摘要

CATV（有线电视）网是高效廉价的综合网络，它具有频带宽，容量大，多功能、成本低、抗干扰能力强、支持多种业务连接千家万户的优势，它的发展为信息高速公路的发展奠定了基础。就我国最近几年CATV网发展来看，全国已建有线电视台超过1500座，用户数达8000多万，在全国覆盖面达50%，并且每年仍以30%的速度增长。电视机已成为我国家庭入户率最高的信息工具之一，CATV网也成最贴近家庭的多媒体渠道，只不过它目前还是靠同轴电缆向用户传送电视节目，还处于模拟水平。宽带双向的点播电视(VOD〕及通过CATV网接入Internet进行电视 点播、CATV通话等是CATV网的发展方向，最终目的是使CATV网走向宽带双向的多媒体通信网。
本课题的目的是掌握CATV光纤网络工程方案，设计缙云县CATV网络乡镇节点图。熟悉相关技术标准和规范，对光功率分配和技术指标的分配会予以计算，绘出网络配置图、节点技术指标参数表及器材清单。

Summary

The CATV(cabled T.V.) net is an efficiently cheap comprehensive network, it has a Pin bandwidth, have great capacity, multi-function, the cost be low, the anti- interference's ability be strong, support various business conjunction thousand is ten thousand door advantages, it of the development lay foundation into the development of information superhighway.In regard to the our country last few years CATV net development, the whole country has already set up cable television station more than 1500, the customer number reach to 8000 have another ten thousand, overlay noodles to reach to 50% in the whole country, and still increase by 30% speed annually.The television has become an our country a family one of the information tools with tallest rate into the door, the CATV net also becomes to come close most homely of multi-media outlet, only it still depends coaxial cable to deliver television program toward the customer currently and also be placed in emulation level.The breadth takes a double to of order and sow television(VOD]and connect into Internet to carry on a television point through a CATV net sow, the CATV converse etc. is a CATV net of development direction, end purpose is make CATV net alignment the breadth take a double to of the multimedia correspond by letter a net.
The purpose of this topic controls CATV fiber-optic network engineering a project, the design Jin network village of the cloud county CATV node diagram.Acquaint with related technique standard and norm, will give a calculation to the allotment of light power allotment and technique index sign, draw a network allocation diagram, form and device detailed list of the index sign parameter of the node technique.

The purpose of this topic controls CATV fiber-optic network engineering a project, the design Jin network village of the cloud county CATV node diagram.Acquaint with related technique standard and norm, will give a calculation to the allotment of light power allotment and technique index sign, draw a network allocation diagram, form and device detailed list of the index sign parameter of the node technique.

Answer 3

CATV (cable TV) the net is the highly effective inexpensive comprehensive network, it has the band width, the capacity is big, multi-purpose, cost low, antijamming ability strong, support many kinds of service connection everyone's superiority, its development has laid the foundation for the information superhighway development.Looked on our country recent several year CATV net development that, the nation has constructed the wired television station to surpass 1500, the number of users reaches 8000 ten thousand, reaches 50% in the national coverage, and every year still by 30% speed growth.The television has become one of our country family residence rate highest information tools, CATV net also Cheng Zui draws close to the family the multimedia channels, it at present depends on the coaxial cable to the user transmission television program, but also is in the simulation level.Wide band bidirectional selection and broadcast television (VOD) and turns on Internet through the CATV net to carry on the television selection and broadcast, the CATV telephone conversation and so on is the CATV net development direction, the final goal is causes the CATV net to move towards the wide band bidirectional multi-media net.

Answer 4

The CATV( cabled T.V.) net is an efficiently cheap comprehensive network, it has the bandwidth of 频 , have great capacity, multi-function, the cost is low, the anti- interference ability is strong and supports ten thousand doors advantages of various business conjunction thousand, its development lay the foundation into the development of the information superhighway.In regard to our country most in the last few years CATV net development, the whole country has already set up the cable television station over 1500, the customer number amount to 8000 many ten thousand, overlay to face to amount to 50% in the whole country, and still increase with 30% speed annually.The television has become the our country family to go into one of an information tools with tallest rate, the multi-media outlet that CATV net also becomes to come close most the family, only it still depends the coaxial cable toward customer to deliver the television program currently, still being placed in the emulation level.The breadth takes the double to of order and sow television( VOD] and pass the CATV net connects into the Internet to carry on television's order to sow, converse etc. of CATV is a CATV net of development direction, end purpose is make the multimedia correspondence net that the CATV net alignment breadth takes double is.
The purpose of this topic is to control the CATV fiber-optic network engineering project, the design 缙 cloud County CATV network village node diagram.Acquaint with the related technique standard and norms, will give the calculation to the allotment of the light power allotment and the technique index sign, draw a network to install the diagram, the node technique index sign parameter form and device detailed lists.
