  • Optical Amplifier Noise Factor

    Optical Amplifier Noise Factor

    The noise factor is defined as the unitless ratio of the output noise power of a device to the portion thereof attributable to thermal noise in the input termination at standard noise temperature T0 (usually 290 K). These figures of merit are used to evaluate the performance of an amplifier or a radio receiver, with lower values indicating. The noise factor F of an (electronic or optical) amplifier is a measure of how much excess noise the amplifier adds to the signal. In-line amplifiers: Periodically amplify signal due to fiber attenuation, high G, high Psat. An illustration of the effective gainis given below. Note the presence of a gain peak around 1530nm and a semi-flat gain. Electrical noise figure (NF) is standardized since many decades. Problematic aspects, in conflict with electrical NF: Optical signals have in-phase and quadrature components, like. Noise figure is commonly used in commu-nications systems because it provides a simple method to determine the impact of system noise on sensitivity.
