Fiber-optic technology uses thin strands of glass or plastic, known as fiber-optic cables, to transmit data as light signals. This method allows for high-speed communication over long distances, making it ideal for internet connections, television, and telephone services. The light travels through the fibers, bouncing off the walls, which minimizes loss and interference. One of the main advantages of fiber-optic systems is their ability to carry large amounts of data at once, far surpassing traditional copper cables. This results in faster internet speeds and more reliable connections, benefiting both homes and businesses in our increasingly digital world.
