Explanation
to RG series connecting coaxial cable products:
RG series connecting net coaxial cable is
mainly used in the mixed system (HFC net ) of optical cable and coaxial
cable, connecting optical cable to users, used in the telecommunication
business, such as passing data, signals of TV, telephone and computer
in wide-beit holding multi-functional public net. Its advantages:
⑴Wide range of using frequency;
⑵Better anti-interference, fit for double-direction transmission;
⑶Multi-function can more satisfy the needs of the development of future
information industry.
