How are fiber optic patch cords tested for safety?

ONE. How can fiber optic patch cords be tested for safety? Fiber optic patch cords are used to make patch cords from equipment to fiber optic cabling links. The communication of the network requires the safety of all equipment smooth, as long as a little intermediate equipment failure will cause signal interruption. So before using it to be very careful testing, with the insertion of back loss instrument first with a light pen to measure whether the jumper is through the light to determine the fiber is not broken, measured indicators. Fiber optic patch cord testing is to ensure the quality of the system connection, reduce the failure factors, and in the event of a failure to find the failure point of the fiber. The main detection methods are simple manual testing and precision instrument testing. Artificial simple detection of this method is from one end of the fiber optic patch cord into the visible light, from the other end to see which one of the light to achieve. Precision instrumentation: the tools required are optical power meter or optical time domain reflection icon, can measure the attenuation of the fiber optic patch cord and the attenuation of the connector, and even measure the location of the fiber optic patch cord break point. Precision instrumentation measurements can be quantitatively analyzed to determine the cause of the failure. When testing fiber optic patch cords, there will be unstable values now, if the test is only fiber optic patch cords, then it is not good enough to do the joints; such as fiber optics and patch cords connected to the test, then it may be fusion splicing in the problem. Fiber testing, if the insertion loss value is not very good, the actual use of large amounts of data in the transmission of data is easy to lose packets.
