Paper Abstract

A directly modulated 1.3-?m 77-channel AM-VSB video and 63-channel simulated 256-QAM digital signals lightwave long-haul transmission system using a praseodymium-doped fiber amplifier (PDFA) and split-band and wavelength-division multiplexing (WDM) techniques is demonstrated. A high system performance of carrier-to-noise ratio (CNR) >50 dB, composite second order (CSO) >65.5 dB, and composite triple beat (CTB) >64 dB for AM-VSB is obtained, accompanied with carrier-to-noise and nonlinear distortion ratio (C/(N + NLD))>38 dB for 256-QAM.
