Abstract: Provided are methods for producing a high strength, but easily deformed, polystyrene foam board that can endure repeated deformations from its original configuration into more complex curved shapes without damaging the board integrity or substantially reducing its structural strength. Also provided are rigid polystyrene foam boards produced by this method that exhibit improved bending and impact resistance while substantially retaining or improving other properties, for example, the thermal dimensional stability and fire resistance, exhibited by corresponding conventional XPS foam boards. The foamable compositions may incorporate one or more of a variety of polymer processing aids for the purpose of altering the performance of the final foam products, thereby allowing the properties of the final foam product to be customized to some degree.

Abstract: Thermal removal of optical fiber coatings by insertion through heated ferrules to form ferrule assemblies for fiber optic connectors, and related assemblies are disclosed. An optical fiber includes a glass fiber, having a cladding and core, surrounded by a protective coating. By removing the coating at an end portion of the optical fiber, the end portion may be precisely positioned and secured within a ferrule to enable reliable optical communications. The coating may be thermally removed, or substantially thermally removed, by inserting the optical fiber through a rear opening of the ferrule which has been heated above a temperature sufficient to change the coating to a non-solid state. In this manner, the coating may be efficiently removed from the end portion of the optical fiber while being inserted into the ferrule bore of the ferrule to enable efficient forming of a ferrule assembly for a fiber optic connector.

Abstract: Power distribution modules in distributed antenna systems include fan monitoring circuits for indicating an alarm condition to head-end equipment. The alarm condition can be used by system operator/owners that a fan is drawing excessive power, thereby detracting from system performance, or indicating that the fan may fail. The alarm condition signal can be returned to the head-end equipment via an uplink communication path between a remote unit powered by the module and the head-end equipment.

Abstract: An optical interconnection assembly for a spine-and-leaf network is disclosed. The optical interconnection assembly has spine MF components and leaf MF components. The spine MF components are optically connected to spine MF components of spine switches via spine patch cords. The leaf MF components are optically connected to leaf MF components of leaf switches via leaf patch cords. An array of duplex fiber optic cables serves to optically connect every spine MF component to every leaf MF component so that every spine switch is optically connected to every leaf switch. The optical interconnection assembly facilitates network scale out without the multifiber connections having to be broken up into multiple duplex connections using duplex fiber optic cables.

The first and second fold regions extend substantially across the length of the shingle blank. The second fold region is positioned between the first and third fold regions. A first perforation line is positioned between the second and third fold regions. A second perforation line is positioned between the first and second fold regions. A reinforcement material is positioned over the first perforation line and configured to reinforce the first perforation line. The reinforcement material includes apertures configured to allow an asphalt coating to bleed through the reinforcement material. The first and second perforation lines facilitate folding of the first and second fold regions on top of the third region to form a three layered stack.

Abstract: Embodiments disclosed herein include pre-terminated fiber optic connector sub-assemblies, and related fiber optic connectors, cables, and methods. In certain embodiments, an optical fiber stub is pre-installed in a ferrule bore of a ferrule of a fiber optic connector sub-assembly, to provide the pre-terminated fiber optic connector sub-assembly. The optical fiber stub can be pre-installed in the ferrule bore prior to termination of the fiber optic connector sub-assembly. Because the pre-terminated optical fiber stub disposed in the ferrule bore is not directly accessible through a ferrule body of the ferrule when a field optical fiber is disposed in the ferrule bore for fusion splicing, the ferrule has properties that allow thermal energy to be directed through the ferrule body into the ferrule bore. In this manner, the optical fiber stub pre-installed in the ferrule bore can be fusion spliced with the field optical fiber to terminate a fiber optic cable.
