大连地区FTTH工程设计与实施

第I页大连地区FTTH工程设计与实施摘要在21世纪，随着电子信息技术的迅猛发展，市场需求环境变化，业务多媒体化、宽带化的发展对电信网的适应力要求越来越高。而用户接入网的传统技术手段ADSL已经难以适应这种高速发展的通信需求。该市场领域存在着巨大的市场，在市场潜能的驱动下产生了各式各样的接入网技术。FTTH宽带具有以下特征：通信容量大、质量高并且性能稳定，能够防电磁干扰，同时具有保密性强的优点。在干线通信里，FTTH宽带扮演着十分重要的角色，在接入网中，FTTH宽带的接入也会成为技术发展的重点。FTTH宽带接入是开展宽带接入的长期的发展方案。本设计将结合莲花湾小区的网络现状，在分析FTTH接入网基本构成、分类的基础之上，制定莲花湾小区的FTTH接入网设计方案，其中包括了FTTH接入网设计目标、设计依据、业务需求以及FTTH接入网具体流程等，并对此方案进行了工程实施，在实施过程中解决了现实中的实际性问题，有效提高住户宽带的接入速率，使用户拥有更良好的宽带使用体验。关键词：接入网技术，FTTH，方案设计，工程实施第II页DesignandImplementationofFTTHProjectinDalianAbstractInthe21stcentury,withtherapiddevelopmentofelectronicinformationtechnology,thechangeofmarketdemandenvironment,multimediabusiness,thedevelopmentofbroadbandtelecommunicationsnetworkresilienceandthehigher.Anduseraccessnetworkoftraditionaltechniques,ADSLhasbeendifficulttomeetthecommunicationneedsoftherapiddevelopmentof.Themarketexisthugemarket,drivenbythemarketpotentialproducedhasthefollowingfeaturesavarietyofaccessnetworktechnology.FTTHbroadband:largecommunicationcapacity,highqualityandstableperformance,iscapableofpreventingelectromagneticinterference,alsohasadvantagesofstrongsecrecy.Inthetrunkcommunication,FTTHbroadbandplaysaveryimportantangleColor,intheaccessnetwork,FTTHbroadbandaccesswillalsobecomethefocusofthedevelopmentoftechnology.FTTHbroadbandaccessistocarryoutthelong-termdevelopmentofbroadbandaccess.ThisdesignwillcombinethenetworksituationofLianhuawanneighborhood,ontheanalysisofthebasiccomponentsoftheFTTHaccessnetwork,classificationonthebasistodeveloptheFTTHaccessnetworkdesignschemeofLianhuawanneighborhood,includingtheFTTHaccessnetworkdesignobjectives,designbasis,businessneedsandtheFTTHaccessnetworkspecificprocesses,thisprojectandtheengineeringimplementation,intheimplementationprocesstosolvetherealpracticalproblems,effectivelyimprovethehouseholdbroadbandaccessrates,usershavemoregoodbroadbandexperience.Keywords:accessnetworktechnology,FiberToTheHome,conceptualdesign,engineeringimplementation第III页目录1绪论........................................................................................................................11.1项目建设背景................................................................................................11.2FTTH发展的必需性......................................................................................11.3FTTH国内外发展现状..................................................................................21.4本次设计的主要工作与论文结构.................................................................32光接入网的基本原理................................................................................................42.1FTTH简介......................................................................................................42.2当前主要的几种宽带接入技术比较.............................................................52.3FTTH接入技术的组网方式及适用环境......................................................72.4FTTH中应用到的主要设备..........................................................................82.5PON技术基础..............................................................................................102.6GPON原理与技术.......................................................................................102.6.1GPON工作原理................................................................................102.6.2GPON技术特点................................................................................113莲花湾小区FTTH接入工程设计..........................................................................123.1莲花湾小区情况及设计概述.......................................................................123.2基本建设及设备选型...................................................................................123.2.1局端OLT的选择与节点设置..........................................................133.2.2用户端ONT选择与接入节点设置.................................................143.3光缆设计方案...............................................................................................154莲花湾小区FTTH接入工程实施..........................................................................164.1光缆的选择与安装.......................................................................................164.2分光器的选择与安装...................................................................................164.3用户端ONT调制与业务开通....................................................................184.4各业务可能出现的问题及解决方案...........................................................19结论..........................................................................................................................21致谢..........................................................................................................................22参考文献......................................................................................................................23第IV页附录A外文文献.........................................................................................................24附录B外文翻译.........................................................................................................33第1页1绪论1.1项目建设背景最近几年，高速发展的IP局域网和基于互联网协议的骨干网成为了宽带网络的传输主体。接入网技术作为信息高速公路的“最后一公里”，以其身份成为了全世界接入网用户的
