Abstract

The invention discloses a ceramic ferrule with a slot in the middle, 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. Groove; the length of the main body of the ceramic ferrule is 16±0.05mm, and the diameter is 1.599±0.003mm; the length of the semi-cylindrical groove is 7.5±0.05mm; the diameter of the through hole of the main body of the ceramic ferrule is 0.126- 0.127mm; both ends of the ceramic ferrule are provided with conical grooves at the axial through holes, and the diameter of the conical grooves is 0.9±0.05mm. By setting a semi-cylindrical groove in the middle of the main body of the ceramic ferrule, conical grooves are provided at the axial through holes at both ends of the ceramic ferrule, which achieves accurate connection positioning, convenient fiber insertion and installation, and stable performance , and can greatly improve the optical signal transmission speed and facilitate maintenance purposes.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to a ceramic ferrule with a middle slot. Background technique [0002] The fiber optic connector is to precisely butt the two end faces of the optical fiber, so that the optical energy output from the transmitting fiber can be coupled into the receiving fiber to the maximum extent. The ferrule is the core component of this fiber optic connector. Practice and research have shown that the sleeve and ferrule 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. It is a high-precision special ceramic component processed from nano-zirconia materials through a series of formulas. The formed connector is a detachable and classified optical fiber active connector, which makes ...
