Abstract In this paper, design of erbium-doped fiber amplifiers (EDFA) based 16 channel wavelength-division multiplexing (WDM) system for different pump powers and input signal levels using counter propagating pumping scheme is reported. Wavelength range between 1548 and 1560 nm in C-band with channel spacing of 0.75 nm at a bit rate of 10 Gbps are used. Input power given to all the channels is taken between −20 and −35 dBm with 3 dBm variation. Pump power levels between 100 and 500 mW at 980 nm wavelength are used. Low gain flatness with high gains and low noise figures are achieved with the proposed scheme.

The effort to build amplified multiwavelength lightwave networks that are large and reconfigurable has raised a host of hard technological challenges, ranging from device-level difficulties to transmission engineering to network-management concerns. Not least of these are the challenges posed by the spectral gain nonuniformities, and the associated multiwavelength noise performance, of such a network's cascaded optical amplifiers. This paper catalogs the research challenges posed by multiwavelength amplification in networks, summarizes the theory underlying them, and describes approaches that are emerging to lessen their ill effects.
