Dispersion Compensating Fibre (DCF)

Idealphotonics dispersion compensating fibre is specially developed through proprietary PCVD-based technology. Taking advantages of PCVD process, We are able to manufacture complex index-profile shapes accuratelly, therefore, to get the optimized products with the best compromise between insertion loss and residual dispersion over the compensated operating wavelength. Customized fibres with special center wavelength and dispersion are available.
