Chinaopticcable about Optical detection

Optical detection system to connect the main purpose is to ensure the quality and reduce the failure factors, and failure to identify the fiber point of failure. Detection methods are many, mainly divided into artificial simple measurement and precision instruments to measure.

 A. artificial simple measurement: This method is generally used for rapid detection of optical on-off and construction to identify fiber made​​. It is a simple light into visible light from the fiber end, which one from the other end of the observation light to achieve. Although this method is simple, but it can not quantitatively measure the optical attenuation and fiber break.

 B. Precision measurement: using power meter or optical time domain reflectometer Tracer (OTDR) for quantitative measurement of the optical fiber can be measured fiber attenuation and splice attenuation, or even detect the location of fiber break. This measurement can be used to quantitatively analyze the reasons for failure of fiber networks and fiber optic networking products to evaluate.
