Abstract
A method and apparatus for transporting data through a single optical fiber (SOF) the method comprising the steps of providing (S) transmission Tx, wavelength division multiplexed, WDM, data channels and reception Rx, wavelength division multiplexed, WDM, data channels having the same frequency grid with frequency gaps between the WDM data channels; frequency shifting (S) the Tx-WDM data channels and/or the Rx-WDM data channels to avoid spectral overlap between the Tx-WDM data channels and the Rx-WDM data channels; combining (S) the frequency shifted Tx-WDM data channels and the frequency shifted Rx-WDM data channels; and transporting (S) data via the combined WDM data channels through said single optical fiber (SOF) in opposite directions.
