| 摘要 |
<p>The invention relates to a self-heterodyning optical transmission method and a transmission system with switching matrix implementing the method. The method consists in transmitting optical signals to one or more receiver appliances (F11, F1N) among N, from optical transmission means (90) comprising means (10) of emitting optical signals, means (20) of modulation by frequency transposition, and an optical fibre link (90). It further consists: - in transmitting a given signal on one or more carrier frequencies towards respectively one or more receiver appliances, - in obtaining the carrier frequency or frequencies by transposition of an emission frequency by means of separate control signals which can be selected as a function of the receiver appliance or appliances, - in transmitting, on the same optical link, the emission frequency signal. Application to optical transmission of signals by frequency switching. <IMAGE></p> |
