Abstract
In optical networks containing erbium-doped fibre amplifiers (EDFAs), variable traffic characteristics lead the input power to the amplifier to oscillate and cause fast time-dependent gain fluctuations that can impair transmission of data carried on co-propagating channels. Some of the critical factors that affect the behaviour of an all-optically stabilized EDFA were studied [1], but without differentiating disturbances caused by several network traffic cases. Traffic changes come from add or drop of WDM channels at any network node (WDM routing) or from random interarrival time of data in packet/burst switching transmissions. We evaluate the performance of two lasing wavelengths (above and below the C-band) in a ring-laser clamping configuration to reach minimal EDFA gain-fluctuation and high quality transmission, regardless the input signal condition in WDM routing and packet switched transmissions.
