A fiber link connecting two campus networks is broken. Which of the following tools should an engineer use to detect the exact break point of the fiber link? A)OTDR. B)Tone generator. C)Fusion splicer. D)Cable tester. E)PoE injector.
The correct tool to use in this scenario to detect the exact break point of the fiber link is an Optical Time Domain Reflectometer (OTDR), option A.
An Optical Time Domain Reflectometer is a device used to analyse the characteristics of an optical fiber by sending a series of optical pulses into the fiber and measuring the reflections or backscattering of the light. This allows the engineer to precisely locate any faults or breaks in the fiber link.
Tone generator (B) is used to detect and trace electrical cables and is not applicable in this case as we are dealing with a fiber link.
Fusion splicer (C) is used for joining or splicing optical fibers together and does not help in identifying the exact break point.
Cable tester (D) is used to verify the connectivity and integrity of network cables, but it doesn’t provide information about the precise location of a break in a fiber link.
PoE (Power over Ethernet) injector (E) is used to power devices over an Ethernet connection and is not relevant to identifying a break in a fiber link.
Therefore, an OTDR is the most suitable tool for determining the exact break point of a fiber link.
