An optical system including first and second optical elements for guiding light therein. For each optical element, the propagating light enters or exits the optical element through a coupling surface of the optical element. The coupling surfaces of the optical elements face, and align with, each other so that light propagating in one of the optical elements exits the optical element through the coupling surface of the optical element and enters the other optical element through the coupling surface of the other optical element. The coupling surfaces are separated from each other and define a region therebetween. The region is filled with a coolant, the coolant substantially surrounding at least one of the first and second optical elements.

A distribution cabling tape comprises a resilient polymeric base sheet having a first major surface and a second major surface, the first major surface having a continuous lengthwise channel formed in a first portion thereof. The tape also includes an adhesive layer disposed on a second and third portion of the first major surface, the adhesive layer capable of adhering to a concrete or asphalt surface, such as a road, curb, or walkway.

Distribution cabling tape and system

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. The first element of the multilayer polymer optical film is a core layerthat is made up of a multilayer optical stack. The multilayer optical stack of core layerincludes two alternating polymeric layers. The multilayer polymer optical film may optionally also include a protective layer(for example, a hardcoat or an over laminate) that is positioned between the viewer and the core layer. The protective layermay include one or more UV absorbers to aid in durability of the multilayer polymer optical film against UV-degradation. Multilayer polymer optical filmmay optionally also include an adhesive layerthat is positioned between the core layerand a surface onto which the multilayer polymer optical film is to be adhered.

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.

An LC format optical connector for terminating an optical fiber includes a housing configured to mate with an LC receptacle. A backbone is configured to engage an outer surface of the outer shell of the housing and includes a mounting structure that is configured to engage a boot. A collar body is retained between the outer shell and the backbone and includes a fiber stub disposed in a first portion of the collar body, the fiber stub being mounted in a ferrule. A mechanical splice is disposed in a second portion of the collar body, the mechanical splice configured to splice the fiber stub to the optical fiber. The backbone also includes a fiber jacket clamping portion to clamp a jacket portion that surrounds a portion of the optical fiber upon actuation.

Field terminable optical connector with splice element for jacketed cable

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.

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.

Ablated laser feature shape reproduction control

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.
