Handheld fiber optic cleaner pen OEM CLEP-125 for 1.25 mm connectors (LC/MU) is engineered to remove dust and light contamination from connector endfaces without liquid solvents. The CLEP-125 performs dry cleaning of 1.25 mm ferrule connectors, providing a simple method to maintain optical signal quality and help reduce insertion loss. Its compact pen form factor and single-handed operation make it suitable for use in both field and laboratory environments, and the replaceable cleaning tip allows multiple cleaning cycles before replacement.

Advantages

The CLEP-125 offers targeted dry cleaning for LC and MU connectors in a compact, easy-to-operate pen. It enables quick, repeatable cleaning of connector endfaces with a replaceable tip to extend usable life. The device requires no liquids or solvents, reducing the risk of residue and simplifying maintenance procedures. Its handheld design supports fast access to connectors in patch panels, transceivers, and equipment racks.

Suitable for

• Field technicians performing on-site fiber connector maintenance
• Laboratory and bench testing where frequent connector cleaning is needed
• Telecommunications and data center maintenance on LC or MU terminated fibers
• Pre-installation and inspection routines to ensure clean endfaces

Key specifications

• Connector type compatibility: 1.25 mm ferrule connectors (LC, MU)
• Cleaning method: dry cleaning (no liquid or solvent required)
• Form factor: handheld pen with replaceable cleaning tip
• Operation: single-handed, manual actuation
• Intended use: endface cleaning of fiber optic connectors

How to use

Remove the protective cap and align the pen tip with the 1.25 mm connector ferrule endface. Gently insert the tip into the connector adapter or directly onto the connector and actuate the cleaning mechanism according to the pen design, typically by depressing or rotating the body to advance the cleaning element. Withdraw the pen, inspect the endface with a fiber microscope or inspection scope, and repeat if necessary. Replace the cleaning tip when effectiveness decreases or per the manufacturer’s guidance.

Usage recommendations

Use the CLEP-125 in a clean environment where possible and avoid excessive force when inserting the tip. Verify connector cleanliness after cleaning with a fiber inspection scope. Store the pen capped to protect the cleaning element and replace the tip when sign of wear or reduced cleaning performance appears.
