Definitions

  • the present disclosure relates generally to fiber optic assemblies and more particularly to covers for protecting and cleaning an end face of a fiber optic connector.
  • Fiber optic connectors typically include a ferrule that surrounds and supports an optical fiber on an end face of the connector.
  • the optical fiber is finely polished to provide a clean and clear interface with an adjoining optical fiber supported by mating component within an adapter that receives the connector.
  • Small scratches e.g., on the order of micrometers
  • dust particles can greatly impact the performance of the connector. Accordingly, connectors are often transported and stored with dust caps/covers that are designed to shield the end face.
  • a connector Even with a dust cap, a connector may still become contaminated with particulates. Particles from the interior of the dust cap may migrate to the end face of the connector, especially when the connectors are being transported, presumably due to movement of the connectors and corresponding air currents mobilizing the particles. Additionally, micro- passages may facilitate communication of very small particles to the end face of the connector even when the dust cap is installed. Such passages may be inherently present due to limits of tolerances in the dimensions of the connector bodies and dust caps.
  • the dust caps may be temporarily removed prior to the connectors being used in operation, thereby exposing the end faces to particles before the dust caps are placed back on the connectors.
  • the cable assembly may be tested to verify its operation and check its performance before the fiber optic network is operational.
  • the testing involves removing the dust caps to connect test equipment to the connectors.
  • the test equipment is eventually disconnected, at which point the dust caps may be replaced if mating components for the connectors are not yet installed and/or not yet ready to be optically coupled to the connectors.
  • there are periods of time during such testing where the end faces of the connectors are left exposed and unprotected by the dust caps.

  • the connector includes a ferrule that defines an end face of the connector.
  • the optical fiber extends through the ferrule to the end face of the connector, and an end of the optical fiber is polished proximate to the end face.
  • the cover in this embodiment which is also received over the end face of the connector, includes a body and a particle collection layer coupled to the body so as to overlay the end face of the connector and the polished end of the optical fiber.
  • the particle collection layer may comprise, for example, a spray-on adhesive, an adhesive tape, a polymer film, or any other layer configured to draw loose particulates of dust and/or debris from the end face of the connector upon removal of the cover from the connector.

  • the particle collection layer is positioned within the cavity.
  • the body of the cover may have a shape corresponding to a receptacle of an adapter that is configured to receive the ferrule.

Abstract

L'invention porte sur un ensemble fibre optique qui comprend un connecteur, une fibre optique et un capuchon. Le connecteur comprend une ferrule qui délimite une face terminale du connecteur. La fibre optique s'étend à travers la ferrule jusqu'à la face terminale du connecteur et une extrémité de la fibre optique est polie à proximité de la face terminale. Le capuchon, qui est reçu au-dessus de la face terminale du connecteur, comprend un corps et une couche collectrice de particules qui est couplée au corps de façon qu'elle recouvre la face terminale et l'extrémité polie de la fibre optique. La couche collectrice de particules est conçue pour enlever les particules de poussière et/ou débris lâches présents sur la face terminale du connecteur lorsque le capuchon est retiré du connecteur.
