Laminated reel and light splitter storage case with the same laminated reel for optical transmission line excess length storage

摘要

PROBLEM TO BE SOLVED: To easily adjust lead-out lengths of individual optical transmission lines and to make the stack thickness small for compactness, when excessive lengths of the plurality of optical transmission lines are to be stored.;SOLUTION: A reel single body 32 is used which is formed by projecting an annular winding drum on the top surface of a collar plate 36 having an opening part 34 at the center part and forming a cut part 40, reaching the inner peripheral part of the collar plate 36 outside the winding drum 38 beyond the winding drum 38 from the opening part 34 of the collar plate, in the collar plate 36 and winding drum 38. A plurality of reel single bodies are stacked, having cut parts 40 shifted peripherally one after another so that vertically adjacent collar plates 36 are held at intervals large enough to put only one optical transmission line 3 therebetween. The optical transmission lines 3, which are introduced from opening parts 34 of the collar plates 36, layer by layer, are lead out to the outside of winding drums 38 through the cut parts 40 and spirally wound around the winding drums 38 and are stored.;COPYRIGHT: (C)2007,JPO&INPIT
