How to Troubleshoot Fiber Optic Cabling

Fiber Optic Cabling

Ensure that your fiber optic cabling is in the best working condition by following these troubleshooting steps.

Fiber optic cabling has become so ubiquitous in the networking world thanks to its ability to transmit huge amounts of data at the speed of light. Everything from home routers, personal computers, and audio-visual setups take advantage of the tech, and while many of the issues that come with traditional copper cables are circumvented with fiber, there are still issues that can develop. Thankfully, troubleshooting fiber optic cabling is easy provided you follow the below steps.

Inspecting Cables

If you suspect a specific cable is at fault, perform a visual inspection first. If you notice any excessive bends in the cabling, do what you can to straighten it out with a minimum of stress and make sure there are no spots where a lot of pressure is being applied to the cable. Fiber optic cabling should, for best performance, have a bit of slack, as tension can cause stress on fibers and reduce efficiencies. If you notice any splits, rips, or tears in your cables, they ought to be replaced outright. One tip for checking if a cable is physically damaged: shine light through one of the connectors of your cable using a qualified light source for that product. The light should shine through to the other side.

Troubleshooting Connections

Find where your fiber optic cable terminates on both ends, a fiber optic enclosure, workstation outlet or devices, like a television or router, and ensure that the connection is firmly secured. A single fiber optic cable may have multiple points of termination (fiber enclosure panels, fiber patch cords, work area outlets…), check all connections. It may be as easy as making sure the connector is seated properly or cleaning the connector tip (use of an appropriate, manufacturers recommended cleaning product is recommended).

General Tips

If possible, avoid running cables through high-traffic areas, footsteps and rolling chairs can both do damage to cables over time. Avoid bending, twisting or placing undo stress on fiber cables. Making sure that your cable management is as clean and neat as possible goes a long way in preventing damage as well. It’s generally best practice to avoid touching the connectors of your cables with uncovered fingers as well.
