Abstract:
A transmitter device for transmitting optical data on an optical carrier source, said device comprising:a first modulator for receiving a first light input from a single source, said first light input having a first polarization state from said single source and modulating first coded data from a coder coupled thereto on said first light input; a second modulator for receiving a second light input from said single source having a second polarization state from said single source and modulating delayed first coded data representative of said first coded data from said coder on said second light input; at least one output port coupled to said first and second modulator for transmission of said first coded data and said delayed first coded data over an optical medium; and first and second polarization selectors coupled, respectively, prior to said first and second modulators, said polarization selectors being operable to select a polarization state being output there from.
