一种产生OCS-DPSK光载毫米波的光纤无线系统

摘要

提出了一种产生载波抑制-差分相移键控(OCS-DPSK)光载毫米波的光纤无线系统.建立了OCS-DPSK光载毫米波的产生和传输链路模型,分析了光纤色散的影响,并通过仿真实验验证了系统的可行性.实验结果表明,重复频率为30GHz的OCS-DPSK光载毫米波调制2.5Gb/s基带信号经80km光纤传输后,眼图清晰可见,功率代价为3.7dB.%Proposed a radio over fiber system with optical OCS-DPSK mm-wave generation. Both detailed theoretical analysis mode model and simulation experiments to demonstrate the feasibility of the proposed system are presented. Experiment result shows that the 2.5Gb/s data carried by 30GHz OCS-DSPK mm-wave can be successfully transmitted over 80km standard single-mode fiber (SSMF) with less than 3.7dB power penalty.
