Abstract
This study propose and demonstrate a directly modulated NTSC AM-VSB 77-channel together with Internet access system by using switched-star architecture, FP laser diodes, single AM- VSB channel transmission, wavelength-division-multiplexing (WDM) and two-way communication techniques over the existed multimode fibers (MMF's) in the campus. Performances of carrier-to-noise ratio (CNR) of > 50 dB, composite second order (CSO) of > 71 dB and composite triple beat (CTB) of > 71 dB were obtained over 0.5 to approximately 2.0 km MMF's transmission. This proposed two-way communication system is simpler and lower cost than the conventional broadcasting fiber optical CATV system.
