| description | PROBLEM TO BE SOLVED: To provide a transmission device capable of identifying a location where a fault occurs, and a fault detection method.SOLUTION: A transmission device comprises: a first output part connected to a second transmission line and a third transmission line which are branched from a first transmission line, and to a fifth transmission line and a sixth transmission line which are branched from a fourth transmission line, and configured to output a first signal light to the second transmission line; a second output part configured to output a second signal light to the sixth transmission line; a third output part configured to output an inspection light of which the wavelength is different from those of the first signal light and the second signal light, to the third transmission line and the fifth transmission line while splitting the inspection light with different powers; and an identification part for identifying a location where a fault occurs, based on powers of reflection lights of the inspection light inputted from the second transmission line, the third transmission line, the fifth transmission line and the sixth transmission line.SELECTED DRAWING: Figure 8
【課題】 障害の発生箇所を特定することができる伝送装置及び障害検出方法を提供する。【解決手段】 伝送装置は、第１伝送路から分岐した第２伝送路及び第３伝送路と、第４伝送路から分岐した第５伝送路及び第６伝送路とに接続されており、第１信号光を前記第２伝送路に出力する第１出力部と、第２信号光を前記第６伝送路に出力する第２出力部と、前記第１信号光及び前記第２信号光と波長が相違する検査光を前記第３伝送路及び第５伝送路に異なるパワーで分岐して出力する第３出力部と、前記第２伝送路、前記第３伝送路、前記第５伝送路、及び前記第６伝送路からそれぞれ入力される前記検査光の反射光のパワーに基づき障害の発生箇所を特定する特定部とを有する。【選択図】図８ |
