    • After a wide-band DCF is wound around a bobbin to form an optical fiber coil 32, the latter is removed from the bobbin and placed into a bundle state (the state where the increase in transmission loss in the wavelength band of 1.55 &mgr;m caused by distortions in winding is reduced by 0.1 dB/km or more) released from distortions in winding. A resin 42 is used as a coil-tidying member so as to secure the optical fiber coil 32 to a storage case 40 at four positions. Both ends of the optical fiber coil 32 are connected to pigtail fibers at fusion-splicing parts 44, respectively. Even when the storage case 40 is closed with a lid after the optical fiber coil 32 is secured to the storage case 40 with the resin 42, there remain interstices within the bundle of the optical fiber coil 32 and a space between the optical fiber coil 32 and the storage case 40. As a result, even when the optical fiber coil 32 in a bundle state is accommodated in the storage case 40, transmission loss and the like would not increase.
    • 在宽带DCF缠绕在线轴上以形成光纤线圈32之后,将其从线轴上取下并放置成捆状态(由1.55μm的波长带的传输损耗的增加引起的状态 绕组失真减少了0.1 dB / km以上)。 树脂42用作线圈整理构件,以将光纤线圈32固定在四个位置处的存储盒40上。 光纤线圈32的两端分别在熔接部分44处连接到尾纤。 即使当光纤线圈32用树脂42固定在存储盒40上之后,当用盖子封闭存储盒40时,在光纤线圈32的束内仍然有空隙,并且光纤线圈32之间的空间 结果,即使束状态的光纤线圈32被容纳在收容箱40中,传输损耗等也不会增加。
