Fiber optics for diagnostics and troubleshooting are used in varying capacities to test, measure, analyze, transmit, distribute, and/or simulate an optical signal with which the technician can perform procedures and processes associated with maintenance, problem solving, and calibration of equipment and/or networks. Normally in these applications, fiber optic products are used to create loop tests or transmit signals from point-to-point (either single-point to single-point, or single-point to multiple-points). For loop testing, commonly referred to as loopback testing, a signal is sent from a piece of equipment through a loopback or cable and returned to the source, simulating a complete network connection. This type of test allows technicians to perform function tests and internal diagnostic processes without the equipment being physically tied to an active network. This type of setup provides technicians with the advantage of easily isolating individual components for faster, more comprehensive analysis. With signal transmission applications, technicians generally use cables (multiple types for different applications) to connect one or more pieces of …show more content…
Inspect the fiber-optic cable by following it along its length. Look for bends in the cable, which obstruct the cable's optical fibers. Gently straighten any unnecessary bends.
2. Remove any objects resting on top of, or otherwise putting pressure on, the cable.
3. Check for excess tension in the cable. Fiber-optic cables should have some slack, as tension causes stress on the fibers. Slacken any cables that are pulled tightly.
4. Shorten cable spans that seem excessively long by placing connected devices closer together and using shorter fiber-optic cables.
5. Identify any splits, rips or tears in the cable. Replace any damaged cables with new fiber
