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.

Objective type question on optical fiber?
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? "
What are the disadvantages of optical fiber?
· Installation/maintenance - It is a quite new technology. Installation and maintenance need knowledge that is not yet available everywhere.· Unidirectional - Propagation of light is unidirectional. If we need bidirectional communication, two fibers are needed.· Cost - More expensive than of other guided media.Physical vibration will show up as signal noise..and difficult to splice.

What is an optical fiber?
#Optical fiber consist of a central core made of class or plastic which is surrounded by a cladding of material of refractive index slightly less than that of core and a protective jacket of insulating material. There are three types of optical fiber configuration.
