Abstract

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) ≥ 50 dB, composite second order (CSO) ≥ 67 dB and composite triple beat (CTB) ≥ 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.
