Ademas, existen tres configuraciones para los amplificadores: Booster, en la cual el EDFA se situa a continuacion de una fuente optica y antes de la fibra principal; Inline, que situa el amplificador entre los span de fibra optica; y pre-amplificacion, en la que EDFA se ubica inmediatamente antes del receptor [9].
Achieving such a high capacity, even with extremely wide bandwidth EDFAs, requires efficient use of the bandwidth at a level that is close to the Shannon limit, the fundamental spectral efficiency limit of optical communications.
La configuracion tradicional con amplificacion EDFA en ausencia de inyeccion Raman presenta dos etapas de amplificadores EDFA, una fibra DCF y una fibra principal SSMF-28.
In this study, modeling is performed by using Sugeno-type FIS to model the pump laser current (PLC) on EDFA. Fig.
After 10 km SMF-28 transmission, in order to obtain the optimal output, which requires that the input power into the PD cannot be too low, a following erbium-doped fiber amplifier (EDFA) was utilized to compensate the attenuation of the fiber.
In optical communication the EDFA fibre amplifiers, SOA semiconductor amplifiers, or amplifiers based on the Raman effect are the most widely used ones [2-4].
