Cleaning Fiber Optic Transceivers: A Step by Step Guide

Fiber optic transceivers may seem solid and compact, however, you may run into some severe issues if you do not follow these cleaning steps.

To avoid severe issues, fiber optic transceivers need to be cleaned.

Optical transceivers may be small, however, they’re a result of highly sophisticated engineering and manufacturing. Although they may look solid and compact, dust and dirt can clog up the output side of the module.

If the connector end faces are not clean, you will run into some severe problems including data disruptions, optical impairments, and damages to the fiber core. This means that cleaning is an imperative step in utilizing transceivers.

Required cleaning tools:

  • Connector Cleaning Tips
  • 1-Click Fiber Optical Cleaner
  • Fiber End Face Inspector

Step 1:

Check the transceiver connector end face by using the end face inspector. You'll be able to see all the dust and dirt that has been built up on the output side of the module.

Step 2:

Insert the connector cleaning tip into the output side of the module. The gel will pick up much of the dirt inside.

Step 3:

Then, you’re going to take your one click fiber optical cleaner, which has a tiny microfiber end to pick up more dust, and insert that into the transceiver. Click the button once which will quickly vibrate the microfiber end to pick up the rest of the dirt.

Step 4:

Finally, check the inspector to see if the transceiver is clean. If it’s not, just repeat steps 2 and 3 until you don’t see anything on the inspector.


This is a very simple process, but at ProLabs, cleaning is an essential step in our testing and manufacturing processes. The cleaning process may vary depending on the transceiver's form factor, but overall, the process will be very similar.
