Which components are essential in an optical communication system?

In an optical communication system, the essential components are a transmitter, optical fiber, and receiver. The transmitter converts electrical signals into optical signals, typically using a laser or LED to emit light into the optical fiber. The optical fiber then serves as the medium that guides these light signals over distances while maintaining signal integrity and minimizing losses due to scattering and absorption. Finally, the receiver detects the incoming optical signals and converts them back into electrical signals for further processing or utilization.

This structure is fundamental to how optical communication works, as each component plays a crucial role in ensuring that data is transmitted efficiently and accurately from the source to the destination. The other options include components like antennas, generators, or cameras, which are more relevant to other types of communication systems and do not capture the core elements specific to optical communication.
