Lecture 4
In order to accurately study optical modes, the complete Maxwell equations are to be solved. Anyway, for multimode fibers, the following intuitive explanation can be given: Each mode corresponds to a

The FOA Reference For Fiber Optics
Using Snell''s Law, we can calculate the angle at which an optical fiber begins total internal reflection, which happens like this drawing below, when the refracted ray lays along the boundary between the

The total internal reflection criterion imposes a limit on the radius of curvature of fiber optic cable. If fiber optic cable is bent such that the radius of curvature is too small, the critical angle will be exceeded at

Acceptance angle: It is the maximum limit for the angle of incidence of the incident ray such that the ray refracted in to the core grazes the interface as it falls on the core-cladding interface.

Optical fibres are not affected by radio frequency interferences (RFI) and electromagnetic interferences (EMI).
Diffraction-limited system
In optics, any optical instrument or system – a microscope, telescope, or camera – has a principal limit to its resolution due to the physics of diffraction. An optical instrument is said to be diffraction-limited
