In this paper, we proposed sixteen channel dense-wavelength-divisionmultiplexing (DWDM) optical transmission system using semiconductor optical amplifiers (SOAs). The SOA amplifiers overcome the attenuation effects of transmitted signal in optical communication systems. To overcome attenuation effects, pre-, post (booster) and In-line SOAs techniques are modeled, analyzed and compared for investigating the performance of DWDM system. The proposed system is designed for 10Gbps network using non-return-tozero (NRZ) modulation format with dispersion compensation fiber (DCF) of length 14kms and a single mode fiber (SMF) of length 70kms using Optisystem7.0 simulator. Performance of designed system is explored and compared in terms of eye shape (eye-diagram), Q-factor and bit error rate (BER) by varying the input power (mw) parameter of CW laser source. It is observed that the In-line SOA amplifier provides the best performance as attenuation compensator for proposed optical transmission systems.

Abstract


In this paper, we proposed sixteen channel dense-wavelength-divisionmultiplexing (DWDM) optical transmission system using semiconductor optical amplifiers (SOAs). The SOA amplifiers overcome the attenuation effects of transmitted signal in optical communication systems. To overcome attenuation effects, pre-, post (booster) and In-line SOAs techniques are modeled, analyzed and compared for investigating the performance of DWDM system. The proposed system is designed for 10Gbps network using non-return-tozero (NRZ) modulation format with dispersion compensation fiber (DCF) of length 14kms and a single mode fiber (SMF) of length 70kms using Optisystem7.0 simulator. Performance of designed system is explored and compared in terms of eye shape (eye-diagram), Q-factor and bit error rate (BER) by varying the input power (mw) parameter of CW laser source. It is observed that the In-line SOA amplifier provides the best performance as attenuation compensator for proposed optical transmission systems.
