USB-IF设定最大线缆长度以维持性能

USB Implementers Forum (USB-IF) 已经为USB线缆设定了最大推荐长度,以确保最佳性能。这些长度因USB代际而异,像USB 1.0和2.0等较旧的标准允许长达16.4英尺,而USB 3.0至3.2等较新的标准则限制在9.8英尺。USB 4线缆的推荐长度最短,为2.6英尺,无论它们使用USB-A还是USB-C接口。超出这些限制可能由于信号衰减和更容易损坏而导致数据传输速度变慢以及为连接设备提供的电力减少。 AI

    USB线缆多长算太长?

    USB cables, much like their HDMI cousins, have limits on how long they can be. The thing is, those limits are probably much lower than you expected.
