How to check whether the optical fiber jumper is qualified?
With the insertion loss instrument, first use the light pen to measure whether the jumper is through light, and determine that the fiber is not broken. The general indicators of carrier-grade test are: insertion loss is less than 0.3dB, and return loss is greater than 45dB.
The performance test of optical fiber jumper is divided into:
1. Optical performance detection
Including the return loss/insertion loss test, the test instrument can use the FibKey 7602 return loss/insertion loss integrated tester.
2. End geometry test
The test parameters include curvature radius, vertex offset, fiber height, etc. The test instrument is an interferometer, and many people use NorlandAC/NC3000 or CC6000 for testing. In particular, the CC6000 interferometer is used by more and more factories because of its superior cost performance.
3. Check optical fiber end scratches
Using video fiber magnifying glass for observation, such as many factories use FibView FV-400PA for inspection. The instrument gives the clearest images and is extremely simple to operate. There are also customers using FibKey-5600 variable magnifying glass for testing, the instrument set 400 times, 200 times, 80 times magnifying glass in one, can clearly and conveniently observe the optical fiber end face and core end face. Of course, you can also use the relevant software for automatic checks.
4. Optical fiber tension test
Test the tension that the optical fiber connector can withstand.
5. Ambient temperature experiment
You need to test the performance specifications of optical fiber connectors at different ambient temperatures.
