    Abstract: A method and apparatus for increasing the operation lifetime of a beam tube, BT, (2) having an electron multiplier (2F) which amplifies a received ionic current with an electron multiplier gain, GEM, to provide an electrical current (IBT) output by the said beam tube, BT, (2), is provided. The method includes converting (S1) the electrical current (IBT) output by the beam tube, BT, (2) into an intermediate voltage (V1) amplified by a voltage amplifier (3C) with a variable gain, Gv, to provide a voltage signal (V2) used for a further processing and applied to a controller (3D), adjusting (S2) the electron multiplier gain, GEM, of the electron multiplier (2F) by changing an electron multiplier polarization voltage (UPOL) applied to the electron multiplier (2F) by a power supply unit (3F) controlled by an electron multiplier gain control signal (GEM-CRTL) generated by the controller (3D); regulating (S3) by the controller (3D) the electrical current (IBT) output by the said beam tube, BT, (2) to keep it below a characteristic current threshold, Ith, by adjusting the electron multiplier gain control signal (GEM-CTRL) until it reaches a predefined maximum value and regulating (S4) by the controller (3D) the voltage signal (V2) applied to the controller (3D) by increasing the variable gain, Gv, of the voltage amplifier (3C) to compensate for a drop of the electrical current (IBT) output by the said beam tube, BT, (2) caused by the aging of the electron multiplier (2F) until the applied voltage signal (V2) reaches a predefined minimum value.

    Abstract: The invention relates to a method of determining a time-of-flight of an optical signal between a starting point and a reflection point of an optical path, comprising: supplying to the path at least one optical probing signal; detecting an electrical return signal according to an optical return signal returning from the path in response to a corresponding one of the probing signals using direct detection; deriving at least one receive code sequence by sampling and slicing the return signal using a sampling rate corresponding to a bit rate of a sequence of pulses of the probing signal; determining a correlation function by correlating the transmit code sequence and the at least one receive code sequence; and identifying a main peak of the correlation function that corresponds to the reflection point and a time position of the peak, and determining the time-of-flight as the time position of the peak.

    Abstract: A method and apparatus for performing event-driven diagnostics and/or prognostics of a network behaviour of a hierarchical optical network comprising the steps of recording at least one set of historical multi-level events representing different hierarchy levels of said optical network; mining of machine learned event patterns within the recorded multi-level events; mapping the determined mined event patterns to a multi-level network topology of said optical network and/or to a channel connectivity of channels through said optical network; and matching observed real-time multi-level target events of said optical network with at least one of the previously determined mined event patterns and performing a unified cause and effect analysis of network states and/or network components of said optical network for a recognized matching event pattern using the network topology and/or channel connectivity associated with the matching event pattern.
