MFS, MPO 4/8/12-Fiber connectors and Fan-Out assemblies

MFS, MPO and Fan-Out INTRODUCTION

Introduction MT 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)

Introduction Factors 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 offset θ: Fiber angle s: Air gap Transverse offset is the most influential and is impacted 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

Introduction Factors affecting physical contact ➔ Whereas air gaps can be caused by following factors s: Variation of fiber height h: Insufficient fiber height q: 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 Diamond’s MT ferrule design Industry Standard MPO/MTP flat End-Face polish Diamond MPO/MFS chamfered End-Face polish PC/APC PC APC

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:  Fiber position (height)  Polishing end face angle  Surface radii  Fiber co-planarity Contamination
