PURPOSE:To reduce the occupied space of an excessive length processing part in a rack to a minimum by constituting the excessive length processing part into a unit and turning this unit to make it possible that it is led out of the side face of an optical device. CONSTITUTION:An excessive length processing plate 42 is fixed vertically on the rear face of a surface plate 41 and is provided with plural optical fiber detaining members 43 to form the optical fiber excessive length processing part into a unit. One end in the lengthwise direction of the surface plate 41 is supported freely turnably on an enclosure frame of the optical device to make it possible that the excess length processing part is led out of the enclosure frame by turning. Thus, the occupied space of the excessive length processing part in the optical device is reduced to a minimum, and the efficiency of mounting of shelf units to the optical device is improved, and the optical fiber excessive length processing operation is simplified.

As an example of an optical device, one in which a plurality of shelf units each containing a plurality of printed boards are housed in a box-shaped rack in multiple stages is often used. The optical fibers (usually a plurality of fibers) introduced into the optical device are divided and wired to each shelf, and further optically connected to each printed board on each shelf. When connecting optical fibers in this way, in order to easily do so without damaging the optical fibers during device assembly or maintenance,
Optical fibers are usually of a comfortable length, i.e.
Arranged with extra length. The extra length of this optical fiber is
Due to the characteristics of the optical fiber (preventing deterioration of transmission characteristics, etc.), it is necessary to process the optical fiber by winding it into a ring shape having a diameter of at least a predetermined diameter, for example, about 100 mm or more.
