Note On The Use Of Optical Fiber Jumpers
Feb 10, 2022
The transceiver wavelengths of the optical modules at both ends of the fiber jumper must be the same, that is to say, the two ends of the optical fiber must be optical modules with the same wavelength. In general, short-wave optical modules use multimode fibers (orange fibers), and long-wave optical modules use single-mode fibers (yellow fibers) to ensure the accuracy of data transmission.
Do not bend and loop the optical fiber excessively during use, which will increase the attenuation of light during transmission.
After using the optical fiber jumper, it is necessary to protect the optical fiber connector with a protective sleeve. Dust and oil will damage the coupling of the optical fiber.
If the optical fiber connector is dirty, you can use a cotton swab dipped in alcohol to clean it, otherwise the communication quality will be affected.
1. Before use, the ceramic ferrule and the end face of the ferrule must be wiped clean with alcohol and absorbent cotton.
2. The minimum bending radius of the optical fiber is not less than 150mm.
3. Protect the ferrule and the end face of the ferrule to prevent bumps and pollution, and put on a dust cap in time after disassembly.
4. Do not look directly at the fiber end face when the laser signal is being transmitted.
5. In the event of man-made and other irresistible damage, the damaged fiber jumper should be replaced in time.
6. Read the manual carefully before installation, and carry out installation and debugging under the guidance of the engineer of the manufacturer or dealer.
7. If the optical fiber network or system is abnormal, the troubleshooting method can be used to test one by one. When testing or troubleshooting the jumper, you can do the on-off test first. Usually, you can use a visible laser pointer to judge the entire fiber link. Or further use a precision optical fiber insertion loss and return loss instrument to test its various indicators. If the indicators are within the qualified range, the jumper indication is normal, otherwise it is unqualified.
