• How it works:
  • Optical fibers transmit data as pulses of light.
  • A laser or LED at the source converts electrical signals into light pulses.
  • These light pulses travel through thin strands of glass or plastic within the fiber optic cable.
  • At the destination, a photodetector converts the light pulses back into electrical signals.
  • Because light travels very quickly, and optical signals experience minimal loss over long distances, fiber optic networks offer significantly faster and more reliable internet connections compared to traditional copper-based networks.

2. Medical Endoscopy:

• How it’s used:
  • Optical fibers are essential components of endoscopes, which are used to visualize internal organs and tissues during medical procedures.
  • Endoscopes are inserted into the body through small incisions or natural openings.
• How it works:
  • Optical fibers transmit light to illuminate the internal area being examined.
  • Other fibers within the endoscope capture images of the internal structures and transmit them back to a display screen.
  • This allows doctors to visualize internal organs and perform minimally invasive procedures with greater precision.
  • The thin and flexible nature of optical fibers allows for the creation of very small and maneuverable endoscopes.

Summary:

Optical fiber technology has become indispensable in modern society. Its ability to transmit large amounts of data quickly and reliably has transformed internet and broadband services, enabling faster communication and access to information. In the medical field, optical fibers have revolutionized diagnostic and surgical procedures, allowing for minimally invasive techniques and improved patient outcomes. The use of light to transmit information, coupled with the physical properties of the optical fibers themselves, is what allows these technologies to function.
