Definitions

  • the described technology generally relates to components for connecting data transmission elements and, more specifically, to adapters configured to connect different types of fiber optic connectors and connector assemblies configured to facilitate optimized performance of the connection formed within the adapters.
  • An optical fiber connector is a mechanical device disposed at an end of an optical fiber that acts as a connector of optical paths, for example, when optical fibers are joined together.
  • An optical fiber connector may be coupled with an adapter to connect an optical fiber cable to other optical fiber cables or devices.
  • An adapter may generally include a housing having at least one port that is configured to receive and hold a connector to facilitate the optical connection of one connector to another connector or device.
  • an LC adapter is typically configured to receive one or more standard sized LC connectors.
  • Hybrid adapters are configured to join different types of optical fiber connectors.
  • At least one disadvantage of traditional hybrid adapters is that they are configured to couple two full size connectors causing the adapter ends to be bulky and, therefore, to take up too much space on both sides of the adapter. This is a major shortcoming in most hybrid adapter applications where when one end of the adapter is intended to be disposed inside a small module, as both the corresponding adapter end and the connector occupy too much space within the module.
  • Certain conventional hybrid adapters have been designed to accommodate coupling a standard full size optical fiber connector with a simplified optical fiber connector.
  • a simplified optical fiber connector is merely a ferrule that may or may not have a metallic flange assembled onto the ferrule used to terminate the end of an optical fiber.
  • the simplified connector is held rigidly inside the adapter.
  • both ferrules in a mated pair should be floating, and subject to spring pressures that push the end faces of a pair of mated ferrules together.
  • a simplified optical fiber connector may not include a spring behind the ferrule.
  • the simplified optical fiber ferrule will be held rigidly inside one end of the adapter and the connection formed by the hybrid adapter will be subject to degraded performance.
  • an optical fiber connection assembly may include a hybrid adapter and at least one first optical fiber connector.
  • the hybrid adapter may include a first adapter end configured to be coupled to a first connector type, a second adapter end configured to be coupled to a second connector type that is different from the first connector type, and at least one mating component arranged on the first adapter end.

This is a drawback, for example, when one end of the adapter is intended to be disposed inside a small module, as both the corresponding adapter end and the connector will occupy too much space within the module. Therefore, in lieu of coupling to two full size connectors, some adapters have been designed to accommodate coupling a standard full size optical fiber connector with a simplified optical fiber connector or two simplified optical fiber connectors.
  • a simplified optical fiber connector is merely a ferrule that may or may not have a metallic flange assembled onto the ferrule and which is used to terminate the end of an optical fiber.
  • U.S. Patent No. 5,719,977 titled "Optical Connector with Immovable Ferrule” discloses an adapter configured to couple to a standard size connector at one end and a simplified optical fiber connector at the other end.
  • a disadvantage of such a hybrid adapter is that the simplified connector is held rigidly inside the adapter.

  • the adapter of FIGS. 2A and 2B is not a hybrid adapter and is designed for mounting directly on a circuit board rather than coupling an external optical fiber connector to a connector disposed within a module.
  • optical fiber is intended to apply to all types of single mode and multi-mode light waveguides, including one or more bare optical fibers, coated optical fibers, loose-tube optical fibers, tight-buffered optical fibers, ribbonized optical fibers, bend performance optical fibers, bend insensitive optical fibers, nanostructured optical fibers or any other expedient for transmitting light signals.

Abstract

L'invention concerne de manière générale des ensembles de connexion de fibre optique qui peuvent comprendre des ensembles adaptateur et connecteur hybrides. L'adaptateur hybride peut être configuré pour raccorder un premier type de connecteur et un second type de connecteur, le premier type de connecteur étant différent du second type de connecteur. Par exemple, le premier type de connecteur peut être un micro-connecteur et le second connecteur peut être un connecteur LC. Un ensemble connecteur peut être configuré comme un micro connecteur ayant un élément de tension configuré pour faciliter une performance optique optimisée en chargeant par ressort les ferrules tout en conservant un faible facteur de forme.
