NTT-AT Launches "CLETOP Station," a Stationary Automatic Optical Connector Cleaner

NTT Advanced Technology Corporation (NTT-AT), headquartered in Shinjuku-ku, Tokyo, and led by President and CEO Tadashi Ito, announced on July 15, 2026, the launch of its stationary automatic optical connector cleaner, "CLETOP Station" (hereinafter referred to as "this product"), designed for high-quality cleaning of optical connector end faces.

This product supports both dry and wet cleaning, achieving stable cleaning quality even for difficult-to-clean targets such as multi-fiber ferrules.

Based on the cleaning technology cultivated by NTT-AT, this product contributes to improving quality and operational efficiency in manufacturing and inspection processes.

1. Background

With the increasing speed and capacity of optical communications, the impact of optical connector end face cleaning quality on communication quality and measurement accuracy is growing. Manufacturing and inspection processes require a reduction in measurement variations and defects caused by end face contamination.

2. Product Overview

This desktop optical connector end face cleaner features a stationary design. By automatically controlling stable cleaning conditions and operations according to the optical connector being cleaned, it achieves high reproducibility and uniform cleaning quality.

3. Product Features

(1) High-Function Cleaning Supporting Both Dry and Wet Methods

1 Optimal Cleaning Based on Contamination State

It ensures consistently high cleaning quality by allowing selection of the appropriate method based on the contamination state: dry cleaning for minor dirt and wet cleaning for oil-based or stubborn stains.

2 Reliable Response to Severe Contamination

It stably improves end face cleanliness, addressing contamination that was difficult to remove with conventional dry-only cleaning methods.

3 Ideal for Cleaning Multi-Fiber Connectors

It achieves uniform contact and cleaning operations for end faces of multi-fiber connectors such as MPO connectors, enabling stable cleaning that is less affected by operator skill.

(2) High Reproducibility and Efficiency through Stationary Design and Automated Cleaning Process

1 Stabilization Achieved Through Automated Cleaning Conditions

Its structure, which controls optimal contact pressure, and the automation of the cleaning process realize stable cleaning conditions independent of manual labor.

2 Reduced Variation in Cleaning Quality

Consistent results are obtained regardless of who performs the task, reducing operator dependency and contributing to the efficiency of product evaluation and inspection.

3 Improved Operational Efficiency and Reduced Process Time

The standardized cleaning process reduces rework and confirmation steps, leading to improved yield and shorter process times.

(3) Balancing Operability and Cost Efficiency by Leveraging Compatibility with Existing Products

1 Compatible with Existing NTT-AT Replacement Cartridges

Since existing, widely used NTT-AT replacement cartridges can be used as is, there is no need to switch to new consumables. The proven cleaning fabric can be used with confidence in quality.

2 Significant Increase in Cleaning Cycles Reduces Running Costs

While using the same replacement cartridges, the fabric feed length control function optimizes the efficiency of the cleaning fabric, achieving up to 6 times*1 more cleaning cycles compared to reel-type cleaners. This also contributes to reduced consumable costs.

4. Target Customers and Main Benefits

Contributes to quality uniformity, reduced operator dependency, and improved process efficiency for optical transceiver manufacturers, optical connector/cable manufacturers, inspection institutions, and others.
