在以太无源光网络(EPON)系统中,协议规定了最长传输距离不超过20km。但是在某些应用中,光纤线路的距离需要到达几十千米。文章探讨了长距离EPON的实现方法:通过对EPON系统的物理层和多点媒体访问控制(MPMC)子层的部分修改可以实现所需的传输距离。
In an Ethernet Passive Optical Network (EPON) system, the protocol stipulates that the maximum transmission distance does not exceed 20 km. However, in some applications, the distance of optical fiber lines needs to reach tens of kilometers. This paper discusses the implementation of long-range EPON: The required transmission distance can be achieved by partial modification of the physical layer of the EPON system and the multi-layer media access control (MPMC) sublayer.
