![]() ![]() Okay, so the light passed through the fiber what next? Now it’s time for further diagnostics to help in Identifying a fiber optic problem.Īmongst the list of typical fiber optic issues signal loss is a known perpetrator in fiber optic cable problems. ![]() You may still be able to use the fiber optic cable if the cable is not hundreds of meters long. So I see light at the end of the cable so cable must be good, right? Err No, this can be a simple indicator of the cable not being completely damaged. If no light is visible, then the fiber optic cable is broken and must be replaced.

Carefully remove the fiber optic cable connectors at both ends and shine either a laser pointer or bright flashlight in one end. Quick disclaimer! This isn’t the most scientific approach but if you don't have thousands of pounds of testing equipment this will may shed some light on the issue. So, let’s begin with a quick test to see if the fiber cable is any good. Faulty fiber connection in the splice tray or connection to the patch panel.Too many connectors or splices on a fiber optic cable can lead to loss of signal.A faulty splice or connectors can cause a great deal of signal loss."dirty" or contaminated connectors on fiber optic cables can cause extreme signal loss.Excessive loss of signal due to a long fiber optic span. ![]()
