Abstract:

An optical data storage system and method of use thereof are presented. The optical data storage system includes one or more optical buffer modules connected in series. Each optical buffer module includes a cross connect. Each cross connect is connected, by a pair of inputs and outputs, to an optical data storage unit, for example, a fiber delay line, by a pair to either an optical packet network or a cross connect of a first adjacent buffer module in the series, and by a pair to a cross connect of a second adjacent buffer module in the series. The buffer module also includes a read signal output line which is connected to a read signal input line of the second adjacent buffer module for transmitting a read signal. A control module within each buffer module directs the passage of data through the cross connect.
