为什么华为通信电源要用48V电源?

      通常不是网络通信技术人员，大概没有听过通信电源这个东西，但是就是这个不起眼的通信设备，关系到我们日常用的网络是否通畅。对我们的生活起到了至关重要的作用。平时，我们通信系统中，用到的通信电源，通常用的是48V的电源。为什么通信电源要用48V电源？

      其实，这跟历史有一定的关系。最初我们的通信系统只包括电话，那个时候还是座机，而座机的通信网络不是很复杂，考虑到安全因素，早期使用的都是48V，后来为了兼容原本的电话网络就一直延续了下来，没有更改。

      此外，也是为了确保人体的安全。我们人体的安全电压限制我们人体可通过的电流不能超过9毫安。48V产生的电流是0.96毫安，这对我们人体的生命安全不会有威胁，所以，通信电源基本维持48V电源。

Why does the communication power supply use 48V power supply?

Usually it's not a network communication technician. I haven't heard about the communication power supply, but it's the humble communication equipment that concerns the smoothness of our daily network. It plays a vital role in our life. At ordinary times, the communication power used in our communication system is usually 48V. Why does the communication power supply use 48V power supply?

In fact, it has something to do with history. At first, our communication system only included telephone. At that time, it was still a landline, but the communication network of landline was not very complex. Considering the security factors, the early use of 48V, and later in order to be compatible with the original telephone network, it has been continued without change.

In addition, it is also to ensure the safety of human body. The safe voltage of our body limits the current that our body can pass through to no more than 9 ma. The current generated by 48V is 0.96ma, which will not threaten our life safety. Therefore, the communication power supply basically maintains 48V power supply.
