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.
