Overview of How Fiber Optic Networks Function
Fiber optic networks operate by transmitting data in the form of light pulses through optical fibers made of glass or plastic. These fibers are designed to carry light signals over long distances with minimal loss of signal strength. The core of the fiber acts as a pathway for the light to travel, surrounded by a cladding layer that reflects the light back into the core, ensuring that it stays within the fiber. At the ends of the fiber, transmitters convert electrical signals into light pulses, which travel through the fiber and are then converted back into electrical signals at the receiving end. This process enables data to be transmitted quickly and efficiently across vast distances.
