An optical transmission channel permitting terminal electrical connection with operating characteristics in a very wide frequency band, while maintaining the transfer function constant. It comprises an optical cable terminated at each end by a module containing, for each link, an emitting or receiving diode as a function of the particular case and its associated electronic circuit. The optical coupling is performed by a detachable optical connector within the module and each circuit has a frequency compensating circuit to produce a phase lead and accentuate the high frequencies.

The correlator comprises a piezo-electric substrate on the ends of which there are arranged two transducers supplied with two electrical signals and emitting two contra-propagating surface waves. The correlator furthermore comprises m processing channels supplied with electrical signals induced by the surface waves at m 'points' on the substrate which are distributed in the direction of propagation of the waves. Each channel comprises a non-linear device and an integrator furnishing a sample of the correlation function of the two signals.
