A. B. C. D. E.A.
The tool that should be used to detect the exact break point of the fiber link connecting two campus networks is an Optical Time Domain Reflectometer (OTDR).
An OTDR sends a high-powered pulse of light down the fiber optic cable and measures the amount of light that is reflected back. As the pulse of light travels along the fiber, it encounters any anomalies or defects in the cable, such as a break or a splice. The OTDR then measures the amount of light that is reflected back at each point along the cable, which provides information on the location and severity of any defects. This information can be used to pinpoint the exact location of the break point in the fiber link.
A tone generator, on the other hand, is a tool used to identify the location of a cable within a bundle or a wall. It works by sending a tone down the cable, which can be detected using a specialized probe. This can be useful for identifying the location of a cable, but it is not designed to locate a break in a fiber link.
A fusion splicer is used to join two fiber optic cables together by melting the ends of the fibers and fusing them together. It is not designed to locate a break in a fiber link.
A cable tester is used to test the continuity and quality of a cable, but it cannot locate a break in a fiber link.
A PoE injector is a device used to supply power to a network device over Ethernet cabling. It has no relevance to locating a break in a fiber link.
Therefore, the correct answer to the question is A. OTDR.
