Common Issues in MPO Fiber Path Installation
The installation of MPO fiber paths often encounters several common issues, which mainly include the following aspects:
Damage to Guide Pin Holes: This typically occurs when the male connector is inserted at an angle, causing the front chamfer of the guide pin to scrape and potentially damage the pin holes. This can result in increased loss values for some or all channels.
Dirt and Contamination on End Faces: Premature removal of dust caps or prolonged exposure to unclean environments prior to connection can lead to unstable performance and even damage to the opposing connector.

Mechanical Damage to Components: Excessive force applied during installation can cause mechanical damage to components. Initially, this may not affect performance, but it can lead to complete failure in the short term.
Cable Mechanical Damage: Dragging or inadvertent cutting can cause mechanical damage to cables. Initially, this may not impact performance, but it can potentially lead to failure over time.
Incomplete Insertion of Connector Interfaces: If MPO connector interfaces are not fully inserted, it can result in a disconnected link. This requires re-insertion to ensure all lights are on and the link is functional.
Incorrect Sequencing or Contamination of Connector Ends: For example, incorrect sequencing of MPO connectors or contamination of their ends in ODF cabinets can lead to disconnected links or increased loss. This necessitates re-sequencing or cleaning of the end faces to restore link functionality.

To avoid these issues and ensure high connectivity rates and long-term stability, it is crucial to minimize the exposure of fiber jumpers to dust and dirt prior to connection, pay attention to operational details during cabling, and choose high-quality MPO fiber connectors that meet standards. Additionally, using appropriate installation methods and tools is also essential.
