Step 1: Understanding the Concept:
Optical fiber technology uses thin strands of glass or plastic to transmit data over long distances. Unlike traditional copper wires that use electrons, optical fibers utilize photons to carry information.
Step 2: Key Formula or Approach:
The core principle of optical fiber communication is Total Internal Reflection (TIR), which allows electromagnetic waves in the visible or infrared spectrum to travel through the fiber with minimal loss.
Step 3: Detailed Explanation:
In an optical fiber system, an electrical signal (data) is converted into light pulses by a light source, such as a Laser or an LED. These light pulses travel through the fiber core. At the receiving end, a photodetector converts these light pulses back into electrical signals. Because light has a much higher frequency than electricity, it can carry significantly more data.
Step 4: Final Answer:
The signal is transmitted in the form of light pulses.
