Paper Abstract

Filters and isolators placed within the EDFA's can be used to increase the gain , and decrease the noise figure. By use of an accurate model the placement of the filters and isolators are optimized. The optimization are performed for situations with pump lasers emittiing at 0.980?m and 1.480?m and signal wavelengths at either the emission cross section peak near 1.530?m or at the silica loss minimum around 1.550?m.
