Abstract

This paper describes a novel and efficient method for parameter extraction and characterization of Erbium-doped fiber amplifiers (EDFA). In DWDM systems gain and noise behavior of EDFAs depend on the number and distribution of transmission channels. Hence, characterization of EDFAs for reliability evaluations requires a costly measurement setup of up to 80 or even more wavelength selected laser sources. Our novel method uses photonic transmission simulation to drastically reduce the measuring efforts. Using only a few characteristic measurements with one tunable laser, the gain and noise behavior of amplifiers can be simulated for any number and distribution of transmission channels in DWDM systems. The simulation of the photonic transmission is based on the commercial simulation package WDMTransmissionMaker by VPI systems. We utilize black-box models for fiber amplifiers which can take into account all linear optical effects like e.g. gain-flattening filters or dynamic gain equalizers. The predictions of the simulations for different single-stage as well as double-stage amplifiers comply with the experiments within the measurement accuracies and help to understand new up-coming optical amplifier technologies and to ensure more reliable optical system designs. The measuring effort for qualification and reliability evaluations can be significantly reduced by using the novel characterization method.
