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 a covering surface adapted to cover the second opening portion, on which an extra portion of said cable is wound around an axis that is orthogonal to the covering surface; and
a moving mechanism for moving said extra-cable looping device so that it enables said second unit to insert into, or remove 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.

9. A structured shelf comprising:
-
a shelf body in which a first opening portion for insertion/removal of an access panel unit connected to a cable and a second opening portion for insertion/removal of a functional unit having a predetermined function including at least a cooling function and a power supply function are formed in a predetermined surface portion; an extra-cable looping device having a covering surface adapted to cover the second opening portion, on which an extra portion of said cable is wound around an axis that is orthogonal to the covering surface; and a moving mechanism for moving said extra-cable looping device so that it enables said functional unit to insert into, or remove from said second opening portion.

10. 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; an extra-cable looping device having a covering surface adapted to cover the second opening portion, secured to said openable/closable member for looping an extra portion of said cable thereon around an axis that is orthogonal to the covering surface in at least one position of the openable/closable member; and a moving mechanism for moving said extra-cable looping device so that it enables said second unit to insert into, or remove from said second opening portion. - View Dependent Claims (11, 12, 13, 14, 15)

16. A structured shelf comprising:
-
a shelf body in which a first opening portion for insertion and removal of a first unit connected to a cable and a second opening portion for insertion and removal of a second unit having a predetermined function are formed in a predetermined surface portion; and a door portion adapted to close and open said second opening portion with respect to a rotation axis arranged in said first opening body side, wherein an extra portion of said cable is wound on an outside of said door portion around an axis that is orthogonal to a covering surface plane of said door portion.
