What are the basic components of a fiber optic system?

The basic components of a fiber optic system are indeed the transmitter, fiber optic cable, and receiver.

The transmitter is responsible for converting electrical signals into light signals, which allows data to be transmitted over the fiber optic cable. This conversion is essential for fiber optics, as they rely on light to carry information through the fiber strands, which are made of glass or plastic.

The fiber optic cable serves as the medium that carries the light signals from the transmitter to the receiver. Its design minimizes loss of signal strength and provides a high bandwidth, allowing for rapid data transmission over long distances without significant degradation.

Finally, the receiver performs the reverse function of the transmitter, converting the light signals back into electrical signals for interpretation by various devices. This completes the communication cycle within the fiber optic system, ensuring that data can be sent and received effectively.

The other options contain components that, while important in other contexts, do not represent the fundamental elements of a fiber optic system. For instance, amplifiers, routers, and cable modems typically pertain to different types of communication systems or network configurations rather than the specific workings of fiber optic technology.
