Precautions for the Use of Fiber Closure


The optical module at both ends of the fiber jumper must be the same length, that is, the two ends of the fiber must be the same wavelength. The simple distinction is that the color of the optical module must be the same. Generally, short-wavelength optical modules use multimode fiber, and long-wavelength optical modules use single-mode fiber to ensure data transmission accuracy.

The Fiber Closure must be cleaned with alcohol and cotton wool with the fiber jumper ceramic ferrule and ferrule end face before use. When used, the minimum bending radius of the fiber is less than 30mm. Protect the ferrule and the ferrule end face to prevent bumps and contamination, and bring the dust cap in time after disassembly. Do not look directly at the fiber end face while the laser signal is being transmitted. In case of damage caused by man-made and other force majeure factors, the damaged fiber jumper should be replaced in time.

Users should read the instructions carefully before installing the fiber closure, and install and debug under the guidance of the manufacturer or dealer. Do not over-bend and wrap the fiber during use, which will increase the attenuation of light during transmission. After the fiber jumper is used, the fiber connector must be protected with a protective cover. Dust and oil can damage the coupling of the fiber. If the fiber connector is dirty, you can use a cotton swab to clean the alcohol, otherwise it will affect the communication quality.

Abnormalities in the fiber optic network or system can be tested one by one using the troubleshooting method. You can do the continuity test when testing or troubleshooting the jumper. You can usually use the visible laser pointer to judge the entire fiber link. Or further use the precision fiber insertion loss loss detector to test its various indicators. If the indicator is within the qualified range, the jumper indication is normal, otherwise it is unqualified.
