Abstract: A novel 1.28Tbps dense wave length division multiplexing system for free-space optical communication is proposed here. It is a line-of-sight system and uses novel coherent optical quadrature phase shift keying (QPSK) modulation technique. The system consists of 32-channels with bit-rate of 40-Gbps/channel and adjacent channel spacing of 200GHz. The system is analyzed for various modulation formats such as return-to-zero, non-return-to-zero and coherent optical QPSK modulation technique. The performance of the proposed system is analyzed in terms of bit error rate, Q-factor and eye opening etc. For an input power level of 10dBm, the coverage distance observed for the system is 1360km, for coherent optical QPSK modulation technique. � 2012 IEEE.
