摘要： A node for managing an optical signal includes a first system optics card for providing channels to be transported over a first optical transport link and receives channels from a second optical transport link. Channels received over the second optical transport link are provided to an optical converter card for transport to a client device, for feedback onto the first optical transport link, or pass through to a second system optics card of the node. The first system optics card is capable of dropping network channels from the second transport link to associated client devices through optical converter cards and add client channels received from optical converter cards to the first transport link. The first system optics card may include one or more express input and output ports to couple with one or more other system optics cards in order to provide multiple degrees of communication capability.

摘要： A reconfigurable optical add drop multiplexer (ROADM) includes local interfaces at which optical signals of different wavelengths are locally input into the ROADM, and a network interface configured to connect the ROADM to a network from which multiplexed optical signals of different wavelengths are transmitted to the network. In a first configuration, the ROADM is configured to transmit from the network interface to the network multiplexed signals of different wavelengths having a first minimum frequency difference. In a second configuration, the ROADM is configured to transmit from the network interface to the network multiplexed signals of different wavelengths having a second minimum frequency difference. The second minimum frequency difference is greater than the first minimum frequency difference. This arrangement reduces the power of four wave mixing cross products produced when optical signals of three wavelengths are multiplexed and transmitted from the ROADM to NZDSF or DSF fiber types.

摘要： Example embodiments of the present invention relate to increasing an aggregate capacity of a network without using a centralized switch fabric. A method and corresponding apparatus in an example embodiment of the present invention relates to increasing overall aggregate capacity of a switching system. The example embodiment includes a first switching shelf having a first predetermined aggregate capacity, and multiple second switching shelves having a second predetermined aggregate capacity. The second predetermined aggregate capacity is less than the first predetermined aggregate capacity. The example embodiment increases the overall aggregate capacity as a function of connections between the first switching shelf and the multiple second switching shelves. The shelves are interconnected with interconnection links and can be configured to connect to additional shelves as the switching system grows to larger sizes. Embodiments can increase capacity while reducing cost within a network node.

摘要： The specification discloses methods and apparatus for selecting the better of two or more copies of a cell in a cell-oriented redundant switching system connected to an external communications network. In the preferred embodiment, the best cell copy selection aligns redundantly transmitted cell streams before selecting cells for insertion in the data stream. Because the streams are aligned before the selection is made, the best cell copy selector compares each cell at the same instant in time, rather than basing its selection on past events.

摘要： A communication system includes a first ingress content processor that receives information associated with a first traffic type. The first ingress content processor places the information associated with the first traffic type into a system cell having a common system cell format. A second ingress content processor receives information associated with a second traffic type. The second ingress content processor places the information associated with the second traffic type into a system cell having the common system cell format. A switch fabric receives system cells from the first and second ingress content processors. System cells from the first ingress content processor are automatically sent to the switch fabric while system cells from the second ingress content processor are required to be scheduled before being sent to the switch fabric. The switch fabric separately queues system cells carrying payloads associated with the first traffic type from system cells carrying payloads associated with the second traffic type. The switch fabric services system cells carrying payloads associated with the first traffic type prior to servicing system cells carrying payloads associated with the second traffic type.
