  • Structure of an input end of an optical fiber
    Patent number: 9964706
    Abstract: The present invention discloses a structure of an input end of an optical fiber, comprising a first optical fiber and a second optical fiber; wherein the first optical fiber and the second optical fiber are coaxial, one end of the first optical fiber is used to receive light beam, and the other end of the first optical fiber is engaged with the second optical fiber; wherein the first optical fiber comprises a fiber core and a first cladding; the second optical fiber comprises a fiber core and a first cladding; wherein a diameter of the first cladding of the first optical fiber is larger than a diameter of the first cladding of the second optical fiber and a difference between them is larger than a first preset threshold; wherein a diameter of the fiber core of the first optical fiber is smaller than or equal to a diameter of the fiber core of the second optical fiber and a difference between them is smaller than a second preset threshold.
