摘要： A switch for selectively coupling light from two input fibers to a selected two of plurality of output optical fibers. The switch was designed to handle standard Fiber optical connectors which have been polished and meet the specifications for the optical performance. The duplex mechanical switch creates a method to physically switch two fibers (Duplex) to another two fibers (Duplex). The performance regarding insertion losses, back reflection, crosstalk, immunity against backscattering of light and insensitivity to the wavelength of the light is consistent with this mechanical switch.

摘要： A method and system implementations thereof include receiving data from a passive optical network (PON) outside a building; wirelessly transmitting the received PON data to inside the building; and applying the received PON data to a network inside the building. The data received outside the building is from an optical line termination (OLT). The PON data wireless transmitted inside the building may be applied to an optical line terminal (ONT) inside the building. Alternatively, the wirelessly received PON data may be converted to Ethernet format and applied to a user interface and/or a gateway interface all inside the building. The wireless transmission of PON data may be via a first transceiver mounted on a surface outside the building and a second transceiver mounted on a surface inside the building. The surface may be a corridor, a window, a door, a walls and a façade.

摘要： Optical networks may store information or data therein by maintaining the information or data in motion. The optical networks may include optical fiber rings configured to receive optical signals comprising the information or data and to circulate the optical signals within the optical fiber rings. The optical signals and the information or data may be transferred out of the optical fiber rings in order to amplify the optical signals (e.g., to overcome losses due to attenuation within the optical fiber rings), to analyze the optical signals according to one or more processing techniques, or to transfer the information or data to another computer device upon request. If continued storage of the information or data is required, an optical signal including the information or data may be transferred back into the optical fiber rings and may continue to circulate therein.
