Definitions

  • the present disclosure relates generally to fiber optic connection systems such as fiber optic connection systems integrated with enclosures.
  • Fiber optic communication systems are becoming prevalent in part because service providers want to deliver high bandwidth communication capabilities (e.g., data and voice) to customers.
  • Fiber optic communication systems employ a network of fiber optic cables to transmit large volumes of data and voice signals over relatively long distances.
  • Optical fiber connectors are an important part of most fiber optic communication systems. Fiber optic connectors allow two optical fibers to be quickly optically connected without requiring a splice. Fiber optic connectors can be used to optically interconnect two lengths of optical fiber. Fiber optic connectors can also be used to interconnect lengths of optical fiber to passive and active equipment.
  • a typical fiber optic connector includes a ferrule assembly supported at a distal end of a connector housing.
  • a spring is used to bias the ferrule assembly in a distal direction relative to the connector housing.
  • the ferrule functions to support an end portion of at least one optical fiber (in the case of a multi-fiber ferrule, the ends of multiple fibers are supported).
  • the ferrule has a distal end face at which a polished end of the optical fiber is located.
  • Ruggedized (i.e., hardened) fiber optic connection systems include fiber optic connectors and fiber optic adapters suitable for outside environmental use. These types of systems are typically environmentally sealed and include robust fastening arrangements suitable for withstanding relatively large pull loading and side loading.
  • Example ruggedized fiber optic connection systems are disclosed by US. Patent Nos. 7,467,896; 7,744,288; and 8,556,520. It will be appreciated that a number of different types of ruggedized fiber optic connectors are available for outside environmental use. PCT International Publication Nos.
