The transceiver wavelength of the optical modules at both ends of the optical fiber jumper must be the same, that is, the optical modules at both ends of the optical fiber must be of the same wavelength, and the simple way to distinguish is to have the same color of the optical modules.
The optical fiber should not be excessively bent and looped in use, which will increase the attenuation of light during transmission.
After the optical fiber jumper is used, the optical fiber connector must be protected with a protective cover. 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 it will affect the quality of communication.
1. Before use, the fiber jumper ceramic insert and insert end face must be wiped clean with alcohol and absorbent cotton.
2, the minimum bending radius of the optical fiber is less than 30mm.
3. Protect the core and the end face of the core to prevent damage and pollution, and put on a dust-proof cap in time after disassembly.
4. Do not look directly at the optical fiber end face when the laser signal is transmitted.
5. When man-made and other irresistible factors damage, the damaged optical fiber jumper should be replaced in time.
6, the optical fiber network or system is abnormal, you can use the fault elimination method to test one by one. When you test or troubleshoot the jumper fault, you can first perform an on-off test. Usually, you can use a visible laser pointer to light the entire fiber link. Or further use the precision optical fiber insertion loss return loss instrument to test its indicators, indicators within the qualified range, the jumper indication is normal, otherwise it is not qualified.
