Abstract :
Summary form only given. The operation, administration, and maintenance (OAM) of a transport network require the generation, transmission, and detection of OAM signals that are related to each network layer. In the modelled system Gold codes have been applied for transport of the OAM-signals at channels, which have been modulated externally (by Mach-Zehnder modulators) at different modulation levels in order to characterize the influence of the modulation depth. The simulation has shown the feasibility of CDMA for transport of OAM-signals with a bandwidth up to l0-kbit/s per optical carrier in transparent optical networks with minimised distortion of the high speed data stream.
