课程名称：光纤网络设计与维护 课程概述：光纤技术员目前需求量大，光纤网络设计与维护领域的职业发展机会十分广阔！欢迎进入光纤的精彩世界！成功完成本课程后，学生将能够使用光时域反射计（OTDR）定位故障和测量光缆距离，使用熔接机修复光纤链接，进行光纤链接的功率预算和上升时间预算，检查系统的可行性并找出光纤链接支持的最大数据传输速率。 课程分为两个模块： 模块一：光学链接设计简介 - 功率预算概念 - 功率预算案例研究 - 上升时间预算概念 - 上升时间预算案例研究 模块二：光学仪器及光学链接维护简介 - OTDR基础知识 - OTDR演示 - 熔接机基础知识 - 熔接机演示 模块一的学习目标： - 分析在简单的光纤点对点链接中发射器和接收器之间的信号失真，考虑衰减和脉冲色散。 - 对于给定的数据传输速率，定性估计最大传输距离L。 - 定量描述信号检测过程，并定义特定类型信号失真的最小可探测光功率，以满足检测误差标准。 - 理解光学系统组件的典型规格和应用。 光纤用于长距离传输信息，光纤系统在长途数据传输中已大幅取代无线电发射系统，广泛应用于电话、互联网流量、高速局域网（LAN）、有线电视（CATV）等领域，并日益用于建筑物内的短距离传输。光纤的数据传输能力巨大：单根石英光纤可以承载数十万个电话信道，光纤电缆对电缆常见问题（如接地循环或电磁干扰）具有免疫能力。光纤网络是今天和未来的发展趋势，因为其提供了惊人的数据传输速率。通过本课程的第一个模块，学生将成为链接设计的专家。 模块二的学习目标： - 研究故障排除仪器：光时域反射计（OTDR）和熔接机。 - 使用OTDR和熔接机分析和修复光纤网络中的故障。 本模块讨论了光学链接维护的重要仪器，并通过在线演示，让学生获得实践经验，学习如何使用这些设备进行网络维护。
Fiber Optic technicians are in high demand right now and bright career in Fiber Optic Network Design and Maintenance is just waiting for you!Welcome to the exciting colourful world of Fiber Optics!After successful completion of course students will be able toUse OTDR to locate the fault & measure distances of cables.Use Fusion Splicer to repair the fiber optic linksPerform the power budget & Rise time budget for fiber optic linkCheck feasibility of system and find maximum data rate supported by fiber optic linkCourse is divided in to two modules:Module 1:Introduction to Optical Link DesignPower Budgeting ConceptPower Budget case studyRise time budget ConceptRise time budget case studyModule 2:Introduction to Optical Instruments and Maintenance of Optical LinkOTDR BasicsOTDR DemoFusion Splicer BasicsFusion Splicer DemoLearning Objectives of Module 1 are:Analyze signal distortion between transmitter and receiver in a simple fiber-optic point-to-point link with respect to attenuation and pulse dispersion.Do a qualitative estimation of the maximum transmission distance L at a given signal data rate.Do a quantitative characterization of the signal detection process and definition of the minimal detectable optical power for a particular type of signal distortion with respect to a detection error criterion.Understand optical system components with typical specifications and applications.Optical fibers are used to transmit information over long distances. Fiber-based systems have largely replaced radio transmitter systems for long-haul data transmission. They are widely used for telephony, Internet traffic, long high-speed local area networks (LANs), cable TV (CATV), and increasingly also for shorter distances within buildings.The capacity of fibers for data transmission is huge: a single silica fiber can carry hundreds of thousands of telephone channelsFiber-optic cables are immune to problems that arise with electrical cables, such as ground loops or electromagnetic interference (EMI) Optical Fiber Networks are the future of today and tomorrow because of mind boggling data rate offered, in this first module of course student will become expert in link designLearning Objectives of Module 2 are:Study the troubleshooting instruments:Optical Time Domain Reflectometer (OTDR) andFusion SplicerAnalyze and correct the faults in Fiber Optics Networks using OTDR and Fusion Splicer.Important instruments in optical link maintenance are discussed in this module with online demonstration, so that students will get the practical experience and learn how to use these equipment for network maintenance.
