Optical fiber jumper plays an important role in the field of optical communication.
There are two judgment methods of optical fiber jumper: manual test and instrument test.
Manual test:
First, connect the two heads corresponding to the optical pen and the optical fiber jumper, then turn on the optical power switch to check whether there is red light at the other end. If there is red light, the optical fiber is normal; otherwise, the optical fiber is faulty. This method is easy to operate, but it can not be used for quantitative measurement.
Instrument test:
1. For optical fiber performance test, the return loss and insertion loss of optical fiber jumper can be measured by using optical power meter or optical time domain reflection grapher (general electrical level index of optical fiber: return loss is greater than 45dB, insertion loss is less than 0.3dB). In addition, when the optical fiber fails, these tools can also measure the breakpoint position of the optical fiber jumper, and quantitatively analyze the failure reason of the optical fiber jumper.
2. Fiber end scratch test: through the optical fiber magnifier, observe the fiber, you can see a clear image, and observe the fiber end scratch. It can also be tested with a variable magnification.
3. Optical fiber end geometry detection: through the use of interferometer and other instruments, the curvature radius, vertex offset, optical fiber height and other parameters are detected.
4. Optical fiber ambient temperature test: use optical fiber temperature measurement technology, use optical fiber temperature sensor and other instruments to test the performance of optical fiber connector in different temperatures and environments.
5. Optical fiber tension detection: optical fiber tension tester and other detection equipment can detect the maximum tension that optical fiber connector can bear, and then judge the performance of optical fiber.
There may be numerical instability in the test of optical fiber jumper. If the optical fiber and jumper are connected for measurement, it indicates that the fusion is not well done; if the test is only the optical fiber jumper, it indicates that the workmanship of the connector is not good enough. In addition, if the insertion loss value is not ideal during the test, data packet loss may occur in practical application.
