Definitions

  • the present invention relates to optical fibre communications, and in particular to an optical fibre patch panel assembly suitable for a closure, a cabinet, a sub-rack or other container.
  • a patch panel is a support on which optical fibre connectors may be mounted.
  • Patch panels are commonly used in optical fibre closures, optical fibre cabinets, and optical fibre distribution racks, for example.
  • the optical fibres which are interconnected by means of the optical fibre connectors are normally contained in protective outer jackets.
  • Such optical fibres may, for example, be pigtails, patch cords, jumpers etc.
  • a first aspect of the present invention provides an optical fibre patch panel assembly, comprising:
  • a patch panel comprising a plurality of connector securement means, by means of each of which an optical fibre connector may be secured to the patch panel;
  • each optical fibre guide means includes at least one attachment means, by which the guide means may be removably attached directly or indirectly to the patch panel and/or the base by being moved towards the base in a direction substantially perpendicular thereto.
  • the assembly according to the invention has the advantage that the or each optical fibre guide means may be attached after the optical fibre connectors have been secured to the patch panel. This provides greater access to the patch panel compared to systems in which the guide means are permanently in place, and thus enables the connectors to be attached to the patch panel more easily and with less chance of damage to the optical fibres and the connectors. Also, because the guide means may be attached by being moved in a direction substantially perpendicular to the base, the guide means may be passed between the optical fibres extending from the patch panel without significantly disturbing the optical fibres (and thus without damaging the fibres or causing transient signal losses in the fibres).
  • the attachment means of the or each optical fibre guide means comprises at least one groove and/or projection which, in use, may engage at least one corresponding projection and/or groove (respectively) on the patch panel, to permit the optical fibre guide means to be slid onto the patch panel.
  • the base may include at least one fastening means which may cooperate with an attachment means of the or each optical fibre guide means to attach the guide means to the base.
  • the cooperating attachment means and fastening means may, for example, be interlocking, e.g. snap-fit, parts.
  • the or each fastening means preferably comprises at least on slot, and the or each attachment means preferably comprises at least one resilient detent.
  • the or each fastening means may advantageously comprise part of a plate which, at least in use, is attached to a main part of the base. The plate may be attached to the main part of the base by means of screws, bolts, snap-fit parts etc, for example.
  • a plurality of optical fibre guide means may be joined together, preferably at or near their ends furthest from the base.
  • the optical fibre guide means are preferably joined together by means of at least one joining member, which joining member preferably includes one or more attachment means which, in use, attach(es) the joining member directly to the patch panel.
  • the or each guide means is preferably in the form of at least one curved plate, or the like.
  • the or each guide means preferably guides the optical f ⁇ bre(s) extending from the patch panel in a controlled bend which does not violate the critical bend radius of the optical fibre(s).
  • the guide means advantageously provide protection to the optical fibres immediately adjacent to the patch panel.
  • the invention provides a container, preferably an optical fibre closure or cabinet, including an optical fibre patch panel assembly according to the first aspect of the invention.
  • FIG 1 shows one type of patch panel assembly according to the invention
  • Figure 2 shows a base plate of another type of patch panel assembly according to the invention
  • Figure 3 shows an optical fibre guide means for attachment to the base plate of Figure 2;
  • Figure 4 shows another type of optical fibre guide means of an assembly according to the invention
  • FIG. 5 shows an assembled patch panel assembly of the type shown in figures 2 and 3;
  • FIGs 6 and 7 show an assembled patch panel assembly including an optical fibre guide means of the type shown in Figure 4.
  • FIG. 1 shows a patch panel 1 , with optical fibre connector securement sockets 2, and optical fibre guide means 3 of a patch panel assembly according to the invention.
  • Each guide means 3 has the form of a curved plate, and has a projection 5 which can slide into a respective slot 7 in the patch panel.
  • Figure 2 shows a plate 9 of another type of patch panel assembly, which, in use, is attached to a main part of the base.
  • the plate 9 includes three slots 10 for receiving three guide means.
  • a suitable guide means 1 1 is shown in Figure 3.
  • the guide means 1 1 has resilient detents 13 which arranged to interlock with a slot 10 in the plate 9, thereby securing the guide means 1 1 to the base.
  • Figure 4 shows optical fibre guide means 15 of another type of patch panel assembly according to the invention.
  • the joining member has attachment means 18, in the form of projections 19, to attach it directly to a patch panel.
  • FIG. 5 shows a patch panel assembly of the type illustrated in figures 2 and 3 assembled in an optical fibre cabinet 20.
  • the base 21 of the cabinet 20 comprises the main part of the base of the assembly, to which the base plate 9 is attached.
  • An optical fibre pigtail 23 is shown, its optical fibre connector 24 mounted on the patch panel 25.
  • FIGs 6 and 7 show views of another patch panel assembly according to the invention, assembled in an optical fibre cabinet 20.
  • This patch panel assembly includes guide means 15 of the type shown in Figure 4, i.e. with a joining member 17 joining the guide means.
  • the joining member is attached to the patch panel 25 by joining means 18.

Abstract

L'invention porte sur un ensemble panneau de raccordement de fibres optiques comprenant (a) un panneau de raccordement (25) comportant une pluralité d'éléments de fixation de connecteurs, chacun d'eux permettant de fixer un connecteur (25) de fibres optiques au panneau de raccordement; (b) un ou plusieurs guides de fibres optiques qui, en utilisation, guide(nt) une ou plusieurs fibres optiques (23) s'étendant à partir du panneau de raccordement, et (c) une base généralement plate sur laquelle est placé, au moins en utilisation, le panneau de raccordement. Cette invention se caractérise par le fait que chaque guide de fibres optiques comprend au moins un élément de fixation au moyen duquel le guide peut être fixé amovible directement ou indirectement au panneau de raccordement (25) et/ou à la base (9) lorsqu'il est déplacé vers la base dans un sens pratiquement perpendiculaire à celle-ci.
