How do telecommunication cables ensure signal integrity over long distances?

Telecommunication cables are constructed from materials chosen specifically for their ability to carry signals with minimal loss or interference. Copper, the traditional material for electrical signal transmission, has low resistance and is highly conductive, allowing signals to travel effectively over short to medium distances. However, for long-distance applications, fiber optic cables are increasingly preferred. Fiber optic cables transmit data as light pulses through glass or plastic fibers, which are not susceptible to electrical interference. This material offers incredibly low attenuation, allowing signals to travel thousands of kilometers with minimal degradation. The low resistance and high transmission capacity of these materials are critical for maintaining signal strength over long distances.
