Title:
CERAMIC FERRULE
Document Type and Number:
WIPO Patent Application WO/2013/189053
Kind Code:
A1
Abstract:
The present invention relates to the technical field of preparation of advanced ceramic materials, and meanwhile, to the technical field of optical communications, and 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 a zirconia material is enhanced, precise structure is achieved, reliability of a product is improved effectively, and notable features such as high connecting quality, fine anti-aging performance, high environmental adaptability and the like can be achieved. A field mounted optical fiber connector with the ferrule has the advantages: coaxial abutting of the optical fiber and better surface smoothness than a plastic product can be achieved, the problem that a scraping is easy to be generated by using the plastic material 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.
