Abstract
An optical transmission system of the present invention includes at least one transmitter configured to receive information from a plurality of optical receivers and transmit the information in a plurality of information carrying optical signal wavelengths. At least one optical receiver is configured to receive a plurality of information carrying optical signal wavelengths and a local oscillator signal. The optical receiver converts a plurality of optical signal wavelengths into a corresponding number of electrical signal frequencies. The optical systems reduce the number of transmitters and receivers required interconnecting various optical systems, as well as providing multiple wavelength regenerators and converters and add/drop devices with increased capacity and system flexibility.
