Fiber Optic Cleaner Pen OEM CLEP-25 for 2.5 mm Connectors SC/FC/ST/E2000

OEM CLEP-25 is a fiber optic cleaner pen designed for 2.5 mm connector endfaces including SC, FC, ST and E2000 types. The compact pen format provides a controlled, dry cleaning method to remove dust and contaminants from ferrules and endfaces without liquids. Intended for field and workshop use, it helps maintain signal quality and reduce connector loss during installation and maintenance.

Advantages

The cleaner pen offers a precise, single-action cleaning tip that fits 2.5 mm connectors and provides consistent removal of dust, oil and microscopic particles from optical endfaces. Its dry cleaning method eliminates the need for solvents, reducing the risk of residue and corrosion. The pen housing protects the cleaning media when not in use, and the compact design makes it convenient to carry in technician kits for on-site work.

Suitable for

• Field technicians performing fiber optic installation and maintenance
• Workshop environments where multiple connector types (SC/FC/ST/E2000) must be serviced
• Pre-connection cleaning before fusion splicing or connector mating
• Inspection and cleaning prior to testing or troubleshooting signal issues

Key specifications

• Connector compatibility: 2.5 mm ferrules (SC, FC, ST, E2000)
• Cleaning method: dry, lint-free, single-action pen tip
• Form factor: compact handheld pen for portable use
• Suitable environments: field and workshop applications
• Material: non-abrasive cleaning media designed for optical endfaces

How to use

Remove the protective cap and insert the pen tip gently into the connector ferrule. Apply light axial rotation or a single press according to the pen's designed action to sweep the endface and remove particulates. Inspect the connector endface with a microscope or inspection scope after cleaning; repeat if any residue remains. Replace the protective cap after use to preserve the cleaning media and avoid contamination.

Usage recommendations

Use the cleaner pen before every connector mating and after exposure to dusty or oily environments. Do not use excessive force; the pen is designed for gentle contact cleaning. Store in a dry, dust-free place and avoid contact with liquids or solvents. If heavy contamination or adhesive residue is present, consider a wet-cleaning procedure with appropriate solvent followed by dry cleaning and inspection.
