摘要/Abstract

摘要：

IEEE已经成立了100 Gbit/s以太无源光网络（100 Gbit/s-EPON）任务组研究下一代100 Gbit/s PON标准，双二进制检测技术是基带技术选择之一。对基于10 Gbit/s-PON接收机的25 Gbit/s双二进制（DB）检测传输性能进行了实验验证。由于10 Gbit/s-PON接收机带宽受限明显，10 Gbit/s-PON接收机输出的25 Gbit/s双二进制信号会受到码间干扰（ISI）影响。实验结果表明，基于直接判决法的系统接收灵敏度只有-22 dBm，采用最简最大似然序列估计（MLSE）软判决法的系统接收灵敏度能提升到-24.5 dBm。

Abstract:

IEEE has formed the 100 Gbit/s-EPON Task Force to develop next 100 Gbit/s-PON standards，and the duo-binary(DB) detection is one of the baseband technology options.25 Gbit/s DB detection transmission performance with 10 Gbit/s-PON receiver was been experimentally demonstrated.Because the bandwidth of 10 Gbit/s- PON receiver is obviously limited,the 25 Gbit/s DB output signal from 10 Gbit/s-PON receiver will be affected by the inter-symbol interference(ISI).The experiment results show that the system receiving sensitivity based on direct decision method is only -22 dBm.However,the system receiving sensitivity can be up to -24.5 dBm by using the most simplified maximum likelihood sequence estimation(MLSE) soft decision method.

Key words: 100 Gbit/s-EPON, duo-binary detection, receiving sensitivity, MLSE
