摘要：

A hybrid dense-wavelength-division-multiplexing (DWDM) system for CATV, 256-QAM and OC-48 trunking is proposed and demonstrated. It used two wavelengths for AM-VSB CATV, one wavelength for 256-QAM digital passband signals and four wavelengths for OC-48 (2.5 Gb/s) digital baseband signals transport. Good performances of carrier-to-noise ratio (CNR) greater than or equal to 50 dB, composite second order (CSO) greater than or equal to 67 dB and composite triple beat (CTB) greater than or equal to 65 dB were obtained for AM-VSB CATV, and low bit error rate (BER < 10(-9)) had been achieved for 256-QAM and OC-48 digital signals over an 80-km large effective area fiber (LEAF) transport.
