Filed:

Jul 21, 1998

Appl. No.:

09/119562

Inventors:

David R. Huber - Glenwood MD

Assignee:

Corvis Corporation - Columbia MD

International Classification:

H04J 1400

US Classification:

359128, 359117, 359127, 359130, 359124, 359134, 359139, 385 16

Abstract:

Apparatuses and methods are disclosed for use in optical communication systems. An optical system of the present invention includes an optical transmitter, an optical receiver, and an optical processing node optically connecting the transmitter and the receiver. The optical processing node includes at least one waveband selector configured to selectively pass at least one optical waveband of information including a plurality of information carrying wavelengths from the transmitter to the receiver. In an embodiment, the optical processing node includes a switch configured to separate an optical signal into optical wavebands of information and selectively pass the optical wavebands to the receiver without separating the plurality of information carrying wavelengths into individual wavelengths. In an embodiment of the optical transmission system, a plurality of nodes containing optical transmitters, receivers, and/or switching equipment are interconnected using optical processing nodes to form the network. The assignment of wavelengths to information and to destination can be performed at the client system interface with the optical network to provide for wavelength and waveband management without wavelength conversion.

International Classification:

H04J 1402

US Classification:

398 91, 398 76, 398141, 398163

Abstract:

An optical transmission system of the present invention includes at least one transmitter configured to receive information from a plurality of optical receivers and transmit the information in a plurality of information carrying optical signal wavelengths. At least one optical receiver is configured to receive a plurality of information carrying optical signal wavelengths and a local oscillator signal. The optical receiver converts a plurality of optical signal wavelengths into a corresponding number of electrical signal frequencies. The optical systems reduce the number of transmitters and receivers required interconnecting various optical systems, as well as providing multiple wavelength regenerators and converters and add/drop devices with increased capacity and system flexibility.

Appl. No.:

7/032246

Inventors:

David R. Huber - Rockville MD

International Classification:

H04B 900

US Classification:

370 3

Abstract:

A system for distributing wideband video information from a plurality of input sources to a plurality of users in which the input signals are converted into groups of packets of digital words, each packet corresponding to a video frame of information and each group comprising packets from a corresponding group of the input signals. The groups of packets are modulated onto optical signals which are multiplexed onto a single fiber optics line for transmission to the users. At the users, the signals are demultiplexed, demodulated, and input to a time domain routing switch which provides a predetermined number of output lines to each user. A control unit associated with each user issues control signals to the switch so as to route selected input signals to specified output lines to enable the user to access selectively and randomly any of the input signals.
