Which of the following tools would you use to cut fiber optic cables?

The fiber optic cleaver is specifically designed for cutting fiber optic cables cleanly and accurately. Unlike standard cutting tools, a cleaver ensures that the fiber ends are flat and smooth, which is essential for effective splicing and minimizing loss of signal when cables are joined. The precision of a cleaver allows for the proper preparation of the fiber ends, which is crucial in maintaining the integrity of the optical signal transmitted through the fibers.

Other tools mentioned have different purposes related to fiber optics: an optical power meter is used for measuring the power in optical fibers, a fusion splicer is used for joining two fibers together by melting them together, and an OTDR (Optical Time Domain Reflectometer) is utilized for testing and troubleshooting fiber optic systems by sending pulses of light through the fiber and measuring the reflections. None of these tools is intended for cutting the cables themselves, which is why the cleaver is the correct choice for this task.
