Many advantages make optical fiber suitable used as transmission medium of high - rate broadband services , such as broad transmission band , large capacity , low loss , strong immunity to interference etc . among optical access network , passive optical network ( pon ) is paid more attention throughout the world . it offers easily upgraded and low cost of lay , ope ration and maintenance . especially passive optical network based on atm ( atm - pon ) integrates the capability of supporting multiple qos services with atm and transparent transmission with pon
在光纤接入网中，无源光网络( pon )由于不采用有源节点、敷设和运行维护成本低且成本共享、对业务透明、易于升级等优点而备受世界各国的关注，特别是以atm为基础的无源光网络( atm - pon ) ，由于结合了atm多业务、多比特率的支持能力和pon的透明宽带传送能力，将成为实现未来宽带接入乃至最终实现ftth的重要方式。
