The laser shines through the fiber optic cable because the edge of the inside of the cable can act as a mirror. This is called internal reflection.
The optical fiber can be used both as unidirectional and bidirectional. The main application of optical fiber is in long-distance links, so there exists no need to employ them as unidirectional. For each direction different wavelengths are used to modulat the signals. At the same time many bidirectional signals can travel through the same optical fiber.
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
The light will be considered energy and that energy bounces side to side through the fiber. There is a constant loss. So the smaller the fiber the less loss you would have.
No. Light is transmitted through optical fibers.

For each direction different wavelengths are used to modulat the signals. At the same time many bidirectional signals can travel through the same optical fiber.
Light waves carry optical fiber signals. These waves are typically in the infrared range and are able to travel long distances through the fiber without losing signal strength.
mode means path, the way in which light travel, in the fiber means angle in multi mode fiber light can travel in more then one angle so it is called multi mode fiber. but in single mode fiber there is dedicated path or single path through which light beam/source can travel.
Light rays pass through the optical fiber by constantly reflecting off the walls of the fiber through a process called total internal reflection. This allows the light to travel long distances without significant loss of intensity.
A light ray propagates through an optical fiber by undergoing total internal reflection at the boundary between the core and cladding of the fiber. This allows the light to travel down the length of the fiber without significant loss in intensity. The core of the fiber has a higher refractive index than the cladding, which is what enables this total internal reflection to occur.
Optical Fiber1. Photon has no mass, and it can travel faster than electron2. In multi-mode fiber, several channels of data can be transmitted at the same time
The main part of an optical fiber is a glass fiber (NOT hollow) within another glass fiber of another type of glass. Both types of glass have a different index of refraction; the signal travels through the inner glass fiber.
Yes, waves can be sent down an optical fiber in the form of light. Optical fibers are specially designed to guide and transmit light waves over long distances with minimal loss. The light waves travel through the core of the optical fiber and are reflected off the walls due to total internal reflection, allowing for efficient transmission.
An optical fiber needs to be engineered with a high refractive index core surrounded by a lower refractive index cladding. This design ensures that light entering the fiber at a shallow angle is continuously reflected off the core-cladding interface through total internal reflection until it reaches the other end of the fiber. This prevents light from escaping and allows it to travel effectively through the fiber.
The concept of light propagation, the transmission of light along an optical fiber, can be described by two theories. According to the first theory, light is described as a simple ray. This theory is the ray theory, or geometrical optics, approach. The advantage of the ray approach is that you get a clearer picture of the propagation of light along a fiber. The ray theory is used to approximate the light acceptance and guiding properties of optical fibers. According to the second theory, light is described as an electromagnetic wave. This theory is the mode theory, or wave representation, approach. The mode theory describes the behavior of light within an optical fiber. The mode theory is useful in describing the optical fiber properties of absorption, attenuation, and dispersion
Optical fibers use total internal reflection to guide light along the fiber. The core of the fiber has a higher refractive index than the cladding, which causes light to continuously reflect off the core-cladding interface as it travels through the fiber. This allows light to travel along a bent path without significant loss of signal.
Electromagnetic radiations in the visible spectrum, such as infrared, visible light, and near-ultraviolet, can be transmitted through an optical fiber. These wavelengths are compatible with the glass or plastic material of the fiber and capable of traveling long distances with minimal loss.
