Abstract
A pigtail-type optical receptacle includes a ferrule, an optical fiber, a protective member, a sleeve, and a holder. The ferrule has a through-hole extending in an axial direction. The optical fiber is held by the ferrule in a state of being inserted into the through-hole and extends outside the ferrule from a rear end side of the ferrule. The protective member covers a portion of the optical fiber extending outside the ferrule. The sleeve engages an outer surface of the ferrule. The through-hole includes a first region and a second region. The second region is disposed rearward of the first region. The width in an orthogonal direction orthogonal to the axial direction of the through-hole in the second region widens toward the rear end side of the ferrule. The holder holds a portion of the outer surface of the ferrule rearward of the first region.
