Abstract:
(EN) An optical transmission/reception module which can ensure the transmission quality without providing a collimating optical device and a narrow-band filter. A fiber (7) with a grating which has a function of the narrow-band filter to block transmission of an optical signal in a band other than a narrow band containing a wavelength of 1310 nm, a narrow band containing a wavelength of 1490 nm, and a narrow band containing a wavelength of 1550 nm is used as an optical fiber for transmitting an optical signal with the wavelength of 1310 nm that has passed through WDM filters (4, 5) to a station and transmitting optical signals with the wavelengths of 1490 nm and 1550 nm transmitted from the station to the WDM filter (5).
(FR) L'invention porte sur un module d'émission/réception optique qui peut garantir la qualité de transmission sans qu'un dispositif optique de collimation et qu'un filtre à bande étroite ne soient prévus. Une fibre (7) avec un réseau qui a une fonction de filtre à bande étroite pour bloquer la transmission d'un signal optique dans une bande autre qu'une bande étroite contenant une longueur d'onde de 1 310 nm, une bande étroite contenant une longueur d'onde de 1 490 nm et une bande étroite contenant une longueur d'onde de 1 550 nm, est utilisée en tant que fibre optique pour transmettre un signal optique ayant une longueur d'onde de 1 310 nm, qui est passé à travers des filtres de multiplexage par répartition en longueur d'onde (WDM) (4, 5), jusqu'à une station et pour transmettre des signaux optiques ayant des longueurs d'onde de 1 490 nm et 1 550 nm transmis de la station au filtre WDM (5).
(JA)  本発明は、コリメーティング光学機器や狭帯域フィルタを設置することなく、伝送品質を確保することができる光送受信モジュールに関する。WDMフィルタ(4,5)を透過してきた波長1310nmの光信号を局側に伝送するとともに、局側から送信された波長1490nm,1550nmの光信号をWDMフィルタ(5)側に伝送する光ファイバとして、波長1310nmを含む狭帯域、波長1490nmを含む狭帯域及び波長1550nmを含む狭帯域以外の帯域の光信号の透過を阻止する狭帯域フィルタの機能を有するグレーティング付ファイバ(7)を用いる。
