<P>PROBLEM TO BE SOLVED: To provide a crimping type ferrule in which a ferrule is easier to be caulked in order to enable sufficient fixing strength to be obtained without adversely affecting optical signal transmission functions. <P>SOLUTION: A crimping type ferrule 1 has a two-layer structure comprising an external cylinder 11 and an inner cylinder 12, and the Vickers hardness and volume modulus of the inner cylinder 12 are lower than those of the external cylinder 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
