Open EDFA gain spectrum dataset and its applications in data-driven EDFA gain modeling

Journal of Optical Communications and Networking, 2023
Optical networks satisfy high bandwidth and low latency requirements for telecommunication networks and data center interconnection. To improve network resource utilization, machine learning (ML) is used to accurately model optical amplifiers such as erbium-doped fiber amplifiers (EDFAs), which impact end-to-end system performance such as quality of ...

Decreasing EDFA transients by power shaping

Optical Switching and Networking, 2008
Multi-wavelength optical networks make extensive use of erbium-doped optical amplifiers (EDFAs) to offset the effects of fiber attenuation and signal power splitting. As optical networking moves towards burst and packet switching, the effects of changes of optical power levels on one wavelength, or channel, can have an impact on the behavior of other ...

Three-stage six-pass EDFA preamplifier design and EDFA parameters’ optimization

Optical and Quantum Electronics, 2021
In this study, three-stage six-pass erbium doped fiber amplifier (EDFA) is performed. The mathematical model to characterize this proposed EDFA are also developed. During the design process, EDFA's input signal wavelengths, EDF lengths and pump powers are optimized.

S-EDFA and R-EDFA polarization properties comparison

Optics Communications, 2005
Experimental results on the behavior of the polarization state of the amplified optical signal for two configurations of erbium doped fiber amplifier: single pass erbium doped fiber amplifier (S-EDFA) and reflective erbium doped fiber amplifier (R-EDFA) employing a circulator and a faraday rotator mirror (FRM) are reported in this paper.

Noise measurements in EDFAs

Conference on Optical Fiber Communication, 1994
We propose a new parameter to describe the noise performance of erbium-doped fiber amplifiers (EDFAs). ft is based on the fact that the noise of a laser amplified by an EDFA is very similar (formally and substantially) to the noise of a laser with a higher relative intensity noise (RIN).

Theoretical analysis, optimization, and experimental evaluation of dual function DP R-EDFA

Journal of Russian Laser Research, 2007
A simple rate-equation model of double pass (DP), remotely-pumped Erbium-doped fiber amplifier (R-EDFA) is developed based on the Giles-and-Desurvire (1991) model of a single pass (SP) EDFA.

Gain peaking in EDFAs

Conference on Optical Fiber Communication, 1994
In long-haul communications, erbium-doped fiber amplifiers (EDFAs) operate at a particular wavelength to produce the optimal level of dispersion. The gain spectrum of the ions can be used to filter the accumulated amplified spontaneous emission in such a system.1 To optimally use this autofiltering, the gain-peak wavelength (GPW) of the chain must ...

Broadband EDFA With Flat Gain Response

Conference on Lasers and Electro-Optics Europe, 1996
Dense WDM techniques in lightwave networks increase transmission capacity and improve system flexibility. Gain flatness of conventional EDFAs limits the number of WDM channels. Several techniques1,2 for EDFA gain equalization have been investigated, but with various shortcomings.
