Abstract:
1. An Optical Code Division Multiple Access (“OCDMA”) storage system, comprising: an optical splitter optically interconnected with an optical network; a plurality of tunable filters optically interconnected with said optical splitter; a plurality of light detectors respectively optically coupled to said plurality of tunable filters, wherein each light detector of said plurality of light detectors is operable to convert a filtered optical signal filtered by a corresponding one of said plurality of tunable filters into a corresponding electronic data stream, wherein each said filtered optical signal comprises a single tuned wavelength of light; a plurality of nonvolatile storage volumes communicatively coupled to said plurality of light detectors, wherein each nonvolatile storage volume stores one of said corresponding electronic data streams such that said filtered optical signal associated with said corresponding data stream is reproducible; and a controller that controls the wavelength of light to be tuned by each tunable filter of said plurality of tunable filters, wherein said controller switches a first tunable filter of said plurality of tunable filters from a first wavelength of light that is also filtered by a second tunable filter of said plurality of tunable filters to a second wavelength of light that is also filtered by a third tunable filter of said plurality of tunable filters, wherein said optical splitter receives an OCDMA data stream from said optical network, wherein said plurality of nonvolatile storage volumes together store said OCDMA data stream such that said OCDMA data stream is reproducible.
