Abstract
A dispersion compensation scheme using the minimum number of cascaded fibre Bragg gratings (FBGs) is proposed for the transmission of 20â¯Gbps signal in 24 Wavelength Division Multiplexed (WDM) channels with a 0.4â¯nm channel spacing. The present work shows that four chirped FBGs (CFBGs) in cascade are sufficient to compensate the dispersion accumulated over 100â¯km of conventional fibre. The parameters of the CFBGs are optimized to obtain maximum quality factor for all the channels. The proposed setup is effective for simultaneous dispersion compensation in a WDM transmission system.
