Abstract
A resin sleeve is used as an optical connection sleevefor optically connecting an optical fiberwith an optical component. A ferrule fixing surfaceprovided on an inner peripheral surface of a ferrule insertion portionof the sleeveis formed to have a multifaceted shape in which a cross section thereof on a plane vertical to an optical axis A thereof has a hexagonal shape. A ferrulecan be positioned and fixed accurately by a tight fit utilizing elastic deformation of resin. An outer peripheral surface of the ferruleand the ferrule fixing surfacecome into line contact with each other, and thus detachability of the ferruleis enhanced. Therefore, an optical fiber ferrule can be held accurately, and the optical connection sleeve having a satisfactory detachability, an optical module using the same and an optical communication module are realized.
