CompTIA Network+ (N10-009) — Question 70

A customer is adding fiber connectivity between adjacent buildings. A technician terminates the multimode cable to the fiber patch panel. After the technician connects the fiber patch cable, the indicator light does not tum on. Which of the following should a technician try first to troubleshoot this issue?

Answer options

• A. Reverse the fibers.
• B. Reterminate the fibers.
• C. Verify the fiber size.
• D. Examine the cable runs for visual faults.

Correct answer: A

Explanation

The best first step is to reverse the fibers, as a common issue can be incorrect connections, where the transmit and receive fibers are swapped. Reterminating the fibers is a more time-consuming solution that may not be necessary if the problem is simply a reversed connection. Verifying the fiber size and examining for visual faults are also important but should come after checking the basic connections.
