Fibre Optic Continuity Test

The test source should match the type fiber generally led for mm or laser for sm and wavelength 850 1300 1550 nm that will be used on the fiber optic cable you are testing.

Fibre optic continuity test.

Ignatow is a senior technical analyst with sprint paranet dallas tx a nationwide network services provider owned by sprint. If they don t purchase 2 fiber optic jumper cables separately. Similar to a common flashlight in appearance a fiber optic tracer uses only a low wattage led light source or light bulb. A continuity check is one method for fibre optic testing and is done to ensure that the fibre has not been broken at any point or to check that the fibre under test does indeed go from one location to the correct destination.

Before installing your fiber optic network one of the most important steps that you can take to ensure that data will be transmitted properly is to test your cables and connectors for continuity this tutorial will help you find out if your fiber cables and connectors are fit for transmission in just a few simple steps. One basic type of fiber optics tester is known as a fiber optic tracer or visual fiber tracer. Test kits typically come with 2 jumper cables which you need to complete the test. For every fiber optic cable plant you will need to test for continuity end to end loss and then troubleshoot the problems.

When you test fiber optic cable networks a visible laser source connected to one end of the cable can be used to verify the transmission to the opposite end. This type of fiber optic test is only intended to detect gross fiber defects such as macrobends. A fiber optic tracer can be connected directly to the fiber optic cables that you re testing so that light can be sent through the cables. You also need 2 fiber optic patch panels.

Possibly the most frequently used method is to use a safe visible light source particularly a safe high power visible. If that light comes out the other end of the cables during a. A patch panel is basically an array of different ports for patching 2 cables together without splicing them like a breadboard. The visual fiber tracer can verify continuity of a fiber optic path including any connections and ensure fibers are unbroken.

An overview of fiber optic continuity tests. Shown here is the basic setup of a fiber optic link and the instruments you can use to test for fiber continuity even if you have no traditional continuity testing tools.
