Selected Answer: B

It was on my exam (April 25th, 2024). An 'Optical Time Domain Reflectometer' (OTDR) is a fiber optic testing device used for identifying fiber break points, measuring cable lengths, and calculating relative optical power losses.

Selected Answer: B

An OTDR is a specialized tool used to test the integrity of fiber optic cables. It works by sending a pulse of light down the fiber and measuring the light that is reflected back. By analyzing these reflections, it can pinpoint the location of faults or breaks in the fiber. A. Loopback adapter: This tool is used for testing network ports by creating a loopback condition but is not suitable for testing fiber optic cables. C. Cable tester: While useful for copper cables, cable testers do not have the capability to measure and locate faults in fiber optic cables. D. New SFPs (Small Form-Factor Pluggables): SFPs are transceivers used to interface with fiber optic cables. Replacing them might resolve connectivity issues but will not help locate a break in the fiber.
