FIBER OPTIC DIGITAL TO ANALOG CONVERTERS Russian patent published in 2016 - IPC H03M1/00 

FIELD: computer engineering.

SUBSTANCE: invention relates to means of automation and computer engineering, for example, in the system control objects. Fiber optic-analog converter comprises reference voltage source 1, radiator 2, transmitting optical fiber 3, optical demultiplexer 4, first group of optical fibers 5, 6 selfocs group focusing optical attenuators based on slit diaphragms 7-10 Porro prism 11, group of shutters 12, selfoc collimating group 13, second group of optical fibers 14, optical multiplexer 15, receiving optical fiber 16, photodetector 17, photoamplifier 18, analog-to-digital converter 19.

EFFECT: technical result is to increase the reliability of the inverter due to one-sided arrangement of elements emitting and receiving channels with respect to the multiplexing element.
