MTP/MPO Connector Cleaning: One-Click Cleaner vs. Cassette Cleaner

With data centers moving to 40G/100G, MPO fiber cables are extensively deployed. To ensure the reliable and efficient performance of the MPO cables, it is critical to clean the MPO connectors before mating to other equipment as contaminated connectors would lead to degraded performance and costly but preventable failures. There are two ways to clean MTP/MPO connectors. One is to use cassette cleaner, while the other is to use one-click cleaner. This post will talk about these two types of cleaning methods for MTP/MPO connectors.

One-Click Cleaner vs. Cassette Cleaner: Using Rules

The one-click cleaner for MTP/MPO connectors is a cost-effective tool for cleaning fiber end-faces without the use of alcohol. It can clean both exposed jumper ends and connectors in adapters with one-push action. A cassette cleaner contains a refillable lint free reel of cloth that is moved after each cleaning, always presenting a clean surface. It is applicable primarily for cleaning connectors with one-wipe action in dry cleaning without any alcohol and other harsh chemicals.

One-Click Cleaner vs. Cassette Cleaner: Cleaning Procedures

For both the two cleaning methods, please always inspect before cleaning. If the connector is already clean, there is no need to clean it.

Cleaning Procedures of One-Click Cleaner (For Connectors in Adapters)

• Pull off the guide cap.
• Insert the cleaning tool into the bulkhead and turn the cleaning wheel backwards until click two times.

Cleaning Procedures of One-Click Cleaner (For Exposed Connectors)

• Carefully pull out the guide cap cover.
• Insert the patch cord into the cleaning tool, apply slight pressure and turn the cleaning wheel backward until click two times.

Cleaning Procedures of Cassette Cleaner

• Remove connector dust cover.
• Select the appropriate cleaner for male/female.
• For female MTP/MPO connectors, use the cleaning brush and fluid to remove any debris from the pin holes.
• Depress the lever so that a fresh area of cleaning cloth is exposed.
• Position the ferrule against the cloth so that the fibers are in contact with the cleaning material. In the case of angled connectors, the ferrule will need to be adjusted accordingly.
• Wipe the connector in the direction shown on the cassette.
• Release the grip to seal off the cleaning cloth.
• Let the ferrule air-dry before inspecting with a 200xmicroscope.
• If still contaminated repeat all steps once again.
• Ensure that the connector does not touch any hard surfaces.

Note: Do not move connector back and forth. Connector is to be moved in only the direction of the arrows on the cleaner.

One-Click Cleaner vs. Cassette Cleaner: Which to Choose?

From what have described above, we can summarize that one-click cleaner can be used for connectors in adapters and exposed connectors, while cassette cleaner is only applicable for exposed connectors. Moreover, the one-click cleaner is capable of cleaning ferrules with or without guide pins. But for cassette cleaner, you should choose the correct type to clean male or female connectors. In my opinion, one-click cleaner is more convenient. Among the two, which is your choice?

Fiber Optic Cable and Connector Cleaning Guide

Why Is Fiber Optics Cleaning Important? 

Reliable and efficient fiber installations are critical to the high performance network. Cleaning fiber optic components is essential for quality connections between fiber optic equipment. It is one of the most basic and important procedures for the maintenance of fiber optic systems, because any contamination in the fiber optic connection will cause failure of the component or failure of the whole system. Some basic cleaning procedures for fiber optic cable and connector will be described in this article.

Fiber Optic Connector Cleaning Steps

Step 1: Inspect the fiber optic connector, component, or bulkhead with a fiberscope.

Step 2: If the connector is dirty, clean it with a dry cleaning technique.

Dry cleaning: Using a reel-based cassette cleaner (see the picture below) with medium pressure, wipe the connector end face against a dry cleaning cloth (single swipe per exposure) in one direction. For angled physical contact (APC) polished connectors, ensure that the entire end face surface mates with the cleaning cloth. Dry cleaning will generally remove airborne contamination and should be attempted first. Inspect the connector end face for contamination after cleaning.

Step 3: Inspect the connector.

Step 4: If the connector is still dirty, repeat the dry cleaning technique.

Step 5: Inspect the connector.

Step 6: If the connector is still dirty, clean it with a wet cleaning technique followed immediately with a dry cleaning in order to ensure no residue is left on the end face.

Wet cleaning: Lightly moisten a portion of a lint free wipe with fiber optic cleaning solution (or > 91% Isopropyl Alcohol) and applying medium pressure, first wipe the end face against the wet area and then onto a dry area to clean potential residue from the end face. For APC polished connectors, ensure that the entire end face surface mates with the cleaning wipes. Wet cleaning is more aggressive than dry cleaning, and will remove airborne contamination as well as light oil residue and films.

Step 7: Inspect the connector again.

Step 8: If the contaminate still cannot be removed, repeat the cleaning procedure until the end face is clean.

Note: Never use alcohol or wet cleaning without a way to ensure that it does not leave residue on the end face. Or it will cause equipment damage.

Fiber Optic Patch Cords Cleaning Steps

Step 1: Make sure that the lasers are turned off before you begin the inspection.

Warning: Invisible laser radiation might be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.

Step 2: Remove the protective end cap and store it in a small resealable container.

Step 3: Inspect the connector with a fiberscope.

Step 4: If the connector is dirty, clean with a cartridge or pocket cleaner.

Reminder: For cartridge cleaners, press down and hold the thumb lever. The shutter slides back and exposes a new cleaning area. For pocket cleaners, peel back protective film for one cleaning surface. For manual advance cleaners, pull on the cleaning material from the bottom of the device until a new strip appears in the cleaning window.

Step 5: Hold the fiber tip lightly against the cleaning area.

Reminder: For single, non−APC fiber connectors, rotate the fiber once through a quarter turn, 90 degrees. For APC connector end faces, hold cleaning area at the same angle as the end face.

Step 6: Pull the fiber tip lightly down the exposed cleaning area in the direction of the arrow or from top to bottom.

Warning: Do not scrub the fiber against the fabric or clean over the same surface more than once. This can potentially contaminate or damage your connector.

Step 7: Release the thumb lever to close the cleaning window, if you use cartridge type cleaners.

Step 8: Inspect the connector again with the fiberscope.

Step 9: Repeat the inspection and cleaning processes, as necessary.

Warning: Throw away any used cleaning material, either cards or material cartridges, after use.

Summary

As cleaning is important for fiber optic network, choose the suitable cleaning tools for the fiber optic connectors and fiber optic patch cords would be significant.
