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.
Abstract:
An optical fiber connector for terminating an optical fiber is provided. The optical fiber connector includes a housing configured to mate with a receptacle. The connector also includes a collar body disposed in the housing and retained between the housing's outer shell and a backbone. The collar body includes a swivel head coupled to a front end portion of the collar body, where the swivel head is configured to receive a ferrule. The swivel head is configured to pivot with respect to the front end portion of the collar body by a controlled amount upon a side pull force being placed on the connector and/or optical fiber.
Abstract:
An optical network comprises a fiber distribution cable and a terminal assembly. The terminal assembly receives a plurality of optical fibers from the fiber distribution cable and distributes one or more individual fibers to one or more single fiber bare-fiber holders that hold and protect each single fiber prepared and configured for splicing via an individual splicing element. The splicing element includes an alignment mechanism having a base plate and a clamp plate. At least one of the base plate and clamp plate is formed from a silica material and at least one of the base plate and clamp plate includes an alignment groove or channel configured to receive the first and second optical fibers in an end-to-end manner. The splice element also comprises an optical adhesive disposed in at least a portion of the alignment groove, wherein the optical adhesive is curable via actinic radiation.
Abstract:
An article comprises an optical fiber having a first end with a first end surface having a deposited coating only on a portion thereon. The first end can have a frustoconic or tronconic shape. The optical fiber can be utilized as a stub fiber in an optical device, such as an optical connector, receptacle or adapter. The deposited coating can be a wavelength selective multilayer thin film coating. The deposited coating can reflect a selected wavelength of light back to a central office to provide monitoring in a communication network, such as a PON.
Abstract:
Drop cable assemblies that can be routed from an outdoor terminal directly to an indoor wall outlet without disruption, and adhered to the interior of a dwelling after removal of the drop cable jacket and utilization of a pre-applied adhesive layer are described. Additionally, telecommunications systems utilizing such assemblies, methods of routing such assemblies and methods of making such assemblies are described.
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.
