摘　　要：比较了无源光网络(PON)中使用滤波器组多载波(FBMC)技术和正交频分复用(OFDM)技术的传输性能。与OFDM调制方案相比,FBMC传输技术由于其较少的相邻信道泄漏而表现出更好的性能。在光通信仿真软件Optisystem中使用Matlab协同仿真,对比了不同条件下的仿真结果。在长度为20 km单模光纤(SMF)传输中,25 Gb/s的误码率(BER)提高约1 dB。可见,FBMC技术具有更好的传输性能,更适用于光通信系统中的宽带传输。Comparison is done on the transmission performance respectively by using FBMC （Filter Bank Multi-Carrier） technology and OFDM （Orthogonal Frequency Division Multiplexing） technology in PON （Passive Optical Network）. Comparison with OFDM modulation schemes, FBMC transmission teehnique exhibit better performance for its less adjacent channel leakage. Matlab co-simulation in the optical communication simulation software Optisystem is done, and the simulation results under different conditions compared. In a 20 km long SMF （Single Mode Fiber） transmission, the BER （Bit Error Rate） of 25 Gb/s is increased by approximately 1 dB. This indicates that the FBMC technology has better transmission performanee and is more suitable for broadband transmission in optical communication systems.
