    摘要： 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.

    摘要： An optical transmission line having reduced flunctions in transmission quality is formed with a structure in which first and second waveguides whose transmission characteristics at a predetermined wavelength in a wavelength band in use are set opposite to each other and are arranged alternately. The chromatic dispersion of the first and second waveguides are set so as to have signs opposite to each other, and the dispersion slope of the first and second waveguides are set so as to have signs opposite to each other. Embodiments include setting the absolute value of chromatic dispersion in each first waveguide to 1 ps/nm/km or more but 10 ps/nm/km or less, and the absolute value of chromatic dispersion in each second waveguide is set to 1 ps/nm/km or more but 10 ps/nm/km or less.

    摘要： This specification describes spinal stabilization devices that may be introduced into the spine via surgical procedures. In particular, this specification describes an inter-spinous process spacer having a core chosen, in one variation, to provide a kyphotic or lordotic angle to the device. The specification also describes systems including the described devices and methods of introducing the devices and systems into the spine to provide effective stabilization.
