Radio over fiber is the act of the communication system in the adoption and application of the analogue fiber optic links to enhance the transmission and distribution of the radio signals from the relevant central location (situation of the base) to numerous remote locations with the essence of the antennas in those areas (Wake p. 2). Radio over Fiber is the essence of analog transmission in relation to the fiber technology in the presence of light amplitude modulation under the influence of the radio signal. This is transmitted over the optic fiber link with the aim of initiating or promoting wireless access or transmission of information. Despite the aspect that radio transmission in relation to numerous purposes, the term RoF is usually coined in the application of radio transmission in the context of wireless access or networking. This is one of the most emerging technologies in relation to the transmission of data because of its ability to transmit large amount of data.
The optical fiber is a very small waveguide. In an environment free from stress or external forces, this waveguide will transmit the light launched into it with minimal loss, or attenuation.
Using DWDM, up to 80 (and theoretically more) separate wavelengths or channels of data can be multiplexed into a light stream transmitted on a single optical fiber.
Fiber optic communications is dependent on the principle that light in a glass medium can carry more information over longer distances than electrical signals can carry in a copper or coaxial medium....
Doubly Clad Fiber
Optical fiber that exhibits wide transmission bandwidth and low bending loss to reduction of guided modes as a result of the high-refractive index external cladding and the tight confinement within the core regions.
A system for fabricating optical fiber, consisting of a furnace that heats the materials, a polymer coating stage, a capstan-pulling apparatus that free-draws the preform into a fiber and a drum on which the finished product is wound.
A cable that delivers service to an individual customer.
In cables, one that contains two fibers.
Light ARMOR Cable
