Abstract
The optical fiber transmission of audio and video signals using the pulsewidth modulation (PWM) technique is proposed and experimentally verified. The PWM signal is clocked at 12 MHz or at 14.32 MHz and then converted into the optical pulse. The optical pulse at 850 nm is generated by using a light-emitting diode (LED), transmitted through an optical fiber of up to 2-km long, and received by a p-i-n photodiode (PIN-PD). The differential gain (DG) and differential phase (DP) are under 5% and 5°, respectively, and the SNR was above 45 dB
