摘要
随着网络可靠度要求的不断提高和光纤设备成本的不断降低,FTTH将成为未来接入网唯一的选择,PON(Passive Optical Net,无源光网络)技术因为其便于实现、成本低廉的特点得到广泛的应用,同时已经被公认为解决"光纤入户最后一公里"问题的最佳方案。详细介绍了"光速城市"中OLT的部署。
Along with the continuous increase of the requirement for the network reliability and the continuous decrease of the cost of fiber-optic equipment, FTTH will become the only choice of the access network in the future. The PON（passive optical network）technology has been widely applied because of its facilitated fulfillment and lower cost, and is known as the best scheme of solving the problem of the last kilometer of fiber-to-the-home. This paper introduces in detail the deployment of OLT（Optical Line Terminal）in ray city.
