As shown in fig. 6, a coordinate position is found in the central area of the intersection of orthogonal X1 and Y2 scanning narrow slits,
It is established as central point.Herein (X:1680, Y:1680) coordinate points are set to central point.Set after central point, in light beam spot
It can be appreciated that light beam spot in center position in monitoring window 12.Light beam spot is exactly the single beam that arrives of probe detection of hot spot machine.It
Afterwards, a single mode to be adjusted often is debuggedLong reach single mode single fiber is accurate in Ultra optical fiber 1310nm 200WD
Straight device, is required for from single mode to be adjustedLong reach single mode single fiber in Ultra optical fiber 1310nm 200WD
Coordinate position of the light beam spot regulation that collimater is launched to central point.
As shown in figure 8, with long reach single mode single optical fiber calibrator in 0 degree of angle to five times regualting frame and hot spot machine
Carry out on perpendicularity regulation, Mobile Slide at hot spot machine to 100mm distances, the two-dimentional pitching angle knob on regulation five times regualting frame
22 light beam spots for being allowed to long reach single mode single optical fiber calibrator in 0 degree of angle move to central point；Hot spot machine on Mobile Slide again
To 5mm distances, the X and Y-axis adjusting knob for adjusting X-Y-Z axle single shaft displacement adjusting brackets are allowed to long reach list in 0 degree of angle
The light beam spot of mould single optical fiber calibrator moves to central point.Back and forth several times, it is allowed to farm labourer in 0 degree of angle of 100mm distances and 5mm distances
Make all to fall on central point apart from the light beam spot of single mode single optical fiber calibrator.
As shown in Figure 9 and Figure 10, described single mode to be adjustedIt is long in Ultra optical fiber 1310nm 200WD
Operating distance single mode single optical fiber calibrator frame is on the one-dimensional adjusting bracket on five times regualting frame, away from the spy that hot spot machine is placed at 30mm
The spot size and coordinate bit of single beam in head, the spot size 13.5% of monitoring light beam and the data display window 13 of position
Put.The X and Y-axis adjusting knob of X-Y-Z axle single shaft displacement adjusting brackets are adjusted, single mode to be adjustedUltra optical fiber
Coordinate position of the light beam spot regulation that long reach single mode single optical fiber calibrator is launched in 1310nm200WD to central point.
Described single mode to be adjusted is adjusted by one-dimensional adjusting bracketLong reach in Ultra optical fiber 1310nm 200WD
The single mode of single mode single optical fiber calibratorGap between Ultra single fibers tail optical fiber and R2.978 planoconvex spotlights, modulation
In the range of 695~710um of spot size control interval at spot size to 30mm operating distances.Take X1 and Y2 to scan narrow slit to obtain
Minimum value in two spot sizes of single beam is taken as the spot size of final reference.Ordinary circumstance, Y2 scanning narrow slits are obtained
Spot size be less than X1 scanning narrow slit obtain spot size.
As is illustrated by figs. 11 and 12, the probe of hot spot machine is pulled in this at long reach 200mm by slide unit, checked
Spot size herein.If meeting 720~800um of spot size control range at long reach in 200mm.Without again
Regulation.But according to practical operation experience, due to the middle whole work of long reach single mode single optical fiber calibrator of middle long reach
Work distance is longer, and beam divergence angle is smaller, the single mode adjusted at 30mmUltra single fibers tail optical fiber and R2.978
Gap between planoconvex spotlight can not sufficiently accurately the single beam launched be shaped into 100mm or so places it is with a tight waist and on
Place's axisymmetric Gaussian beam in position with a tight waist.It is general to occur two kinds of situations, hot spot of the one in this at long reach 200mm
Size is big to more than 850um；Secondly the spot size in this at long reach 200mm can as low as below 650um.So encountering
This two kinds of situations are required for adjusting one-dimensional adjusting bracket again, and spot size is modulated in 200mm the hot spot at long reach
720~800um of big minor control field.This control range is larger, is adjusted according to the smaller the better principle of regulated quantity.For in
The middle long reach single mode single optical fiber calibrator of long reach, can in right amount shorten actual long reach in this, all
Extraordinary coupling insertion loss can be obtained.
In a single modeLong reach single mode single optical fiber calibrator in Ultra optical fiber 1310nm 200WD
Hot spot machine debugging step in need by location of the core, perpendicularity regulation, operating distance 30mm spot sizes regulation, middle length
Operating distance 200mm spot sizes adjust four steps and completed.First three sample single modesUltra optical fiber 1310nm
After long reach single mode single optical fiber calibrator completes in 200WD, transmission beam method arbitrarily need in pairs it be mutually measured on micropositioning stage
Insertion loss at 1310nm wavelength, Insertion Loss will test former two single modes within 0.3dB using transmission beam method
The distance between long reach single mode single optical fiber calibrator is long reach in this in Ultra optical fiber 1310nm 200WD
200mm。
Employ the hot spot of the middle long reach single mode single optical fiber calibrator of middle long reach in the utility model
Machine debugging system, reduces the debugging difficulty of light path, improves adjustment accuracy, makes middle long reach single mode single optical fiber calibrator
Insertion loss is smaller, paired interaction is higher, homogeneity of product and first-time qualification rate are higher, reduce debug time, improve
The operating efficiency of employee, and it is equally applicable to the middle long reach of the middle long reach of special wave band 850nm, 1060nm
Single mode single optical fiber calibrator, is with a wide range of applications.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still can be with
Various modification can be adapted and conversion is without departing from spirit and scope of the present utility model.Therefore, specification and drawings are considered as
It is illustrative and not restrictive.
