    摘要: The invention relates to a method of swept sine wave OTDR (optical time domain reflectometry) measurement, wherein a data signal (5), which carries payload data, is modulated by a sine wave signal (7) on top of the payload data of the data signal (5), thus generating a modulated optical output signal (12), wherein the sine wave signal (7) is swept within a defined frequency range, characterized in that the modulation amplitude of the modulated optical output signal (12) is monitored, and the amplitude of the sine wave signal (7) is controlled in dependence of the modulation amplitude of the modulated optical output signal (12) monitored during the present frequency sweep such that the monitored modulation amplitude of the modulated optical output signal (12) matches a predefined value distribution over the whole frequency range. The inventive method allows an accurate calibration of an OTDR measurement equipment without an interruption of the data traffic.

    摘要: Proposed is a method of monitoring a connectivity of an optical network terminal to an optical output port of a remote node in an optical access network. A network analyzer transmits a control signal that indicates a request for modulating a power level of an optical downstream signal at a dedicated optical output port of a remote node. A controller receives the control signal from the network analyzer and transmits an output control signal indicating the output port to said remote node. The remote node receives the output control signal and activates an optical modulation device present at the output port. An optical network terminal indicates reception levels of a received downstream signal for successive time instances. The network analyzer retrieves reception level data and furthermore derives a potential connection of the optical network terminal to the dedicated output port.
