Copper-based communications systems

“

- [Instructor] Just like the telegraph, modern communication systems are based on their use of copper conductors using pulses of electricity to transmit information. Copper cables are installed and connected to end user equipment, such as telephones, computers, copy machines and printers, cameras, speakers, and a whole bunch of other user equipment. Cables must be installed by qualified individuals with a good understanding of how the systems work and who know how to avoid interruptions due to poor craftsmanship. Copper is used in cables because of its low resistance to electricity and its ability to carry signals great distances with little disturbance. Here's how it works first, electricity, direct current specifically, is modulated on copper wires to make a frequency. This frequency can be turned back into sounds by the use of a magnetic speaker, like that found in a telephone handset. Usually, a pair of copper wires makes up this pathway between the two users. Small diameter…
