The transceiver wavelength of the optical module at both ends of the multimode fiber jumper must be consistent, that is to say, the two ends of the fiber must be the optical module of the same wavelength. The simple method of discrimination is that the color of the optical module should be consistent. In general, the short-wave optical module uses multi-mode optical fibers (orange optical fibers), and the long-wave optical module uses single-mode optical fibers (yellow optical fibers) to ensure the accuracy of data transmission.
The fiber should not be bent and looped excessively in use, which will increase the attenuation of light during transmission.
The multimode fiber jumper must be protected with a protective sleeve after use, dust and oil will damage the coupling of the fiber.
If the fiber connector is dirty, you can use a cotton swab dipped in alcohol to clean, otherwise it will affect the quality of communication.
1. Before use, the fiber jumper ceramic core and the end face of the core must be wiped clean with alcohol and fat-free cotton.
2. The minimum bending radius of the fiber is less than 30mm when used.
3. Protect the core and the end face of the core, prevent damage and pollution, and wear the dust cap in time after disassembly.
4. Do not look directly at the end of the fiber when the laser signal is transmitted.
5. The damaged fiber jumper should be replaced in time when man-made and other irresistible factors are damaged.
6. Before installation, read the instructions carefully, and install and debug under the guidance of the manufacturer or dealer's engineer.
7, optical fiber network or system abnormal situation, can use the fault elimination method one by one test. When testing or eliminating jumper fault, you can first do the on-off test. Usually, you can use the visible laser pointer to light the entire fiber link. Or further use precision fiber insertion loss back loss instrument, test its indicators, indicators within the qualified range, the jumper is normal, otherwise unqualified.
