Single optical fiber calibrator 50 comprises the first collimation lens 51 and the first polarization maintaining optical fibre 52.The first polarization maintaining optical fibre 52 is located at the side of the first collimation lens 51 away from double-fiber collimator 20, for emission or reception flashlight.When the first polarization maintaining optical fibre 52 transmits the light time, the first collimation lens 51 collimates for the flashlight by the first polarization maintaining optical fibre 52 emissions.
Double-fiber collimator 20 comprises the second sleeve pipe 23, the second angle of wedge sheet 24, the second collimation lens 25, pumping optical fiber 21 and double clad polarization maintaining optical fibre 22.The second sleeve pipe 23 and the second collimation lens 25 lay respectively at the relative both sides of the second angle of wedge sheet 24, and the second collimation lens 25 is located at the side of the second angle of wedge sheet 24 near single optical fiber calibrators 50; Pumping optical fiber 21 1 ends enter in the second angle of wedge sheet 24 through the second sleeve pipe 23 plug-in mountings; Double clad polarization maintaining optical fibre 22 1 ends enter in the second angle of wedge sheet 24 through the second sleeve pipe 23 plug-in mountings; Pumping optical fiber 21 all is fixedly linked by solidifying glue and the second sleeve pipe 23 with double clad polarization maintaining optical fibre 22.
Pumping optical fiber 21 is for launching pump light.Double clad polarization maintaining optical fibre 22 receives the flashlight of the first polarization maintaining optical fibre 52 emission for correspondence or to the first polarization maintaining optical fibre 52 light that transmits.When double clad polarization maintaining optical fibre 22 transmits the light time, the second collimation lens 25 collimates for the signal that double clad polarization maintaining optical fibre 22 is emitted to the first polarization maintaining optical fibre 52.Filter plate 30 is for pump light being reflexed to the covering of double clad polarization maintaining optical fibre 22, simultaneously the flashlight of transmission the first polarization maintaining optical fibre 52 or 22 emissions of double clad polarization maintaining optical fibre.The second collimation lens 25 also collimates for the pump light by pumping optical fiber 21 emissions.Flashlight transmits in the fibre core of double clad polarization maintaining optical fibre 22 and the first polarization maintaining optical fibre 52, and pump light transmits in the covering of double clad polarization maintaining optical fibre 22.
The first angle of wedge sheet 40 is for the angle of conditioning signal light, so that the signal luminous energy that the first polarization maintaining optical fibre 52 sends is accurately injected in the fibre core of double clad polarization maintaining optical fibre 22, or the signal luminous energy that double clad polarization maintaining optical fibre 22 is launched is injected in the fibre core of the first polarization maintaining optical fibre 52 exactly.
