Abstract
An optical receptacle includes a fiber stub having an optical fiber with a core and cladding, a ferrule with a through-hole fixing the optical fiber, and a bonding agent fixing the optical fiber in the ferrule, and a holder holding the fiber stub. The optical fiber is disposed inside the through-hole over an entire region of the optical fiber, and includes a portion in which a core diameter and a fiber outer diameter decrease gradually toward an end surface of the ferrule on a side opposite to a side to be optically connected to a plug ferrule. The bonding agent is filled into a space between the optical fiber and an inner wall of the through-hole.
