Theoretical Study on Hybrid Amplification of 32-Channels DWDM in Optical Parametric Amplifiers

Abstract

With the increasing demand for greater quality of transferred data, the optical cable lines are reaching their limits of transfer capacities. The alternative for more effective usage is by introducing the Dense Wavelength Division Multiplexing (DWDM) integrated with optical amplifier to optimize the output signal. This study was performed theoretically with an assistance of OptiSystem 9.0 simulation software to develop higher transfer speed of 32 channels DWDM network system by employing hybrid optical amplifiers. Three types of optical amplifiers had been introduced such as Erbium Doped Fiber Amplifier (EDFA), Semiconductor Optical Amplifier (SOA) and Dynamic RAMAN amplifier. The optimum performance of DWDM system was obtained by employed hybrid EDFA-Raman amplifier which resulted the best transmission signal received with maximum Qfactor=43.0579 a.u. The hybrid EDFA-Raman produced better stability than EDFA-SOA where the received signals were only fluctuated within ±3.73 a.u. In comparison with other types of configuration, namely EDFA-SOA and
RAMAN-SOA; the value of maximum Q-factor experienced about 50% of increment. In conclusion, the development of high performance and excellent stability of 32- channels DWDM optical network system can be achieved by introduced hybrid amplifier of EDFA-RAMAN.
