as we know that we apply light ray as source instead of electricity in case of OFC (optical fiber cable) communication but not all ray will propagate so that only those rays that have an angle greater than the critical angle can be transmitted and that reference angle is called ACCEPTANCE ANGLE.

What is the significance of normalized frequency in optical fiber?
If V is less than 2.405 then the fiber is mono mode but if V is greater than 2.405 then fiber is multimode. V number is also related with the number of modes is the fiber as: N = V2/ 2 for step index fiber and Number of modes for graded index fiber is N = V2/ 4.
What are fiber optic termination boxes?
Fiber optic terminal box generally refer to the box shape fiber optic management products used to protect and distribute the optical fiber links in FTTH Networks. Usually the fiber optic box includes the fiber optical patch panels and fiber optic terminal box. Fiber optic patch panel is bigger size, fiber optic termination box is smaller. Actually there are too many fiber optic boxes and fiber management devices, they are hard to count the types, many manufacturers will make the fiber optic boxes according to their own design and they may give the fiber optic boxes different names and model numbers.
Explain about optical fiber types modes and configurations?
fiber cable dia meeter
What is the significance of negative values of voltage and current?
What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
What is dark fibers?
In fiber optic communcations Dark Fiber or Unlit Fibers refers Unused fibers, available for use
Is acceptance angle a performance factor for fiber optic cable?
Yes, because if you exceed the critical angle you will be out of the acceptance angle and the light will not reflect properly and the resulting signal will not be usable.
Definition of acceptance angle of fibre?
maximam angle through which light can b injected to a optical fiber for its total intenal reflection
What can you ay about the angle of incidence when a ray of light travels along and optical fiber?
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.
Is optic fiber an application of refraction?
yes it is. when a light is incident on one end of fiber at a small angle it is refracted into the fiber.
What is mode in optical fiber?
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.
What is significance of pressure angle in gears?
because potato. -kirby A.
What effect would a greater acceptance angle have on minimum resolvable distance in microscopy?
When talking about numerical aperture it is mainly used in microscopy, which helps describe the acceptance area angle of an objective. The numerical aperture can found using this formula NA=nx
What is the significance of normalized frequency in optical fiber?
If V is less than 2.405 then the fiber is mono mode but if V is greater than 2.405 then fiber is multimode. V number is also related with the number of modes is the fiber as: N = V2/ 2 for step index fiber and Number of modes for graded index fiber is N = V2/ 4.
What is used to describe the light gathering or light collecting ability of an optical fiber?
a. Critical angle
How does light travel through a fiber optic?
light enters the fiber optic wire at what is known as a critical angle. As the light bounces off the inside of the wire it does so at or above the critical angle and thus it cannot escape the fiber optic wire. the reason for this phenomena is because the medium of the wire is more dense then that of the medium outside the wire.
What is significance of solid angle?
The solid angles help us have a view of an object in three dimensions.
Is fiber optic cable related to refraction?
Not really. More to do with reflection and the critical angle which gets it to reflect for infinity .
