Patent number: 8244139Abstract: The present invention is a fiber optic data network, such as a passive optical network (PON), which includes a primary sub-network and a secondary sub-network. The primary sub-network may include a primary optical line terminal communicatively coupled to a plurality of primary optical network units. The secondary sub-network may include a secondary optical line terminal communicatively coupled to a plurality of secondary optical network units and to an intermediate optical network unit. The secondary sub-network may be communicatively coupled to the primary sub-network via the intermediate optical network unit, thereby allowing the PON to be configured so that the primary optical line terminal and the secondary optical line terminal are cascaded.Type: GrantFiled: February 12, 2009Date of Patent: August 14, 2012Assignee: Rockwell Collins, Inc.Inventors: Peter J. Morgan, Raymond Zanoni, Daniel E. Mazuk, Alistair J. Price

Publication number: 20110129230Abstract: Apparatuses, systems, and methods are disclosed that provide for an agile coherent optical modem that can generate agile RF waveforms and data rates on a generic opto-electronic hardware platform. An “agile coherent optical modem” [ACOM] approach to optical communications by employing a software configurable and adaptive technologies to the transport system. The ACOM generate agile RF waveforms and data rates on a generic opto-electronic hardware platform. By employing advanced communication techniques to the optical domain such as wavelength agility, waveform agility, and symbol rate agility, it is possible to enable robust optical communications. The ACOM allows for the transport capacity of a communications link to be varied, thereby accommodating variations in transport conditions, range, opacity, etc.Type: ApplicationFiled: November 1, 2010Publication date: June 2, 2011Inventors: Raymond Zanoni, David J. Copeland, Alistair J. Price

Patent number: 7868799Abstract: The present invention is a remote input analog-to-digital conversion (ADC) system. The system may generate low jitter, short duration optical pulses to allow for high performance sampling of an antenna signal at a remote end of the system. The system may utilize phase modulation and IQ demodulation (with a reference optical pulse stream) using separate analog-to-digital converters for I and Q to overcome linearity limitations. Low sampling rate analog-to-digital converters may be utilized by the system by using parallel, low optical pulse repetition rate paths and/or optical demultiplexer switching trees. The system is an optical fiber system.Type: GrantFiled: May 6, 2009Date of Patent: January 11, 2011Assignee: Rockwell Collins, Inc.Inventors: Alistair J. Price, Raymond Zanoni

Patent number: 7085042Abstract: Optical transmission systems of the present invention include at least one optical amplifier configured to provide optical amplification of one or more information carrying optical signal wavelengths. At least one optical amplifier is controlled based on an in situ performance characterization of the at least one optical amplifier and the transmission fiber. The in situ, or installed, performance characteristics of the optical amplifier can be characterized based on relative gain measurements over the signal wavelength range as a function of the supplied pump power. The installed characterization allows the optical amplifier performance and gain profiles to be tightly controlled over the signal wavelength range in the transmission system.Type: GrantFiled: May 16, 2005Date of Patent: August 1, 2006Assignee: Corvis CorporationInventors: Thomas D. Stephens, Raymond Zanoni
