摘　　要：针对无源光网络(PON)中上行突发信号的特点,从误码率、信噪比和信道利用率3个方面对直流耦合突发模式光接收机和交流耦合突发模式光接收机的性能作了对比分析。并给出了改善突发光接收机信噪比和信道利用率的实现方案,对高速突发接收方案的设计有较好的指导意义。On the basis of the characteristic of uplink burst optical signal of PON system,a comparative analysis between the DC coupled burst mode optical receiver and the AC-coupled burst mode optical receiver was conducted on three aspects：BER,SNR, channel utilization rate.An implementation program was put forward to improve the SNR and the channel utilization rate of the burst optical receiver.The program was a better guide for the high-speed burst receiver design.
