Popis:	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.
