Abstract: High speed networks face several challenges in order to meet desired Quality of Service (QOS). In order to increase network speed with significant reduction in Bit Error Rate (BER), new design techniques have to be deployed in high speed networks. In this paper, basics of high speed networks along with Dense Wavelength Division Multiplexing(DWDM) network issues and challenges have been discussed. Modulation schemes and amplifier configurations are also summarized. Investigations on applicability of modulation schemes for DWDM network architecture have been performed with various hybrid optical amplifier configurations. The link configuration consists of 56 channels at speed of 15Gbps.It is observed that Non Return to Zero (NRZ) scheme gives better performance in terms of Quality-factor (Q-f) and BER. The network parameters are further improved using various hybrid optical amplifier configurations. It is observed that NRZ scheme with Erbium Doped Fiber Amplifier (EDFA) hybrid amplifier configuration has improved the quality factorof system as compared to other hybrid amplifier configurations.
Keywords: Amplifier, Bit Error Rate (BER), Modulation, Multiplexing, Quality-factor (Q-f).
