Which part of the fiber optic system is responsible for sending the light signal?

• A. Receiver
• B. Transmitter
• C. Amplifier
• D. Connector

Answer: (B)

The transmitter in a fiber optic system plays a crucial role in sending the light signal. It converts electrical signals into light signals that can travel through the optical fiber. The transmitter typically consists of a light source, which might be a laser or light-emitting diode (LED), and circuits to modulate the light according to the data being transmitted. This modulation is essential because it encodes the information into the light signal that travels through the fiber optic cable. The transmitter is located at the beginning of the fiber optic link and is responsible for initiating the signal transmission. This makes it vital for communication systems that rely on fiber optics for high-speed data transmission. Understanding the function of the transmitter is fundamental for anyone involved in working with fiber optic technologies, as it directly impacts the system's performance and efficiency.
