INTRODUCTION

IntroductionMT ferrule construction

➔ MT plastic multi-fiber ferrule are aligned via 2 precision guide

pins and mated trough style adapters. Physical contact of the mating surface is ensured trough integrated springs located behind the ferrule.

8-fibers MT ferrule 24-fibers MT ferrule (2 rows of 12)

IntroductionFactors affecting physical contact

➔ Standard MT ferrules can accommodate up to 24 fibers and are manufactured with tight tolerances aimed at controlling the 3 main geometric factors that impact optical performances.

d: Transverse offsetθ: Fiber angles: Air gap

Transverse offset is the most influential and isimpacted by the following:  Clearance between fiber holes and fibers Clearance between guide holes and guide pins Fiber holes and fiber core eccentricity Alignment between fiber holes axis and guide holes axis

IntroductionFactors affecting physical contact

➔ Whereas air gaps can be caused by following factors

s: Variation of fiber heighth: Insufficient fiber heightq: Incorrect end face angle

Diamond has developed a proprietary polishing process, which yields tighter tolerances on the factors impacting air gaps, resulting in:

Lower IL Higher repeatability

Introduction

What makes Diamond’s MT ferrule design better

Here is why Diamond can offer a 1000 Mate De-Mate life cycle for the MPO and a 500 for the MFS connectors.

➔ Physical contact ensured because of smaller contact end face➔ Reduced sensitivity to contamination / Easy cleaning process➔ 100 % interferometer measurement of relevant surface

parameters:
