The need for high-speed data transmission has augmented the demand for all-optical amplifiers in dense wavelength division multiplexing (DWDM) systems. In all-optical amplifiers, there is no constraint to convert an input optical signal to electrical and again back to optical signal; hence are very efficient when employed in DWDM systems. In modern high capacity optical communication, there is need for all-optical amplifiers with higher gain. In this paper, the performance optimization of all-optical Erbium–Ytterbium (Er–Yb) co-doped fibre amplifier has been done for a 100-channel super-dense wavelength division multiplexing (SD-WDM) system over a wavelength range of 1525–1625 nm at a reduced channel spacing of 0.2 nm. The EYDFA amplifier reported with a maximum gain of approximately 45 dB for a flat band range has proved to be a good choice for achieving high and flat gain for huge and fast data transmission. The results in terms of lower gain variation ratios (GVR) of 0.03 and 0.16 have been attained as a function of channel wavelengths and input powers, respectively, with good Quality-factor of 6.6. The boosted gain, reduced GVR and acceptable Quality-factor make EYDFA amplifier superior to other amplifiers for long-haul applications. |
