A structure of a printed circuit board and a fiber storage holder for accommodating a superfluous length of fiber to be connected to a terminal on the printed circuit board. This structure if for use with the board mounted within an electronic shelf and solely accommodates superfluous lengths of fiber with pre-specified lengths. To enable removal of the printed circuit board from its shelf, free fiber is necessary. This is accommodated by a fiber storage facility which is additional to the holder. The fiber storage facility is located outside the printed circuit board receiving chamber of the shelf and is preferably attached to a shelf wall, e.g. a bottom wall, so as to store a removable length portion of fiber. Upon removal, the removable length portion provides a free fiber length which, by flexing, allows for removal from and return to the shelf of the printed circuit board. The fiber may extend between two printed circuit boards mounted in the same or separate shelves with each printed circuit board having its own fiber storage facility. It is necessary for only one of the printed circuit boards to have a fiber storage holder.
Structure de circuit imprimé et support de stockage de fibre logeant un bout excédentaire de fibre à connecter à une borne du circuit imprimé. Cette structure est conçue pour un circuit monté dans un casier électronique et ne loge que des bouts excédentaires de fibre de longueur prédéterminée. Afin de permettre de séparer le circuit imprimé de son casier, il faut un segment de fibre libre. € cette fin, le support est complété par un dispositif de stockage de fibre. Ce dispositif est situé à l'extérieur du compartiment du casier destiné au circuit imprimé. Il est de préférence fixé à une paroi du casier, au fond par exemple, et peut ainsi contenir un bout de fibre qui puisse être retiré. Lorsqu'il est retiré, ce bout de fibre constitue un bout de fibre libre dont la flexion permet de retirer le circuit imprimé du casier et de l'y remettre. La fibre peut relier deux circuits imprimés montés dans le même casier ou dans des casiers séparés, chaque circuit imprimé ayant son propre dispositif de stockage de fibre. Seul un des circuits imprimés doit être doté d'un support de stockage de fibre.
