Yes true
Yes, that is true - and that is commonly used in modern technology, but especially to transmit information. Note that in an optic fiber, light travelling along the fiber is simply reflected back inside, if it reaches the borders.
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
Light goes under total internal reflection.
An optical fiber is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers.
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.
An optical fiber (or fibre) is a glass or plastic fiber that carries light along its length. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications

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
Yes true

Some of the light injected by the optical transmitter is lost along the length of the fiber as the light travels. The optical receiver needs a minimum amount of light to function properly. Therefore optical repeaters must be installed at intervals along the path to keep the light level above the level needed by the last receiver.
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.
