20160036553 | NODE APPARATUS - The present invention provides a node apparatus, where two N×N wavelength selective switches are used to form a parallel-connected structure, and two ends of each power splitter are separately connected to input ends of the N×N wavelength selective switches, and two ends of each power combiner are separately connected to output ends of the N×N wavelength selective switches, thereby transferring route switching selection work originally performed between multiple 1×M wavelength selective switches to the inside of the N×N wavelength selective switch for implementation. Compared with an original structure using discrete components, the node apparatus is simplified, and when a traffic volume expands, the number of module slots on a line side does not need to be increased, thereby reducing usage costs eventually. The present invention is used for signal transmission in a node. | 2016-02-04 |

20160036555 | ALL-OPTICAL TIME SLICE SWITCHING METHOD AND SYSTEM BASED ON TIME SYNCHRONIZATION - An all-optical time slice switching method based on time synchronization is provided. With the method, continuous data streams in an optical network are assembled to time domain periodic optical time slices and are transmitted in an asynchronous transmission mode. Network nodes obtain high precision synchronization time via a network and control optical switches to switch arriving optical time slices to a target port at precise time points periodically, therefore all-optical switching is implemented. When a connection request arrives, an available path, a wavelength and time slots to be occupied are calculated by a source node according to information on available time slots of the optical network, and the time slots are reserved by a connection management module. After the time slots are reserved, the source node send optical time slices carrying services periodically at reserved time slots. A destination node restores the optical time slices to the data streams. Compared with an existing switching technology, the all-optical time slice switching method has remarkable advantages that reliable and flexible all-optical switching at sub-wavelength granularity can be implemented without participation of all-optical buffers and all-optical logic apparatus. | 2016-02-04 |
20160036556 | SIGNAL JAMMING SUPPRESSION - Provided are processes for suppressing jamming signals that may include use of a signal processing circuit. A signal processing circuit can be configured to obtain a jamming signal and a feedback signal, process the jamming signal and the feedback signal to determine a cancellation signal for use in suppressing the jamming signal, and output the cancellation signal to a radio-frequency transmitter. The signal processing circuit may be further configured to obtain a transmission signal, determine a jamming channel from the jamming signal and a feedback channel from the feedback signal, and combine the transmission channel, jamming channel, and feedback channel to determine a transfer function, where the transfer function is configured to determine the cancellation signal. | 2016-02-04 |
