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.

Abstract: A method for compensating a reference frequency shift due to an interaction of resonant light provided by a resonant light source with atoms of an atomic beam crossing a resonant microwave cavity between light interaction zones includes toggling a wavelength of the provided resonant light between a main optical pumping transition, OPT1, and an alternate optical pumping transition, OPT2, of the atoms of the atomic beam while a frequency of the microwave probe signal fed into the microwave cavity is modulated with a frequency modulation depth, FMD. The method further includes computing a wavelength modulation compensation error signal, WM-CES depending on the measured signal amplitudes of Ramsey fringes used to control the frequency of the microwave probe signal fed into the microwave cavity.

Abstract: A process for removing skew across a set of at least two clients that are members of a particular trunk, the skew removed from a data path from a first communications system component to a second communications system component. The process using a deskew marker to initiate storage of a set of idle primitives in a FIFO for client member of the particular trunk. Releasing in lockstep, idle primitives for the set of FIFO for the set of client members of the particular trunk after receipt of the final deskew marker. Continuing to route subsequent data for the set of clients for that particular trunk through the set of FIFO for the set of clients for that particular trunk. The data path from the first communications system component to the second communications system component may include traversing a fiber optic network

Abstract: In a method for interrogating at least one optical sensor coupled to an optical path, at least two time-shifted optical signals are fed into the optical path and reflected optical signals of the at least two probe signals created by the at least one optical sensor are detected. Each detected reflected optical signal is assigned to one of the at least one optical sensor and a correct optical frequency is assigned to each detected reflected optical signal. An absolute value or a value range or a change of a value or value range of the parameter to be sensed is determined from the one or more of the following physical conditions: the optical reflection signals, the reflectivity of the at least one optical sensor, and the frequency of each detected optical reflection signal, or from one or more dependencies that link these physical conditions.
