TELECOMMUNICATIONS CARD FOR SECURE OPTICAL DATA TRANSMISSION AND INSTALLATION METHOD

摘要

A card (1) for transmitting data over at least one optical fiber includes a transmitter (10) having at least one light source (12) and a phase modulator (16) for phase modulating light from the source so as to create phase-modulated optical signals in the light as a function of an input electronic data stream; and a receiver having an interferometer for reading received optical signals.
