Abstract

Four non-zero-dispersion-shifted fibers with almost the same large effective area ( $A_{eff}$ ) and optimized dispersion properties are realized by novel index profile designing and modified vapor axial deposition and modified chemical vapor deposition processes. An $A_{eff}$ of greater than $71 {μm}^{2}$ is obtained for the designed fibers. Three of the developed fibers with positive dispersion are improved by reducing the $1550 nm$ dispersion slope from $0.072 ps / {nm}^{2} / km$ to $0.063 ps / {nm}^{2} / km$ or $0.05 ps / {nm}^{2} / km$ , increasing the $1550 nm$ dispersion from $4.972 ps / nm / km$ to $5.679 ps / nm / km$ or $7.776 ps / nm / km$ , and shifting the zero-dispersion wavelength from $1500 nm$ to $1450 nm$ . 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 $1550 nm$ dispersion slope from $0.12 ps / {nm}^{2} / km$ to $0.085 ps / {nm}^{2} / km$ , increasing the $1550 nm$ dispersion from $- 4 ps / nm / km$ to $- 6.016 ps / nm / km$ , 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.
