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.
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.
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.

What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
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.
The critical angle in fiber optics is important because it determines whether light can be transmitted through the fiber or not. When light hits the boundary of the fiber at an angle greater than the critical angle, it is reflected back into the fiber, allowing for efficient transmission of signals.
maximam angle through which light can b injected to a optical fiber for its total intenal reflection
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.
yes it is. when a light is incident on one end of fiber at a small angle it is refracted into the 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.

The critical angle is the minimum angle of incidence at which light can strike the boundary between two media and still be refracted; beyond this angle, total internal reflection occurs. This phenomenon is significant in optical applications such as fiber optics, where it allows light to be guided efficiently along the medium without loss. The critical angle depends on the refractive indices of the two media involved, and it illustrates the interplay between refraction and reflection in wave physics. Understanding the critical angle is crucial for designing devices that manipulate light, such as lenses and prisms.
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
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.
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.
Not really. More to do with reflection and the critical angle which gets it to reflect for infinity .
