Learned Signal-to-Noise Ratio Estimation in Optical Fiber Communication Links
IEEE Photonics Journal, 2022 This paper proposes a signal-to-noise ratio (SNR) estimator based on recurrent neural network (RNN) in optical fiber communication links. The proposed estimator jointly estimates the linear and nonlinear components of the SNR.

Principle and Application of the C-OTDR
Guangtongxin yanjiu, 2022 The traditional Optical Time Domain Reflectometry (OTDR) technology uses back Rayleigh scattering power for fiber detection. In transmission lines with optical amplifier, Erbium-Doped Fiber Amplifiers (EDFA) are mostly used to compensate for the loss of ...

Signal-to-noise ratio in nonlinear optical amplification process [PDF]
SPIE Proceedings, 1990 In this communication, one looks at the influence of the saturation process over the statistical fluctuations (signal to noise ratio) of the optical power at the output of a travelling wave semiconductor optical amplifier (TWOA) . The statistical behaviour of this device is described starting from the photon density matrix equation.

Relationship between axial resolution and signal-to-noise ratio in optical coherence tomography [PDF]
Optics Letters, 2022 In optical coherence tomography (OCT), axial resolution and signal-to-noise ratio (SNR) are typically viewed as uncoupled parameters. We show that this is true only for mirror-like surfaces and that in diffuse scattering samples such as biological tissues there is an inherent coupling between axial resolution and measurement SNR.
