Title: Optical fiber connector and its manufacture
Inventor: TSUKADA KIYOTAKA
IPC: G02B6/36
Filed: 1985-03-27
Abstract: PURPOSE:To obtain an optical fiber connector which has high size precision, small wear resistance, and a small coefficient of heat expansion and hardly causes optical fibers to shift in axial position by filling resin in a silicon carbide sintered body which has open pores. CONSTITUTION:The optical fiber connector needs to use the silicon carbide sinter which is a porous body with open pores and sintered in a specific shape without any substantial shrinkage as a base material. Namely, the silicon carbide sinter which shrinks into the sinter is preferable in terms of strength and wear resistance, but the size of the sinter manufactured by a sintering method which causes shrinkage is affected greatly by the density of a raw molding body and the quantity of shrinkage during sintering, so the shrinkage during the sintering should be uniform so as to manufacture a sinter having superior size precision. It is important to obtain a raw molding body which has uniform density so as to make the shrinkage uniform, but it is extremely difficult to obtain the raw molding body with the uniform density mentioned above and it is difficult to manufacture the optical fiber connector by baking and shrinking the sinter with superior size precision.
