Optical fiber is how to test

Optical fiber is how to test for optical testing's main purpose is to ensure that the quality of the system is connected, reduce fault factors and fault, find out when the fault point of the optical fiber. Testing method are many, mainly divides into artificial simple measurement and precision instrument measurement.


1. Artificial simple measurements:

This method are used for rapid detection of the optical fiber to break and construction of the optical fiber used to distinguish. It is to use a simple light source from one end of the optical fiber into visible light, and from the other end see which shine a root to realize. This method is simple, but it can't quantitative measure of fiber optical attenuation and the breakpoint.

2. Precision instrument measurement:

Use light power meter or light reflected the time domain instrument (OTDR) quantitative measurement of optical fiber, can detect the attenuation and joint of the attenuation, and even can measure the position of the breakpoint. Fiber This measure can be used to quantitative analysis of the optical fiber network failure reason and optical fiber network products evaluation.
