摘要： Optical switch packaging techniques and optical switch components are described. In one aspect, an optical switch component that includes a die mounted on an interposer is described. The die has an exposed array of mirrors that can be used as part of an optical switch. Typically, the interposer will also have a fiber array mount arranged to receive a fiber bundle and to position the fiber bundle appropriately over the array of mirrors. In some embodiments, an optical switch can be formed by putting together two mirror image interposer based optical switch components. When placing two interposer based optical switch components together, an alignment frame may be positioned between the interposers to help maintain a desired spacing between the respective arrays of mirrors. In some such embodiments, an inner housing is provided that encloses the dice, the fiber array mounts the alignment frame and portions of the interposers, but leaves connectors mounted on the interposers exposed. An outer housing may optionally be provided to encase the optical switch components and the inner housing. A resilient filler material may also be provided between the inner and outer housings to provide additional protection to the optical switch.

摘要： A method and apparatus are described for allowing diagnostics of a Passive Optical Network without significant loss of service to active customer sites. A plurality of primary transmitters operating at a first wavelength band are coupled to an optical switch of an optical network operating at a first wavelength band. A backup transmitter operating at the first wavelength band is coupled to a first input of a wavelength division multiplexer. An optical device operating at a second wavelength band is coupled to a second input of the wavelength division multiplexer. An output of the wavelength division multiplexer is coupled to an input of the optical switch. Outputs of the optical switch are coupled to a plurality of optical splitters. Each splitter has a plurality of optical outputs. The optical switch is reconfigured such that one of the optical switch outputs that was carrying traffic from one of the primary transmitters carries traffic from the backup transmitter after reconfiguring the optical switch.

摘要： A micro-electro-mechanical-system (MEMS) mirror device and methods for fabricating the same allow for a large range of angular motion for a center mirror component. The large range of angular motion for a center mirror component is dictated simply by a thickness of a substrate used or a thickness of a thick film used in making a support structure to support the center mirror component. The MEMS mirror device and methods for fabricating the same allow a large number mirror devices to be fabricated on a substrate. The MEMS mirror device includes a substrate. Electrodes are formed supported by the substrate. A support structure is formed adjacent to the electrodes. A hinge pattern and a mirror pattern having a center mirror component are formed such that the support structure supports the hinge pattern and mirror pattern. The support structure also supports the hinge pattern and mirror pattern such that a bottom surface of the center mirror component in a stationary non-rotating position is capable of exceeding a height of 50 &mgr;m above the electrodes.
