Abstract

In this paper, we experimentally demonstrated four-channel wavelength-division-multiplex (WDM) 560 Gbit/s 128 quadrature amplitude modulation (128QAM)-Discrete Multi-Tone (DMT) signal transmission in short reach interconnect. Coordinated discrete Fourier Transform-spread (DFT-spread) and pre-equalization are jointly used to simultaneously overcome serious frequency domain power attenuation and reduce the peak-to-average power ratio (PAPR) of the DMT signal. An additional post decision-directed least mean square (DD-LMS) equalizer is used afterward to further compensate the channel response and mitigate the devices' implementation penalty. These proposed algorithms and equalizer are validated through experiment in this paper, we achieved highest capacity signal transmission in four-channel WDM transmission system using intensity-modulation and direct-detection (IM/DD) over 2.4-km single mode fiber (SMF) with bit-error-ratio (BER) under the hard-decision forward error correction (HD-FEC) limit of 3.8×10^{-3}.
