The long-haul and low-cost chaotic optical secure communications with 1.25 Gbits/s-message and 2.5 Gbits/s-message are experimentally realized using discrete optical components, and the transmission distance reaches 143 km and 25 km, respectively. The former is the longest transmission distance for the chaos-based optical secure communication equipment in the world to the best of our knowledge.
