Dispersion compensation in a 24 × 20 Gbps DWDM system by cascaded chirped FBGs

A dispersion compensation scheme using the minimum number of cascaded fibre Bragg gratings (FBGs) is proposed for the transmission of 20 Gbps signal in 24 Wavelength Division Multiplexed (WDM) channels with a 0.4 nm channel spacing. The present work shows that four chirped FBGs (CFBGs) in cascade ar...

Description
Summary:A dispersion compensation scheme using the minimum number of cascaded fibre Bragg gratings (FBGs) is proposed for the transmission of 20 Gbps signal in 24 Wavelength Division Multiplexed (WDM) channels with a 0.4 nm channel spacing. The present work shows that four chirped FBGs (CFBGs) in cascade are sufficient to compensate the dispersion accumulated over 100 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.
