Patent number: 8086101Abstract: A multi-city wavelength link architecture is used to distribute spectral bands received on input optical signals among output optical signals. Such an architecture may include an optical wavelength cross connect having multiple input ports, multiple output ports, and a wavelength routing element that selectively routes wavelength components between one optical signal and multiple optical signal. Such an optical wavelength cross connect will generally receive cross-connect-input optical signals at the input ports and transmit cross-connect-output optical signals from the output ports. Methods are used to increase the number of cities that may be accommodated by the architecture without disrupting through traffic between the existing cities.Type: GrantFiled: April 19, 2002Date of Patent: December 27, 2011Assignee: Altera CorporationInventors: S.

Patent number: 7194206Abstract: An optical cross connect architecture is provided in which the density of spectral bands on optical signals through the cross connect may vary. The general functionality of such variable-density optical cross connect is to receive input optical signals that each have multiple spectral bands and to transmit output optical signals each having one or more of the spectral bands. A concentrator redistributes the spectral bands from the input optical signals among a smaller number of first intermediate optical signals. A core cross connect redistributes the spectral bands on the first intermediate optical signals among second intermediate optical signals. An expander redistributes the spectral bands on the second intermediate optical signals among a greater number of output optical signals.Type: GrantFiled: May 15, 2002Date of Patent: March 20, 2007Assignee: Altera CorporationInventors: Robert T.

Patent number: 7079723Abstract: An optical wavelength cross connect is provided to receive multiple input optical signals that each have multiple spectral bands and to transmit multiple output optical signals that each have one or more of those spectral bands. The optical wavelength cross connect includes multiple wavelength routing elements, which are optical components that selectively route wavelength components between one optical signal and multiple optical signals in either direction according to a configurable state. As used within the optical wavelength cross connect, each of the wavelength routing elements receives at least one optical signal corresponding to one of the input optical signals. A mapping of the spectral bands to the output optical signals is determined by the states of the wavelength routing elements.Type: GrantFiled: March 8, 2002Date of Patent: July 18, 2006Assignee: PTS CorporationInventors: Edward J.

Patent number: 6853811Abstract: An optical ring is provided for propagating optical signal pairs over wavelength connections between nodes. Each optical signal pair includes two signals at different wavelengths. At one or more of the nodes, one signal of the pair acts as a transmit signal and the other acts as a receive signal. If a failure is detected the optical signal pair is redirected over a protection path without changing the wavelengths of the transmit and receive signals. This may be achieved by reversing a propagation direction for each of the signals comprised by the redirected optical signal pair.Type: GrantFiled: September 12, 2001Date of Patent: February 8, 2005Assignee: PTS CorporationInventors: Ronald A Wahler, Edward J Bortolini

Patent number: 6813408Abstract: Methods are provided for upgrading a Ki1×Kj1 optical wavelength cross connect to a Ki2×Kj2 optical wavelength cross connect without taking the cross connect out of service. Each Ki×Kj cross connects has a working fabric with multiple optical components and has a protection fabric. The working fabric receives optical traffic from Ki input optical signals and transmits Kj output optical signals. The protection fabric is configured to bypass at least one of the optical components in the event of a fault. The upgrade of the Ki1×Kj1 optical wavelength cross connect proceeds by upgrading the protection fabric to accommodate at least Ki2 input optical signals. Sequentially, each of the optical components included on the working fabric is upgraded. The optical traffic received by that optical component is bypassed to the protection fabric. Thereafter, that optical component is upgraded to accommodate at least Ki2 input optical signals.Type: GrantFiled: March 8, 2002Date of Patent: November 2, 2004Assignee: PTS CorporationInventor: Edward J.

Patent number: 6690853Abstract: A tunable demultiplexer accepts an input optical signal that has multiple spectral bands and provides multiple output signals. Each of the output signals corresponds to a selected one of the spectral bands.

Patent number: 6687907Abstract: Detecting tampering of an incoming cable to which a network interface unit (NIU) is connected by testing for the reflected signal that is present when the signal being transmitted to the head end is not connected to a properly terminated coaxial cable. In particular, by comparing the phase of the transmitted signal from the NIU with that of the reflected signal, a distinction can be made between a signal that travels many feet before being reflected back and a signal that reflects back right or near the connector of the NIU. Only the latter is used as a stimulus to indicate tampering since the first is likely caused by cable personnel disconnecting the cable further into the network. The key difference between the two types of reflected signals is the time delay of the reflect signal with respect to the transmitted signal from the NIU.Type: GrantFiled: August 18, 2000Date of Patent: February 3, 2004Assignee: Lucent Technologies Inc.Inventor: Edward J Bortolini
