Is fiber optic communication based on electromagnetic wave propagation
Optical communications, often referred to as fiber optic communications, relies on the transmission of information in the form of electromagnetic waves, particularly in the optical spectrum. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred. Plastic optical fibers, while generally more flexible and easier to handle, serve well in short-distance communications, providing adequate signal quality. The structural integrity and materials of fiber optics contribute to their resilience against environmental factors, making them suitable for. The light signals propagate to the receiver through the fiber optic cable. By optimizing parameters like wavelength, transmission speed, capacity, efficiency, and distance can be maximized. Is fiber. ormation from one place to another by sending pulses of light through an optical fiber.
