SOLUTION: Various types of passive optical networks operate simultaneously in a passive optical network system having an optical line terminal, a passive remote node, and a plurality of multiple optical network devices. Downstream data are orthogonal frequency division multiplexed onto a single wavelength optical carrier transmitted on a first downstream optical beam from the optical line terminal to a splitter in the passive remote node. The first downstream optical beam is divided into a plurality of second downstream optical beams to be transmitted to a specific optical network device. Upstream data are orthogonal frequency division multiplexed onto a single wavelength optical carrier transmitted on a second upstream optical beam from each optical network device to a coupler in the passive remote node. The upstream wavelength for each optical network device is different. The wavelength division multiplexed optical beam is transmitted from the passive remote node to a parallel signal detector in the optical line terminal. COPYRIGHT: (C)2009,JPO&INPIT

    摘要: PROBLEM TO BE SOLVED: To achieve the reduction of bogus warnings which exceeds the reduction of the bogus warnings obtained by using synchronization constraints. SOLUTION: A system and method for program verification includes generating a product transaction graph for a concurrent program, which captures warnings for potential errors.
