Quality Optimization Based Trend Line for Hybrid Optical Amplifier Configurations in DWDM Transmission Systems.

This paper focuses on optimization of signal quality in DWDM transmission systems with 128x10 channels considering channel spacing of 100GHz. It is well established that Amplified Spontaneous Emission (ASE) and nonlinearities are two main drawbacks in long haul optical fiber communications. Both of them can be mitigated using Hybrid Optical Amplifiers (HOA). In our work we used OptiSytem 13.0 simulator to perform the optimizations of DWDM transmission systems. We considered three different HOA configurations and calculated signal quality with respect to channel input power, minimum log of Bit Error Rate (BER), maximum eye opening factor. Furthermore we plotted the trend line which can be used to predict the performance of long haul optical fiber communications in case of three different hybrid optical amplifiers deployment scenarios. It is found that H3 (EDFA-RAMANOA) configuration covers 128 channels with optimum channel input power of -5dBm for 17.11dB signal quality. Moreover it is substantially evident by the trend lines and eye opening diagrams that the plotted performance comparison results of HOA are in accordance. [ABSTRACT FROM AUTHOR]
