In communication products, ceramic structures can be used to manufacture antennas, waveguides, filters and other components.

Fiber optic ceramic core

Ceramic core made of zirconia material has the following excellent properties:
Good coaxiality and dimensional accuracy, small fiber docking error;
High strength, wear resistance, aging resistance, long life;
The thermal expansion coefficient of the material is small, and the environmental adaptability is strong.
Low insertion loss and return loss, high insertion and removal times;

Electronic ceramic case

Long distance transmission of optical communication requires airtight packaging, and electronic ceramic shell is the preferred material for airtight packaging. It is encapsulated with multi-layer ceramic insulator shell and adopts multi-layer co-fired ceramic insulation structure to provide electrical signal transmission channel and optical coupling interface for the device, provide mechanical support and airtight protection, and solve the interconnection between chip and external circuit. Compared with metal materials, electronic ceramic shell has high temperature resistance, corrosion resistance, good moisture resistance, and good thermal properties such as thermal expansion rate and thermal conductivity, high mechanical strength, chemical stability and other advantages, excellent comprehensive performance.
