An optical receptacle includes: a fiber stub having a ferrule and an
optical fiber in a through-hole of the ferrule; a holder to which an rear
end of the fiber stub is fixed; and a sleeve for holding a plug ferrule
in front of the fiber stub; wherein a grip ring is provided on an outer
side face in which the fiber stub and the sleeve are overlapped to each
other, whereby attaining the shortened optical receptacle, and improving
connection loss due to tilting of the plug ferrule, and obtaining good
repeatability of the connection loss.
