Overview
IEC 61300-3-36:2000 is an international standard published by the International Electrotechnical Commission (IEC) that specifies basic test and measurement procedures for fibre optic interconnecting devices and passive components. This part (Part 3-36) focuses on measurement methods for the inside and outside diameters of fibre optic connector ferrules. Ensuring the precision of these diameters is critical for effective optical alignment, connection quality, and overall network performance.
The standard provides detailed examination and measurement methodologies tailored to assess the precision hole diameter inside the ferrules and their external dimensions. It defines verification techniques such as pin gauging for internal diameter measurement and ring gauging, laser micrometer, and displacement methods for external diameter measurement.
Key Topics
-
Scope and Purpose: The primary goal is to standardize the measurement process of ferrule inside diameters, which are essential for fiber alignment, and outside diameters, which affect the connector fit.
-
Inside Diameter Measurement:
- Utilizes the pin gauging technique, a go/no-go calibration method for the precision hole inside the ferrule.
- Describes conditions, procedures, and tolerances ensuring reliable and repeatable measurement outcomes.
- Ensures the ferrule hole supports proper optical fiber positioning and alignment.
-
Outside Diameter Measurement:
- Describes three techniques:
- Ring gauging technique for high precision control using calibrated ring gauges.
- Laser and contact micrometer measurements offering non-contact and contact dimensional verification.
- Displacement measurement technique for reliable diameter determination based on displacement sensors.
- Details tolerances and procedures essential for connector mechanical compatibility.
-
Standardization and Compliance:
- Part of a broader series of IEC standards (IEC 61300) that govern testing and measurement of fibre optic components.
- Supports manufacturers and testing laboratories in achieving consistent, international-quality assessments.
Applications
-
