Abstract:

A computerized system and method for managing a passive optical network (PON) is disclosed. The system includes a detection and analysis module adapted for receiving uploaded measurement data from an optical line terminal (OLT) and at least one optical network terminal (ONT), and at least one of technical tools data, service failure data, and outside plant data. The detection and analysis module is adapted for determining a source of failure or potential failure in the PON by correlating the uploaded measurement data and the at least one of technical tools data and service failure data with information stored in a memory medium for the OLT and each ONT.

US Classification:

379068000

Abstract:

A system and method are disclosed for an opt-in voice session recording in a communication device. A system that incorporates teachings of the present disclosure may include, for example, a communication device () having a transceiver () for communicating with a second communication device, an audio system () for exchanging audible signals with an end user of the communication device, and a controller () for managing operations of the transceiver and the audio system. The controller can be programmed to establish () a voice session with the second communication device, transmit () to the second communication device a request to record the voice session, receive () from the second communication device a grant to record the voice session, and record () the voice session in response to the grant. Additional embodiments are disclosed.

International Classification:

H04J 14/00

US Classification:

398072000

Abstract:

A method and system for upgrading service to an optical network terminal among a plurality of optical network terminals on a passive optical network. The upgrade enables bidirectional communications between a central office and the optical network terminal over dedicated downstream and upstream wavelength channels outside the downstream and upstream wavelength bands associated with the passive optical network. The optical network terminal to receive upgraded service is disconnected from a passive optical splitter at a remote node serving the optical network terminal, and optically coupled to a port of the multi-port arrayed waveguide grating at the remote node. Wavelength taps are provided at the central office and the remote node to facilitate multiplexing and demultiplexing the dedicated downstream and upstream channels with the downstream and upstream wavelength bands associated with the passive optical network. In this manner, certain users on the passive optical network may receive service upgrades to wavelength specific services without affecting other users who remain on the passive optical network.

International Classification:

H04J 1402

US Classification:

359132

Abstract:

An SCM system for simultaneously reducing the concomitant problems of receiver complexity and dispersion penalty and without requiring the use of an expensive, high-bandwidth optical detector. The system provides both a dispersion reduction and a direct detection to the receiver, with microwave mixers and lithium niobate external modulators that produce sidebands that are only separated by a few gigahertz from a principal laser optical carrier. Digital data streams are independently impressed upon these sidebands for transmission over an ordinary single-mode fiber. Independent high-speed data streams are upconverted to microwave frequencies. These subcarriers are then combined with a microwave power combiner and amplified with a microwave amplifier. A solid-state 1550-nm laser carrier is modulated by the microwave subcarriers. An erbium-doped fiber amplifier (EDFA) is used just prior to long-distance transmission over ordinary single-mode fiber.

International Classification:

H04J 14/02

Abstract:

A system may use a single fiber combining module (SFCM) that combines multiple wavelength channels of different optical technologies over a single fiber. In an example, a SFCM may include a gigabit passive optical network (GPON) port, wherein the GPON passes signals at a first wavelength range; a XGS PON port, wherein the XGS-PON port passes signals at a second wavelength range; a dense wavelength division multiplexing (DWDM) port, wherein the DWDM port passes signals at a third wavelength range, wherein the first frequency range, the second frequency range, and the third wavelength range are different; and a common port connected with a fiber, the common port simultaneously combining signals from the GPON port, XGS-PON port, and the DWDM port.
