Fiber optic power meter test procedure

The method shown is on the FOA Page Standard FOAwhich you may print or download and insert in your documentation. For other more typical multimode links of 5-dB, the two methods will generally give divergent . Equipment Needed To Perform This Test. Power meter for optical power testing.

Three of them use test sources and power meters to make the measurement, while the fourth and fifth use an OTDR.

The best way to understand them is to look at the diagrams below.

If measuring the actual receiver power on an installed system at the .

Bottom line: to certify an optical fiber cable you will need either an optical power meter and compatible light source(s), or an OLTS main-remote pair . While misunderstoo optical - fiber testing is one of the final and most important procedures in installing optical networks. Sources are NOT calibrated for launch conditions. We need to control the launch condition for multimode sources. This we refer to as Encircled Flux.

Have the right tools and test equipment for the job. Source and power meter , optical loss test set or test kit with proper equipment adapters for the cable plant you are testing. Reference test cables that match the cables to be tested and mating adapters, including hybrids if needed.

Fiber Tracer or Visual Fault Locator. Connect one end of the fiber to the light source and the other end to the power meter. At the other end of the cable, the power meter reads that light, and determines the amount of signal loss. Introduction to Testing Procedure. A well made connector will have a . Singlemode attenuation and optical return loss.

CommScope fiber solutions require the use of power meters that accept plugs of the type used to terminate the cabling system under test. This instrument has been carefully packed in accordance with standard shipping procedures. In the manual operating mode individual OLTStest sets can operate either as an optical power meter. Clean all fiber optic connectors before performing test procedures described below.

Optical power and loss testing.
