Fiber optics is a technology that sends data as pulses of light through strands of glass. This method allows high-speed data transmission over long distances with minimal loss, making it essential for modern data networks, telecommunications, and the internet. The light is a form of carrier wave that is modulated to carry information. These cables carry digital information as light pulses and thus provide data transfer at much higher speeds than traditional copper cables. These fibers minimize signal loss over extended distances, making them ideal for national broadband, metro, and long-haul networks that require.
