Abstract: Disclosed herein is a method of transmitting a data stream from a first location to a second location through an optical network, as well as a corresponding performance monitoring unit, a transmitting arrangement and a receiving arrangement. The method comprises the steps of transmitting said data stream from said first location to said second location along a working path, wherein said data stream is transmitted in the form of a super channel comprising a number of n wavelengths within a predefined reserved wavelength range, monitoring the performance of the transmission based on the super channel signal received at said second location, and in case the performance is observed to drop below a predetermined performance threshold, unburdening the super channel from a part of said data stream while maintaining the reserved wavelength range for said super channel, by redirecting said part of the data stream for transmittal along at least one restoration path connecting said first and second locations, and transmitting the remainder of said data stream within the super channel on a number of wavelengths that is less than n, and/or with a reduced transmission rate for at least some of the wavelengths in said super channel.

Abstract: Disclosed herein is a method of encoding and/or decoding data for optical data transmission along a transmission link, as well as corresponding transmitters and receivers. The data is encoded based on an adaptive constellation diagram in a 2-D plane, said constellation diagram including a first and a second pair of symbols, wherein the symbols of the first pair of symbols are located at opposite sides of the origin of the 2-D plane at a first distance di from each other, and wherein the symbols of the second pair of symbols are located at opposite sides of the origin of the 2-D plane at a second distance d2 from each other. The method comprises a step of adapting the constellation diagram by varying the ratio of the first and second distances d1, d2 such as to minimize or nearly minimize a bit error rate in the transmitted data.

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).
