Although the use of optical fiber jumper is simple, its daily maintenance work cannot be ignored. Proper cleaning and maintenance not only ensure smooth signal transmission, but also extend the service life of the optical fiber to a certain extent.
Clean the fiber jumper in time

Why is fiber patch cord cleaning so important? An industry survey by a telecommunications giant pointed out that connector contamination is the primary cause of network failures. It can be seen that once the optical fiber is contaminated by dust, oil stains and other substances, the quality of optical signal transmission is greatly compromised. In addition, the metal particles produced by the abrasion of the connector body and the fiber shell may also block the fiber, causing signal loss and causing loss to the user. Therefore, it can be said that the optical fiber jumper is actually very "fragile", and timely cleaning is essential.

Generally speaking, the cleaning of fiber jumpers is mainly for the connectors at both ends. There are two main cleaning methods, namely dry cleaning and wet cleaning. There is a slight difference between the two and can be used together. 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.
Reasonable storage of optical fiber jumpers

Regardless of whether the fiber jumper is in use, the first thing to remember is: Do not bend or stretch excessively. This is a common mistake that everyone makes, and the worst result is to damage the jumper. Some damage caused by bending is visible to the naked eye. However, the loss in some cases 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 factor. Since this type of damage cannot be found directly, it is often overlooked and may cause even greater problems in the long run. In order to avoid further losses, when the jumper must be replaced, the following factors should be considered:

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

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

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

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.
