PROBLEM TO BE SOLVED: To provide an optical communication sleeve having stable optical characteristics and ferrule holding force. SOLUTION: A cylindrical shape optical communication sleeve 1 has a through-hole 2 to insert a ferrule in an axial direction. A processing cut 3 is formed on an inner peripheral surface 2a of the through-hole 2 in an approximately parallel manner with respect to an axial direction A. COPYRIGHT: (C)2005,JPO&NCIPI
