摘要： The present invention provides a variety of methods and apparatus for monitoring signal quality and switch operation for optical switches in an optical cross connect. The signal quality can be checked by using a beamsplitter to reflect a portion of the light beam carrying the signal onto a photodetector which is connected to a device which can monitor loss of signal, loss of frame, and other transmission characteristics. The position of a switch or waveguide can be monitored by circuits which detect variable levels of resistance and capacitance based on the switch's position or by reflecting probe light beams off the back of the switching mirror. The present invention also provides a method for determining if the signal quality photodetector is functioning correctly.

摘要： A layered optical cross-connect switches signals from a first set of optical fibers to a second set of optical fibers. The optical cross-connect comprises at least two switching layers. The input ports and the output ports of each switching layer are fully interconnected. At least one switching layer is configured to switch at least two signals from the same optical fiber from the first set of optical fibers to the second set of optical fibers. For example, in a wavelength-division multiplex (WDM) system, a switching layer can switch signals from different WDM channels having different wavelengths.

The multiplexed input optical signals are demultiplexed to provide isolated input optical signals to an optical switch matrix comprising switches in an array of lines and column, the isolated input optical signals being inputted in a direction parallel to a line of switches in the optical switch matrix. The added optical signal is input in a direction parallel to a column in the optical switch matrix. An output line is selected and the switch that is on the column on which the added optical signal is inputted and on the selected output line is switched.

摘要： An optical switch device redirects a beam of light traveling along a first direction to a second direction and includes a base member, a reflective panel and an actuator. The reflective panel is pivotally connected to the base member and moves between a reflective state and a non-reflective state. In the reflective state, the reflective panel is disposed to redirect the beam of light from the first direction to the second direction. In the non-reflective state, the reflective panel is disposed to permit the light beam to travel along the first direction. The actuator is connected to the base member and the reflective panel and is operative to cause the reflective panel to move to and between the reflective state and the non-reflective state. An array of optical switch devices can be arranged to form a free-space optical matrix crossconnect apparatus.

摘要： Integrated connection-verification system for use in a micro-electro-mechanical system (MEMS) crossconnect device. The system uses application of a dithering signal such as a sinusoidal bias to an electrode plate associated with a micro-mirror switching element to dither the micro-mirror. The optical signal from the dithering micro-mirror is fed through a beam splitter, a portion of the optical signal thus being directed to a photodetector. If intensity modulation in the optical signal corresponding to the frequency of the dithering signal is detected by the photodetector associated with the micro-mirror, the connection path between the desired input and output ports is verified.
