TRANSMISSION OF AUDIO SIGNALS VIA FIBRE OPTIC

摘要

A system received an analogue electrical signal having content between 20 Hz and 20 kHz representing an analogue audio signal; amplitude modulates the analogue electrical signal onto an optical signal; transmits the modulated optical signal over an optical waveguide; receives. The modulated optical signal; and demodulates the modulated optical signal to reproduce the analogue electrical signal. The system may be incorporated within a cable arrangement.
