Fiber optic jumpers are used as jumpers from devices to fiber optic cabling links, and are often used between optical terminals and terminal boxes. The communication of the network requires the safety and smoothness of all devices, and any intermediate device failure will cause signal interruption. Before use, it is necessary to carefully inspect. First, use a power loss tester to measure whether the jumper is connected to light and confirm that the fiber is not broken. The general electrical level indicator is that the insertion loss is less than 0.3dB and the return loss is greater than 45dB. (It is recommended to use good plugs for testing, as the indicators are good and it is easy to pass the test!) Also, some tips during testing can help to detect qualified fiber optic jumpers!
Fiber optic jumper detection is to ensure the quality of system connections, reduce fault factors, and identify the fault point of the fiber optic when a fault occurs. The main detection methods include manual simple testing and precision instrument testing. Artificial simple detection is achieved by inserting visible light into one end of the fiber optic jumper and observing which one emits light from the other end. This method is simple but cannot be quantitatively measured. Precision instrument measurement: The required tools include an optical power meter or an optical time-domain reflection plotter, which can measure the attenuation of fiber optic jumpers and joints, and even measure the breakpoint position of fiber optic jumpers. This measurement can quantitatively analyze the cause of the malfunction. When testing fiber optic jumpers, there may also be unstable values. If only fiber optic jumpers are being tested, then the connectors are not well made; If the optical fiber is connected to the jumper for testing, it may be a problem with the fusion connection. If the insertion loss value is not good during fiber optic testing, it is easy to lose data packets when transmitting a large amount of data in practical use.
