Definitions

  • This invention relates to optical fibre management and in particular concerns a method and apparatus for fibre management in the context of fibre to the home/premises applications (FTT/H/P/X), hereinafter referred to as FTTH.
  • FTT/H/P/X home/premises applications
  • Fibre to the home concerns the installation of optical fibres in the subscriber loop of telecommunications networks either instead of or to replace twisted copper pairs.
  • DSL Broadband which utilises existing copper pairs
  • FTTH is on average ten times faster than DSL Broadband and is inherently non- asymmetric in the sense that FTTH network connections operate at substantially the same speed in both directions.
  • Emerging high speed services such as high definition IPTV and the like are driving the requirement for higher speed access and consequently FTTH is emerging as the preferred high speed access technology, particularly for new homes and business premises where there is no existing network infrastructure.
  • apparatus for optical fibre management comprising an annular optical fibre organiser for storing length(s) of fibre, and an organiser mounting member, the organiser being removably mountable on the said mounting member without use of threaded fasteners and being rotatably adjustable on the mounting member.
  • This rotational adjustment of the annular organiser position on the mounting member permits coiling and uncoiling of fibre stored on the organiser to adjust the degree of looseness or tightness of the fibre thereon in order to accommodate thermal expansion and contraction which could otherwise damage the fibre.
  • the rotational adjustment also enables the end(s) of the outgoing fibre(s) to be moved to a pre-determined angular position on the said mounting member, for convenient subsequent access to the end(s) to be connectorised and/or to position the connectorised end(s) in connector holding means associated with the organiser.
  • the rotatably adjustable fibre organiser provides a robust and convenient means for handling fibre overlength when a fixed outlet (connector) position exists, since the installation engineer can readily manipulate the organiser to rotate it on the mounting member, which may be part of an organiser tray, fibre cabinet, fibre distribution frame or the like. For example, it may be desirable to rotate the organiser so that a fibre connector when installed is correctly orientated to face in a particular direction, for instance downwards towards a floor so that any stray laser light escaping from the connector may be also directed downwards in a harmless manner.
  • the organiser may comprise at least one holder for receiving an optical component, fibre connector, cable splice or the like connected at the end of a respective fibre stored on the said organiser, and wherein said angular position of said connector is adjustable with respect to said mounting member by rotation of said organiser.
  • said organiser comprises at least one optical fibre guide for fibre storage, the said fibre guide having minimum bend control radius, the rotational centre of which is substantially coincident with the axis of rotation of the said organiser on the said mounting member.
  • This enables convenient handling of the fibre in the sense that rotation of the organiser about its axis of rotation results in uncoiling of the fibre on the fibre guide as uncoiling occurs about the rotational centre of the guide which is coincident with the rotation axis.
  • references herein to the "annular" organiser relate to substantially circular organiser shapes, at least with regard to the fibre-guiding surface and the inner perimeter of the organiser.
  • the outer perimeter of the organiser could be made in other shapes such as square or oval, if these can be accommodated while allowing the organiser to be rotated in use.
  • the organiser preferably has an annular centre and an annular outer circumference, and an inner annular circumference which is closer to the outer annular circumference than to the annular centre. More preferably, the organiser has a central aperture extending from its annular centre of rotation to its inner annular circumference; however the central aperture may be partially covered or partially closed.
  • the mounting member may be arranged to contact the inner annular circumference of the organiser when mounted on the mounting member.
  • a preferred form of mounting member comprises a substantially circular formation which fits closely within the said central aperture of the organiser.
  • the mounting member may include a formation, preferably a substantially circular formation, which fits closely around the outer annular circumference of the organiser when mounted on the mounting member.
  • the mounting member may have other forms, for example an array of upstanding posts or pillars which contact the inner and/or outer annular circumference of the organiser.
  • the wall plug housing preferably comprises a wall box insert for location in a wall/floor or ceiling cavity recess, with the organiser located between an open end of the wall box insert and the cover.
