摘要： A size-expandable and bandwidth upgradable opto-electronic circuit switch (10) and corresponding methodology for full broadcast routing of a plurality of signals with 100% non-blocking are provided. The opto-electronic circuit switch (10) includes at least two input transmitters (22) for receiving electrical input signals and for converting these electrical signals into a corresponding optical input signal, such that each optical input signal is at a different wavelength carrier. Next, a multiplexer (24) is used to combine these optical signals into a single optical input using wavelength division multiplexing, a fixed equalizer (25) provides the same gain response among all signals, and an amplifier (26) optically amplifies this optical signal received from the multiplexer. A splitter (28) receives this amplified optical signal from the amplifier (26) and transmits it as a plurality of optical output signals to at least two optical receivers (30). Each optical receiver (30) selects one of the optical input signals from the optical output signal by its wavelength, and then converts this selected signal into an electrical output signal. Optional RF and digital subsystems are also provided to maximize the bandwidth utilization and further increase the number of input and output ports.

摘要： A loss-less optical cross-connect advantageously employs a plurality of optical rare earth-doped fiber optical amplifiers as gain-switched optical connections, for example, gain-switched optical distributors and gain-switched optical selectors. Each of the optical rare earth-doped fiber optical amplifiers acts as an ON/OFF switch. Also, both the gain-switched optical distributors and selectors employed in the optical cross-connect arrangement of this invention are a natural fit into today's optically amplified optical communication systems. In one embodiment, this is realized by employing a pump select circuit in conjunction with a plurality of pumps and the plurality of corresponding rare earth-doped fiber optical amplifiers. The particular pump and corresponding optical amplifier are selected by use of a control circuit arrangement to determine which output port or ports is (are) connected to the input port. The rare earth-doped fiber optical amplifiers and the corresponding pumps are employed advantageously for both the gain-switched optical distributors and the gain-switched optical selectors. In another embodiment, a so-called tuned pump arrangement is employed in conjunction with a plurality of filters and a corresponding plurality of rare earth-doped fiber optical amplifiers. A pump tuning arrangement is employed to control the tunable pump in order to select the appropriate one of a plurality of optical amplifiers to be activated, thus routing the input signals at any of a plurality of given wavelengths to the corresponding output line (or lines if broadcasting capability is employed). Again, the rare earth-doped fiber optical amplifiers and the corresponding pumps are employed advantageously for both the gain-switched optical distributors and the gain-switched optical selectors.

摘要： Optical communication apparatus for simultaneously and reconfigurably establishing optical communication channels, comprises at least one light source and a plurality of wavelength-selective detectors optically associated with each light source, the detectors arranged one behind another. The apparatus uses wavelength-division-multiplexing (WDM) to facilitate simultaneous and reconfigurable communication of one-to-many 2-D optical planes. This advance dramatically increases the system functionality of optical-plane interconnects. Such a system is realized by incorporating several multiple wavelength vertical-cavity surface-emitting lasers (VCSEL) into each transmitting pixel and incorporating wavelength selectivity into each subsequent detecting plane which will absorb one wavelength and be transparent to the rest; these structures can be fabricated by slightly modifying existing technology. This system allows for increased processing functionality of communicating both simultaneously and reconfigurably between many planes; broadcasting and dynamic independent interconnects are thus enabled.

摘要： A switching network that utilizes at least three degrees of freedom, time, wavelength and space. In one embodiment that involves point-to-point switching, each space channel between an input and an output is assigned a time slot and wavelength coordinate characteristic of the output and the input transmitter and output receiver are tuned to the appropriate time and wavelength coordinates and selective switching is used to complete the space channel between the input and output. In another embodiment for generalized switching, each input channel is assigned a set of space, time slot and wavelength coordinates and an input signal is broadcast to all of the outputs which selectively makes connection to those inputs with an appropriate set of coordinates.

摘要： An optical transceiver is provided with an optical front end for receiving signal light comprising an optical sub-channel, and for providing an electrical signal based on the signal light; a light source optically coupled to the optical front end for providing local oscillator light thereto for mixing with the signal light; an electro-optical modulator coupled to the light source for receiving output light therefrom and for modulating the output light with digital information to obtain modulated light; and a signal processor operably coupled to the optical front end. The signal processor is configured for processing the electrical signal to obtain a frequency offset of the sub-channel; and adjusting an optical frequency of the modulated light based on the frequency offset. When applied to a multiple-access environment, this may allow access nodes to generate optical sub-channels in the uplink direction using the downlink optical signal as an optical frequency reference.

摘要： Methods and systems enable optimized placement of wavelength shifters in optical networks. The wavelength shifters may include O-E-O regenerators for a single wavelength and all optical wavelength shifters for one or more wavelengths. An auxiliary graph is used to represent various links in a provisioned optical path. By applying cost values to each of the links, different types of optimizations for network resource utilization may be realized.

摘要： Systems and methods of affinity modeling in data center networks that allow bandwidth to be efficiently allocated within the data center networks, while reducing the physical interconnectivity requirements of the data center networks. Such systems and methods of affinity modeling in data center networks further allow computing resources within the data center networks to be controlled and provisioned based at least in part on the network topology and an application component topology, thereby enhancing overall application program performance. Using an affinity topology describing requirements for communications between applications and a network topology, network nodes are configured to satisfy multicast dispersion and latency requirements associated with communications between applications.

The monitor light generator controls a wavelength of the monitor light to be substantially the same as a wavelength of the optical signal. The switch guides the optical signal that arrives at the first optical port toward the first degree and guides the monitor light that arrives at the second optical port toward the second degree.

摘要： A system includes an optical fiber cross-connect module with upstream ports and downstream ports, a first set of optical fibers connected from optical line terminals to the upstream ports, and a second set of optical fibers connected to the downstream ports and a customer optical network unit. The optical line terminals provide multiple wavelengths carrying optical signals at different bitrates over the first set of optical fibers. The customer optical network unit includes a tunable filter configured to receive any one of the multiple wavelengths. The optical fiber cross-connect module divides the optical signals received at each of the upstream ports into each of the downstream ports, and the customer optical network unit may be tuned to pass through a particular wavelength from the multiple wavelengths.
