Abstract :
In this paper, we propose a generalized hybrid subcarrier/amplitude/phase/polarization (GH-SAPP) modulation based free-space optical (FSO) communication network. By using 32-GH-SAPP modulation and mature 10 Gb/s technology the aggregate rate of 110 Gb/s can be achieved, which represents an FSO scheme compatible with 100G Ethernet. The 32-GH-SAPP coded-modulation scheme can operate even under strong atmospheric turbulence regime while still carrying 100G traffic. The corresponding polarization-multiplexed 16-QAM scheme can only operate under weak turbulence regime with aggregate data rate of only 80 Gb/s. The proposed scheme represents a cost effective solution to current high-bandwidth demands.
