Abstract: A method for establishing an embedded optical communication channel in an optical WDM transmission system including: creating, at the central network device, a broad-band optical signal, supplying the broadband optical signal, transmitting the broadband optical signal and the plurality of second optical channel signals to an optical demultiplexer device, transmitting an optical signal consisting of a dedicated second optical channel signal and a filtered broadband optical signal; receiving the optical signal and creating a corresponding electrical receive signal and extracting the electrical signal corresponding to the filtered broadband optical signal from the electrical receive signal and detecting whether the electrical signal contains information intended for the respective first channel transceiver.

Abstract: An optical transmission system method including generating for a tunable laser a pilot tone having an adjustable pilot tone frequency identifying a wavelength division multiplexing channel used by the tunable laser; multiplying the pilot tone with pilot tone data to provide a pilot tone data signal; supplying the pilot tone data signal and a high frequency data signal to the tunable laser generating an optical laser signal output by the tunable laser responsive to the supplied signals; transporting the optical laser signal to a central wavelength to locker; converting the received optical laser signal to provide a pilot tone data signal for wavelength division multiplexing channels demodulated to detect the pilot tone and the pilot tone data for each individual wavelength division multiplexing channel; and identifying the wavelength division multiplexing channel on the basis of the pilot tone frequency of the detected pilot tone and evaluating the pilot tone data.

Abstract: Arrangement for transmitting an optical digital WDM signal over an optical transmission link or a passive optical network, the signal (SWDM) including N optical channels matching a given optical frequency grid. The scheme includes supplying the WDM signal (SWDM) to a near end of the optical transmission link or a near end of the passive optical network; receiving the WDM signal (SWDM) at a far end of the optical transmission link or at one or more far ends of the passive optical network; separating the optical channel signals (si(t)) by splitting and bandpass filtering the WDM signal (SWDM) received; and converting the optical channel signals (si(t)) into electrical channel signals using direct optical detection. The signal (SWDM) is created such that neighboring channel signals (si(t)) are orthogonally polarized and are conditioned with specific pre-distortion.
