Abstract

The invention discloses a large-aperture ceramic ferrule, which is installed in the center of an optical fiber connector and used in conjunction with a metal seat. The main body of the ceramic ferrule is in the shape of a cylinder; one end of the ceramic ferrule has a tapered end; The tapered end is conical; the length of the ceramic ferrule is 2.5±0.05mm, the inner diameter is 0.5±0.02mm, the outer diameter is 2.499±0.0005mm, and the concentricity is not greater than 1μm; the other end of the ceramic ferrule A conical groove is provided at the inner hole of the head. By designing one section of one end of the ceramic ferrule as a tapered end, the tapered end is in the shape of a truncated cone, and the inner hole of the other end is provided with a conical groove, so that the optical coupling loss of the ferrule is small, The connection and positioning are accurate, easy to use, beautiful in appearance, stable in performance, and can greatly improve the transmission speed of optical signals and prolong the service life.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to a large-aperture ceramic ferrule. Background technique [0002] Fiber optic connectors are used for the connection of optical fibers. During use, the optical path must be smooth and the signal loss is small; in terms of structure, the connectors are required to have high coaxiality, smooth surface, moderate pulling force, easy installation and durability. To meet the above requirements, the connector ferrule is a key part. Practice and research have shown that bushings and ferrules made of metal materials are insufficient in terms of wear resistance, temperature stability, and corrosion resistance. At present, ferrules in optical fiber communication connectors and adapters produced at home and abroad are widely made of zirconia ceramics, and their shapes are cylindrical spherical polishing and flat polishing. This kind of ferrule has too large optical coupling alignme...
