Structured shelf
First Claim
1. A structured shelf comprising:
- a shelf body in which a first opening portion for insertion/removal of a first unit connected to a cable and a second opening portion for insertion/removal of a second unit having a predetermined function are formed in a predetermined surface portion;
an extra-cable looping device on which an extra portion of said cable is wound; and
a moving mechanism for moving said extra-cable looping device to avoid a space occupied by said second unit in a state removed from said second opening portion.

Abstract
In an optical transmission node, a plurality of shelves, respectively connected to a plurality of optical cables having limitations on bending radius, are stored in one rack of the node. In a shelf body thereof, the first and second opening portions are made in a front surface, and an extra-cable looping device loops an extra portion of the optical cable, further a moving mechanism is provided for moving the extra-cable looping device to avoid a space occupied by the units in a state removed from the second opening portion, this enables extra-cable handling within a limited spatial range and the insertion/removal of the units having various functions from the shelf in a state where the cable is active and further the improvement of a shelf mounting density per rack.

11. A structured shelf comprising:
-
a shelf body in which a plurality of first opening portions each for insertion/removal of a first unit connected to a cable are formed in parallel with a desired surface portion and a second opening portion into/from which a second unit having a predetermined function is inserted/removed in a direction of intersecting with said first unit at a position adjacent to said plurality of first opening portions is formed in said surface portion;
an openable/closable member rotatable around its one side portion or one end portion attached onto a surface portion constituting a margin portion of said second opening portion closer to said first opening portions; and
an extra-cable looping device secured to said openable/closable member for looping an extra portion of said cable thereon. - View Dependent Claims (12, 13, 14, 15, 16)
