Title (EN) BIDIRECTIONAL OPTICAL TRANSMISSION AND RECEPTION MODULE
(FR) MODULE DE TRANSMISSION ET DE RÉCEPTION OPTIQUE BIDIRECTIONNEL

Abstract:
(EN) 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.
(FR) Un module de transmission et de réception optique bidirectionnel selon la présente invention comprend : une unité de transmission optique pour émettre un signal de transmission; une unité de réception optique pour recevoir un signal de réception; une fibre optique qui réfracte, sur une interface, une partie du signal de transmission émis par l'unité de transmission optique de façon à le rendre incident dans un angle de réception de lumière, et réfléchissant complètement la totalité ou une partie du signal de réception sur l'interface, de manière à le rendre incident sur l'unité de réception optique; et un capillaire en verre pour soutenir la fibre optique et faire passer à travers celle-ci le signal de réception entièrement réfléchi sur l'interface, la fibre optique présentant un angle de l'interface tel qu'un trajet optique du signal de transmission incident dans l'angle de réception de lumière de la fibre optique et un trajet optique du signal de réception incident sur l'unité de réception optique sont différents l'un de l'autre. Selon la présente invention, le trajet optique du signal de transmission, qui est émis depuis l'unité de transmission optique et qui est incident sur la fibre optique, et le trajet optique du signal de réception, qui est transmis par la fibre optique et qui est incident sur l'unité de réception optique, sont formés de manière à être différents l'un de l'autre sur l'interface de la fibre optique, et les restrictions théoriques sur un intervalle de longueur d'onde des signaux de transmission et de réception sont supprimées quand les signaux de transmission et de réception sont séparés dans une bande de longueurs d'onde totale à utiliser.
(KO) 본 발명에 따른 양방향 광 송수신 모듈은, 송신신호를 출력하는 광 송신부; 수신신호를 입력받는 광 수신부; 상기 광 송신부로부터 출력된 송신신호의 일부를 경계면에서 굴절시켜 수광각 이내로 입사시키고, 상기 수신신호의 전부 또는 일부는 상기 경계면에서 전반사시켜 상기 광 수신부로 입사시키는 광섬유; 및 상기 광섬유를 지지하며, 상기 경계면에서 전반사되는 수신신호를 통과시키는 글래스 캐필러리;를 포함하며, 상기 광섬유는, 상기 광섬유의 수광각 이내로 입사시키는 상기 송신신호의 광경로와 상기 광 수신부로 입사시키는 상기 수신신호의 광경로가 서로 상이하도록 상기 경계면의 각도를 갖는 것을 특징으로 한다. 본 발명에 의하면, 광 송신부에서 출력되어 광섬유로 입사되는 송신신호의 광경로와, 광섬유를 통해 전송되어 광 수신부로 입사되는 수신신호의 광경로가 광섬유의 경계면에서 서로 상이하도록 구성됨으로써, 사용되는 전체 파장대역 내에서 송수신신호를 분리함에 있어서 송수신신호의 파장간격에 대한 이론적 제약이 없어지게 된다.
