课程名称：结构布线系统基础 课程概述：在这个培训课程中，学员将学习结构布线系统的基础知识。结构布线是一个建筑或校园的布线基础设施，包含多个标准化的较小元素（称为子系统）。结构布线组件包括双绞线和光纤布线、配线架和跳线。该课程将介绍如何设计和安装能满足当前及未来需求的布线系统，使未来添加的硬件能够得到支持。 课程内容涵盖布线设计和安装的标准，主要涉及数据中心、办公室和公寓建筑的数据或语音通信布线，常用的电缆类型包括5类增强（Cat 5e）、6类（Cat 6）和光纤布线及模块化连接器。这些标准定义了如何在不同拓扑结构中铺设电缆，以满足客户需求，通常使用中心配线架（通常为19英寸机架安装），从中可以根据需要进行每个模块连接。每个出口连接到网络交换机（也通常是机架安装）或IP电话系统的配线架。 布线标准要求Cat 5e/6/6A电缆的所有八根导线都必须连接。IP电话系统可以在相同的电线上同时运行电话和计算机，消除单独电话布线的需要。无论铜缆类型（Cat 5e/6/6A）如何，永久链接安装的最大距离为90米，另外加上10米的跳线。 Cat 5e和Cat 6都能有效支持最大90米的以太网供电（PoE）应用。然而，由于Cat 5e电缆的功率损耗较大，使用Cat 6A电缆连接和供电PoE设备时，性能和电力效率更高。 该课程帮助学员全面了解结构布线系统的设计与实施，为实现高效、可靠的通讯基础设施打下基础。
On this training you will learn the basics of a Structured cabling system, is building or campus cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called subsystems. Structured cabling components include twisted pair and optical cabling, patch panels and patch cables.Structured cabling is the design and installation of a cabling system that will support multiple hardware uses and be suitable for today's needs and those of the future. With a correctly installed system, current and future requirements can be met, and hardware that is added in the future will be supported.Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications using various kinds of cable, most commonly category 5e (Cat 5e), category 6 (Cat 6), and fiber optic cabling and modular connectors. These standards define how to lay the cabling in various topologies in order to meet the needs of the customer, typically using a central patch panel (which is normally 19-inch rack-mounted), from where each modular connection can be used as needed. Each outlet is then patched into a network switch (normally also rack-mounted) for network use or into an IP or PBX (private branch exchange) telephone system patch panel.Cabling standards require that all eight conductors in Cat 5e/6/6A cable be connected.IP phone systems can run the telephone and the computer on the same wires, eliminating the need for separate phone wiring.Regardless of copper cable type (Cat 5e/6/6A), the maximum distance is 90 m for the permanent link installation, plus an allowance for a combined 10 m of patch cords at the ends.Cat 5e and Cat 6 can both effectively run power over Ethernet (PoE) applications up to 90 m. However, due to greater power dissipation in Cat 5e cable, performance and power efficiency are higher when Cat 6A cabling is used to power and connect to PoE devices
