Embodiment

[0028] Such as figure 1 , figure 2 As shown, a SC quick-connect ceramic ferrule, the main body 2 of the ceramic ferrule is cylindrical; wherein, the inner hole 3 of the other end of the ceramic ferrule is provided with a conical groove 1, and the tapered end The angle between the oblique length of the head and the axis of the ferrule is 30°. The length of the ceramic ferrule is 10.50±0.05mm, the inner diameter is between 0.1253-0.1263mm, the outer diameter is 2.4990±0.0005mm, the concentricity is not greater than 1μm, and the cylinder is a 2.0mm wide positioning groove;

[0029] It can be seen from the above technical scheme of an SC quick-connect ceramic ferrule of the present invention that: through the conical grooves 1 at 3 places in the inner hole of one end of the ceramic ferrule, 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 trans...

Abstract

The invention discloses a SC fast-connecting ceramic ferrule which is assembled in the center of an optical fiber connector. The body of the ceramic ferrule is cylinder-shaped. One section of one end of the ceramic ferrule is shaped as a conical end. The conical end is shaped as a circular truncated cone. A conical groove is arranged at an inner hole of the other end of the ceramic ferrule. The included angle between the inclined length of the conical end and the axis of the ceramic ferrule is 30 degrees. The cylinder has a positioning groove which is 2.0mm wide. The length of the ceramic ferrule is (10.50+ / -0.05)mm, the inner diameter is between 0.1253mm and 0.1263mm, the outer diameter is (2.4990+ / -0.0005)mm, and the concentricity is not larger than 1 micron. The body of the ceramic ferrule is designed into a cylinder, one section of one end of the ceramic ferrule is designed into a conical end, the conical end is shaped as a circular truncated cone, and the conical groove is arranged at the inner hole of the other end, thus achieving the purposes of small optical coupling loss, accurate connection and positioning, convenient use, beautiful appearance, stable performance, greatly-improved light signal transmission speed and longer service life.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to an SC quick-connect ceramic ferrule. Background technique [0002] In recent years, with the rapid development of information technology, the Internet has been popularized and used rapidly. As of December 2011, the global Internet users have reached 1.8 billion. With the rapid popularization of the Internet, people's requirements for Internet speed are also increasing. , optical communication technology, as a communication technology different from traditional analog signals, has developed rapidly with its high speed and large capacity. At present, optical fiber communication has become the main transmission means of modern communication networks. [0003] Optical communication technology is a communication method that uses light as the medium, optical fiber as the medium, and uses light waves to transmit information in the optical fiber. As the light transmitted as a s...
