Abstract
(EN)
An optical ferrule (200) has opposing major top (10) and bottom (20) surfaces where the bottom surface includes discrete spaced apart first (90) and second (100) platforms arranged along a mating direction of the optical ferrule (200). During a mating of the ferrule (200) with a mating optical ferrule (200'), the first (90) and second (100) platforms of the ferrule (200) slide against corresponding respective first (90') and second (100') platforms of the mating ferrule (200'). Upon full mating of the ferrule (200) with the mating ferrule (200'), the second platforms (100, 100') of the ferrule and the mating ferrule remain in contact with and rest on each other, and the first platform (90, 90') of neither ferrule makes contact with the other ferrule.

Ferrule optique (200) comportant des surfaces supérieure (10) et inférieure (20) principales opposées, la surface inférieure comprenant des première (90) et seconde (100) plateformes espacées distinctes disposées le long d'une direction d'accouplement de la ferrule optique (200). Pendant un accouplement de la ferrule (200) avec une ferrule optique d'accouplement (200'), les première (90) et seconde (100) plateformes de la ferrule (200) glissent contre des première (90') et seconde (100') plateformes respectives correspondantes de la ferrule d'accouplement (200'). Lors d'un accouplement complet de la ferrule (200) avec la ferrule d'accouplement (200'), les secondes (100, 100') plateformes de la ferrule et de la ferrule d'accouplement restent en contact et reposent l'une sur l'autre, et la première (90, 90') plateforme d'aucune ferrule n'entre en contact avec l'autre ferrule.
