10 Gbit/s EPON非对称ONU光模块的设计

Design of 10 Gbit/s EPON asymmetric ONU optical modules

文章重点介绍和讨论了10Gbit/s EPON(以太网无源光网络)非对称ONU(光网络单元)光模块的组成和关键技术,特别是发射硬件电路的构成和数字APC(自动光功率控制)的原理,同时,也介绍了接收部分的实现,给出了合理的设计方案且通过实验进行验证。实验结果表明,采用该方案设计出的光模块能满足国际标准要求,可以广泛应用于光通信领域。

This paper focuses on the composition and key technology of 10 Gbit/s EPON asymmetric ONU optical modules,especially on the structure of the emitting hardware circuits and the principle of the digital Automatic Power Control（APC）,introduces the realization of the receiver section and gives a rational design scheme,which is verified in experiments.The results indicate that the optical modules designed in this scheme conform to the requirements of the international standards and can be extensively applicable in the flied of optical communications.
