Fiber optic cable has steps

Fiber optic cables involve both specific installation steps and types, including step-index fibers that guide light through a uniform core. Types of Fiber Optic CablesStep-index fibers are a type of optical fiber where the core has a uniform refractive index, surrounded by cladding with a lower refractive index. Light travels in a straight path through the core, making them suitable for short-distance communication due to higher modal dispersion.

In contrast, graded-index fibers gradually reduce the refractive index from the center outward, which helps reduce signal distortion over longer distances. Fibers can also be classified by mode of propagation: single-mode fibers for long distances with a small core (
