A section of a tangent vector bundle is a vector field. In the mathematical field of topology, a section (or cross section) of a fiber bundle is a continuous right inverse of the function. In other words, if is a fiber bundle over a base space, : then a section of that fiber bundle is a continuous map, such that.
An optical fiber (or optical fibre) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.iber supporting only one mode is called single-mode or mono-mode fiber. The behavior of larger-core multi-mode fiber can also be modeled using the wave equation, which shows that such fiber supports more than one mode of propagation (hence the name).
