Embodiment

[0020] Such as figure 1 , figure 2 with image 3 As shown, a SC-APC single-mode ceramic ferrule is installed in the center of the optical fiber connector and used in conjunction with the metal seat 1. The main body 2 of the ceramic ferrule is cylindrical; one end of the ceramic ferrule is conical Shaped end 3; the tapered end 3 is in the shape of a truncated cone. Wherein, the inner hole 4 of the other end of the ceramic ferrule is provided with a conical groove 5, and the angle between the oblique length of the conical end and the axis of the ferrule is 30°±2°. The length of the ceramic ferrule is 10.50±0.05mm, the inner diameter is between 0.125-0.126mm, the outer diameter is 2.4990±0.0005mm, and the concentricity is not greater than 1 μm.

[0021] When a kind of SC-APC single-mode ceramic ferrule of the present invention is installed, as image 3 As shown, one end of the ceramic ferrule provided with a tapered end 3 is placed in the center of the metal seat 1, and the ...

Abstract

The invention discloses an SC-APC single-mode 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 is tapered end; the tapered end is conical; the inner hole of the other end of the ceramic ferrule is provided with a conical groove; the angle between the oblique length of the tapered end and the axis of the ceramic ferrule is 30°±2°; the length of the ceramic ferrule is 10.50±0.05mm, the inner diameter is between 0.125-0.126mm, the outer diameter is 2.4990±0.0005mm, and the concentricity is not greater than 1μm. By designing the main body of the ceramic ferrule into a cylindrical shape, one end of the ceramic ferrule is designed as a conical end, the conical end is in the shape of a cone, and the inner hole of the other end is provided with a conical The groove achieves the purpose of small optical coupling loss of the ferrule, accurate connection positioning, convenient use, beautiful appearance, stable 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 an SC-APC single-mode ceramic ferrule. 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...
