Summary :

The structural design of a glazed alumina substrate for use in a hybrid IC repeater in the CS-36M submarine cable system is studied. The thickness of the alumina substrate, the thickness of the glaze, and the thermal expansion coefficient of the glass used for the glaze, are theoretically determine for the large (110 mm in diameter) substrate in terms of the load stress when the repeater is installed, the thermal strain when the glaze is formed, and displacement due to lateral pressure. It is found that the desirable thickness of the alumina substrate is approximately 2 mm, the desirable glaze thickness is approximately 65 µm, and the desirable thermal expansion coefficient is (7.77.5)10^-6^-1. A glazed alumina substrate is fabricated on the basis of these structural design parameters, and it is subjected to the mechanical strength test and form test prescribed for the CS-36M submarine cable system. The results prove that the substrate has sufficient mechanical strength and that there is no deformation problem. The glazed alumina substrate developed in this study is applied in a repeater used in the CS-36M submarine cable system and it contributes to the very high reliability of the repeater.
