Four non-zero-dispersion-shifted fibers with almost the same large effective area ( $A_{\text{eff}}$ ) and optimized dispersion properties are realized by novel index profile designing and modified vapor axial deposition and modified chemical vapor deposition processes. An $A_{\text{eff}}$ of greater than $71{\mathrm{\mu m}}^2$ is obtained for the designed fibers. Three of the developed fibers with positive dispersion are improved by reducing the $1550\mathrm{nm}$ dispersion slope from $0.072\mathrm{ps}/{\mathrm{nm}}^2/\mathrm{km}$ to $0.063\mathrm{ps}/{\mathrm{nm}}^2/\mathrm{km}$ or $0.05\mathrm{ps}/{\mathrm{nm}}^2/\mathrm{km}$ , increasing the $1550\mathrm{nm}$ dispersion from $4.972\mathrm{ps}/\mathrm{nm}/\mathrm{km}$ to $5.679\mathrm{ps}/\mathrm{nm}/\mathrm{km}$ or $7.776\mathrm{ps}/\mathrm{nm}/\mathrm{km}$ , and shifting the zero-dispersion wavelength from $1500\mathrm{nm}$ to $1450\mathrm{nm}$ . One of these fibers is in good agreement with G655D and G.656 fibers simultaneously, and another one with G655E and G.656 fibers; both fibers are beneficial to high-bit long-haul dense wavelength division multiplexing systems over S-, C-, and L-bands. The fourth developed fiber with negative dispersion is also improved by reducing the $1550\mathrm{nm}$ dispersion slope from $0.12\mathrm{ps}/{\mathrm{nm}}^2/\mathrm{km}$ to $0.085\mathrm{ps}/{\mathrm{nm}}^2/\mathrm{km}$ , increasing the $1550\mathrm{nm}$ dispersion from $-4\mathrm{ps}/\mathrm{nm}/\mathrm{km}$ to $-6.016\mathrm{ps}/\mathrm{nm}/\mathrm{km}$ , providing facilities for a submarine transmission system. Experimental measurements indicate that the developed fibers all have excellent optical transmission and good macrobending and splice performances.
