Telephone communication system consists of a single user circuit; a physical wire connecting the device to the telephone communication network. The wires can be made in copper and typically have a twisted pair configuration. These configurations avoid possibilities of electromagnetic interferences from external sources and, together with a shielding layer, ensure a better performance.
The Telephne cables are often used for indoor telephone applications grouped into sets of 25 pairs, whilst outdoor cables are composed by hundreds of pairs. As most of cables, telephone cables must withstand environmental disadvantaged conditions such as dust, humidity, extreme temperature and be flame retardant and halogen free. Copper wire quality, as well as foaming extrusion, are part of the efficiency of signal.
We at SAMP always aim for the top, and this is the reason why we are certified ISO 9001 and ISO 14001: an acknowledgement of our commitment to the environment and of our ability for design, development and manufacturing process as well. Our solid and strong expertise in copper related technology and our full understanding of industry needs - including high transmission speeds and no interferences - ensure our ability to design and manufacture the best solution you can find on the market from the drawing to the extrusion (e.g. insulation & drawing in one line only), passing through the wire assembling (bunching) and final cable sheathing with cable marking.
