Paper Abstract

A serious problem facing wavelength division multiplexed (WDM) networks with fiber amplifier cascades is transient cross saturation or gain dynamics of fiber amplifiers. Attention has been focused primarily on circuit-switched scenarios. When the number of WDM channels transmitted through a circuit-switching network varies, channel addition/removal will tend to perturb signals at the surviving channels that share all or part of the route. Even more serious bit error rate deterioration can arise in WDM packet switched burst mode networks. In this contribution we present experimental results demonstrating the effect of fast power transients in erbium-doped fiber amplifiers (EDFAs) on packetized traffic transmitted through a chain of five EDFAs. Traffic of a LAN has been transmitted over one channel, the effect of EDFA cross gain saturation due to the bursteness of the traffic has been observed in a cw channel. The stabilizing effect of gain clamping the first EDFA in the cascade has been investigated.
