The 1.0 mm inner bore is designed for 125 μm cladding fiber, while the 1.4 mm outer diameter ensures compatibility with standard ferrule sleeves and connector bodies.

This geometry provides:

• Stable fiber centering

• Low eccentricity

• Excellent mating repeatability

• Compatibility with most telecom connector housings

It is the reason this ferrule format has become an industry standard for single-fiber connectors.

Key dimensional design

This structure allows the ferrule to support PC, UPC, and APC polishing types depending on the connector design.

Optical and mechanical performance targets

These values are critical for maintaining low insertion loss and stable return loss over the lifetime of the connector.

Why zirconia ceramic is used

Zirconia ceramic is not chosen by accident.
It offers:

• Extremely high hardness

• Low thermal expansion

• Excellent surface polishability

• Long-term dimensional stability

This ensures that once the fiber is aligned and polished, it stays aligned — even after thousands of insertions.

Where this ferrule is used

The 1.0 × 1.4 mm ferrule is commonly found in:

• FC fiber optic connectors

• SC and ST connectors

• Fiber optic pigtails

• Patch cords

• FTTH and telecom equipment

• Optical test cables

It is a core component behind almost every single-fiber optical connector in modern networks.

Professional Q&A

Q1: Can this ferrule be used for APC connectors?
Yes. The same 1.0 × 1.4 mm ferrule can be used for PC, UPC, or APC polishing. The difference comes from the end-face angle and polishing process, not the ferrule size.

Q2: Why is concentricity so important?
Because the fiber core is only about 9 microns wide. If the ferrule bore is off-center, the fiber cores will not align when two connectors mate, increasing insertion loss and reflection.

Q3: Is this ferrule compatible with automated polishing?
Yes. This ferrule size is designed for standard polishing fixtures and automatic fiber polishing machines, making it suitable for mass production.

In FTTH production lines, the connector itself is only half the story.
