In what form does the signal flow in fiber optical communication?
In fiber optic communication, the signal flows in the form of light waves. Optical fibers transmit data using pulses of light that travel along the fiber’s core, which is typically made of glass or plastic. These light waves carry digital information over long distances with minimal loss and high bandwidth.

Fiber optic communication transmits signals in the form of light waves. The correct answer is [A] Light wave. Optical fibers, made of glass or plastic, carry data using pulses of light that travel along their cores. These light waves represent digital information encoded as on-off pulses, allowing for high-speed and efficient transmission over long distances. Option B, radio waves, and option C, microwave waves, are used in wireless communication systems, not in fiber optics. Option D, electric waves, typically refers to electrical signals conducted through wires, which are not used for long-distance data transmission in fiber optics. Fiber optic communication’s reliance on light waves ensures minimal signal loss and interference, making it suitable for high-performance telecommunications and internet connectivity. Therefore, the signal flow in fiber optic communication is primarily in the form of light waves (option A).
