| 摘要 |
<p>The invention relates to the transmission over an optical fibre (107) of the electrical signals arising from sensors (101). It consists in using a source (102) with small coherence length and a modulator (105) with large optical path difference. A demodulator (108) identical to the modulator is used for demodulation. It enables signals with a dynamic range of at least 80 dB to be transmitted over a distance greater than 1 km. <IMAGE></p> |
