Description

Clamping device for fiber optic ceramic ferrules

Technical field

The present application relates to the technical field of optical fiber ceramic ferrule production, and in particular to a clamping device suitable for optical fiber ceramic ferrules.

Background technique

Optical fiber ceramic ferrule, also known as ceramic ferrule body, is a precisely aligned cylinder in an optical fiber connector plug with a microhole in the center for fixing optical fibers. The optical fiber connector precisely connects the two end faces of the optical fiber to maximize the coupling of the light energy output from the emitting optical fiber into the receiving optical fiber. It is made of nano-zirconia (ZrO2) material through a series of formulas and processing. It is a high-precision special ceramic component with an aperture and roundness error of 0.5 degrees. The center hole is made by fixing the fiber in the hole. Fiber ceramic ferrules are detachable and classified optical fiber movable connectors on optical connectors, which make the connection and conversion scheduling of optical channels more flexible and can be used for debugging and maintenance of optical communication systems.

The optical fiber ceramic ferrule has a light loss of more than 8% after light transmission testing, which does not meet the standard light loss parameter of 0.25%. Therefore, the end face of the optical fiber ceramic ferrule needs to be optically coated. This coating is for the communication band of 1260nm- 1650nm transmission enhancement coating, after coating, the light transmission can reach more than 99.75% in the 1260-1650nm band.

In related technologies, the optical fiber ceramic ferrule needs to be ultrasonic cleaned before coating. The optical fiber ceramic ferrule is placed into a jig, and then placed together with the jig into an ultrasonic cleaning device for cleaning. During the cleaning process, Ultrasonic waves will cause cavitation reactions and produce larger vibrations. In addition, the alkaline detergent added in the ultrasonic cleaning device is relatively slippery, causing the fiber ceramic ferrule to easily slip out of the fixture during the cleaning process, affecting the cleaning effect. In addition, the cleaning is completed After drying, it is easy for the optical fiber ceramic ferrule to be thrown out of the fixture.

It should be noted that the information disclosed in the above background section is only used to enhance understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to those of ordinary skill in the art.
