摘要： An electrical variable optical attenuator (10) of the present invention has a housing (1), a cover (2), an attenuating means (3), an optical module (4), an electrical driving element (5), an input fiber (87) and an output fiber (86). The attenuating means includes a carrier (30) having a guide groove (301) and an inner screw (302). A filter (32) is fixed on the carrier. The optical module includes a guide pole (41). The electrical driving element has a screw rod (552), which couples with the inner screw. The attenuating means is assembled inside the optical module with the guide pole being received in the guide groove to confine the direction of movement of the carrier along the screw rod, thus helping to avoid trembling of the filter when the screw rod is rotated.

摘要： A gas blocking device is used in an optical fiber repeater or other device to prevent the passage of gas, for example, to prevent nitrogen from escaping from a pressurized housing through a fiber holding tube or pigtail. The gas blocking device includes a fiber containing body, a fiber organizing insert, and a locking member securing the insert to one end of the body. The fiber containing body is attached to one end of the fiber holding tube. The fibers extend from the fiber holding tube through a passageway in the body, and each of the fibers extends through a fiber receiving hole in the fiber organizing insert. The insert engages the body such that the insert is prevented from rotating with respect to the body and the fibers are protected against microbending and other damage. A material, such as hot melt glue, fills at least a portion of the body and surrounds the fibers to block the gas from entering the fiber holding tube.

摘要： The invention provides a planar lightwave circuit type variable optical attenuator in which a small PDL is maintained even when an attenuation is large. The variable optical attenuator is constituted by a Mach-Zehnder interferometer comprising a substrate, two optical waveguide arms buried in a clad formed on the substrate, and thin-film heaters disposed on the surface of the clad and adjusting optical lengths of the optical waveguide arms. The optical waveguide arms are each made of a silica-based glass material, and a difference &Dgr;L0 between arm lengths is set to be in the range of 0.38 &mgr;m to 0.52 &mgr;m.

摘要： A storage tray arrangement for storing cable slack in fiber optic systems includes a vertically oriented frame and at least one tray mounted to the frame in a vertical plane parallel to the frame. There is a mounting construction that permits the tray to be pivotally secured to the frame. The mounting construction permits the tray to be selectively pivoted relative to the frame within the vertical plane. In preferred arrangements, the trays are mounted as tray sets having at least two trays mounted to a common pivot post. Particular preferred trays include trays having scalloped side walls. Methods for storing cable slack utilize trays and mounting arrangements as described herein.

摘要： A broadband optical spectrum generating apparatus 20 includes an ultra-short pulse fiber laser 22 that generates pulsed light having a pulse width in a unit of picosecond to femtosecond, and a broadband optical spectrum-generating optical fiber 24 that is connected with the ultra-short pulse fiber laser 22 via a lens 26 and has a non-linear coefficient of not less than 10 [W−1m−1] at a wavelength of the pulsed light and a magnitude of chromatic dispersion of not greater than 2 [ps/km/nm]. The pulsed light emitted from the ultra-short pulse fiber laser 22 is converted into a relatively flat super continuum over a broad band of approximately 1200 nm to 2000 nm by chromatic dispersion in the course of transmission through the broadband optical spectrum-generating optical fiber 24.

摘要： A fiber optic cable suitable for blowing into and through ducts containing pressurized gas, such as natural gas, has the fibers therein arranged in arrays that form longitudinally extending vents. The vents are blocked from transmission of any gas by each being filled with a compliant member which assumes the cross-sectional shape of the vents thereby blocking it. In a second embodiment of the invention, the first and third ferrules are fixed within the housing with their offset bores in alignment. A second ferrule is interposed between the first and third ferrules and is mounted in a rotatable member for misaligning the bore in the second ferrule with the bores in the first and third ferrule to produce attenuation of a signal passing through the ferrules by misaligning the fibers contained in the bores.
