Which device creates connections between two fiber optic cables to ensure continuity of communication between telecommunication devices?

• A. VFL
• B. Optical Fiber Fusion Splicer
• C. Punchdown Tool
• D. Butt Set

Answer: (B)

This question tests how a fiber optic link is physically joined to maintain signal continuity. The Optical Fiber Fusion Splicer is the device that actually fuses the ends of two fiber cables together, aligning them precisely and creating a controlled arc to fuse the glass. The result is a seamless, low-loss splice that preserves the optical path for continuous communication between devices. The other tools serve different roles. A Visual Fault Locator sends light down a fiber to locate breaks or faults but doesn’t join fibers. A punchdown tool is used to terminate conductors on patch panels or distribution blocks, not to fuse fiber. A butt set is a copper telephone-testing device, not used for fiber optics.
