System and method for transmitting optical signals

摘要

A method of transmitting optical signals in a submarine optical network and an optical unit for performing the method, the optical unit is configured for receiving an optical signal comprising a plurality of wavelengths where at least some of the wavelengths comprise traffic data. The optical unit includes a processor unit which is configured for scrambling the shape of at least one wavelength comprising traffic data of the optical signal so as to make said traffic data of said at least one wavelength undetectable for a receiver station.

主权项

1. An optical unit for a submarine optical network, the optical unit being configured to receive an optical signal comprising a plurality of wavelengths, at least some of said plurality of wavelengths comprising traffic data, and to transmit said optical signal, the optical unit comprising:
a demultiplexer for receiving the optical signal and separating it into a wanted signal of one or more wavelengths and an unwanted signal of one or more wavelengths; a processor unit configured to receive the unwanted signal and scramble data of at least one wavelength of the unwanted signal to generate a scrambled signal undetectable for any receiver station; and a multiplexer configured to multiplex said scrambled signal with said wanted signal to transmit a multiplexed signal.
