摘要： An optical repeating device with a monitoring function comprises first optical propagation means for propagating a lightwave signal through an optical transmission line, second optical propagation means butted against the first optical propagation means, for propagating the lightwave signal, optical branching means provided on a butting face between the first optical propagation means, and the second optical propagation means, and photodetection means. All the means described are assembled into a housing, and integrated therewith. Consequently, it is possible to downsize the optical repeating device with the monitoring function. A large portion of the lightwave signal propagated between the first optical propagation means and the second optical propagation means is allowed to pass through the optical branching means, however, a portion of the lightwave signal is reflected in a given direction by the optical branching means. A lightwave signal reflected is detected by the photodetection means, and is converted into an electric signal. When the electric signal as converted is displayed by, for example, display means, it is possible to check visually whether or not the lightwave signal is transmitted through the optical transmission line.
