  • Patent number: 11652544
    Abstract: The present disclosure relates to an optical time domain reflectometry method including the steps of feeding a plurality of unipolar optical probe signals to a near end of an optical path under test, receiving a corresponding plurality of reflected unipolar optical receive signals, creating a corresponding plurality of digital receive data signals, calculating at least one correlation signal by correlating the digital receive data signals with a bit sequence corresponding to a respective probe bit sequence, and determining the signal propagation delay between the near end of the optical path and a respective reflective position. The present disclosure also relates to an optical time domain reflectometry system in which this method is implemented and a computer program having instructions to cause the optical time domain reflectometer and to execute the method herein.

  • Patent number: 9813184
    Abstract: The invention relates to a method for establishing a communication channel, preferably an embedded control channel, between a central network node and at least one network unit to be integrated in a communication network including the central network node and an arbitrary but limited number of network units. The central network node is adapted to create and output a wavelength-division multiplex (WDM) downstream signal including downstream channel signals to be transmitted to the network units and to receive a WDM upstream signal including upstream channel signals created by the network units.

  • Patent number: 9467316
    Abstract: Disclosed is a method for transmitting a low-frequency signal over a data transmission link using a digital high bit-rate signal including the steps of creating a modulated digital high bit-rate signal the average power of which varies according to the low-frequency signal, supplying the modulated digital high bit-rate signal to a first end of the data transmission link, receiving the modulated digital high bit-rate signal at a second end of the data transmission link or at an intermediate node of the data transmission link, and detecting the low-frequency signal by low-pass filtering the received modulated digital high bit-rate signal. According to the invention, the variation of the average power of the modulated digital high bit-rate signal is effected by a variation of the density of “high” bits according to the low-frequency signal.

  • Patent number: 9231724
    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.

  • Patent number: 8959406
    Abstract: Provided are systems and methods for adaptive, error-tolerant pattern recognition in the transmission of digital data packets, in which an actual data pattern, including several bits, is detected and is compared with a theoretical data pattern; erroneous and/or correctly recognized bits are detected; erroneous and/or correctly recognized bits are added up (in each case); and the error sum (number of the errors) of the added-up erroneous bits is compared with a specifiable and changeable admissible maximum number of errors.

  • Patent number: 8036528
    Abstract: The invention relates to a data transmission unit for high bit-rate optical data signals, in particular, high bit-rate optical data signals with a backplane, which has a line structure connecting several plug-in positions for several receiver or transceiver cards to each other and/or to one or more additional data processing cards, with the cards, each held in one of the plug-in positions and each having at least one input port for a high bit-rate data signal. Each card also has at least one output port, to which the relevant one or more high bit-rate data signals can be fed, and each of these output ports is connected via a serial data line between the plug-in position holding the relevant receiver or transceiver card and an input port of a central selection unit with the relevant input port. The output ports connect serially to the central selection unit.
