Have you ever wondered how the internet moves at such lightning speeds

Optical fiber cables carry data using pulses of light, traveling at approximately the speed of light. These pulses travel down super thin strands of glass, much thinner than a human hair.

The glass fibers act as waveguides, keeping the light confined and bouncing it along the cable’s length. This method of transmission, known as total internal reflection, allows for extremely fast and efficient data transfer. Without optical fibers, our world of high-speed internet, video streaming, and instant communication would be much slower and less interconnected.

Prompt:
Imagine a world where data travels at the speed of light.

What groundbreaking technology utilizes the incredible speed of light to transmit information?
