城域光接入网工程设计资料.docVIP

摘 要 的题目是“城域光接入网工程设计”，是通过光纤通信完成本地用户业务接入，属光纤接入网工程范畴。 光纤通信具有传输容量大、传输损耗小、不怕电磁干扰等优点广泛应用于干线传输。在城域网和局域网中，目前光纤通信已发展到路边FTTC，到大楼FTTB，到用户FTTH。光纤通信在通信传输系统中占有越来越重要的位置。在世界范围内得到迅猛的发展和广泛地应用，并在人们心中享有很高的声誉。 本工程为华光园小区接入工程设计。锦州电信城域网光传输环：锦州中心机房——华光园小区接入点。 设计目的是为华光园小区安装1536个语音信号、个ADSL用户等，并考虑满足该小区远期业务增长的需求。设计包括综合接入网设备ONUF02A、传输设备OptiX155/622H及其他配套设备的安装设计。设计做到技术先进、经济合理、安全适用，并充分利用原有设施，避免重复建设。 关键词：接入网；光缆；SDH同步数字系列；ONU光网络单元 Abstract title of the dissertation is “The Design of Metropolitan Optical Access Network Engineering”, which can make the user access by using fiber communication. It belongs to the project of Fiber Access Network. Fiber communicating has the character of big capacity of delivering, low delivering cost, not being interrupted by electronics and magnetic field. So this technique is being used widely in main line communicating. In city’s network and local network, up to now the fiber communicating has developed into FTTC (Fiber to the curb) and FTTB (Fiber to the building) and FTTH (Fiber to the home) .The fountain of fiber communicating is more important. In the world, this technique has been improved and used widely so it has very good reputation among users. This project for Hua Guangyuan plot turning on engineering design. Jinzhou use of optical telecommunications MAN ring, ONU (optical networking unit) OAN Services Access Centre, OLT (optical line terminal).Jinzhou center engine room - - Hua Guangyuan plot junction point. The design goal is the plot installs 1536 voice signals, 80ADSL users for Hua Guangyuan and so on, and considered that satisfies this plot forward service aggregate demand.The design includes optical integrate access network equipment ONUF02A(optical network unit), transmission equipment OptiX155/622H and other relating equipment to finish the project. The technique of the design must be advance, economical, safe, usable, using old equipments as possibly as and avoiding rebuilding.
