OPTICAL TRANSMITTING APPARATUS FOR MINIMAL DISPERSION ALONG AN OPTICAL FIBER

摘要

A plurality of transmitting signal lights are supplied from a semiconductor laser light source (1) which is modulated by a current having adjusted amplitude and phase injected thereinto in an optical transmitting apparatus (31). The signal lights are modulated in intensity by a plurality of external modulators, (17,18) and a time-difference is applied among the signal lights. Thus, the signal lights are combined to provide a transmitting signal light which is propagated through a transmission line. At this time, a frequency component having a low transmission speed is supplied to the transmission line earlier than a frequency component having a fast transmission speed in compliance with a wavelength dispersion property of the transmission line.
