    摘要: Systems and methods for implementing test case generation with feedback are disclosed. An exemplary system for test case generation with feedback comprises a plurality of knobs identifying test values for a device under test. A plurality of buckets is each associated with at least one of the test values, each bucket having a weight value for the associated test value. A failure analysis module is operatively associated with the device under test, the failure analysis module changing at least some weight values based on feedback from test operations for the device under test. A test case generator selects test values for test operations based on the weight value for the associated test value.

    摘要: The present invention combines several features to create a novel type of optical telecommunications switching component using microwave waveguides as opposed to the usual methods employing light deflection or digital signal processing. Some of the components of the device include: (1) an optical crossconnect (OXC) which allows any combination of wavelengths to be added or dropped from an element to an optical network, (2) an optical add/drop multiplexer (OADM) which allows any wavelength to be converted to any other, (3) a microwave crossbar switch array optimized for this purpose, and (4) a means for reshaping the exiting signal from the microwave crosspoint switch array without regard to signal format and without need for complex and expensive digital signal processing. The minimal architecture for this functionality is shown to be three N×N microwave crossbar switch arrays.
