Home / What does optical fiber channel mean
A fiber-optic link (or fiber channel) is usually a part of an optical fiber communications system which provides a data connection between two points (point-to-point connection). Fibre Channel is primarily used to connect computer data storage to serversin storage area networks (SAN) in commercial data centers. In contrast to wire transmission, in which an electric current flows through a copper conductor, in optical fibre transmission an electromagnetic (optical) field propagates through a fibre made of a nonconducting dielectric. An optical fiber can be understood as a dielectric waveguide, which operates at optical frequencies.
