Abstract

Overview

IEC 61300-3-47:2014 specifies an interferometric procedure to examine and measure the end face geometry of PC/APC spherically polished ferrules or connectors. It defines how to record and compute critical geometry parameters (radius of curvature, apex offset, fibre height, end-face angle) using an optical interferometer combined with a microscope and camera. Within this standard the terms “ferrule” and “connector” are used interchangeably.

Key topics and technical requirements

Measured parameters
- Radius of curvature (domed portion of the end face)
- Apex offset (distance between ferrule axis and dome vertex)
- Fibre height (average distance between the fibre end and a fitted virtual spherical surface)
- End-face angle, tilt and key angle for angled/flat polished ferrules
Measurement system
- Interferometer (e.g., Michelson-type) producing interference fringes
- Ferrule/connector holder with axial alignment capability
- Microscope + camera with a minimum field of view of 250 µm; software for fringe analysis
Calibration and performance requirements
- XY calibration (radius of curvature) uncertainty: better than ±0.1 mm for radii 5–30 mm
- Z calibration (fibre height) uncertainty: better than ±10 nm
- Apex offset repeatability: maximum difference
