Abstract
The invention refers a method and an arrangement for channel set up in an optical network. An optical signal path is configured for a certain optical channel signal (OC) of a WDM-signal. This channel signal (OC) is on-off-modulated by a modulation test signal (MT) having a predetermined lower frequency and is generating a channel test signal (OT). This channel test signal (OT) is combined with other optical channels (OC-OCn) to the WDM-signal (WS) and transmitted via said path. At a start node () or a downstream node () a measurement signal (EMI, EM) is derived from the complete WDM-signal (WS) without wavelength de-multiplexing. The measurement signal (EMI, EM) is compared with a correlation signal (MC) and an obtained power level (PC) is used to adjust the channel power (PC, PC, PC) to achieve predetermined target power values (PC-PC) at different power monitoring points (). The adjustment step is repeated for all downstream nodes () and all further channel signals (OC-OCn).
