What function does a fiber identifier serve?

• A. Tones/Locate light fiber
• B. Measure attenuation
• C. Testing continuity
• D. Calibrating power

Answer: (A)

Identifying the correct fiber in a bundle by sensing the light traveling through it is what a fiber identifier is for. It’s a nonintrusive tool that clamps around a fiber and detects the presence of light, often giving an audible tone or visual cue to help you locate which fiber is active. This lets you work with the right fiber without disconnecting or damaging anything, which is especially useful at patch panels or in crowded cable runs. This function is distinct from measuring attenuation (which needs a light source and a power meter or OTDR to determine loss), testing continuity (which requires end-to-end connectivity checks), or calibrating power (which involves adjusting reference levels).
