Telephone cables connect circuits in a system. For example, they join landline telephones or PCs to telecommunications networks. They play a vital role in our interconnected world, transmitting both sound and data from location to location.
Telephone cable makes use of electrically conductive materials such as copper wiring to transmit data electromagnetically. The outer insulation is typically PVC (polyvinyl chloride) or polyethylene (PE). They are low-frequency devices, meaning that they operate below 300 kilohertz.
This guide offers a comprehensive introduction to telephone cables. Learn how they work, what they are used for and the different types available.
