Definitions

  • the present invention generally relates to a fiber optic splice tray for telecommunication cables wherein the splice tray provides environmental protection to the optical connections made therein.
  • the exemplary tray can be used in aerial telecommunication enclosures to protect optical connection interfaces.
  • Telecommunication cables are ubiquitous and used for distributing all manner of data across vast networks.
  • the majority of telecommunication cables are electrically conductive cables
  • the use of optical fiber cables is growing rapidly as larger and larger amounts of data are transmitted.
  • telecommunication cables are routed across networks, it is necessary to periodically open the cable and splice or tap into the cable so that data may be distributed to "branches" of the network.
  • the branches may be further distributed until the network reaches individual homes, businesses, offices, and so on.
  • the distributed lines are often referred to as drop lines or distribution lines.
  • the enclosure allows easy and repeated access to the cable, such that technicians may easily access the cable to provide any necessary services.
  • Enclosures can be located either underground or suspended aerially from telecommunication distribution cables. Because aerial enclosures are suspended from a telecommunication cable, they need to be as small and light weight as possible for the given capacity. In order to accomplish this, the level of environmental protection provided by an aerial telecommunication enclosure has been reduced in some styles of telecommunication enclosures such as free breathing enclosures.
  • optical fibers and their connections are sensitive to their physical handling and the presence of debris such as dust, moisture, and the like. This sensitivity of optical fibers and their connection devices increases the likelihood of damaging the fibers or the connection devices, such as during reentry into the enclosure when connecting a drop line or the like.
