Optical-microwave transmission system with subcarrier multiplexing for industrial measurement systems

Abstract

We describe short-distance three-channel optical-microwave link with subcarrier multiplexing for transmission digital and/or analog data between different points of industrial measurement systems. The optical fiber link operates with Fabry-Perot laser at 1300 nm, multimode fiber and PIN photodiode receiver. From microwave point of view three carriers with frequencies 600 MHz, 800 MHz and 1000 MHz were chosen. The structure and main parameters of a link are reported and discussed.
