for WDM signals," Journal of Lightwave Technology, vol.
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.
In this study, modeling is performed by using Sugeno-type FIS to model the pump laser current (PLC) on EDFA
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].

OCP is further connected with a three-port optical circulator ([OC.sub.co]) that is fed into switching arrangement (SA) through an erbium doped fiber amplifier (EDFA
