Optical and Unified Noise Figure, and Homodyne Noise Figure
“Noise figure” without additions suggests the properties of Fe, i.e. SNR degradation factor in linear system with 2 RX quadratures (and preferably Gaussian noise).

OSA: Characterization of Optical Amplifier Gain and Noise Figure
The applicable models are equipped as standard with an optical amplifier analysis function (EDFA-NF) that automatically calculates the gain and noise figure (NF) of the optical amplifier from the input and
Consistent optical and electrical noise figure
The noise figure is the factor by which the signal-to-noise ratio is degraded from input to output of a device. The optimum noise figure of an electrical amplifier is Fe=1 and the optimum traditional noise
OSA: Optical Amplifier (EDFA) Measurement Guide
Optical amplifiers are primarily evaluated by GAIN and NF (noise figure). The Yokogawa OSAs offers a built-in EDFA-NF analysis function to easily measure these characteristics. Simply measure the

Abstract Electrical measurements of the noise figure of a fiber optical parametric amplifier are presented and compared with optical measurements.
Optical and Unified Noise Figure, and Homodyne Noise Figure
Traditional optical noise figure Fpnf was defined in 1990ies, for optical direct detection receivers (DD RX). Problematic aspects, in conflict with electrical NF: Optical signals have in-phase and quadrature
Theory and Measurement Techniques for the Noise Figure of Optical
Abstract The theoretical basis for the noise figure of optical amplifiers is reviewed, and a consistent approach to determining the noise figure of cascaded components is developed. It is
Frequency-resolved noise figure measurements of phase (in)sensitive
Abstract: We measure the frequency-resolved noise figure of fiber optical parametric amplifiers both in phase-insensitive and phase-sensitive modes in the frequency range from 0.03 to 3 GHz. We also
Optical Signal to Noise Ratio (OSNR)
Optical Signal to Noise Ratio (OSNR) is the measure of the ratio of signal power to noise power in an optical channel. OSNR is important because it suggests a degree of impairment when the optical
