摘要
当今的通信方式是以光纤通信为主，微波、卫星通信为辅的基本格局。也正因如此，光纤通信的发展显得越发重要。
随着互连网技术的普及应用，加之由于经济的迅速发展，人们对通信的需求更加强烈，这要求光纤通信向着大容量，高速率，远距离方向快速发展。光网络的发展又使得光缆的新结构不断涌现 ，新一代的全光网络要求光缆提供更宽的带宽、容纳更多的波长、传送更高的速率、便于安装维护、使用寿命更长等。由此光缆的种类也越来越多，对于特殊环境的地方更有特种光缆来满足特殊的要求。
随着中央政府加大对城镇经济的扶持和投资，安徽马鞍山的经济得到快速发展，城镇居民的富裕度得到迅速的提高，人们在生活、商贸、工作中对移动通信的需求越来越大，对通信质量要求也越来越高；因此安徽通信服务公司本着回报社会的态度，决定加大对城镇的资金投入，扩大信号覆盖面，为城镇的经济发展服务，于是提出了当涂基站接入网二期工程。
根据通信光缆线路工程设计规范，在同一地区的不同地段，对于光纤和路由的选定、敷设都是不同的，根据具体的现场情况和经济要求做出正确的、合理的选择，是保证光纤通信的长期、稳定和安全工作的前提。对于光缆的敷设也有各种具体的要求，同样保证光纤通信的正常工作。系统的调试开通与验收，后期的维护都是光缆工程必不可少的工作。

ABSTRACT
Today's communication is based on optical fiber telecommunications, microwave and satellite communications supplemented pattern.For this reason, the development of optical communication is becoming more and more important.
As international Internet and other information technologies widely used, And because of the rapid economic development, for the communications needs of more intense, require fiber communication toward large-capacity, high-speed, the rapid development of long-range direction. The development of optical network cable also makes the new structure will continue to emerge. The new generation of all-optical cable network requirements for wider bandwidth to accommodate more wavelengths and higher transmission rate, ease of installation and maintenance, such as longer life expectancy.This type of cable is also tending to diversify ,for some special environment more special cable to meet special requirements.
With the support of the central government of town economy and investment, the Anhui Maanshan’s economic have got rapid development, Rich degree of the residents are improved rapidly, people in life, business, work on the Mobile Communication growing demand for quality communications are increasingly high requirements; Therefore Anhui communications services company in return society's attitude and decided to increase their investment in town areas and expand signal coverage, for the people in the economic development of services, and the second project about villages such as TaQiao. Optical Cable Design Research shows that in the same area lots, and fiber routing selection, installation is different, according to the specific circumstances and the economy, the demand to make a correct and reasonable choice is the guarantee of optical fiber communications system long-term, stable, safe working premise. Cable installation for a variety of specific demands, and also assue optical fiber communications normal work. Debugging system opened and accepted later, the cable maintenance works are essential to the work.
Key words：Fiber optic cable circuit，Fiber optic，The engineering design，Budgetary Estimate and Budget.
