摘要
介绍EPON网络的结构、原理及特点。EPON系统能解决传统井下网络的层叠问题;无源性使它彻底避免外部设备的电磁干扰,降低故障率,同时节省维护成本;此外,EPON还能使地面局域网与井下监控网实现无缝连接,很好解决井下通信距离、速度、成本和安全等问题。
Describes the structure,principles and characteristics of EPON network.It is able to solve the cascade problems in the underground traditional network.Its passive nature makes itself completely to avoid the electromagnetic interference of exterior device,to reduce failure rate,and to improve reliability.Furthermore,EPON is able to realize the seamless communication of underground monitor network with surface local area network,fairly solve the problems of communicating distance,speed,cost and safety underground.
