Abstract: We show that an earlier proposed efficient dispersion compensating fiber (DCF) design based on a coaxial fiber structure can also provide dispersion compensation over a broad wavelength region matching that of an erbium doped fiber amplifier gain spectrum. The design can provide dispersion coefficient almost double those of existing DCF designs. Due to the basic nature of the dispersion curve of this design, the total link dispersion cannot only be compensated but also be flattened. !13
