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 μm 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： The present invention relates to an optical fiber or the like which allows more precise compensation for the chromatic dispersion of a transmission optical fiber over a broad wavelength band. The optical fiber has a chromatic dispersion of −100 ps/nm/km or less in a wavelength band of 1535 to 1565 nm, 1565 to 1610 nm, 1554 to 1608 nm or 1535 to 1610 nm. In particular, the chromatic dispersion profile of the fundamental mode of this optical fiber defined by the orthogonal coordinate system of the wavelength and chromatic dispersion value has a shape such that, over the entire wavelength band except for the shortest and longest wavelengths thereof, the chromatic dispersion values on the chromatic dispersion profile are respectively located on the minus side of the associated chromatic dispersion values on a straight line connecting the chromatic dispersion values at the shortest and longest wavelength. Since the chromatic dispersion profile of the transmission optical fiber such as a conventional single-mode fiber or the like has a shape opposite to that of this optical fiber, the chromatic dispersion of the transmission optical fiber can be compensated for more precisely by using this optical fiber as a dispersion compensating optical fiber.

摘要： A dispersion compensating fiber 1 is placed in the form of a coil or bundle within a housing 2, and a filling material 3 having a viscosity of 0.01 Pa·s to 0.6 Pa·s at normal temperature before curing is filled in a space around the dispersion compensating fiber 1 within the housing 2 and then the filling material is cured. As a result, a change of transmission loss caused by a temperature variation due to heat cycles of the dispersion compensator can be reduced. A difference in transmission loss can be further reduced by employing a method of placing the dispersion compensating fiber in the housing in the form of a loosely wound bundle and then pouring the filling material, or a method of applying vibration to the housing, in which the dispersion compensating fiber is placed, when pouring the filling material.

摘要： An optical fiber coil of the present invention includes an optical fiber, a storing case which stores the coiled optical fiber therein, and a filler in the storing case. The filler directly comes into contact with the glass portion of the optical fiber or contact with a thin film coating of not more than 1 &mgr;m being formed on a surface of the glass portion and having a hydrogen intrusion suppressing function. According to the optical fiber coil of the present invention, since the filler directly comes into contact with the glass portion of the optical fiber, the microbend loss can be further suppressed and the transmission can be stable.

摘要： An image pickup lens unit, in which a holder body and a cover can be easily connected together, without additional components and a resin flow path for the connection. A lens 10 is positioned in a first holder member 20 which remains in a mold. A second holder member 30 for preventing the lens 10 from falling off is molded such that it is welded to the first holder member having the lens 10 positioned therein. This facilitates molding of the second holder member 30 and joining of the second holder member 30 to the first holder member 20 at the same time. Since there is no need to provide a resin flow path for joining the first holder member 20 and the second holder member 30 together, the image pickup lens unit can be made small in size.
