| Abstract: | A directly-modulated amplitude modulation-vestigial sideband (AM-VSB) cable television (CATV) erbium-doped fiber amplifier (EDFA)-repeated system that uses split-band technique and photonic crystal fiber (PCF) as a broadband dispersion compensation device is proposed and demonstrated. In contrast to a conventional externally-modulated fiber-optic CATV system, good performance of carrier-to-noise ratio (CNR), composite second order (CSO) and composite triple beat (CTB) were obtained in our proposed systems over a combination of 100-km single-mode fiber (SMF) and 3.6 km PCF. |
