Welcome!
The copper-clad steel telephone wire is relatively hard and is not suitable for external cable pulling, which is easy to break the core. But it can still be used if buried in the wall. It can only be used in close range. The telephone line made of imported polypropylene material has high purity, lower transmission attenuation and higher transmission speed. It is suitable for broadband internet access and can meet the requirements of high transmission speed of videophone.
