摘要： A Raman amplifier having a great Raman amplification gain is disclosed. An optical transmission system 1 is provided with an optical fiber 31 for Raman amplification and an optical multiplexer 41 between a transmitter 10 and a receiver 20 in the order of enumeration, and further provided with a pump light source 51 for Raman amplification that is connected with the optical multiplexer 41. The wavelength of signal light to be transmitted from the transmitter 10 to the receiver 20 is at 1.65 &mgr;m band, and the wavelength of the pump light that is output from the light source 51 is C-band or L-band. Since the pump light for Raman amplification propagates at a low loss through the optical fiber for Raman amplification, a great Raman amplification gain can be attained by the Raman amplifier.

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： A preventive maintenance method and apparatus for a structural member in a reactor pressure vessel according to the present invention reduce a tensile residual stress on a surface of the structural member by impinging a water jet from a nozzle onto a plane surface of a deflector to thereby change direction of flow of the water jet, and impinging the water jet after being deflected onto the surface of the structural member. This method and apparatus are applicable to a narrow space portion, and can improve a residual stress on the surface of the structural member and can also prevent damage such as stress corrosion cracking.

摘要： The present invention relates to a dispersion-managed optical fiber which can be manufactured easily and has a structure which enables the easy connection thereof with other optical fiber and the like. The dispersion-managed optical fiber is a silica-based optical fiber ensuring its single mode at a predetermined wavelength within a signal wavelength band, in which first portions each having a positive chromatic dispersion and second portions each having a negative chromatic dispersion are arranged alternately and adjacent to each other. In the dispersion-managed optical fiber, the dopant concentration is made uniform in the longitudinal direction and, corresponding to the above-mentioned first and second portions, the refractive index of a glass layer not doped with GeO2 as a dopant is adjusted or the residual stresses in glass layers are changed.

摘要： The present invention relates to a WDM transmission system and the like suitable for optical communications between local stations having a relatively short repeater interval. In particular, the WDM transmission repeater employed in the WDM transmission system demultiplexes a plurality of signal lights propagating through a transmission line into first and second groups, takes out the second group, comprises a multiplexer for sending into the transmission line a new WDM signal group in which the first group thus demultiplexed and a third group of signal lights different from those of the first group are multiplexed, and has a special structure for reducing the influence of the not-demultiplexed crosstalk components within the second group upon the optical communications.
