随着宽带用户的增长及各种新兴需求服务的崛起,宽带应用在各个领域加速渗透。据Forrester Research估计,在今后两年里有一半的企业用户打算将带宽增加一倍。那么这种带宽从何而来呢?光纤是解决这一问题的答案。(一)光纤接入网光纤接入网(OAN)是消除阻挡在局域网和广域网中不断增加的容量之间瓶颈的实用技术。OAN使服务提供商可以向各种规模的企业提交基于光纤的宽带服务。基于无源光学网络(passive optical network,PON)的
With the growth of broadband users and the rise of various emerging demand services, broadband applications accelerate penetration in all fields. Forrester Research estimates that half of enterprise users plan to double their bandwidth over the next two years. So where does this bandwidth come from? Fiber is the answer to this problem. (I) Optical Access Network The optical access network (OAN) is a practical technique to eliminate the bottlenecks that block the ever-increasing capacity in LANs and WANs. OAN enables service providers to deliver fiber-based broadband services to businesses of all sizes. Based on passive optical network (PON)
