| Abstract | ||||
| This paper presents high transmission bit rate based on both bidirectional erbium doped fiber amplifiers (EDFAs) and acousto-optic filters using different modulation coding techniques. The performance parameters such as gain flatness, Quality factor, bit error rate, output power, gain with and without acousto-optic filters with EDFA length variation, core radius, pumping power, pumping wavelength, ion density, doping radius, numerical aperture and ambient temperature can be measured. The optimum values for the maximum gain flatness can be obtained with the best modulation format and different number of channels. | ||||
