How does a fused biconical taper (FBT) splitter function?

• A. By amplifying the optical signal
• B. By dividing optical signals into multiple outputs
• C. By combining multiple input signals
• D. By redirecting the optical path

Answer: (B)

A fused biconical taper (FBT) splitter is specifically designed to divide an incoming optical signal into multiple output fibers. The FBT splitter uses a technique where two or more optical fibers are fused together in a controlled manner while being drawn down to a taper. This process allows for the redistribution of light energy within the fibers. When light enters the splitter through one fiber, it is coupled into the fused region and then split into two or more output fibers. The ratio of how the light is split can be tailored during the manufacturing process, allowing for different splitting ratios depending on the application requirements. This ability to share the optical signal makes FBT splitters particularly useful in various optical networking applications, such as passive optical networks (PONs) and local area networks (LANs). Understanding the primary function of FBT splitters—that they serve to divide optical signals—is crucial for those working in fiber optics, as it highlights their role in distributing signals across multiple paths while maintaining the integrity and quality of the light transmission.
