MPO connector cleaning step

Updated on Mon Aug 18 2025

The MPO (Multi-fiber Push-On) connector is a high-density optical fiber connector used in many applications, including data centers, telecommunications networks, and high-speed computing. To ensure optimal performance and prevent signal loss, it is essential to keep MPO connectors clean. Here are the steps for cleaning an MPO connector:


Inspect the connector: Before cleaning the MPO connector, inspect it to see if it is damaged or dirty. Look for signs of damage, such as cracks or chips, and check if the connector is contaminated with dirt, dust, or other particles.


Prepare cleaning materials: To clean the MPO connector, you will need the following materials: lint-free wipes, 99% isopropyl alcohol, and a fiber optic cleaning cassette or a cleaning stick.


Clean the connector end face: Apply a few drops of 99% isopropyl alcohol to a lint-free wipe and gently clean the connector end face in a circular motion. Make sure to clean the entire end face, including the ferrule, without applying too much pressure. Avoid using alcohol with a lower percentage of purity, as it may leave a residue that can damage the connector.


Clean the connector guide pins: Use a fiber optic cleaning cassette or a cleaning stick to clean the guide pins on the MPO connector. Insert the cassette or stick into the connector and rotate it gently to clean the guide pins. Make sure to remove any dirt or debris from the pins.


Inspect the connector again: After cleaning, inspect the MPO connector again to make sure it is clean and free of damage. Use a fiber optic microscope to inspect the connector end face and the guide pins. If you notice any damage or contamination, repeat the cleaning process.


Reassemble the connector: Once the connector is clean, reassemble it carefully. Make sure the connector is properly aligned and seated securely.


Repeat for the other connectors: If you are cleaning multiple MPO connectors, repeat the process for each one.


Additional Tips:

Always use lint-free wipes and avoid using cotton swabs or tissues, as they may leave fibers on the connector that can damage it.

Use only high-purity isopropyl alcohol and avoid using other solvents or cleaners, as they may damage the connector.


Store the MPO connector in a protective case or sleeve when not in use to prevent contamination.


Clean the MPO connector regularly, especially if it is exposed to a dusty or dirty environment.


If you are unsure about how to clean an MPO connector, consult the manufacturer's instructions or seek the advice of a professional fiber optic technician.


Conclusion:

Cleaning MPO connectors is essential to maintain their performance and prevent signal loss. By following the steps outlined above, you can ensure that your MPO connectors are clean and free of damage, and that they will perform optimally. Remember to use high-quality cleaning materials, inspect the connector carefully, and clean it regularly to ensure that your fiber optic network runs smoothly.
