Using an insertion and return loss tester, first use a light pen to measure whether the jumper is illuminated to determine if the fiber optic is not broken. The measured indicators are generally electrical level indicators: insertion loss less than 0.3dB, return loss greater than 45dB.
The performance testing of fiber optic jumpers can be divided into:
1. Optical performance testing, including return loss/insertion loss testing. The testing instrument can use the FibKey 7602 integrated loss/insertion tester.
2. End face geometry testing, with parameters including curvature radius, vertex offset, fiber height, etc. The testing instrument is an interferometer, and many people use NorlandAC/NC3000 or CC6000 for testing. Especially due to its superior cost-effectiveness, more and more factories are using the CC6000 interferometer.
3. Scratches on the fiber optic end face are detected using a video fiber magnifying glass for observation, such as many factories using FibView FV-400PA for inspection. This instrument can provide the clearest image and the operation is extremely simple. Some customers also use the FibKey-5600 variable magnification mirror for testing. This instrument integrates 400x, 200x, and 80x magnifiers, allowing for clear and convenient observation of the fiber end face and plug end face. Of course, relevant software can also be used for automatic checks.
4. Fiber optic tensile testing requires testing the magnitude of the tensile force that the fiber optic connector can withstand.
5. Environmental temperature experiments require testing the performance indicators of fiber optic connectors under different environmental temperature conditions.
