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 feeds each of multiple fiber optic inputs to a splitter. One of the outputs of the splitters go to an optical switch, which selects the optical signal to send to the output based on a control signal from a controller or analog selection circuit. The other outputs of the splitters go to the analog selection circuit, which outputs a control signal to the optical switch. The analog selection circuit compares the primary optical signal to a selected setpoint to determine the signal's validity. The analog selection circuit routes an alternate, or secondary, optical signal upon failure of the primary optical signal. After the primary signal is restored and valid for a specified period, the analog selection circuit deselects the secondary optical signal and routes the primary optical signal.

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.

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.

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 controller's 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.

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.
