Abstract:
(EN) An optical transmission cable connector comprises a first optical module and a second optical module. The first optical module includes a cable having a plurality of optical fibers, a plurality of laser diodes for outputting an optical signal corresponding to input data, a channel selector for receiving input data on a smaller number of channels than the number of the laser diodes and distributing it to the same number of laser diodes as the number of channels of input data, and a monitor for monitoring optical output from each of the laser diodes and causing the channel selector to distribute the input data to normal laser diodes. The second optical module includes a greater number of photo-sensors than the number of reception channels of the optical signal, a channel selector for assigning an output signal from the same number of photo-sensors as the number of the reception channels, among the plenty of photo-sensors, to a signal output terminal, and a monitor for monitoring the output signals from the photo-sensors and causing the channel selector to assign the output signals from the photo-sensors which have normally received the optical signal among the photo-sensors, to the signal output terminal.
(FR) L’invention concerne un connecteur de câble de transmission optique comprenant un premier module optique et un second module optique. Le premier module optique comporte un câble ayant une pluralité de fibres optiques, une pluralité de diodes laser permettant de générer un signal optique correspondant à des données d’entrée, un sélecteur de canal permettant de recevoir des données d’entrée sur un nombre de canaux inférieur au nombre des diodes laser et de les distribuer vers le même nombre de diodes laser que le nombre de canaux de données d’entrée, et un moniteur permettant de surveiller la sortie optique provenant de chacune des diodes laser et de conduire le sélecteur de canal à distribuer les données d’entrée vers les diodes laser normales. Le second module optique comporte un plus grand nombre de photocapteurs que le nombre de canaux de réception du signal optique, un sélecteur de canal permettant d’assigner un signal de sortie provenant du même nombre de photocapteurs que le nombre de canaux de réception, parmi la multitude de photocapteurs, à une borne de sortie de signal, et un moniteur permettant de surveiller les signaux de sortie provenant des photocapteurs et de conduire le sélecteur de canal à attribuer les signaux de sortie provenant des photocapteurs ayant normalement reçu le signal optique parmi les photocapteurs, à la borne de sortie de signal.
(JA)  本発明の光伝送ケーブルコネクタは、複数本の光ファイバを有するケーブルと、入力データに応じた光信号を出力する複数のレーザダイオード、レーザダイオードの数よりも少数チャネルの入力データを受け取り、入力データのチャネル数と同数のレーザダイオードに振り分けるチャネルセレクタ、および、複数のレーザダイオードそれぞれからの光出力をモニタして、チャネルセレクタに、正常なレーザダイオードへ入力データを振り分けさせるモニタを具備する第1の光モジュールと、光信号の受信チャネル数よりも多数の光センサ、多数の光センサのうち受信チャネル数と同数の光センサからの出力信号を信号出力端子に割り当てるチャネルセレクタ、および、光センサそれぞれの出力信号をモニタして、チャネルセレクタに、該光センサのうちの光信号を正常に受光した光センサからの出力信号を信号出力端子に割り当てさせるモニタを具備する第2の光モジュールとを備えた。
