Precautions For Using Optical Fiber Jumper Patch Cord
The transmit and receive 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 of the same wavelength, and the simple way to distinguish is that the color of the optical module must be consistent. In general, short-wave optical modules use multimode optical fibers (orange optical fibers), and long-wave optical modules use single-mode optical fibers (yellow optical fibers) to ensure the accuracy of data transmission.
Do not excessively bend or loop the fiber during use, as this will increase the attenuation of light during transmission.
After using the fiber jumper, be sure to protect the fiber connector with a protective sleeve. Dust and oil will damage the coupling of the fiber.
If the fiber connector is dirty, you can clean it with a cotton swab dipped in alcohol, otherwise it will affect the communication quality.
1. The ceramic ferrule and the end face of the fiber jumper must be wiped clean with alcohol and absorbent cotton before use.
2. The minimum bending radius of the fiber when used is not less than 150mm.
3. Protect the ferrule and the end surface of the ferrule to prevent bumps and pollution. Bring a dust cap in time after disassembly.
4. Do not look directly at the end of the fiber when the laser signal is transmitted.
5. Replace the damaged optical fiber jumper in time when it is damaged by man-made or other force majeure factors.
6. Read the manual carefully before installation, and install and debug under the guidance of the manufacturer or dealer's engineer.
7. Abnormal situations in the fiber optic network or system can be tested one by one using the troubleshooting method. When testing or eliminating the jumper fault, you can do the continuity test first, and you can usually use a visible laser pointer to judge the entire fiber link. Or further use a precision optical fiber insertion loss return loss instrument to test its various indicators. If the indicator is within the qualified range, the jumper indicates normal, otherwise it is not qualified.
