Abstract: The proposed invention is in the area of managing resources in optical transport networks, for example in the area of in-operation media channel format and spectrum management. For this purpose, the type of Media Channel Format is determined for each of a plurality of candidate paths, wherein each candidate path connects a pair of nodes in an optical transport network. Then, the expected weight describing traffic volume of each of the candidate paths is determined, and a spectrum share is assigned to each link of each of the candidate paths based on the determined Media Channel Formats and determined weights. In this way, spectrum shares assigned to different links and candidate paths can be used for efficiently assigning a band spectrum to each of the Media Channel Formats of the candidate paths.

Abstract: A method of distinguishing whether a detected change in reflected power in an optical time domain reflectometer (OTDR) measurement carried out in a fiber optic transmission system (16) using an OTDR is caused by a an event causing actual attenuation or a change in a mode field diameter, comprising the steps of emitting a succession of first sampling light pulses of a first wavelength into the fiber optic transmission system (16) while a pumping signal with a second wavelength is emitted into the fiber optic transmission system (16), and measuring a first OTDR trace (34') resulting from the reflection of the first sampling light pulses in the fiber optic transmission system (16), such that the first sampling light pulses and their reflections interact with the pumping signal via stimulated Raman scattering. The method further comprises a step (36) of determining, based at least on information extracted from the first OTDR trace (34'), whether the detected change is mainly due to an event causing actual attenuation or to a change in the mode field diameter in the fiber optic transmission system (16).

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 (OC1) of a WDM-signal. This channel signal (OC1) is on-off-modulated by a modulation test signal (MT1) having a predetermined lower frequency and is generating a channel test signal (OT1). This channel test signal (OT1) is combined with other optical channels (OC2-OCn) to the WDM-signal (WS) and transmitted via said path. At a start node (1) or a downstream node (3, 5) a measurement signal (EMI, EM3) is derived from the complete WDM-signal (WS) without wavelength de-multiplexing. The measurement signal (EM1, EM3) is compared with a correlation signal (MC1) and an obtained power level (PC1) is used to adjust the channel power (PC1, PC2, PC3) to achieve predetermined target power values (PC1-PC4) at different power monitoring points (19, 40, 41, 58). The adjustment step is repeated for all downstream nodes (3, 5) and all further channel signals (OC2-OCn).
