Will cat copper cable be replaced by optical fiber?

May 07, 2020

Copper cable will still be an integral part of the data center, and in the application of voice transmission, power supply and other special environments, in addition to voice signal transmission and wireless access, POE power supply system and other applications, optical fiber can not replace copper cable.


First, because copper cable is different from optical fiber in data transmission through electric pulse, which can support voice signal, so copper cable can be applied to voice transmission, but optical fiber can not.

Second, the glass fiber used in the optical fiber can not conduct electricity, while the copper in the copper cable can conduct electricity.

So traditional Cat5e Cat6 and Cat7 will still have the space even in the future.
