The main purpose of optical fiber jumper detection is to ensure the quality of system connection, reduce fault factors, and find the fault point of optical fiber when the fault occurs. Commonly used detection tools for optical fiber inspection are: red light pen, optical power meter, optical fiber inspection microscope and OTDR optical time domain reflectometer.
Manual and simple measurement: This method is generally used to quickly detect the on-off of the jumper, and distinguish the jumper made during construction. It uses the light source of the red light pen to input visible light from one end of the fiber patch cord and observe the light emitted from the other end. Although this method is simple, it cannot quantitatively measure the attenuation of the patch cord and the breakpoint of the fiber patch cord.
Precision Instrument Measurements: Quantitative measurements of patch cords using an optical power meter or optical time domain reflectometry (OTDR) can measure patch cord attenuation and connector attenuation, and even measure patch cord breakpoint locations. This measurement is available It is used to quantitatively analyze the causes of optical fiber network failures and evaluate optical fiber network products.
