Precautions for maintenance and cleaning of optical fiber jumpers.

 The contamination of the connector of the fiber jumper is an important cause of network failure. The fiber end face of the connector is contaminated by dust, which will result in poor optical signal transmission quality. Generally, the main location for cleaning the optical fiber is at the connector ports at both ends. There are two main cleaning methods, one is dry cleaning, and the other is wet cleaning. Commonly used dry cleaning tools include cassette-type fiber optic cleaning boxes and one-touch cleaning pens, and wet cleaning tools include dust-free wipes and cleaning sticks.

1. Store the fiber jumper correctly.



No matter whether the optical fiber jumper is in use or not, do not bend or stretch it excessively. Some damages caused by bending are clearly visible. However, in some cases, the loss may not be easily judged, such as micro-deformation of optical fiber caused by ultra-low temperature, millimeter-level displacement caused by defects of buffer or jacket, poor installation or Other factors. Because this type of damage cannot be found directly, it is often overlooked and will cause greater problems in the long run. To avoid further losses, we should pay attention to the following points:

(1) Do not bend the fiber jumper beyond its minimum bending radius, especially in the narrow space of high-density fiber wiring.

(2) Use appropriate tools to redesign the fiber jumper path to protect the cables from damage, such as horizontal cable management racks.

(3) Do not bump the optical fiber connector, otherwise the end face may be worn, and the fragments will pierce the skin. Therefore, it is recommended to put a dust cap on the jumper at any time.

(4) If you need equipment to detect and identify faults, such as damage and full attenuation inside the fiber jumper, you can use an optical time domain reflectometer (OTDR) and a fiber microscope.
