Dispersion Compensating Fibre (DCF)
YOFC dispersion compensating fibre is specially developed through proprietary PCVD-based technology. Taking advantages of PCVD process, YOFC is 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 working wavelength. Customized fibres with special center wavelength and dispersion are available.
