Abstract:

A metal substrate is fabricated and coated with a catalyst for ozone conversion of atmosphere passing through the substrate. A plurality of aluminum foil sheets that have been slit, stretched and twisted into a plurality of regularly repeating channels having geometrically shaped openings are serially positioned one on top the other to form a foil stack with channel openings partially blocked by channel walls of overlying foil sheets. Thicker covers with openings at the top and bottom of the stack form a sandwich and the sandwich pleated to form corrugations in a flexible but rigid sandwich substrate. The channel walls are coated with an ozone depleting catalyst which the ozone atmosphere contacts to remove ozone as the ozone atmosphere travels through the stack construction.

Abstract:

Optical regeneration is expensive to implement and maintain. A method or corresponding apparatus in an example embodiment of the present invention enables a user to plan an optical regeneration in a network with a reduction of optical regeneration compared to unplanned deployment. An optical regeneration planning tool according to an example embodiment of the present invention can graphically display a representation of a network topology with optical regeneration sites and enable the user to plan optical regenerations at a subset of the sites as a function of characteristics of models of optical network elements and paths within the network topology. Through use of the optical regeneration planning tool, a service provider can save on network deployment and future servicing of optical regeneration equipment.

International Classification:

G06F 15/173

US Classification:

709223

Abstract:

A method for planning a multi-phase network includes storing initial parameter values for parameters associated with first and second growth phases in a multi-phase network plan, wherein each of the first and second growth phases is characterized by sets of the parameters. The method also includes calculating an initial growth scenario including the first and second growth phases based on the initial parameter values, and adjusting a value for at least one of the parameters to produce a modified parameter value. The method further includes automatically calculating a new growth scenario based on the modified parameter value and at least a portion of the initial parameter values, and displaying the new growth scenario. A computer readable medium for implementing the method described herein is also provided.

Abstract:

Due to demand for more network bandwidth, a need for multi-user optical network topologies has, and will continue to, increase. A method or corresponding apparatus in embodiments of the present invention provide for an availability determination tool for determining and displaying wavelength and subrate availabilities within a network. Benefits of embodiments of a tool include allowing a user to identify the availability and capacity of any wavelength on any network, via an interactive graphical user interface, such as by using three-dimensional representations. In one embodiment, the disclosed availability determination tool allows users to locate and view any combination of available wavelengths between nodes in an optical network topology, and generate graphical and tabular reports of the availability in order to maintain an efficient and organized method or apparatus for determining and controlling wavelengths in a network. Consequently, service providers using the tool can keep performance rates high and costs low.

US Classification:

398 26

Abstract:

Signals propagating in wavelength division multiplexing (WDM) optical networks suffer from loss, which decreases optical signal-to-noise ratios (OSNRs) and degrades a quality of received transmissions. Present methods of boosting OSNRs involve regeneration using transponders, which scale in complexity with the number of WDM channels. Optical amplifiers may boost signal strength, but amplified spontaneous emission (ASE) noise often reduces OSNR despite increases in signal strength, although changing the amplifier operating settings may reduce emitted ASE noise power. A method or corresponding apparatus in an example embodiment of the present invention provides a planning tool for deploying optical amplifiers in an optical network in a manner that reduces the need for optical regeneration, reducing cost and complexity of the deployed network. In one embodiment, the disclosed planning tool may substitute models of high-gain amplifiers operating at low settings for models of low-gain amplifiers operating at high settings.
