を結束すれば整然と保管を行うことができるが、
結束作業は手数がかかる欠点がある。 In this case, the extra length was simply rolled up into a loop and inserted into the extra length storage tool, so the loops tend to get disordered and come apart inside the extra length storage tool, making it impossible to store them in an orderly manner. It was hot. You can store it neatly by tying the extra length of the loop, but
The tying work has the disadvantage of being time-consuming.

As shown in FIG. 1, the optical fiber surplus length holding sheet 1 of this embodiment includes a sheet main body 2 made of polyester or the like, and a holding piece forming a pair of holding pieces 3 and 4 is formed on the sheet main body 2. Slits 5,
6 are provided facing each other in opposite directions.
These holding piece forming slits 5 and 6 are holding piece contour forming slit portions 5 which are formed without forming a closed loop in order to form the holding pieces 3 and 4 supported in a cantilever manner.
a, 6a, and these holding piece contour forming slit portions 5
The extension slit portions 5b and 6b are connected to both ends of the slits 5a and 6a, respectively, with their directions facing outward. Round holes 7, 8 are formed at the ends of each extended slit portion 5b, 6b to facilitate the rising of the holding pieces 3, 4 and to prevent the slits 5, 6 from expanding. A metal connecting portion holder 9 is fixed on the seat body 2 adjacent to one of the holding pieces 4 with adhesive or a grommet.

い上非常に便利である。(Effects of the Invention) As explained above, in the optical fiber surplus length holding sheet according to the present invention, the holding piece forming slits forming the holding pieces in the sheet body form a closed loop to form the holding pieces with cantilever support. It consists of a retaining piece contour forming slit portion which is formed without the retaining piece contour, and extension slit portions which are connected to both ends of the retaining piece contour forming slit portion with their directions facing outward. The presence of the extended slit portion makes it possible to weaken the holding force of the extra length of the optical fiber core between the holding piece and the sheet body. For this reason,
Even if the extra length of the optical fiber is held by the extra length holding sheet, it is possible to prevent an increase in transmission loss of the optical fiber. Further, since this extra length holding sheet can be formed simply by punching out the sheet, it is available at a very low cost, is not bulky, and is very convenient to handle.
