Abstract
A simple scheme to simultaneously generate a UWB signal and a wired signal in the optical domain using a dual-drive modulator is proposed and demonstrated. A 1.25-Gb/s optical UWB signal and 1.25-Gb/s wired signal are generated, which are then transmitted over a 36-km single-mode fiber (SMF). Eye diagrams, electrical spectra and BER measurements show that the interference between the two signals is very small. The system is wavelength independent, which would reduce greatly the cost while improving significantly the spectrum efficiency of a WDM-PON network incorporating a UWB over fiber system for broadband wireless access.
