With the in-depth development of the information and data era, optical communication has also extended to many areas of life. With the advent of the 5G era, 40G/100G networks are widely used in data centers, and the installation and management of carrier-grade multimode fiber jumpers has become more and more important.

Fiber Cabling and Management
In the process of installing and arranging fiber jumpers, we should pay attention to the following aspects:
1. Do not bend the fiber jumper excessively, pay attention to its bending radius. When using, the minimum bending radius of the fiber is 30mm, and the bending radius that the MPO fiber jumper can withstand cannot be less than 10 times its diameter.
2. 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 end face of the jumper connector or the ferrule is contaminated, it can be wiped with absorbent cotton dipped in alcohol, otherwise the insertion loss will be affected.
3. During the installation process, the transceiver wavelengths of the optical modules at both ends of the fiber jumper must be consistent to ensure the accuracy of data transmission.
4. The laser signal is harmful to the eyes. Do not look directly at the end face of the ferrule when the signal is transmitted.
5. Do not pull or squeeze the fiber jumper. When installing a fiber jumper, excessive force will affect the performance of the jumper and the connectors at both ends.
6. When bundling and arranging carrier-grade multimode fiber jumpers, the tightness should be moderate to prevent extrusion due to excessive tightness.
7. Labeling is used for instructions. Correct labeling brings great convenience to later maintenance and management, and can quickly and accurately find the starting point and end point of each jumper.
8. When damage occurs due to man-made and other irresistible factors, the jumper should be replaced in time.
9. When the optical fiber network or system is abnormal, you can use the troubleshooting method to test one by one. You can usually use a light-passing 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 If it is more than 30% of the normal range, consider whether the end face of the ceramic core of the instrument is contaminated or damaged.
10. If the optical fiber jumper is used for the horizontal operation of the wiring center, it is recommended to choose the PVC outer quilt with good mechanical performance and moderate price, which has the characteristics of anti-oxidation and anti-degradation; it is usually used for the connection of the flat ground between buildings. The LSZH outer quilt with special flame retardant coating has the fire safety performance of low smoke, low toxicity and low corrosion.
Strengthening the management of optical fiber jumpers can not only increase the reliability and flexibility of optical fiber network systems, but also reduce the operation and maintenance costs of optical fiber networks.
