How Much Do You Know About Fiber Connector Cleaning?

Posted on by FS.COM

With the widespread use of optical fiber in high-speed communications, reliable and efficient fiber installations and maintenance are critical to the high-performance network. According to NTT-Advanced Technology, 98% of installers and 80% of network owners reported that issues with fiber connector contamination were the greatest cause of network failure. Contaminated or dirty fiber connectors can often lead to degraded signal performance or link failure, so a properly maintained and cleaned fiber optic cable will help to reduce the contamination on fiber interface. Admittedly, fiber cleaning kits play an important role in the maintenance of fiber optic system, which keeps the effective connections between all fiber optic equipment.

Causes for Network Failures

Different Fiber Connector Types

As we all know, fiber connector is a component to terminate the end of fiber optic cable, which has an important impact on the fiber optic transmission reliability and the performance of the system. In general term, about 100 fiber optic connectors have been introduced to the market. But the most commonly used fiber connector types include LC, SC, MU, ST, FC, MTRJ, NID, E2000 and MTP/MPO connector. Therefore, choosing the right fiber cleaning tools depends on the types of the fiber connector. For more information about fiber connector, please refer to How Many Fiber Connector Type Do You Know?

General Fiber Cleaning Procedures

Before cleaning the fiber optic connectors, it is essential to know the general connector cleaning process. Generally, there are two methods to clean fiber connectors: dry cleaning and wet cleaning. Dry cleaning is to use a reel-type cassette cleaner or push-type fiber cleaner to wipe the connector end face against a dry cleaning cloth in one direction. It can remove airborne contamination and should be attempted at first. As for wet cleaning, first wipe the end face against the wet area and then onto a dry area to clean potential residue from the end face. Wet cleaning is more aggressive than dry cleaning, but it can remove both airborne contamination and light oil residue. After dry cleaning, the connector is still dirty, a wet cleaning is followed immediately in order to ensure no residue is left on the end face. The following shows the fiber connector cleaning process:

Note: Wet cleaning is highly discouraged for receptacles and bulkheads due to the fact that damage to equipment can occur.

How Many Fiber Connector Cleaning Solutions Are There?

Reel-type Fiber Cleaners

The reel-type cleaner is designed for effective cleaning of almost all fiber optic connectors with an accessible ferrule including LC, MU, SC, FC, ST, MPO/MTP, MTRJ and so on. If you only need to clean the accessible connector with a wide range of connector styles, it is an ideal choice for you.

CLE-BOX cassette cleaner is an essential non-alcohol cleaner to maintain and guarantee good quality of fiber optic connection. It supports removing dust, oil, and other debris for LC/SC/FC/ST/MU/D4/DIN connectors. You don’t have to carry any other tools to clean the dust and grease on optical fiber interface. Cassette tapes are available for replacement after 500+ cleaning operations to ensure low cleaning cost. When using cassette cleaner, please always remember that don’t reverse cleaning direction so as to avoid back wiping contaminants.

Fiber Cleaning Wipes

Fiber optic cleaning wipes are designed to be used dry or with fiber optic cleaning alcohol for effectively removing common contaminants from optical jumpers and patch cords. These fiber wipes are lint-free and non-abrasive, thus they can provide superior cleaning of fiber optic connector ferrules without risk of scratching or lint residue. FS.COM can provide Wipexperts M-3 cleanroom wipes, cleanroom wipes, and Kimtech wipes. Among them, Kimtech science wipes have been a favorite choice of labs, medical offices and delicate manufacturing for more than 60 years. Kimwipes delicate task wipers are specifically designed to gently clean liquid and dust and are great for instrumentation, surface, parts and lens cleaning.

Foam Swabs

Fiber optic lint-free foam swabs are ideally suited for cleaning contamination from 1.25mm or 2.5mm fiber adapters and connectors. 1.25mm and 2.5mm foam swabs are all made of polyester and polyurethane. These small foam swabs have excellent performance for cleaning the end face of adapter or connector, and they can also be used in other equipment, such as a printer, computer, optical instrument camera lens, etc.
