Fiber optic connector having radio frequency identficiation tag and optical fiber connection device

A fiber optic connector having a radio frequency identification tag, comprising:

• a housing;
• a tail sleeve partly inserted in the housing from a first end of the housing and configured to fix an end of an optical fiber cable;
• a tag receiving portion which is formed in a sidewall of the housing, on a radial outside of the tail sleeve, and in which the radio frequency identification tag is disposed;
• and
• an electromagnetism restriction part disposed between the tag receiving portion and the tail sleeve to restrict an electromagnetic influence of the tail sleeve made of a metal material on the radio frequency identification tag,
• wherein the tag receiving portion comprises a substantially cubic chamber extending in the sidewall, and the tag receiving portion has at least one opening in communication with an outside of the fiber optic connector so as to place the radio frequency identification tag into the tag receiving portion through the opening, and
• wherein an elastic tongue portion is formed on a sidewall of the tag receiving portion adjacent to the outside of the fiber optic connector, at one of the at least one opening, and a block protrusion is formed on the tongue portion.
