We propose a compact integration system to simultaneously provide wireline and wireless [baseband and ultra-wideband (UWB)] services to end-users in a wavelength-division-multiplexed-passive optical network (WDM-PON). A 1-Gb/s UWB signal is optically generated and shares the same wavelength with the baseband signal. Error-free performance was achieved after 23-km single-mode-fiber (SMF) transmission for both signals and additional 0.4-m wireless transmission for the UWB signal. The low complexity and high spectrum efficiency of this system makes it attractive for deployment of in wireline/wireless converged gigabit optical access networks.
