摘要： A system and method for connectivity configuration of a network node permits an optical signal to be passed through the node and shifted from a first connector position to a second connector position that is offset from the first connector position. The shifted optical signal permits a number of distant nodes in the network to be reached with a direct optical connection, which can be configured to be bidirectional. The disclosed connectivity configuration reduces the cabling requirements for the network and simplifies the interconnections.

摘要： Systems and methods for routing wavelengths in an optical network include responsive to a path request for a wavelength or group of wavelengths, determining a path through the optical network; determining a location on the path where wavelength blocking should occur to form a loop-free path in the optical network; and setting the wavelength blocking at the location. The optical network can utilize a broadcast and select architecture and the wavelength blocking is configured to prevent the wavelength or group of wavelengths from looping back on a port where the wavelength or group of wavelengths has already been received on. The optical network can utilize an all-broadcast architecture and the wavelength blocking is configured to prevent multiple paths for the wavelength or group of wavelengths by constraining the wavelength or group of wavelengths to a single path through the optical network.

摘要： An architecture for a fiber optic communication system that uses only two levels of switches, Tier 1 and Tier 3, is described. The architecture allows one to omit the conventional Top of Rack switch level and the conventional Tier 2 switch level while maintaining performance and throughput. The cost to construct and install the improved switch architecture is lower than the cost of the conventional architecture. There are also described a number of transceivers that are suitable for use in the architecture disclosed. The transceivers employ silicon PIC chips that include high contrast silicon waveguides ion the chip and that connect to various configurations of optical fibers. The transceivers provide enhanced switching capacity with fewer devices.

摘要： The present invention provides a high capacity switching system for use in a transport network, which contains a number of input/output subsystems and a central interconnection means configurably interconnecting the input/output subsystems. The subsystems have input/output line modules for receiving and transmitting data signals to and from transmission lines of the network, one or more link modules connecting the subsystems to the interconnection means, and local switching means switching data signals in time and space domain between the input/output modules and the one or more link modules within one subsystems. The link modules are adapted to aggregate data signals from different input/output line modules of the same input/output subsystems and destined to input/output line modules of another one of said input/output subsystems into signal bursts and add a payload gap to each signal burst. The switching system further has a scheduler which configures the interconnection means during the payload gaps to switch the signal bursts to their destination subsystems.

The output modules comprise optical receivers each configured to receive optical signals at a different wavelength. The input modules receive electric signals carrying data cells to be routed. Each input module comprises optical transmitters, each configurable to generate an optical signal at a different wavelength, and routing apparatus comprising output ports.

摘要： A fast optical switch is needed to realize an economical and scaleable optical-core network. In the disclosed optical switch, switching is effected by rapid wavelength conversion. Either channel switching, Time Division Multiplex (TDM) switching or both may be provided by the fast optical switch. The operation of the fast optical switch is enabled by a fast scheduler. The throughput of the optical switch may be increased through a process of bimodal pipelined connection-packing. An in-band exchange of control signals with external nodes may serve to minimize the control overhead. Such control signals may include time-locking signals and connection-requests. A modular structure may be configured to comprise several fast optical switches to yield a high-speed, high-capacity, fully-connected optical switch.
