How to test the performance of optical fiber jumper? Fiber optic jumpers are used as jumpers from equipment to fiber optic cabling links. It has a thicker protective layer and is generally used for the connection between the optical transceiver and the terminal box.
Pigtails are also called pigtails. Only one end has a connector, and the other end is a broken end of an optical fiber core. It is connected to other optical fiber cores by welding. It often appears in optical fiber terminal boxes and is used to connect optical cables and optical fiber transceivers. (couplers, jumpers, etc. are also used between them).
Optical fiber connector is a device for detachable (movable) connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. And to minimize the impact on the system due to its intervention in the optical link, this is the basic requirement of the fiber optic connector. To a certain extent, fiber optic connectors also affect the reliability and performance of optical transmission systems.
How to detect whether the optical fiber jumper is qualified
Use the insertion return loss meter to first test whether the jumper is transparent with a light pen, and make sure that the fiber is not broken. The general carrier-level test indicators: the insertion loss is less than 0.3dB, and the return loss is greater than 45dB.
The performance testing of fiber optic jumpers is divided into:
1. Optical performance testing includes return loss/insertion loss test, and the test instrument can use return loss/insertion loss integrated tester.
2. End face geometry test The tested parameters include radius of curvature, vertex offset, fiber height, etc.
3. Scratch detection on the end face of optical fiber Observation with a video optical fiber magnifying glass, the instrument can give the clearest image, and the operation is extremely simple. It can clearly and conveniently observe the condition of the fiber end face and ferrule end face. Of course, relevant software can also be used for automatic inspection.
4.Optical fiber pull test It is necessary to test the tensile force that the optical fiber connector can withstand.
