Kind Code:
A1
Abstract:
Provided is a transmission system for transmitting data, which comprises: a modulating unit that modulates the amplitude of a predetermined carrier signal in accordance with data to be transmitted; an electro-optic conversion unit that converts the modulated signal outputted by the modulating unit to an optical signal; an optical fiber used for transmitting the optical signal; an opto-electric conversion unit that converts the optical signal transmitted by use of the optical fiber to a current signal; a current-to-voltage conversion unit that linearly converts the current signal to a voltage signal; and a demodulating unit that demodulates the voltage signal.
