What is the primary function of a fiber optic transmitter?

The primary function of a fiber optic transmitter is to convert electrical signals into optical signals. This process is crucial in fiber optic communication, as it allows the transmission of data over long distances using light instead of electrical currents. The transmitter uses a light source, such as a laser or LED, which takes the electrical data and modulates it to create light pulses that can travel through the fiber optic cable.

This conversion is vital because optical signals are less susceptible to attenuation and electromagnetic interference compared to electrical signals, thus enabling high-speed and long-distance data transmission. By generating these optical signals, the transmitter facilitates the effective communication of information across vast networks, making it a fundamental component of fiber optic systems.
