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
how to design optical fiber link???????? . which coditions we have to keep in our mind in designing fiber network?????.in designing purpose which types of sours we will use & why???????????????????????
It can be either or depending on the circuit, here's a link that will help you more: http://communication.howstuffworks.com/fiber-optic-communications/fiber-optic.htm
40 GHz
Usually, there is a laser diode that is optically coupled to the fiber.
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
An objective type of question on optical fiber is on that focuses on the integral part of fiber optic. A good question would be, " Why are optical fibers immune to EMI? "
Describe refraction and reflection with respect to Fiber Optical Cable?
no, its cylindrical
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.
An Optical Link Budget is the overall gains and losses within an optical network. Having this budget would than allow for the cost effective selection of transmitter, receiver (transceiver) at each end of a network.
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.
