Full title and description

STB BS EN 61300-3-27:1997 (adopted 1999) — Fibre optic interconnecting devices and passive components — Basic test and measurement procedures — Part 3-27: Examinations and measurements — Measurement method for the hole location of a multiway connector plug. This document specifies the measurement method to determine the positions of fibre holes and guide holes on the endface of multiway connector plugs to ensure correct mechanical alignment and optical performance.

Abstract

This part of the EN/IEC 61300 series defines procedures to measure the distance between guide-hole centres and the position deviation of each fibre-hole centre on multiway connector plugs used to array fibres and align pins; the measurements are intended to verify connector geometry for mechanical and optical conformity.

Scope

This standard specifies a measurement method for determining the hole locations (fibre-hole centres and guide-hole centres) on the endface of multiway connector plugs that contain multiple fibre holes and two guide holes for alignment pins; dimensions measured include the distance between guide-hole centres and the position deviation of each fibre-hole centre needed to meet mechanical and optical performance requirements.

Key topics and requirements

• Definition of measurement targets on multiway connector plug endfaces (guide-hole centre distance L and fibre-hole position deviations Pi).
• Measurement procedures and tolerancing sufficient to verify connector mechanical alignment and optical mating performance.
• Applicability to multiway connectors with multiple fibre holes and alignment-pin guide holes.
• Conformance requirements intended for use in qualification and production checking of connector geometry.

Typical use and users

Used by connector designers, manufacturing quality engineers, metrology laboratories, test houses and technicians involved in fibre‑optic connector production and inspection to verify hole locations and ensure reliable array alignment and mating. Typical applications include multi‑fibre connector qualification, production sampling and dimensional control during assembly.
