Abstract: An apparatus for monitoring a performance of an Ethernet data stream, EDS, said apparatus comprising: an evaluation unit adapted to evaluate sync headers and block type fields of line code vectors of the Ethernet data stream, EDS; and a counter unit adapted to increment at least one performance counter in response to the evaluated sync header and the evaluated block type field of each line code vector of the Ethernet data stream, EDS.

Abstract: An apparatus for management of a spectral capacity of a wavelength division multiplexing, WDM, system includes at least one pair of transmission fibers provided for transporting optical signals. Each transmission fiber of a transmission fiber pair is connected to a first port of an optical circulator having at least two additional ports and adapted to transmit an incoming optical signal entering one of its ports via its next port. WDM subsystems configured with counter-propagating assignable wavelengths are connected to associated ports of the optical circulator of the apparatus.

Abstract: A chromatic dispersion compensation apparatus for automatic compensation of chromatic dispersion of signals transmitted via an optical link at predetermined wavelengths of WDM channels within a predetermined band. A tapping unit taps optical signals received by the chromatic dispersion compensation apparatus via the optical link at predetermined wavelengths and supply them to an optical coherent receiver adapted to tune its local oscillator to WDM channels to generate corresponding analog electrical signals of the WDM channels which are sampled by an analog digital converter to provide digital signal samples of WDM channels processed by a digital signal processor of the chromatic dispersion compensation apparatus to calculate an estimate residual chromatic dispersion value of the received optical signals. A tuneable dispersion compensation module is set to perform optical compensation of a residual chromatic dispersion of the received optical signals depending on calculated estimate residual chromatic dispersion value of the received optical signals.
