Selecting a network cabling installer

当您需要在业务中安装新的结构化电缆时，是时候选择正确的安装程序了. 但是您应该对您的设计和安装团队有什么期望呢?

Every cabling design and installation project is different. 但是，无论是一个校园范围内的项目，需要骨干电缆和水平电缆，还是一个更简单的单一建筑项目，安装团队的某些特征和行动可以提示你，供应商是否能满足你的需求:

They provide consultation and recommendations

我们建议寻找适合您未来计划的正规网赌十大排行. 好的基础设施提供商会与您会面，讨论您当前和未来的需求, as well as to survey your current plans and infrastructure. They'll also consult with other key professionals.

Find an installer with an eye to your future

A structured-cable solution is your network's foundation, and the provider's job is to focus on that foundation's value. 只安装你现在需要的可能满足今天的需求，但长远规划才是更明智的, more economical solution. 一个好的基础架构提供商会希望您的正规网赌十大排行既能作为业务健康运行的基础，又能工作10到15年.

Experience to succeed

Network installations are as much an art as they are a science. And “book learning” is no a substitute for experience. 选择一个有必要的经验，使您的项目成功的安装程序.

A picture is worth a thousand words

你可以从安装人员的照片集中看出他们的工作质量、组织结构以及他们对细节的关注. 所有这些都是成功安装的重要特征. 花点时间仔细阅读安装程序组合中的照片，以判断他们是否适合您.

Power over Ethernet comparison

POE vs POE+ vs 4PPOE (802.3af vs 802.3at vs 802.3bt)

POE – the beginning

以太网供电(PoE)与传统供电方式相比具有许多优点, including time and cost savings, flexibility, safety, reliability, and scalability. POE也是一种低压电源，在大多数地方不需要遵守高压电气法规.

主要缺点是可用电力有限. Initially, 802.3af -由电气和电子工程师协会(IEEE)采用的第一个POE标准提供了15.4W的功率，对于当时的IP电话和其他简单应用来说已经足够了. 但随着更复杂的应用进入市场，对更大功率的需求也越来越大.

POE Plus and Internet of Things (IoT)

Then in 2009, the (IEEE) released IEEE 802.3at also known as POE Plus (or POE+). POE Plus指定POE源功率为30W，设备功率为24W. POE Plus为蓬勃发展的IoT(物联网)市场提供了更多的灵活性. 物联网(IoT)指的是大量涌入的新设备，这些设备需要电力和网络连接，有助于连接我们日常生活的方方面面.

各种各样需要电力和数据的设备正在进入市场，这是最初的POE标准所没有预料到的. This includes things like smart thermostats, smart doorbells, IP cameras, IP based alarm systems, Internet controlled lighting, and Wi-Fi access points. POE Plus可以同时为这些设备提供电源和数据连接.

What is 802.3bt – 4PPOE?

Power Capacity of the 3 POE Standards

为了满足对更大功率的需求，IEEE引入了IEEE 802.3bt in 2018. IEEE is also referred to as 4PPOE or “BT”. 802.3bt expands the maximum PoE power available, 将电源设备(PSE)的功率限制提高到90W，动力设备(pd)的功率限制提高到71 w.3W. 这个新标准通过利用所有四对结构化布线实现了这一点. Additionally, IEEE 802.3bt supports multiple PoE classes and is backward compatible.

The 802.3bt标准很可能是一段时间内最高功率的POE标准. 该标准不仅面临着工程上的挑战(它已经使用了所有四对电线来传输电力), 它还面临着监管问题，因为90W非常接近允许通过电线发送的最大功率，而不必遵守高压布线所需的标准和法规.

802.同时，3bt也满足了某些大功率设备的需求. 其中包括电动PTZ (Pan Tilt Zoom)十大网赌正规网址和高功率Wi-Fi接入点. 802.3bt还可以为手机、平板电脑甚至笔记本电脑充电.
