Optical-Fiber
Optical fiber is a technology that transmits data as light pulses through strands of glass or plastic fibers. Each fiber, about the diameter of a human hair, can carry vast amounts of information over long distances with minimal signal loss. Its core is surrounded by a cladding layer that reflects light inward, preventing loss and allowing data to travel efficiently. Optical fibers are crucial in telecommunications, enabling high-speed internet, cable television, and telephone services. They offer advantages like higher bandwidth, faster speeds, and immunity to electromagnetic interference compared to traditional copper cables.
Optical fiber is fundamental to modern communications infrastructure.
