ABSTRACT:
An optical signal transmission device which includes a number of laser diodes each having a different oscillating wavelength and a number of exclusive external modulators are provided based on the number of laser diodes for receiving corresponding outputs of the respective laser diodes and modulating output lights of the laser diodes by separate electrical signals. Also included is an optical coupler device for coupling the optical signal outputs of the external modulators therebetween and an optical amplifying unit for amplifying the output of optical signals of the optical coupler device. The modulated optical outputs of the external modulators are delivered to an optical fiber transmission line in a time-series-mode.
