Telephone & Switchboard

communication is the basic necessity of everyday living. With the advent of our technology in telephone data cables, the communication thus becomes easier. Telephone pair cables are made of high-quality conductive copper wires. The insulated cores of these cables are twisted to form a pair which is further connected with telephone switching line to offer noise-free audio signal. The structure of these cables makes them easy to connect, protecting from interference and capable of rectifying noise while offering a clear audio signal.
