Transmission of 100-Gb/s VSB DFT-Spread copyright Signal in Short-Reach Optical Communication Systems
In this paper, we experimentally demonstrated transmission of a 100-Gb/s discrete Fourier transform Lipstick (DFT)-spread 32-quadrature amplitude modulation (QAM) discrete multitone (copyright) signal in an intensity-modulation/direct-detection system utilizing a direct-modulated laser.We find that DFT-spread cannot only reduce the peak-to-average