  • the wall box insert is preferably of the type used for household electrical cable management comprising an open metal or plastics box having one or more apertures for incoming and/or outgoing cables capable of being secured within the cavity with screws or the like.
  • the wall plug housing further comprises a faceplate detachably attachable to the open end of the wall box insert.
  • a domestic plug socket is provided with a faceplate, which when in combination with a wall box insert is mounted flush with the surface of a wall
  • embodiments of the present invention also contemplate similar arrangement such that the faceplate may be removably attached to the wall box insert, and hence wall, by screws or the like.
  • the organiser is disposed between the faceplate and the cover.
  • the organiser containing the over length fibre is located on the wall rather than in the wall by virtue of the fact that it is positioned between the faceplate and the cover. This is particularly advantageous since is separates the incoming fibre, in the wall insert box, from the main fibre management part of the wall plug to enable easier manipulation of the fibre in use.
  • the organiser is preferably detachably attachable to the faceplate so that it and its contents, including the over length fibre, may be removed from the faceplate and hence the main structure of the wall plug box for manipulation of the fibre at a remote location from the wall mounted components of the wall plug. Additionally or alternatively the organiser may be pivotally mounted with respect to the faceplate, for example in one embodiment the organiser is carried by a cover or lid hinged to the faceplate, preferably along one side of the faceplate, to provide ready access to the over length fibre within the organiser.
  • the present invention also contemplates embodiments where the organiser is rotatable on, or with respect to, the faceplate.
  • rotation of the organiser on the faceplate can be used to correctly position the organiser rotationally with respect to the faceplate, for example to align a fibre connector or the like with respect to the fixed faceplate and hence the wall plug as a whole.
  • the organiser comprises a ring shaped body having a minimum bend control radius in the form of a fibre guide on an outer circumference thereof.
  • the ring can be rotated to manipulate the angular position of the ring shaped organiser on or with respect to the faceplate.
  • the ring shaped organiser readily enables the over length fibre to be unwound and rewound on the organiser when the fibre is manipulated by the installation engineer.
  • the faceplate comprises at least one aperture, preferably a plurality of apertures and most preferably a plurality of apertures including a central aperture for observation of the incoming fibre in the wall insert box.
  • at least one aperture is provided which is of sufficient size to enable the installation engineer to observe the positioning and condition of the incoming fibre in the wall box when the faceplate is attached to the wall box insert during installation procedures. This enables the installation engineer to observe and possibly prevent damage to the incoming fibre when manipulating the over length fibre externally of the wall insert box.
  • the central aperture is circular and comprises an upstanding cylindrical projection which provides a connection means for attaching the rotatable ring shaped body of the organiser to the faceplate.
  • the organiser comprises at least one fibre connector holder for removable attachment of a respective fibre connector to the organiser. In this way the connector attached to the over length fibre can be held on the organiser to secure the connector to the wall plug.
  • the optical fibre connector holder is arranged so that the connector is attachable to the organiser at an angle with respect to the plane of the organiser. The angled holder provides for safe installation of the connector so that any stray laser light emitted from the fibre or connector in the installed wall plug will be directed at an oblique angle with respect to the plane of the wall on which the wall plug is mounted.
  • the organiser further comprises at least one copper wire connector holder for receiving at least one copper wire connector for removable attachment to the wall plug.
  • the wall plug of the present invention also contemplates embodiments where the wall plug provides the same functionality as a conventional telecommunications wall plug for copper connectivity, for example for DSL connections.
  • the wall plug therefore contemplates hybrid embodiments where it can be used for both fibre and copper network connections. This is particularly useful where wall plugs of the present invention are installed in homes or small business premises which have the option of both copper and fibre connectivity on the local loop so that the customer, i.e. subscriber, has the option of copper (DSL) or fibre connection according to the tariffs available from their service provider. For example, a subscriber may elect to be connected to the local loop initially on a less expensive but slower copper connection but have the option available to switch to a higher access speed fibre connection at a later date without incurring the full cost of a new FTTH connection.
