Simulation of 64 x 2.5 Gb/s WDM transmission over 1056 km of standard single-mode fiber using gain-flattened silica-based EDFAs

Using computer simulation, we have shown the viability of 64 2.5-Gb/s wavelength-division multiplexing (WDM) channel transmission over 1056 km of standard single-mode fiber (SMF) using gain-flattened silica-based erbium-doped fiber amplifiers (EDFAs), long-period fiber grating filters, and dispersion compensation.
