PON技术在光纤网络中的应用与研究

Application and Research of PON Technology in Optical Fiber Network

光纤网络利用光波承载数据信息,可以为互联网应用提供更高的带宽,取代了传统的以铜线为传导介质的通信电缆.光纤网络是一种无源网络,为了提高互联网管理效率和改进传输速率,通信学家提出了PON网络,并且在此基础上诞生了BPON、EPON、GPON等光纤网络管理模式,优化了光网通信组网结构,进一步确保光纤网络通信的安全性.本文详细地分析了PON技术的应用发展现状,同时归纳了PON技术在光纤网络设计时采用的模式,重点描述了网络设计采用的关键技术,包括动态带宽资源分配、多点仿真及控制协议等内容.

Fiber optic networks use light waves to carry data information, Can provide more bandwidth for Internet applica- tions, replacing the traditional copper wires as transmission medium of communication cables. Optical fiber network is a passive network, in order to improve the management efficiency and improve the transmission rate of the Internet, communication ex- perts put forward the PON network, and on the basis of the birth of BPON, EPON, GPON optical network management model. Ol^timized optical network communication network structure, to further ensure the safety of fiber optic network communications. This paper analyzes the application situation of PON technology, and summed up by PON technology in optical network design model, describes the key technology of the network design, including the contents of dynamic bandwidth allocation, multi point simulationand control protocol.
