我又去看了下Merging的文档,和推荐的switch
https://confluence.merging.com/display/PUBLICDOC/Network+Switches+for+RAVENNA+-+AES67
这个大部分不推荐的switch被刷掉的原因都是PoE功率不够。
Power over Ethernet (PoE)
Power over Ethernet (PoE) is a technology for wired Ethernet local area networks (LANs) that allows the electrical current necessary for the operation of each device to be carried by the data cables rather than by power cords. Doing so minimizes the number of wires that must be strung in order to install the network. PoE was originally developed in 2003 to support devices like Wi-Fi access points (APs). PoE made AP installations easier and more flexible, especially on ceilings.
数据网线上面跑电流驱动设备这个完全不hifi啊 我们一边说一点点接地噪音,屏蔽层带来的区别可能是可闻的千差万别。专业领域已经开始PoE了。 哎,该说点什么好呢
