Network connectivity in an extensive forest reserve was achieved using fiber optics. A network fault was detected, and now the repair team needs to check the integrity of the fiber cable. Which of the following actions can reduce repair time?
A.
Using a tone generator and wire map to determine the fault location
B.
Using a multimeter to locate the fault point
C.
Using an OTDR in one end of the optic cable to get the fiber length information
D.
Using a spectrum analyzer and comparing the current wavelength with a working baseline
Using an OTDR (Optical Time Domain Reflectometer) is the most effective way to reduce repair time when trying to locate a fault in a fiber optic cable. The OTDR sends a pulse of light down the fiber optic cable and measures the time it takes for the light to be reflected back. By analyzing the reflections, the OTDR can determine the location of any faults or breaks in the cable. This allows the repair team to quickly and accurately locate the fault point, which can significantly reduce the time needed for repairs.
The action that can reduce repair time when checking the integrity of a fiber cable in an extensive forest reserve is C. Using an OTDR in one end of the optic cable to get the fiber length information.
An OTDR (Optical Time-Domain Reflectometer) is a specialized instrument used to measure the integrity of optical fibers. By sending a pulse of light down the fiber, an OTDR can measure the time it takes for the light to reflect back and calculate the distance to any faults or breaks in the fiber. This can be used to determine the exact location of a fault, and help the repair team to fix the problem quickly and efficiently.
A. Using a tone generator and wire map is more suitable for copper cable and not for fiber cable.
B. Using a multimeter is not suitable for fiber cables, as it is used to measure electrical properties, while fiber cables use light signals to transmit data.
D. Using a spectrum analyzer is not a suitable method to locate fiber cable faults as it is used to analyze the frequency and amplitude of an electromagnetic signal, which is not used in fiber optic communication.
