Hybrid wavelength-division-multiplexing systems for high-capacity digital and analog video trunking applications

摘要

A five-channel hybrid wavelength-division-multiplexing (WDM) system with one AM-VSB channel and four 2.5 Gb/s channels was demonstrated for video trunking and distribution applications. Two erbium doped fiber amplifiers (EDFAs) with saturated output power of +13 dBm were used for a standard single mode fiber span of 100 km. Error-free transmission for the digital channels and a carrier-to-noise ratio (CNR) higher than 50 dB for the AM-VSB channel could be achieved simultaneously.
