Dual concentric core dispersion compensating fibre optimised for WDM application
03 February 2005
A dual concentric core fibre exhibiting a chromatic dispersion coefficient around -350 ps/(nm km) is used in a dispersion compensating module designed for WDM application. The optimised length ratio is larger than 20 and the residual chromatic dispersion is measured at 0.4 ps/mm km) in the C-band.
