Assignee:

Neptec Optical Solutions, Inc. - Knoxville TN

International Classification:

G02B 600

US Classification:

385134, 385 53, 385 62, 385 81

Abstract:

An extraction apparatus for being mounted on, and for selectively removing, a fiber optic connector component from a panel or a wall. The extraction apparatus includes a spring compression mechanism having a first compression member for selectively compressing a first retaining spring of the fiber optic connector component, a second compression member for selectively compressing a second retaining spring of the fiber optic connector component, and an actuator member for selectively moving the first and second compression members into contact with the first and second retaining springs such that the first and second retaining springs are compressed by the first and second compression members to permit removal of the connector component from the opening in the panel. The actuator member is disposed so as to extend through the opening in the panel as the connector component is positioned in the opening.

International Classification:

G02B 626

US Classification:

385 20, 385 21, 385 16

Abstract:

A network healing smart fiber optic switch for fast, automatic switching between multiple paths of an optical transmission line with minimal disruption. The network healing smart fiber optic switch accepts multiple fiber optic inputs and splits each optical signal into primary and secondary signals. The primary optical signals go to an optical switch, which selects the primary optical signal to send to the output based on a control signal from a controller. The secondary optical signals go to the controller, and based on the relative signal strength of the secondary optical signals, the controller outputs a control signal to the optical switch. The controller is in communication with a remote computer or another controller and the controllers output signal to the optical switch can be overridden by the remote computer or other controller. The network healing smart fiber optic switch automatically senses the condition, including faults, on fiber optic cables and switches between fiber optic cables. The switching occurs automatically and quickly with minimal disruption to the transmitted signal.

Assignee:

Neptec Optical Solutions, Inc. - Jefferson City TN

International Classification:

G02B 638

US Classification:

385 56, 385 70

Abstract:

An apparatus, comprising a removable optical adapter and receptor, which does not require the opening of a box to which the receptor is secured in order to remove the adapter. The adapter has a flange extending outwardly from the adapter body. The receptor is a mounting plate with a first aperture, which is slightly larger than the adapter flange, and a second aperture disposed parallel to the front surface. The receptor is fastened to a box, which contains at least one fiber optic connector. The adapter flange is inserted into the first aperture until it seats on a lip or shoulder adjacent to the second aperture. When the adapter is rotated, the adapter flange engages the second aperture. The receptor has a front and back surface which can be parallel, in which case the adapter, when inserted into the receptor, is perpendicular to the box face, or it can have a front and back surface which form the shape of a wedge, in which case the adapter forms an angle defined by the long axis of the adapter body and the plane of the box face. The removable adapter can be removed from the receptor, which is fastened to a box, without opening the box, and the adapter can be positioned such that the cable exits the adapter in the general direction of the cable routing.

International Classification:

G02B 638

US Classification:

385 58, 385 70

Abstract:

An apparatus which does not require the opening of a box in order to remove an adapter for fiber optic connectors. In one embodiment comprising a removable optical adapter and receptor, the adapter has a flange extending outwardly from an adapter body. The receptor is a mounting plate with a through-opening, which is slightly larger than the adapter flange, and a slot disposed parallel to a front surface. The receptor is foxed to a box, which contains at least one fiber optic connector. The adapter flange is inserted into the through-opening until it seats on a lip or shoulder adjacent to the slot. When the adapter is rotated, the adapter flange engages the slot. Another embodiment utilizes tabs on a removable adapter plate which are received by notches in a through-opening in the receptor. The removable adapter plate has a shoulder which prevents the plate from passing completely through the receptor. Once inserted, the plate is rotated and locked in place.

International Classification:

G02B 636

US Classification:

385 53, 385 56, 385134, 385136, 385137

Abstract:

An apparatus having at least one spring clip disposed on a connector adapter housing for releasably mating with an opening in an enclosure, the housing having fiber optic cables connected to opposed ends of the housing. When connected through an opening in an enclosure, the connector adapter housing maintains alignment of the opposed fiber optic cables for optical communication. The spring clip includes at least one clip member disposed upwardly from the surface of the spring clip. The spring clip is slidably inserted through a groove on at least one surface of the aligned connector housings. For release of the aligned connector housings, the spring clip is manipulated to slide along the groove, to compress the at least one clip member, allowing the housing to be removed from the enclosure opening for separation of the fiber optic cables from optical communication.

US Classification:

385 23, 385 18, 385 19

Abstract:

An optical switch utilizing an actuator to move an optical element into or out of an optical pathway is described. The optical element may be coupled to a movable shuttle and driven by a motor between two rest positions. The shuttle may be latched in the rest positions. The optical elements position may be controlled with a stop that contacts the shuttle to provide accuracy and precision about multiple axes. The material used to construct the actuators components may aid in repeatedly positioning the optical element with precision. The actuator may incorporate features that allow the optical element to be passively aligned in a bank of actuators to make a MÃN switch.

Abstract:

A method and apparatus of reducing the average particle size of silicon metal particulates employing a liquid oxidant extractant admixed with the silicon metal particulates while the silicon metal particulates are subjected to attrition in an attrition mill. An essentially oxidant-free silicon metal particulate product is produced, with the particulate product having an average particle size within that range of average particle sizes where the silicon metal particulates are susceptible to violent exothermic reaction with an oxidant.

Abstract:

An apparatus for switching a single optical signal to any one of several outputs. An input collimator transmits an optical signal that is reflected from two mirrors on an optical bench into an output collimator. Between the two mirrors is an actuator that interrupts the optical signal and effects another signal from an end collimator into one mirror and the output collimator. The alignment of the collimators and actuators relative to the optical bench is achieved by actively aligning the elements, which includes monitoring an optical signal passing through the collimator and using the signal as feedback for positioning control.
