How Fiber Optics Work

The working principle of Optical Fiber is to transmit information in the form of light waves or photons (Photons). Unlike cables made of copper that transmit data using electricity, Fiber or Fiber Optics uses light signals that have been converted from electricity to transmit data.

Optical fibers transmit data in the form of light particles or photons in the form of digital pulses via optical fiber cable. Cores and cladding in optical fibers each have a different refractive index that deflects incoming light at certain angles. When light signals are sent through fiber optic cables, they bounce Core and Cladding in a series of zig-zag bounces, following a process called Total Internal Reflection.

Please note that the light signal on optical fiber can not move according to the speed of light, this is because the glass layer on the optical fiber is denser. The light signal in this optical fiber can only move about 30% slower than the speed of light. To update and enhance the signal along the way, optical fiber transmissions sometimes require repeaters at certain distance intervals. This repeater is used to convert optical signals in the form of light into electrical signals and then process the electrical signals and transmit them back to optical signals.

Strengths and Weaknesses of Optical Fiber Cables
Fiber Optic Cable has many advantages and has been widely used for high-speed data transmission. But this optical fiber cable also has weaknesses. The following are some of the advantages and disadvantages of fiber optic cables.
