FIELD: radio equipment.
SUBSTANCE: invention relates to radio engineering and sonar and can be used in hydroacoustic equipment for receiving weak hydroacoustic signals. Optical wavelength range and a set of fiber-optic components are used to filter electric signals: transmitting and receiving optoelectronic modules, optical splitters / couplers and fiber-optic delay lines.
EFFECT: technical result consists in improvement of reliability, efficiency of filtration and expansion of operating frequencies range.
