Abstract
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.
