Thermal compensation composition of optical fiber connector containing a fiber Bragg grating

摘要

An optical fiber connector embedded with a Bragg grating includes: a ferrule formed with a reception unit for inserting and fixing a temperature compensation connection port from one end, a space unit extended from the reception unit toward inside, and an optical fiber insertion hole penetrating a side surface of the other end along a center of an axial direction from an inclined surface gradually narrowed toward inside of the space unit; the temperature compensation connection port formed with a connection unit contacting with the reception unit of the ferrule, an optical fiber support unit having an outer diameter smaller than an inner diameter of the space unit of the ferrule from the connection unit and protruding to be spaced apart from an inlet of the ferrule by a predetermined distance to form a space for accommodating the Bragg grating and support an optical fiber, and the optical fiber insertion hole penetrating both ends along the center of the axial direction to insert the optical fiber; an optical fiber cable having the optical fiber inserted into the optical fiber insertion hole of the temperature compensation connection port and the optical fiber insertion hole of the ferrule and the Bragg grating placed in the space unit of the ferrule; and a socket, one end of which is fixed to the ferrule, and the other end of which is fixed to an optical fiber cladding of the optical fiber cable.

1. An optical fiber connector embedded with an optical Bragg grating for compensating shift in a reflection center wavelength of the optical Bragg grating, the optical fiber connector comprising:
a ferrule formed with a reception unit at an end of the ferrule for inserting and fixing a temperature compensation connection port from one end, a space unit extended from the reception unit toward inside, and an optical fiber insertion hole penetrating a side surface of the other end along a center of an axial direction from a cone-shaped inclined surface provided at other end of the ferrule opposite to the reception unit so that a corresponding end portion of the space unit gets gradually narrowed toward inside of the space unit so as to guide and insert through optical fiber insertion hole the optical fiber; the temperature compensation connection port formed with a connection unit contacting with the reception unit of the ferrule, an optical fiber support unit having an outer diameter smaller than an inner diameter of the space unit of the ferrule from the connection unit so that a gap is provided between the ferrule and the optical fiber support unit and the optical fiber support unit is enclosed entirely by the ferrule and the connection unit and protruding to be spaced apart from an inlet of the ferrule by a predetermined distance to form a space for accommodating the Bragg grating and support an optical fiber, and an optical fiber insertion hole penetrating both ends of the temperature compensation connection port along the center of the axial direction to insert the optical fiber; and an optical fiber cable having the optical fiber inserted into the optical fiber insertion hole of the temperature compensation connection port and the optical fiber insertion hole of the ferrule and the Bragg grating placed in the space unit of the ferrule.
