New dispersion-flattened hybrid optical fiber link composed of medium-dispersion large-effective-area fiber and negative dispersion fiber

A new dispersion-flattened hybrid optical fiber link composed of a medium-dispersion large-effective-area fiber and a negative dispersion fiber is presented. The hybrid fiber link showed a very low and flat dispersion in the C-band. We present a new enlarged-effective-area positive dispersion fiber (EE-PDF) with a medium-dispersion to reduce the dispersion accumulation and a NDF with a negative dispersion slope optimized for dispersion compensation for the EE-PDF. In addition we report on the dispersion and attenuation characteristics of a hybrid optical fiber link composed of these fibers.
