Patent ID: 11075541

Abstract:
A signal transmission system comprises: a power supply, a power sourcing device and a powered device connected to each other through a coaxial cable; the power sourcing device comprises a first active inductor module for receiving a DC signal transmitted by the power supply, and transmitting the DC signal to the powered device through the coaxial cable, a first capacitor module for receiving a superposed signal transmitted through the coaxial cable, and transmitting the superposed signal to a signal processing module; and the powered device comprises a second active inductor module for receiving, through the coaxial cable, the DC signal, and transmitting the DC signal to a signal acquiring module for acquiring a superposed signal, a second capacitor module for transmitting the superposed signal to the power sourcing device through the coaxial cable, and the signal acquiring module is for transmitting the superposed signal to the second capacitor module.
