7.5Gbps 40 km horizontal path DWDM optical link experiment

Based on DWDM and EDFA technology, 7.5 Gbps free space laser communication demonstration system was developed. Experiments of 7.5 Gbps 40km free space laser communication were completed in Qinghai lake Qinghai province on the Aug. 2010.Error free communication was achieved at the speed of 155 Mbps, and 10-7 BER was achieved at the speed of 2.5Gbps, 5Gbps and 7.5Gbps test with BER of 10-8~10-7 and 10-7 ~ 10-6 were completed. Laser atmospheric propagation experiments were conducted and analyzed.
