Abstract :
An optical system for the transmission of digital video broadcasting (DVB) signals is proposed and experimentally demonstrated. The transmission media comprises 1-mm diameter graded-index plastic optical fiber (GI-POF) with a relatively high bandwidth. The system is fully engineered using low-cost off-the-self components including a vertical-cavity surface-emitting laser, a silicon avalanche photodiode, POF connectors, and all integrated radio frequency (RF) circuitry. The RF distribution of standard DVB-satellite second generation signals in 950-2150 MHz and DVB-terrestrial signals in 470-790 MHz over 25-m GI-POF is successfully demonstrated.
