Paper Abstract

Single-carrier frequency domain equalization (SC-FDE), as a mature technique in wireless commutation, is widely researched for signal equalization and compensation utilizing high speed electronic devices such as DSP. In this paper, for the first time, we propose and demonstrate a SC-FDE technique in optical communication system. By adopting SCFDE technique, after 50km, 80km, 100km transmission for a 10Gb/s ASK single sideband (SSB) signal on a single mode fiber (SMF), the dispersion of optical signa1 is effectively compensated. The SSB signal is generated by a dual-arm Mach-Zehnder modulator (MZM) cascading a phase modulator (PM) based on Hilbert Finite impulse response (FIR) digital filter. The results demonstrate, in our proposed SC-FDE model, the eye opening and the clock recovery is improved, and the effect of compensation is enhanced as the transmission distance increases.
