AbstractIn this paper we have study the performance of different optical amplifiers (Erbium doped amplifier (EDFA), RAMAN amplifier, and semiconductor optical amplifier (SOA)) for 80 channels wavelength division multiplexing (WDM) system with the data rate at 10 Gbps data rate for the transmission distance of 280 km After getting the results of these amplifiers the performance of these has to be compared The Q-factor values achieved better in EDFA as compared to SOA and RAMAN. While the BER getting good in SOA as compared with other amplifiers but in EDFA after 200 km it goes saturated, the Power achieved at the power estimator is getting better in EDFA optical amplifier while in other amplifier it achieved negative. At the end it is also study the Power with frequency in THz and the Eye Diagram of such amplifiers results.

Currently it is not possible to create a fully optical communication system without a software tool which simulates an optical communication line in real conditions prior to its construction. The aim of this article is to establish a comparison between the EDFA (erbium doped fibre amplifier) and SOA (semiconductor optical amplifier) optical amplifiers in the WDM (wavelength division multiplexing) system. The system contains a four-channel WDM with speed of 10 Gbps and optical fibre with length of 80 km. Simulations are conducted in the programme environment “OptSim.” The quality of the optical communication system is evaluated by the BER (bit error rate) and Q-factor for individual wavelengths, namely, of 1558 nm and 1562 nm, which are within the C-band.

Abstract Free space optics (FSO) is well-competent and premier technology to cater the high speed services in different geographical areas such as hilly areas and inter building network. In this paper, we successfully demonstrated the spectrum sliced wavelength division multiplexed FSO system. In order to make system bandwidth efficient, frequency spacing of 75 GHz is taken among the wavelength division multiplexing (WDM) channels. Carrier spectrum broadening is achieved for spectrum slicing through the nonlinearity called self-phase modulation. Moreover, requirement of multiple laser sources is eliminated. However, in conventional WDM systems, n numbers of lasers are needed to generate n WDM channels. To strengthen the signal in this FSO system, three optical amplifiers are scrutinized such as erbium-doped fiber amplifier (EDFA), semiconductor optical amplifier (SOA) and Raman amplifier in terms of Q-factor and bit error rate (BER). Results revealed that EDFA is best amplifier in proposed SS-WDM-FSO system.
