Fiber optics is a method of transmitting information using thin, transparent fibers of glass or plastic. The fibers are designed to carry light signals over long distances, making it a popular choice for telecommunication and networking.
Fiber optics work by using the principle of total internal reflection. Light is sent through the fiber, bouncing off the walls of the core and maintaining its intensity as it travels. This allows for the transmission of information without the need for electrical signals.
Fiber optics offer several advantages, including high bandwidth, low signal loss, and immunity to electromagnetic interference. They are also lightweight, flexible, and can transmit data over longer distances compared to traditional copper wires.
Lens physics is the study of the properties and behavior of lenses, which are transparent objects that can refract and focus light. It involves understanding concepts such as refraction, focal length, and magnification, and how they are affected by the shape and material of the lens.
Lenses are used in fiber optics to focus the light signal from the source into a narrow beam before it enters the fiber. This helps to increase the efficiency and range of the transmission. Lenses are also used at the receiving end to expand and collect the light signal for detection and decoding.
