  • Publication number: 20170373386
    Abstract: A system having a concealed communications element like a telecommunication antenna is described. More specifically, The system has a communications element that is concealed by a highly reflective multilayer polymer optical film 200. The first element of the multilayer polymer optical film is a core layer 202 that is made up of a multilayer optical stack. The multilayer optical stack of core layer 202 includes two alternating polymeric layers. The multilayer polymer optical film may optionally also include a protective layer 204 (for example, a hardcoat or an over laminate) that is positioned between the viewer and the core layer. The protective layer 204 may include one or more UV absorbers to aid in durability of the multilayer polymer optical film against UV-degradation. Multilayer polymer optical film 200 may optionally also include an adhesive layer 208 that is positioned between the core layer 202 and a surface onto which the multilayer polymer optical film is to be adhered.

  • Publication number: 20140037250
    Abstract: An optical fiber connector includes a housing configured to mate with a receptacle, a collar body that includes a fiber stub and a mechanical splice device, a backbone to retain the collar body within the housing, and a boot. The backbone includes a cable jacket clamping portion to clamp a cable jacket that surrounds a portion of the terminated optical fiber upon actuation. The boot actuates the cable jacket clamping portion of the backbone upon attachment to the backbone. A method for terminating the optical fiber in the field includes slitting or removing a portion of the cable jacket prior to splicing the optical fiber to the fiber stub. The method also includes utilizing a protective sheath or tube to protect exposed portion of the fiber cable and provide structural integrity to the optical connector.

  • Publication number: 20120141082
    Abstract: An optical fiber cleaver to cleave an optical fiber is provided. The optical fiber cleaver comprises a generally planar main body and a generally planar flap portion movable with respect to the main body. The optical fiber cleaver also includes a first clamp disposed on the main body to receive and hold a first bare glass portion of the optical fiber and a second clamp disposed on the flap portion to receive and hold a second bare glass portion of the optical fiber. A shuttle device is disposed on the main body axially between the first clamp and the second clamp and is configured to move laterally with respect to an axis of the optical fiber. The shuttle device further includes a flexible abrasive material configured to contact the optical fiber and create a flaw on an outer surface thereof during cleaving.

  • Publication number: 20110030190
    Abstract: A system and method for providing a final drop in a living unit in a building. The system comprises a point-of-entry unit, such as a low profile base unit, disposed within the living unit at a location corresponding to an access position of horizontal cabling disposed in a hallway of the building that provides a first anchor point. The system also includes an adhesive-backed duct, having one or more communication lines disposed therein, mountable to a wall within the living unit. The system also includes a second anchor point, such as a wall receptacle, disposed within the living unit to receive a first communication line via the duct. The components of the system are also designed with very low impact profiles for better aesthetics within the living unit.

  • Publication number: 20110030832
    Abstract: A duct for distributing one or more communication lines comprises an elongated body having a length and a conduit portion with a lengthwise bore formed therein, the conduit portion containing one or more communication lines. The duct also includes a flange extending lengthwise adjacent the elongated body to mount the duct to a mounting surface. The duct also includes an adhesive layer disposed on a bottom surface of the flange. The duct may further include a strength member extending lengthwise with the flange. The strength member may be disposed between the bottom surface and the adhesive layer or within the conduit. The duct may include an open slot in the top to allow for insertion and removal of the communication line. The duct may also be configured such that the conduit portion is attached to the flange structure via a thin web of material having a thickness such that upon modest application of a peeling force, a segment of the conduit portion is detachable from the flange structure.

  • Patent number: 6172329
    Abstract: This invention concerns a process useful for increasing the accuracy of the shape of a laser ablated feature formed on a substrate, especially where the substrate is a polymeric article. The process includes irradiating the polymeric article with laser light that has passed through a retardation plate selected from stationary adjustable plates, rotating plates or spinning plates, preferable in multiples of quarter-waves or half-waves. This invention also concerns a laser apparatus useful for making ablated features in a substrate having a radiation source; a mask positioned between the radiation source and a substrate to be irradiated, and a retardation plate which is stationary and adjustable, rotating or spinning plates.

  • Patent number: 6120976
    Abstract: A method and apparatus for ablating features in a substrate, the apparatus includes a radiation source and first and second rotating transparent uniformly thick disks positioned between the radiation source and a substrate to be irradiated. The method comprises irradiating the substrate with radiation that has passed through the first and second rotating disks, wherein the first and second disks are independently rotating at different angular velocities to create a predetermined irradiation pattern on the substrate. The disks may have a relative acceleration. The method and apparatus may be used to ablate nozzles having longitudinal axes which are non-orthogonal with the surface of the substrate and which are not parallel to each other.
