What do optical splitters do in the forward direction?

• A. Amplify an optical signal
• B. Divide an optical signal across a number of output fibers
• C. Transmit signals without any loss
• D. Convert optical signals to electrical signals

Answer: (B)

Optical splitters serve the primary function of dividing an optical signal into multiple output paths, effectively distributing the signal across various output fibers. This is crucial in fiber optic networks, where a single input signal must be sent to multiple destinations without requiring separate transmitters for each path. The design of optical splitters ensures that they can take an incoming signal and replicate it accordingly, allowing for efficient use of resources in a network. This capability is particularly important in applications like fiber-to-the-home (FTTH) installations, where a single fiber can serve multiple subscribers. In contrast, amplifying an optical signal, transmitting signals without loss, or converting optical signals to electrical signals are not the functions of optical splitters. Amplification would require optical amplifiers, while loss-free transmission is more of an ideal condition than a reality in optics, and converting optical to electrical signals is performed by different types of devices, such as photodetectors.
