Analysis and Countermeasures of Common Problems with MPO Fiber Jumpers

Issues that may occur with MPO jumpers

Damage to guide holes

This is mainly due to the tilting of the male end during connection, which may lead to scratches on the chamfered end of the male end guide pin, resulting in an increase in loss of some or all channels.

End-face pollution

This is mainly caused by removing the dust cap too early or being exposed to a non-clean environment for a long time before docking. This kind of pollution directly affects the performance of the product after docking, making the effect unstable, and even causing damage to the opposite connector during docking.

Mechanical damage to parts

This is mainly caused by excessive external force during construction. Although it may not affect the performance in the initial stage, it may result in total failure in a short period of time.

Mechanical damage to cable

This is mainly caused by dragging or inadvertent cutting during the construction process. Although it may not affect the performance in the initial stage, it may result in total failure in a short period of time.

Solutions to issues with MPO jumpers

To avoid the above faults and damages and further improve wiring connectivity and long-term stability, we need to pay attention to the following:

• Try to avoid opening the dust cap of the fiber jumper before docking.

  
  

• Try not to remove the dust cap of the adapter interface that has been connected to the adapter panel before docking.

  
  

• Except for normal docking, do not let the connector polishing end face come into contact with any other objects or be scratched.

  
  

• If there is visible end-face pollution, try to use special cleaning tools, or dust-free paper soaked in anhydrous ethanol for cleaning. Do not use paper towels, cotton balls, or ordinary cotton swabs for end-face cleaning.

  
  

• When connecting the connector, confirm the positioning key direction, and insert it into the socket panel axis after keeping the connector axial insertion. Do not repeatedly insert and remove it when the end face cannot be viewed.

  
  

• When inserting the MPO connector into the adapter, hold the tail sleeve of the connector and hold the outer shell of the connector when removing it.

  
  

• When bending the cable, keep the bending radius equal to or greater than 20 times the outer diameter of the cable.

  
  

• When bundling the cable, keep the appropriate tightness, and the outer skin of the cable should not show serious deformation.

  
  

• When perforating or threading the cable, use a push-pull method, and do not excessively drag or push the cable to prevent scratching or breaking the cable.
