Telecommunications (fiber optics)

Fiber optics is a technology that uses thin strands of glass or plastic to transmit data as pulses of light. These light signals carry information over long distances at very high speeds, with minimal loss and interference. Unlike traditional copper wires, fiber optic cables are less affected by electrical noise and can support greater bandwidth, making them ideal for internet, phone, and television connections. The light signals are generated by lasers or LEDs and travel through the fibers via internal reflection, enabling fast and reliable communication. This technology underpins much of our modern digital infrastructure.
