Abstract
A hybrid dense-wavelength-division-multiplexing (DWDM) system for CATV, 256-QAM and OC-48 trunking is demonstrated. It used two wavelengths for AM-VSB CATV, two wavelengths 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) >64 dB and composite triple beat (CTB) >63 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.
