Abstract

Apparatus for arranging a plurality of stacks of optical fibre splice oganizers in a closure comprises a frame and at least two optical fibre splice organizer supports located on the frame, each organizer support being arranged to support a stack of organizers. The frame may be elongate and the organizer supports may each support a stack of organizers which extends laterally with respect to the frame. The organizer supports may be in one or more pairs, the supports of each pair being arranged back-to-back.

Claims

1. An apparatus for arranging a plurality of stacks of optical fibre splice organizers, the apparatus comprising:

a frame; and

at least two optical fibre splice organizer supports positioned on the frame, each organizer support having at least one different organizer associated therewith, wherein at least two organizer supports are arranged back to back and are located at substantially the same longitudinal position on the frame, wherein each is arranged to support a stack of organizers which extends in the opposite direction to that supported by the other organizer support, wherein the back to back organizer supports cooperate to provide at least one channel to guide at least one optical fibre positioned in at least one tube extending, in use, into a closure.

2. An apparatus according to claim 1, wherein at least part of the frame is elongate, and each organizer support is arranged to support a stack of organizers which extends laterally with respect to the frame or at least that part of the frame which is elongate.

3. An apparatus according to claim 1, wherein the at least one channel is formed, at least in part, by at least one projection provided by each organizer support, the at least one projection provided by one organizer support being longitudinally spaced from at least one projection provided by the other organizer support along the channel.

4. An apparatus according to claim 1, wherein the at least one channel is arranged to guide optical fibres which are not spliced within a closure.

5. An apparatus according to claim 1, which further comprises one or more additional organizer supports located at another longitudinal position on the frame.

6. An apparatus according to claim 5, which comprises two or more pairs of organizer supports, each pair located at a different longitudinal position on the frame.

7. An apparatus according to claim 1, wherein each organizer support is separable, in use, from the frame.

8. An apparatus according to claim 1, wherein the frame comprises a single elongate member.

9. An apparatus according to claim 1, wherein at least one of the organizer supports is provided with one or more retaining members arranged to retain one or more optical fibres, preferably in one or more tubes, which, in use, are spliced in at least one optical fibre splice organizer supported by the said organizer support.

10. An apparatus according to claim 9, wherein the or each retaining member is arranged substantially to surround the optical fibres and has a slit to allow the optical fibres to be positioned therein, wherein the slit is inclined to the direction in which the fibres extend, in use, when they are in a relaxed state.

11. An optical fibre splice closure, comprising:

(a) an apparatus according to claim 1; and

(b) a housing to enclose the apparatus.

12. A splice closure according to claim 11, wherein both the frame of the apparatus and the housing are elongate, the frame being arranged to extend longitudinally within the housing.

13. A splice closure according to claim 11, comprising a butt splice closure, the housing comprising a base, through which one or more cables may extend, and a cover for the base.

14. A splice closure according to claim 13, having sealing material received within the base of the housing.

15. A splice closure according to claim 13, wherein:

the frame is attached to, or is integral with, an attachment member which can attach the frame to a housing of an optical fibre splice closure, and

the attachment member is arranged to be attached to the housing by being trapped between the base and the cover thereof.

16. A splice closure according claim 14, wherein the sealing material is provided with means for axially compressing it, comprising two compressing portions between which the sealing material is located and means for driving the two compressing portions towards one another.

17. An apparatus according to claim 1, which additionally comprises one or more stacks of optical fibre splice organizers, the or each stack supported by an optical fibre splice organizer support.

18. An apparatus for arranging a plurality of stacks of optical fibre splice organizers, the apparatus comprising:

a frame; and

at least two optical fibre splice organizer supports positioned on the frame, each organizer support having at least one different organizer associated therewith, at least one of the organizer supports being oriented in a different direction with respect to the frame than at least one of the other organizer supports so that the at least one different organizer associated with each organizer support also has an orientation in a different direction with respect to the frame, wherein the frame is attached to, or is integral with, an attachment member which can attach the frame to a housing of an optical fibre splice closure, wherein the attachment member further comprises a cable clamp that can transmit an axial force on the cable to the housing.

19. An apparatus according to claim 18, wherein the attachment member is located substantially at one end of the frame.

20. An apparatus according to claim 18, wherein the attachment member has a first part for attachment to a cable and a second part for attachment to the housing.

21. An apparatus according to claim 18, wherein the attachment member allows substantially radial movement of the cable.

22. An apparatus according to claim 19, wherein the second part of the attachment member is arranged to cooperate with the housing substantially to prevent rotational movement of the attachment member with respect to the housing due to torsional forces on the cables.

23. An apparatus according to claim 18, wherein the frame is elongate and the attachment member extends radially from the frame.
