Significant Factors That Affect Optical Loss Testing Accuracy

If you’re determined to conduct fiber optic testing in your company, there are certain things that you need to know before anything. For starters, the accuracy of the results you get from these tests can be affected by certain factors.

To delve into detail, here’s a list of the things you need to keep an eye on:

The Test Reference Cord Connector You Used

Before you conduct a fiber optic test on your network, you should see to it that you’re using the right type of test reference cord connector. Moreover, it’s also necessary that you check the quality of the cord connector. It may not seem like it, but even the end-face geometry of your cord connector can create a massive impact on your fiber optic testing’s results. With that said, you should make sure that the test reference cord connector you use has met the precise radius of curvature and fiber protrusion if you want to get accurate results.

Compatibility of The Test Reference Cords and The Link Under Test

Another significant factor that can affect the optical loss measurement results you get is the compatibility of your test reference cords and link under test. A fiber mismatch is usually a result of existing fiber characteristics and independent techniques that are commonly used to join two optical fibers—this should be avoided to get the accurate results you want.

Characteristics of Light Source Used

If you want to get an accurate optical loss measurement, it’s important to keep an eye on your light source’s characteristics and how the light is coupled into the fiber optic cabling. In multimode fiber, the different distributions of launch conditions can give you different attenuation measurement results.
