How to conduct safety inspection on optical fiber jumper?

Optical fiber jumper is used to make jumper from equipment to optical fiber wiring link. It is often used between optical transceiver and terminal box. Network communication requires all equipment to be safe and unblocked. As long as a little intermediate equipment failure will cause signal interruption. Before use, it should be carefully detected. First, use the plug-in loss instrument to measure whether the jumper is illuminated with a light pen, determine whether the optical fiber is not broken, and measure the indicators. General electrical level indicators: the insertion loss is less than 0.3dB, and the singlemode loss is greater than 50dB. (it is recommended to use a good plug-in core to do it. The indicators are very good and the test is easy to pass!) In addition: some tips during the test are also helpful to measure the qualified optical fiber jumper!


The purpose is to find out the fault factors of optical fiber connection and reduce the fault of optical fiber connection system. The main detection methods include manual simple test and precision instrument test. This method of manual simple detection is to inject visible light from one end of the optical fiber jumper and see which one emits light from the other end. This method is simple but cannot be measured quantitatively. Precision instrument measurement: the required tools are optical power meter or optical time domain reflection grapher, which can measure the attenuation of optical fiber jumper and connector, and even the breakpoint position of optical fiber jumper. This measurement can quantitatively analyze the cause of the fault. When testing the optical fiber jumper, the value will be unstable. If only the optical fiber jumper is tested, the connector is not good enough; If the optical fiber and jumper are connected for measurement, it may be a problem in welding. If the insertion loss value is not very good during optical fiber test, it is easy to lose data packets when transmitting a large amount of data in actual use.
