  • the disclosure relates generally to mounting features, and more particularly to mounting features for securing telecommunications components, such as optical/electrical converters, in a telecommunications terminal.
  • Fiber optic solutions have become the main part of telecommunication networks. Optical cables can transmit voice, data, and video signals over very long distances at very high speed. Because of this, developments in fiber optic telecommunication networks have consistently focused on extending the optical fiber closer to the subscriber, to the point that currently some subscribers can be connected directly to the fiber optic network through FTTx (fiber to the specific location "x") technology, including FTTH (fiber-to-the-home), which provides an "all optical" communication network to the subscribers at their homes. This dynamic subscriber bandwidth demand exists whether optical fiber reaches all the way to the subscriber or not.
  • FTTx fiber to the specific location "x”
  • FTTH fiber-to-the-home
  • the legacy infrastructure includes electrical wiring buried in trenches; for instance, wiring over which plain old telephone service (POTS) communication was provided to the subscriber.
  • POTS plain old telephone service

  • the distribution point can be any existing location where communication hardware is already present, or a new location that does not currently have any communication hardware. In either case, the distribution point may be located in an area that is much smaller than the area in a convergence cabinet. The location may be a closet inside a home or business, or on a pole or wall outside of a home or business, for example.
  • the distribution point housing in an FTTdp solution may include telecommunications components for converting optical signals into electrical signal, such as optical/electrical conversion devices.

  • This customization is time consuming and costly for manufacturers of hardware components and housings, which cost may then be passed on to the service providers and customers.
  • Similar situations may exist for hardware components and housings at other locations in a telecommunications (i.e., locations that may not be associated with FTTdp). Consequently, there is an unresolved need for a telecommunication terminal housing that can accommodate various types, sizes, and shapes of telecommunications components, such as optical/electrical conversion devices.

Abstract

Selon la présente invention, un terminal de télécommunication comprend un boîtier définissant un volume intérieur qui comprend un premier élément de montage et un second élément de montage. Le premier élément de montage comprend une première pluralité d'ouvertures de montage servant à monter un composant de télécommunication sur le boîtier. Le second élément de montage comprend une seconde pluralité d'ouvertures de montage servant à monter le composant de télécommunication sur le boîtier. Les premier et second éléments de montage sont accouplés en rotation au boîtier pour permettre le réglage de la position des première et seconde pluralités d'ouvertures de montage dans le volume intérieur du boîtier. En faisant tourner indépendamment les premier et second éléments de montage, un grand nombre de composants de télécommunication peuvent être fixés au boîtier.
