This invention relates to a method for manufacturing a non-zero dispersion-shifted single-mode optical fiber preform, as well as the resulting preform and optical fiber. The method includes depositing an inner cladding and a core layer. The inner cladding and multiple core layers are deposited inside a quartz tube using PCVD (Polycarbonyl Variation) technology. The preform is then fused together to form a core rod. The deposited tube is heated and fused together in a fusion lathe to form a core rod containing both the core and inner cladding. The heating and fusion process is adjusted by controlling the axial movement speed and output power of the furnace to regulate the outer diameter and out-of-roundness of the fused core rod. The core rod is then externally deposited with a pure silica cladding using OVD (Optical Variation) technology, or fitted with a pure silica outer tube. Finally, through sintering or fusion processing, a non-zero dispersion-shifted single-mode optical fiber preform is produced. This invention not only ensures the accuracy of the deposition process but also improves the quality of the core rod fusion process, thereby achieving precise core rod manufacturing and further optimizing optical fiber performance.
