![]() It allows multiple wavelengths of light transmitted in multiple paths at once. Multimode connections have a larger core diameter. Single-mode provides the lowest losses in communication. Single-mode fiber optic, the number of light reflections in the core is less resulting in low attenuation and allowing data to travel further, faster. Optical fiber cable comes in single-mode or multimode connections. The potential hazard of Infrared red light used in telecommunications cannot be seen by the naked eye. Optical fiber cable uses light pulses instead of electrical pulses to transmit data. Optical fiber transfers data at the speed of light in the glass. Plastic fiber is used for short communication. There are two types of optical fibers, glass, and plastic. ![]() Which is an outer layer for protecting the cable from damages. Whose refractive index is less than the core? The purpose of cladding is to keep the light reflections in core instead of being reflections. Which surrounds the core, with refractive index n2. The core will have a higher refractive index than cladding. It is the inner layer is called the core, with refractive index n1. It also is known as fiber optic cable consists of strands of one or more fibers inside the casing and its assembly is similar to electrical cable.
