Abstract
A sleeve for optical communication and method for manufacture for the sleeve for optical communication, for which withdrawal force for ferrules, which are generally used in the technical field of optical communication, or connection loss between ferrules is a predetermined value, and for which manufacturing steps are reduced so as to allow reduction of manufacturing cost. The invention is made by press-molding ceramic feedstock, which after cold isostatic pressing and sintering are performed thereto, and is made so that an inner circumferential surface, of a through-hole for inserting a ferrule formed on the length-direction of the axis, has a sintered state.
