Abstract: front page image
(EN)The present invention relates to a light merging/branching device by which branching of downlink signals and merging of uplink signals can be performed by the same optical device, and the merging loss of the uplink signals can be reduced. This light merging/branching device is provided with: a light merging/branching means which merges and outputs a plurality of uplink signals in multi mode, and branches and outputs downlink signals in single mode; and a bidirectional light propagation means which propagates and outputs the uplink signals output from the light merging/branching means in multi mode, and propagates and outputs the downlink signals to the light merging/branching means in single mode.
(FR)La présente invention concerne un dispositif de concentration/dérivation de lumière permettant de réaliser la dérivation de signaux en liaison descendante et la concentration de signaux en liaison montante à l'aide du même dispositif optique, et permettant de réduire la perte de concentration des signaux en liaison montante. Ce dispositif de concentration/dérivation de lumière comprend : un moyen de concentration/dérivation de lumière, qui concentre et sort une pluralité de signaux en liaison montante en multimode, et qui dérive et sort des signaux en liaison descendante en monomode ; et un moyen de propagation de lumière bidirectionnel qui propage et sort les signaux en liaison montante provenant du moyen de concentration/dérivation de lumière en multimode, et qui propage et sort les signaux en liaison descendante vers le moyen de concentration/dérivation de lumière en monomode.
(JA) 本発明は、下り信号の分岐と上り信号の合流とを同一の光デバイスで実現し、上り信号の合流損失を低減させる光合流分岐器に関する。本発明の光合流分岐器は、複数の上り信号をマルチモードで合流して出力し、下り信号をシングルモードで分岐して出力する光合流分岐手段と、前記光合流分岐手段から出力された前記上り信号をマルチモードで伝播させて出力し、前記下り信号をシングルモードで伝播させて前記光合流分岐手段に出力する双方向光伝播手段とを備えることを特徴とする。
