A Full Introduction of MTP/MPO Connector Cleaning Solutions

Updated on Mar 6, 2021

MTP/MPO cables are now in great demand, since large enterprises and data centers are scrambling to migrate to 100G/200G/400G. As MTP/MPO connectors are more widely used for high density applications, the cleaning and maintenance of them also becomes a task that cannot be ignored. Dirt, dust and other contaminants on MTP/MPO connectors will greatly affect the transmission quality in a fiber link or even lead to network failure for the whole optical system. To maintain efficient connections among a wide range of devices, the following MTP/MPO connector cleaning solutions are highly recommended.

MTP/MPO Connector Cleaning Solutions

Generally speaking, there are two types of MTP/MPO connector cleaning methods, namely dry cleaning and wet cleaning. Thereinto, dry cleaning is more recomended, as wet cleaning may do harm to the equipment even though it can remove stubborn stains. Read How Much Do You Know About Fiber Connector Cleaning to learn more about these connector cleaning methods and the general cleaning procedures. Correspondingly, here a set of MTP/MPO connector dry cleaning and wet cleaning tools are introduced.

MTP/MPO Connector Dry Cleaning Tools

Despite of traditional dry wipes, some dry cleaning tools are developed for more effective and convenient uses.

Cassette Cleaner

It is also called reel-type fiber optic cleaner, designed with micro-fiber cloth that removes contaminants from ferrule end faces for single and multi-fiber male connectors.

NEOCLEAN-R2 Cassette Cleaner

This advanced NEOCLEAN-R2 cassette cleaner is produced by NTT-AT, which is well fitted for SC/FC/ST/LC/MU/MTP/MPO connectors. The cleaning cloth is robust enough to provide exceptional cleaning strength without fraying or leaving any fibrous material. Using a simplified tape advance mechanism, it allows smoother operation and cost reductions. In addition, it is made of anti-static material, offering excellent anti-static performance. And the operation is very easy. Just turn the winding reel to expose the new cleaning cloth and slide the connector on it. While, this cassette cleaner can be used for more than 400 cleanings and the tape is not replaceable.

Pen Cleaner

The MTP/MPO pen cleaner is designed for cleaning the ferrule end-faces of MTP/MPO connectors without the use of alcohol. With just an easy one-push operation, it can clean a variety of contaminants such as Arizona road dust, 70% IPA residue, distilled H2O residue, skin oil and so on. US Conec IBC™ Brand Cleaner MPO II and NEOCLEAN-M one-push pen cleaners are capable of cleaning MTP/MPO-8/12/24 connectors effectively at once, while US Conec IBC™ Brand Cleaner MTP®-16™ and NEOCLEAN-M2 one-push pen cleaners can clean MTP/MPO-16 connectors at a time. These MTP/MPO connector cleaners are suitable for cleaning ferrules with or without guide pins and cleaning both exposed connectors and connectors in adapters.

Watch the video or read the instructions below to learn how to use MTP/MPO-8/12/24 one-push cleaner for exposed connectors and connectors in adapters.

Cleaning Procedures for Exposed Connectors

Step 1: Open the protective cap of the attachment at the tip of the cleaner.

Step 2: Insert the connector into the cleaner.

Step 3: Press the cleaner until hearing a click sound.

Step 4: Inspect the connector using a fiberscope if permitted.

Cleaning Procedures for Connectors in Adapters

Step 1: Take off the attachment.

Step 2: Insert the cleaner tip into the MTP/MPO adapter.

Step 3: Press the cleaner until hearing a click sound.

Step 4: Inspect the connector using a fiberscope if permitted.

MTP/MPO Connector Wet Cleaning Tools

Traditional wet cleaning tools are for exposed single and multi-fiber connectors such as LC/SC/FC/ST/MU/MTP/MPO etc. Commonly used ones are cleaning wipes and foam swabs.

Kimtech Science Kimwipes

This cleaning wipe is made of pure virgin wood fiber with a dispenser box that allows drawing out wipes one-at-a-time and preventing electrostatic shock. Used with isopropyl alcohol, this lint-free and non-abrasive wipe is ideal for MTP/MPO connector end face cleaning without the risk of scratching or lint residue.

Foam Swabs

These lint-free foam swabs are ideally suitable for cleaning contaminants from almost all fiber connectors due to its low price, easy operation and excellent cleaning performance. The basic cleaning procedures are as follows: dip a cleaning swab in isopropyl alcohol; insert the swab into the MTP/MPO connector; lightly press and turn the swab to clean the ferrule end face; follow up with a dry swab to ensure a thorough cleaning.

No matter dry cleaning or wet cleaning methods, the ultimate purpose is to keep the high quality transmission in fiber optic links. As for MTP/MPO connectors, dry cleaning tools such as cassette cleaner and one-push cleaner are quite effective and convenient. Wet cleaning using cleaning wipes or foam swabs with isopropyl alcohol is also useful but more aggressive. Choosing the suitable tool is important, but don't forget the golden rule of fiber cleaning either. Remember that the act of cleaning itself is a potential source of contamination, so the golden rule is to always inspect, clean and inspect again.
