In optical communication, what is a major advantage of using optical fibers over traditional copper wires?

Using optical fibers in optical communication offers the significant advantage of higher signal strength over longer distances compared to traditional copper wires. This is primarily due to the way optical fibers transmit data. They use light to carry information, which can travel much longer distances without significant loss of signal strength, unlike electrical signals in copper wires that can degrade over longer distances due to resistance and electromagnetic interference.

Optical fibers have lower attenuation rates, meaning they retain the integrity of the transmitted signal over considerable distances without the need for frequent repeaters, making them particularly effective for long-range communications such as in telecommunications and data networks. Additionally, because of their high bandwidth capabilities, optical fibers allow for a greater volume of data to be transmitted simultaneously, further enhancing their effectiveness in communication applications. This is a critical aspect of modern communication infrastructure, enabling faster and more reliable connections.
