each other on the interface of the optical fiber, and thus theoretical restrictions on a wavelength interval of the transmission and reception signals are removed when the transmission and reception signals are separated within an entire wavelength band to be used.
