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.
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
optical fibre milatary applications
Good optical fiber is made of glass, but inexpensive fiber is sometimes made of plastic.

Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
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.
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? "
· 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.

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.
Yes, they are the exact same thing
what is fiber optics what is fiber optics
#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.
