Possible problems with MPO fiber optic jumpers

The research and development of MPO fiber optic connectors and the application in practical engineering have an important role and significance, greatly improving the popularity of optical networks and reducing costs, and are very important applications in optical fiber communication networks, transmission systems, and CATV networks.


At the same time, the application of MPO fiber jumper high-density wiring in practical engineering has an important role and significance. The use of MPO fiber jumper is a very particular knowledge and skill, and it is also a very important link.

Possible problems with MPO fiber optic jumpers


  1. Guide pin hole damage


The main reason is that the insertion direction of the male connector is inclined during connection, and the chamfering of the front end of the guide pin of the male connector is scratched. This kind of damage can directly lead to the increase of some or all channel loss values.


Second, the end surface is dirty

It is mainly caused by the premature removal of the dust cap before docking or long-term exposure to an unclean environment. Such dirt will directly affect the docking performance of the product, making the effect unstable after docking, and even causing damage to the opposite joint during docking.


  1. Parts mechanical damage


It is mainly caused by the excessive application of external force during the construction process. This type of damage may not affect the performance in the initial stage, but it will basically fail completely in the short term.


  1. Cable mechanical damage


If it is mainly caused by dragging or unintentional cutting during the construction process, such damage may not affect the performance in the initial stage, but it will basically fail completely in the short term.

In order to avoid the above damage and improve the wiring completion rate and long-term stability, the following points should be paid attention to during the wiring process:


  1. Try to avoid opening the dustproof cap of the fiber jumper before docking. Try not to remove the dust cap from the adapter interface that has been connected to the adapter panel and has not yet been docked. Do not allow the connector ground face to come into contact with or be scratched by anything other than normal mating.


  1. If there is foreseeable contamination on the end surface, try to use special cleaning tools or dust-free paper soaked in absolute ethanol to clean the end surface. Do not use paper towels, cotton wool, ordinary cotton swabs and other items to clean the end surface.


  1. When docking the connector, confirm the direction of the connector positioning key and insert the adapter or socket panel axially, and do not insert and pull out repeatedly when the end face cannot be viewed. When the MPO connector is inserted into the adapter, pay attention to hold the tail sleeve of the connector, and hold the housing of the connector when pulling it out.


  1. When bending the cable, keep the bending radius equal to or greater than 20 times the outer diameter of the cable. When bundling the cables, keep the tightness appropriate, and the cable sheath should not be severely deformed. When piercing the cable and threading the pipe, use the method of pushing and pulling at the same time. Do not drag or push the cable vigorously to prevent scratches that may cause the cable to break or break.
