Abstract
Flat gain with least noise figure (NF) is the backbone feature of super dense wavelength division multiplexing (SD-WDM) system. It indicates the good amplification in terms of high-quality factor, lowest bit error rate, and good rating output power. So, in this paper, we have mainly focused on the characteristics of proposed EDFA-TDFA hybrid optical amplifier (HOA) in terms of flat gain and noise figure for C-Band. Evaluation has done for 400 × 2.455 Gb/s SD-WDM system with channel spacing of 0.8 nm. Moreover, effect of proposed HOA has also observed with displacement of channel wavelength for evaluating the impact of different set of HOAs for analysis the same characteristics.
Highlights
Flat gain is the highly acceptable characteristics for super dense wavelength division multiplexing (SDWDM) system which try to archive with the combinations of different optical amplifiers and hybrid optical amplifiers (HOAs) [1,2]
We have mainly focused on characteristics of proposed erbium-doped fiber amplifiers (EDFAs)-thulium-doped fiber amplifiers (TDFAs) hybrid optical amplifier (HOA) in terms of flat gain and noise figure for C-Band
In this paper to the best of authors knowledge, first time combination of EDFA and TDFA hybrid optical amplifier has been recommended for getting flat gain with insignificant effect of noise figure (NF) for super dense wavelength division multiplexing (SD-WDM) system
Summary
Flat gain is the highly acceptable characteristics for super dense wavelength division multiplexing (SDWDM) system which try to archive with the combinations of different optical amplifiers and hybrid optical amplifiers (HOAs) [1,2]. The combination of EDFA and TDFA is most significance hybrid optical amplifier (HOA) for delivering the flattered gain and banished the effect of fiber nonlinearity [8,9,10]. Multiple pumping has been recommended in the literature [11,12,13] for TDFA to enhance the performance of super multiplexing system in terms of bit error rate, output power, higher gain bandwidth, and noise figure. In this paper to the best of authors knowledge, first time combination of EDFA and TDFA hybrid optical amplifier has been recommended for getting flat gain with insignificant effect of noise figure (NF) for super dense wavelength division multiplexing (SD-WDM) system. The output is come out in terms of modulated signal
