CALIDAKA Fiber Optic Cleaner Pen 1.25mm & 2.5mm 2-Pack

CALIDAKA 2-pack fiber optic cleaner pens deliver fast, non-abrasive cleaning for LC (1.25mm) and SC/ST (2.5mm) connectors with over 800 one-click cleans per tool.

Keeping connector end faces free of dust, oil and residue is essential for reliable fiber links. These compact, one-click cleaning pens use a sealed microfiber tape reel and audible feedback to remove contaminants without scratching ferrules or lenses. Each pen measures 6.9 × 0.7 × 0.7 inches, comes in blue and white, and is compatible with STE2000-style one-click operation for field technicians, installers and lab users.

How quickly can I clean a connector with this pen?

The CALIDAKA pen is designed for rapid, repeatable cleaning with a single push action. A one-click mechanism advances the microfiber tape and performs a full cleaning cycle in seconds, so technicians can clear multiple end faces fast without disassembling jumpers or adapters.

• Over 800 cleaning cycles per pen from the sealed tape reel.
• One-click actuation—no extra tools needed.
• Audible click confirms a completed cycle.
• Works on assembled connectors to speed field work.

Will it damage delicate connector end faces?

No — the pen uses a soft microfiber tape formulated to lift dust, oil and particulates rather than abrading the ferrule or ceramic face. The cleaning surface is controlled so it removes contaminants without scratching, preserving connector alignment and optical performance.

• Microfiber tape avoids abrasive contact with end faces.
• Sealed internal reel prevents contamination transfer back to the connector.
• Clear window lets you inspect remaining tape to ensure fresh cleaning surface.

Which connector types and applications does it support?

This two-pen set covers the most common connector sizes used in telecom and data networks. One pen fits 1.25mm interfaces (LC) and the other is sized for 2.5mm interfaces (SC/ST), so you can prepare jumpers, patch panels and transceivers quickly on site or in the lab.

• Compatible with LC (1.25mm) and SC/ST (2.5mm) connectors.
• Ideal for patch cords, adapters, transceivers and field terminations.
• Compact 6.9×0.7×0.7 inch body stores in a tool kit or pocket.

How do I know when the pen is still usable?

A clear monitoring window on the pen’s housing shows the remaining microfiber tape so you can confirm available cycles before starting work. The pen also produces an audible click after each full cleaning rotation, giving tactile and auditory confirmation of proper operation.

• Transparent window reveals tape supply level.
• Audible click indicates completed cleaning action.
• Replace the pen when tape runs out to maintain cleaning effectiveness.

Who is this for? Field technicians, network installers, data center engineers and anyone who needs a fast, portable way to maintain optical links will benefit from the CALIDAKA fiber optic cleaner pens. They’re suited for routine maintenance, installation verification, and emergency troubleshooting where contaminated end faces can cause signal loss. The two-pen set ensures both 1.25mm and 2.5mm connector types are covered, helping teams minimize downtime and keep fiber connections performing reliably.
