WebGiven speed of light in vacuum, it would take 14.1 nanoseconds for the photon to travel the reflected path, whereas it would take 10.0 nanoseconds to travel 3 meters linearly. Both the distance & duration are about 40% increases! Since L = 3 m and t = 14.1 ⋅ 10 − 9 s, then the "linear" photon speed in the fibre optic cable is v γ, f o = 2. ... WebOptical Fiber is a flexible and transparent fiber made of drawing glass that is silica or plastic to a diameter slightly more than a human hair (including the outer coating). It helps in transmitting the data in the light form and thus the transmission is much quicker compared to the electrical wires.

"WebAn optical fiber consists of three concentric elements, the core, the cladding and the outer coating, often called the buffer. The core is usually made of glass or plastic. The core is the light-carrying portion of the fiber. The cladding surrounds the core. The cladding is made of a material with a slightly lower index of refraction than the core.
