High speed dense wavelength division multiplexing atmospheric laser communication system

摘要

We demonstrated a high speed atmospheric laser communication system based on a two channels dense wavelength division multiplexing, and 10Gb/s non return to zero sequence and 10GHz sine wave are modulated on the channels respectively. The channel spacing is 100GHz and the experimental distance is over 1km. The experimental results show that this dense wavelength division multiplexing system can realize the high speed information atmospheric transmission.
