- 2. How Fiber Optics Work Fiber-optic lines are strands of optically pure glass as thin as a human hair that carry digital information over long distances. They are also used in medical imaging and mechanical engineering inspection.
- 3. How Fiber Optics Work (2) How Does an Optical Fiber Transmit Light? The light in a fiber-optic cable travels through the core (hallway) by constantly bouncing from the cladding (mirror-lined walls), a principle called total internal reflection. Because the cladding does not absorb any light from the core, the light wave can travel great distances.
- 4. Fiber-Optic Relay System The optical receiver is like the sailor on the deck of the receiving ship. It takes the incoming digital light signals, decodes them and sends the electrical signal to the other user's computer, TV or telephone (receiving ship's captain). The receiver uses a photocell or photodiode to detect the light.
- 5. How Are Optical Fibers Made? Optical fibers are made of extremely pure optical glass. glass window as transparent, but the thicker the glass gets, the less transparent it becomes due to impurities in the glass. If you were on top of an ocean that is miles of solid core optical fiber glass, you could see the bottom clearly.
