One-Push Cleaner — A Practical Tool for Cleaning Connector

We know that the interface of each fiber optic component should be kept clean because dirt and dust can completely obscure the light wavelength and affect the network performance. For fiber optic connector, which plays an important role in a complete optical link, it is impossible to ensure that it does not get dirty. Therefore, cleaning connector is a key task. This post is going to introduce a practical tool for cleaning connector to you—one-push cleaner as well as how to use it.

Overview of One-Push Cleaner

The one-push cleaner is applicable for cleaning both connectors and adapters with one-push action. It utilizes dry cleaning without any alcohol and other harsh chemicals. In addition, the one-push cleaner uses the mechanical push action to advance an optical grade cleaning tape while the cleaning tip is rotated to ensure the fiber end-face is effectively, but gently cleaned. Simply insert the one-push cleaner into the connector or the adapter and push until you hear an audible “push”. According to different types of fiber optic connectors, there are three types of one-push cleaners—1.25mm LC/MU one-push cleaner, 2.5mm SC/ST/FC one-push cleaner and MTP/MPO one-push cleaner. The following part will focus on their structures and usages.

1.25mm LC/MU And 2.5mm SC/ST/FC One-push Cleaner

cleaner is an easy-to-use option for cleaning MU and LC connectors and exposed 1.25mm ferrules, while 2.5mm one-push cleaner is designed to clean SC, ST and FC connectors and exposed 2.5mm ferrules. The structure and usage of these two types of one-push cleaner are similar, so this part will only take 1.25mm one-push cleaner for example. As for the structure of 1.25mm LC/MU one-push cleaner, it can be divided into five parts—tip, nozzle, lock button, outer shell and guide cap. Tip is used to lead the cleaning cloth to the fiber optic connector and face; nozzle is used to lead the tip to the fiber optic connector and face; lock button is used to extend and contract the nozzle; outer shell is used to clean the fiber optic connector; guide cap acts as dust cap or cleaning adapter for connector plug. To have a better understanding of the structure of one-push cleaner and the function of each part, here is a figure for you.

In order to get high level optical performance, it is imperative that fiber optic connections are clean and free of contaminants. Fiber optic cleaning product is being highly recommended as a kind of very important tool for data center cabling. One-push cleaner is a practical tool for cleaning fiber end-face without the use of alcohol and it can be used for about 600 to 800 times. It is really a cost-effective solution for fiber optic connector cleaning.

Fiber Patch Cable Cleaning Recommendations

Fiber optics have expanded the capabilities and possibilities of networks beyond our expectation. Fiber patch cable serves as a common yet indispensable part which determines connection quality between fiber optic equipment, therefore it has no tolerance to any contaminant like dust and dirt. So keeping the end face of patch cables clean to ensure performance and reliability of the network is vital. This article offers general tips on patch cable cleaning, while introduces some professional tools that help simplify the process.

Why Is Patch Cable Cleaning Critical?

It is claimed that over 85% of fiber related problems in data centers, campus, and other enterprise or telecom environments are caused by contaminated connectors or end-faces. Which can often lead to degraded performance, or even worse, failure of the whole network system. So, cleaning consideration is always put in a paramount place in optical network transmission.

To ensure proper performance and reliability, care must be taken with the installation and maintenance of patch cable end face, as well as the removable fiber connectors. Because data are transmitted through the small core of the fiber patch cable, a very small amount of dirt or residue may significantly increase the connector’s attenuation and weaken the signal. Lack of applying proper patch cable cleaning procedures can directly impact the quality of the system’s performance.

General Tips for Patch Cable Cleaning

fiber patch cable cleaning is one of the most rudimentary and essential procedures to ensure network availability and reliability. The following lists some general suggestions when performing patch cable cleaning.

Point 1: Try to work in a clean area. Avoid working around heating outlets.

Point 2: Always keep dust caps on connectors and bulkhead adapters for as long as possible. Only remove the dust caps to clean the components prior to making a connection.

Point 3: Never touch the ferrule end face of a fiber optic connector. No matter what you do, you will leave contamination behind.

Point 4: Always clean connectors before inserting into an adapter. Use specialized cleaning tools or lint free pads and isopropyl alcohol to clean.

Point 5: Ferrules on the connectors/cables used for testing will get dirty by transference of contaminants from alignment sleeves in the bulkhead adapters, so test cables and adapters should be cleaned or replaced regularly when testing a large system.
