- Abstract
The design and results of studies of a fiber-optic-link-based transmission system for transmitting analog signals of nanosecond duration using an external modulation of radiation are presented. Experimental studies that were performed at the Dukhov All-Russia Research Institute of Automatics demonstrated a method for determining the transmission function of an intensity modulator, which is based on the Mach-Zehnder interferometer, simultaneously with the signal transmission. The dynamic range of the system with one intensity modulator is ~70 when recording a single-shot process. The dynamic range of the transmission system with two modulators that form two information channels exceeds 200 with a bandwidth that exceeds 4 GHz and a signal-to-noise ratio of at least 5 for the minimum recorded signal.
