摘要： The invention relates to a method for maintaining the compatibility of legacy receivers in network termination units of an optical distributing network structure, especially in a passive optical network, when in the distributing network structure advanced receivers with a multiple of the data rate of the legacy receivers shall be operated too, in which signals for the advanced receivers are transmitted on the same wavelength and using the same physical paths as signals for the legacy receivers, in which, while transmitting signals for the advanced receivers at the same time also signals for the legacy receivers are transmitted, and in which the amplitude of the signals for the advanced receivers compared to the amplitude of the signals for the legacy receivers are chosen such that the signals for the advanced receivers do not block the legacy receivers in the receipt of the signals intended for them.

摘要： A method for monitoring a passive optical network (1), PON, having a tree-like structure with a main line (3) and at least two branches (6.1 to 6.3), comprising: transmitting a wake-up signal (10) from the main line (3) to at least two monitoring units (DPM1 to DPM3) arranged in the at least two branches (6.1 to 6.3), in each of the monitoring units (DPM1 to DPM3), detecting the wake-up signal (10) and transmitting a response signal (A, B, C) back to the main line (3), each of the monitoring units (DPM1 to DPM3) generating a pre-defined time delay (ΔtA to ΔtC) between the detection of the wake-up signal (10) and the start of the transmission of the response signal (A, B, C), and receiving the response signals (A, B, C) at the main line (3), the receiving times (R1 to R3) of the response signals (A, B, C) being different from each other, the difference between the receiving times (R1 to R3) being adjusted by the pre-defined time delays (ΔtA to ΔtC) of the monitoring units (DPM1 to DPM3).
