摘　　要：正交频分复用(Orthogonal frequency division multiplexing,OFDM)因其频谱利用率高,被广泛应用于无线通信系统。利用少模光纤(Few Mode Fiber,FMF)和模分复用(Mode Division Multiplexing,MDM)技术,结合OFDM调制,可实现室内高速光接入。通过Matlab和OptiSystem联合仿真,利用四种模式,每种模式传输25 Gb/s的数据,实现了100 Gb/s数据传输系统。在误码率小于-2.3 dB条件下,输入电信号功率动态范围约为10 dB。Orthogonal Frequency Division Multiplexing(OFDM)is widely used in wireless communication systems because of its high spectrum utilization.The use of Few Mode Fiber(FMF)and Mode Division Multiplexing(MDM)technology combined with OFDM modulation enables high-speed indoor optical access.Through the joint simulation of Matlab and OptiSystem,using four modes,each mode transmits 25 Gb/s of data,realizing a 100 Gb/s data transmission system.At a bit error rate less than-23 dB,the input electrical signal power dynamic range is approximately 10 dB.
