How data is transmitted through fiber optic cables

1. Light signals: Data is transmitted through fiber optic cables in the form of light signals. These signals are generated by lasers or light-emitting diodes (LEDs) at one end of the cable and converted back into electrical signals at the receiving end.

2. Total Internal Reflection: When light signals travel through the core of the fiber optic cable, they undergo total internal reflection, bouncing off the walls of the core due to the difference in refractive index between the core and cladding layers. This mechanism ensures that the light signals do not dissipate as they travel through the cable.

3. High Bandwidth: One of the key advantages of fiber optic networks is their high bandwidth capacity, allowing for the transmission of large amounts of data at incredibly fast speeds. This makes fiber optic networks ideal for applications that require real-time data transmission, such as video streaming and cloud computing.
