Fiber optic connector

摘要

A connector includes a ferrule assembly having a ferrule, a hub and a spring, the ferrule having a distal face accessible at a distal end of the connector housing, the ferrule being movable in a proximal direction relative to the connector housing. The distal and proximal positions are separated by an axial displacement distance. The ferrule proximal movement is against the spring's bias. The cable of the assembly includes an optical fiber contained within a jacket and also a strength layer between the fiber and the jacket that is anchored to the connector housing. The fiber extends through a fiber from the proximal end of the connector housing to the ferrule. The fiber has a distal portion potted within the ferrule. The fiber passage has a fiber take-up region configured to take-up an excess length of the fiber corresponding to the ferrule axial displacement.

1. A fiber optic connector comprising:
a connector housing defining a distal end and a proximal end; and a fiber passage extending between the distal end and the proximal end of the connector housing, wherein the fiber passage of the fiber optic connector has a fiber take-up region that is configured to take-up an excess length of optical fiber within the fiber passage, the fiber take-up region having an intermediate section positioned between a distal section and a proximal section, the intermediate section defining an intermediate transverse cross-sectional area, the distal section defining a distal transverse cross-sectional area, and the proximal section defining a proximal transverse cross-sectional area, the distal transverse cross-sectional area and the proximal transverse cross-sectional area each being smaller than the intermediate transverse cross-sectional area, wherein the fiber passage further defines a first transition portion between the distal section and the intermediate section and a second transition portion between the proximal section and the intermediate section, each of the first and second transition portions defining a gradual increase in transverse cross-sectional area as the distal and proximal sections transition to the intermediate section so as to form funnel shaped passages at the first and second transition portions, the distal transverse cross-sectional area being defined at a location that is proximally offset from the distal end of the connector housing.
