160 Gbit/s soliton transmission in the S and C bands

Abstract

We present for the first time results of soliton transmission in the S-band. We performed computer simulations of single channel solitonic communication systems at 80 Gbit/s and 160 Gbit/s, in the Quasi-Adiabatic regime, in the S and C bands. For the S band we employ non-zero dispersion shifted fibers (NZDSF) and thulium doped fiber amplifiers (TDFA) in the optical communication system. For the C band we use dispersion shifted fibers (DSF) and erbium doped fiber amplifiers (EDFA). We present eye diagrams and bit error rates for these configurations and we show that soliton transmission in the S band is just as feasible as in the C band, without the use of dispersion management techniques. We also show the effect of two essential elements in the system, the optical bandpass filter and the soliton amplitude modulation.
