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

1. The Angle of Incidence equals the Angle of Reflection. 2. The Angle of Incidence is very SHALLOW. The light travels almost parallel to the sides of the Fiber.
maximam angle through which light can b injected to a optical fiber for its total intenal reflection
Numerical aperture is used to describe the light gathering or light collecting ability of an optical fiber. It is a dimensionless number that defines the cone angle of light that can be accepted by the fiber. A higher numerical aperture indicates a greater ability to collect light.
mode means path, the way in which light travel, in the fiber means angle in multi mode fiber light can travel in more then one angle so it is called multi mode fiber. but in single mode fiber there is dedicated path or single path through which light beam/source can travel.
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? "
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.
