How Data Is Transmitted Over Fiber Optics Using Light Pulses

Ever wonder how data transmits over fiber optic cables?

Fiber optic cables use light signals to transmit data at incredibly high speeds. The data is converted into light pulses that travel through the core of the cable, bouncing off the walls due to total internal reflection. This allows for data to travel long distances with minimal loss of signal strength. To allow lots of data to travel over the same fiber optic cable, different wavelengths of light are used. This is called wavelength division multiplexing (WDM), where multiple signals are sent simultaneously at different wavelengths of light. This allows for a large amount of data to be transmitted over the same cable without interference.
