The quality of fiber patch cord management directly affects the overall data transmission. Managing fiber patch cords can not only reduce the operating cost of the entire fiber optic network, make it beautiful and convenient, but also increase the reliability and flexibility of network operation and maintenance.
In the process of installing and arranging optical fiber jumpers, we should pay attention to the following aspects:
1. Do not pull or squeeze the fiber jumper. When installing an optical fiber jumper, excessive force will affect the performance of the jumper and the connectors at both ends.
2. Do not bend the fiber jumper excessively, pay attention to its bending radius. When in use, the minimum bending radius of the optical fiber is 30mm, and the bending radius that the MPO fiber jumper can withstand cannot be less than 10 times its diameter.

3. When there is an abnormal situation in the optical fiber network or system, you can use the troubleshooting method to test one by one. You can usually use a light pen to test the continuity, or use a precision instrument to test the insertion loss and return loss. If you continuously test the insertion loss of 3 jumpers More than 30% of the normal range, consider whether the end face of the ceramic core of the instrument is contaminated or damaged.
4. During the installation process, the transceiver wavelengths of the optical modules at both ends of the fiber jumper must be the same to ensure the accuracy of data transmission.
5. Pay attention to protect the ferrule during installation and use to prevent collision and pollution. Wear a dust cap in time after disassembly. If the jumper connector or the end face of the ferrule is contaminated, you can use absorbent cotton dipped in alcohol to wipe it, otherwise it will affect the insertion loss.
6. When bundling and arranging optical fiber jumpers, the tension should be moderate to prevent squeezing caused by over-tightening.
7. Labeling as instructions, correct labeling brings great convenience to later maintenance and management, and can quickly and accurately find the starting point and ending point of each jumper.
8. When there is damage caused by man-made or other irresistible factors, the jumper should be replaced in time.
9. The laser signal is harmful to the eyes. Do not look directly at the end face of the ferrule during signal transmission.
