Fiber optic connector having radio frequency identficiation tag and optical fiber connection device
View Patent ↗A fiber optic connector having a radio frequency identification tag and an optical fiber connection device are disclosed in the embodiments of the present invention. The fiber optic connector comprises: a housing ( 1 ); a tail sleeve ( 4 ) partly inserted in the housing from a first end of the housing and configured to fix an end of an optical fiber cable ( 20 ); a tag receiving portion ( 5 ) 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 ( 10 ) is disposed; and an electromagnetism restriction part ( 15 ) 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. The adverse influence of metal material in the fiber optic connector on the read performance of the radio frequency identification tag may be eliminated by disposing the electromagnetism restriction part between the metal holding tube and the radio frequency identification tag.

a spring member having two ends abutting against the fixation tube and an inner wall of the housing between the fixation tube and the inner wall of the housing, respectively.
8. The fiber optic connector of claim 7 , further comprising a stress relief boot fitted over the tail sleeve, wherein the optical fiber cable passes through the stress relief boot and is fixed to the tail sleeve.
9. The fiber optic connector of claim 7 , wherein the housing comprises a first housing for connecting to the optical fiber cable and a second housing for mounting the fiber ferrule, wherein the first housing and the second housing are detachably assembled together in a snap manner, and the tag receiving portion is formed in the first housing.
10. An optical fiber connection device, comprising:
the fiber optic connector according to claim 1 ;
an adaptor in which the fiber optic connector is inserted to be coupled to a mating connector inserted in the adaptor;
a support frame to which the adaptor is mounted; and
a radio frequency read-write antenna mounted to the support frame.
11. 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 chamber having 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 chamber of the tag receiving portion through the at least one opening, and
wherein an elastic tongue portion is formed on a sidewall of the tag receiving portion at one of the at least one opening, and a block protrusion is formed on the elastic tongue portion.
12. The fiber optic connector of claim 11 , wherein the electromagnetism restriction part is disposed in the tag receiving portion.
13. The fiber optic connector of claim 11 , wherein the electromagnetism restriction part covers at least a portion of an outside of the tail sleeve.
14. The fiber optic connector of claim 11 , wherein the electromagnetism restriction part comprises a ferrite sheet.
