Fiber Optics
Fiber optics is a technology that transmits data as pulses of light through thin, flexible glass or plastic fibers, enabling high-speed, long-distance communication with minimal signal loss and electromagnetic interference. It is widely used in telecommunications, internet infrastructure, medical imaging, and industrial sensing applications. The core principle involves total internal reflection within the fiber to guide light efficiently.
Developers should learn fiber optics when working on network infrastructure, telecommunications systems, or IoT devices requiring reliable, high-bandwidth data transmission, such as in data centers, broadband networks, or sensor networks. It is essential for understanding modern internet backbone technologies, 5G networks, and applications in fields like healthcare (e.g., endoscopes) or defense, where secure and fast communication is critical.
