Fiber optic engineering is the process of designing, installing and maintaining the fiber optic cables that support phone and internet communication. Fiber optic cables are cables made with glass fibers. Those cables transmit information by converting messages into light pulses that travel through. Fiber-optic communication is a form of optical communication for transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. This field is about ensuring information—whether voice, video, or data—can be transmitted efficiently and securely across the globe. It's the backbone of the internet, telephone networks, and more, offering unmatched bandwidth and distance.
