<p>The invention relates to a wide-band optical transmission device for a plurality of transitory analog signals. This device comprises (N-1) wide-band analog delay lines consisting of stretches of optical fibre (Fb2 to Fb4) of different length and in which (N-1) of the transitory signals are conveyed by way of optical emitters (32 to 34, 52 to 54) respectively. An optical coupler (25), an optical receiver (Ro1) and an electric switch (41) make it possible to multiplex over time the delayed signals and the undelayed signal. The multiplexed signal is transmitted via a single optical fibre link (35 to 39, Fb1). Interrupters (42 to 44) make it possible to avoid any overlapping of the multiplexed signals. The invention applies in particular to the analysis of transitory phenomena such as lightning, electromagnetic pulsing etc. <IMAGE></p> |
