    摘要： A high density panel mounting assembly has a first connector housing having first and second arrays of channels for receiving modified connectors, separated by a shelf. An adapter assembly for receiving the ferrules of the connectors has an interior wall having first and second arrays of bored projections forming sleeves for receiving the connector ferrules. The adapter assembly has a second connector housing substantially identical with the first connector housing mounted to or integral with the rear of the adapter housing for receiving individual connectors. Each of the connector housings has an array of apertures along the top and bottom surfaces for latching the connectors in place. Each of the connectors has a resilient latching arm having a distal end having a latching surface thereon which bears against the end of its corresponding aperture to latch the connector in place within the connector housing. The first and second connector housings each receives the connectors in an aperture, the width of which is substantially equal to the sum of the widths o the connectors so that the connectors, when in place, bear against each other to prevent lateral displacement thereof.

    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.

    摘要： Our method of making high bandwidth silica-based multimode optical fiber comprises provision of a non-circular preform, and drawing fiber of chiral structure from the preform. The non-circular preform can be made by maintaining the inside of the tubular preform under reduced pressure during at least part of the collapse, resulting in a non-circular core and cladding. It can also be made by removal (e.g., by grinding or plasma etching) of appropriate portions of the preform, resulting in a circular core and non-circular cladding. In the latter case, fiber is drawn at a relatively high temperature such that, due to surface tension, the cladding assumes substantially circular shape and the core assumes a non-circular shape. The chiral structure is imposed on the fiber in any appropriate way, e.g., by twisting during fiber drawing the fiber alternately in clockwise and couterclockwise sense relative to the preform.

    摘要： A laser cleaving apparatus for use in terminating optical fiber cable ends has a laser beam source, the output of which is directed through a beam distorting member, which produces a beam having a chisel shape with a substantially flat side normal to the axis of a connector fiber containing ferrule and focuses it onto the fiber at a point adjacent the ferrule end face with the flat side also adjacent the end face. A single step polishing stage polishes the cleaved fiber end face to make it flat and flush with the ferrule end face.
