Abstract: An optical fibre distribution system, comprising: (a) at least one stack of optical fibre interconnection modules; and (b) at least one optical fibre storage region located in at least one said stack of interconnection modules, which storage region, in use, stores spare lengths of one or more optical fibres which extend between respective interconnection modules, wherein the or each storage region comprises a plurality of supports which are mutually spaced-apart across at least part of the width of the stack of interconnection modules such that, in use, each spare length of optical fibre may be routed into the storage region and routed around at least one of the supports which may be selected to provide at least approximately the correct storage length required for that spare length of optical fibre.

Abstract: A wraparound sleeve has closure members, typically in the form of upstanding rails, at its longitudinal edges. A channel having a discontinuity along its length is positioned over the closure members to hold the sleeve in a closed configuration. A clip is positioned between the closure members and the channel to bridge the discontinuity in the channel.The discontinuity in the channel preferably extends through the channel entirely, so that the channel is in two or more parts, which can be installed end to end.The discontinuity in the channel aids installation, particularly where the closure to be formed is of long length.This application is a continuation of application Ser. No. 920,493, filed Oct. 17, 1986, now abandoned, which is a continuation of application Ser. No. 071,536, filed July 9, 1987, now abandoned.
