Filed:

Dec 19, 2005

Appl. No.:

11/275197

Inventors:

William G. Mahoney - Suwanee GA, US
Robert R. Riggsby - Atlanta GA, US

Assignee:

Scientific-Atlanta, Inc. - Lawrenceville GA

International Classification:

H01R 13/24

US Classification:

439700, 439 63

Abstract:

An internal seizure assembly for providing connectivity with a conductor of a stinger without having access to the seizure assembly itself from the exterior. The seizure assembly includes a seizure lock nut for securing the seizure assembly within an opening within the interior of a housing. A seizure holder for receives a plunger therethrough and the plunger urges the conductor of the stinger into electrical contact with the seizure lock nut. In one embodiment, the plunger has an end keyed to the bottom of the opening in the housing to prevent the plunger from turning.

International Classification:

H04J 14/00

US Classification:

398 71, 398 66, 398 58, 398158, 398 33

Abstract:

A fiber-to-the-home (FTTH) system transmits forward and reverse optical signals, such as video, voice, and data signals, via optical fiber, and includes a plurality of home network units. The home network units include an optical receiver for receiving at least one of the video, voice, and data signals. Included is a plurality of gain stages that are distributed throughout the optical receiver. The gain stages include a preamplifier stage, two interstage amplifiers, and a postamplifier stage. Two gain control circuits automatically adjust the gain of the video signal based upon the input power level to the FTTH optical receiver. Additionally, a tilt network performs level compensation for externally located coaxial cable. A signal is then provided to a device located within a home via the coaxial cable at the proper RF level having low noise signals.

International Classification:

H01R 13/24

US Classification:

439700, 439 63

Abstract:

In one embodiment a self-contained seizure mechanism comprises a plunger, a spring, and a retainer guide having means for movably securing the plunger to the retainer guide. The retainer guide may have a receiving slot for receiving wings of the plunger and fingers for retaining the wings to the retainer guide and archways to guide a stinger conductor into contact with a crown of the plunger. The plunger and retainer may be snap-fit together to provide a seizure assembly that may be dropped in a receiving hole of a node housing and positioned to engage a stinger conductor and urge the stinger conductor into contact with a connector button on a lock nut.

International Classification:

G02B 6/00

US Classification:

385135

Abstract:

In one embodiment a fiber tray include an arrangement of retaining slots configured to receive retaining clips in a variety of different orientations and sizes. Retaining clips may have standardized sizes to correspond with the arrangement of retaining slots and to secure a variety of components to the fiber tray in different locations and orientations. Fiber management means may be provided to guide fiber optic cable from the components in a variety of orientations and locations. The fiber tray may be configured to move between a stowed position within a node housing in which the mounting surface of the tray faces downward and an access position in which the tray faces upward. The tray may be transparent to allow a technician to view the fiber arrangement without moving the tray from the stowed position.

US Classification:

398 67, 398 68, 398 72

Abstract:

Systems and methods for signal conversion with smart multitap are disclosed. Embodiments of the systems can be scalable to model different signal topologies, transmission frequencies, bandwidths, and distances. An exemplary embodiment of the systems and methods includes a fiber optic to RF converter and a smart multitap. Although a fiber optic to RF converter is used in exemplary embodiments throughout the disclosure, conversion between other signal topologies is within the scope of the disclosure. The smart multitap includes a multiple tap for distributing a signal to multiple terminals and a microprocessor to select a particular terminal for a signal. Exemplary embodiments include downstream implementations in which a stream is typically sent from a service provider server to a user. Alternative embodiments include downstream implementations as well as upstream implementations in which a user typically sends a stream to a service provider server.
