The refractive index difference of multimode optical fiber is

Step-index multimode fibers feature a uniform refractive index within the core and a distinct drop at the core-cladding interface. The refractive index profile is usually rectangular (→ step-index fibers), but sometimes parabolic (see below). When we talk about classification based on. An optical fiber is a cylindrical dielectric waveguide composed of a central core surrounded by cladding with a slightly lower refractive index. This carefully engineered index contrast confines light within the core through total internal reflection, enabling optical signals to travel with. The index of refraction (sometimes referred to as the refractive index or IOR) is an essential characteristic of an optical fiber because it plays a crucial role in determining the fiber's ability to transmit light efficiently, maintain signal quality, and support various applications.
