PROBLEM TO BE SOLVED: To prevent the disconnection of optical cords occurring in the intertwining, etc., of the optical cords by arranging the optical cords extending between the connecting members disposed at a perpendicular panel and extra length reel housing parts on a straight line. SOLUTION: The extra length reel housing parts 8 are disposed at a front part tray 6 in correspondence to the connecting members 5 disposed in the upper perpendicular part 3a of the perpendicular panel 3. The extra length reel housing parts 8 are so formed that the extra length reels wound with the optical cords connected to the prescribed connecting members 5 as the extra length parts are housed into the extra length reel housing parts 8 existing right under the connecting members 5. Then, the optical cords extending between the connecting members 5 and the extra length reels housed in the extra length reel housing parts 8 are eventually arranged on the straight line. Then, the intersection of the optical cords with another optical cords is averted and the optical cords are eventually orderly arranged. The extra length reels are made freely attachable and detachable to and from the extra length reel housing parts 8. |
