The invention relates to the technical field of preparation of advanced ceramic materials and optical communication, in particular to a zirconia-based ceramic ferrule compositely doping with rare earth elements such as yttrium and cerium. By doping the rare earth elements such as yttrium and cerium to the zirconia-based ceramic ferrule, resistance to phase transformation of zirconia materials is enhanced, precise structure is achieved, reliability of products is improved effectively, and high connecting quality, fine anti-aging performance, high environmental adaptability and the like can be achieved. A field mounting optical fiber connector of the ceramic ferrule has the advantages that coaxial abutting of optical fiber and better surface smoothness than plastic products can be achieved, the problem that scrapings are easy to generate by using plastic materials to connect is solved, anti-aging performance is fine, insertion wastage is low after optical fiber abutting, return loss is high, and connecting quality is fine.
