3D Interferometer Detection Overview

3D interferometer detection is a precise method used to test the geometry of fiber optic connector end faces. The key parameters measured include the radius of curvature (ROC) of the apex, apex offset, and fiber height. These measurements are critical for ensuring the quality and performance of fiber optic connections, as defined by the technical standards set by the International Electrotechnical Commission (IEC).

Key Parameters

1. Radius of Curvature (ROC):
   • PC Type Connector: 10~25 mm
   • APC Type Connector: 5~15 mm

   The ROC is the radius of the sphere that best fits the curvature of the fiber end face. A well-defined ROC ensures that the fiber cores make proper contact, which is crucial for minimizing signal loss.

2. Apex Offset:
   • Standard Requirement: ≤ 50 μm

   Apex offset is the distance between the highest point of the curved end face (apex) and the axis of the fiber. A large offset can lead to improper physical contact between fibers, increasing the risk of signal loss and reflection.

3. Fiber Height:
   • Standard Range: -250 nm to +250 nm

   Fiber height measures the position of the fiber end face relative to the ferrule end face. The fiber can either protrude above or be recessed below the ferrule surface. Maintaining this height within the specified range ensures optimal contact and minimizes the risk of damage or signal degradation.

Importance of Measurements

• Curvature Apex (ROC): Ensures the fiber end face has the correct shape for optimal contact, reducing signal loss and reflection.
• Apex Offset: Prevents misalignment that can cause poor physical contact and increase insertion loss.
• Fiber Height: Ensures the fiber end face is positioned correctly relative to the ferrule, preventing damage and ensuring efficient signal transmission.

Technical Standards

According to the IEC standards, the acceptable values for these parameters are crucial for maintaining the performance and reliability of fiber optic connections. Meeting these standards ensures that the fiber optic connectors will function effectively in various applications, from telecommunications to data centers.
