ST Hand Polishing Disc

Overview

The ST Hand Polishing Disc, commonly referred to as a "hockey puck," is an essential tool for technicians manually polishing fiber optic connectors. It ensures precise alignment and consistent end face geometry, which is critical for achieving high-quality optical connections in field or laboratory environments.

This polishing disc is engineered to hold the connector ferrule at the exact required angle against the polishing film. By maintaining this orientation, it prevents uneven surface finishes, helping to ensure that terminated connectors meet strict signal transmission standards.

Key Features

• Precision Machining
  Manufactured to close tolerances to ensure the ferrule maintains the correct angle during the polishing process.
• Consistent Results
  Promotes repeatable, high-quality fiber end face finishes across multiple terminations.
• Durable Construction
  Designed for frequent handling in diverse environments, from technician toolkits to repair shops.
• Ergonomic Design
  The "puck" form factor allows for comfortable grip and controlled pressure application during manual polishing.
• Simplified Termination
  Assists in reducing human error during the hand-polishing phase of connector assembly.

Applications

• Field termination of ST fiber optic connectors
• Optical connector repair and maintenance
• Fiber optic laboratory and educational training
• Prototyping of fiber optic cable assemblies

Frequently Asked Questions

What is the purpose of a hand polishing disc?
The disc holds the fiber optic connector ferrule at a precise, fixed angle, ensuring the end face is polished evenly and correctly against the polishing film.

Is this disc compatible with other connector types?
No, this specific model is designed for ST connectors only.

Why is the polishing disc sometimes called a "hockey puck"?
The term is a common industry nickname derived from the disc's shape and size, which resembles a standard ice hockey puck.

Can this be used for machine polishing?
No, this tool is designed specifically for manual hand polishing applications.

How do I ensure a good polish?
Always use the appropriate grit polishing films in the correct sequence while using the disc to maintain consistent pressure and alignment.
