Background technology
In recent years along with fiber-to-the-home enforcement, home light networks is in great demand, EPON, the output of GPON optical module and optical device increases sharply, EPON, the required BOSA device of GPON emissive power is large, the otherness of the loss of fiber stub assembly and four direction loss is required strict, fiber stub assembly manufacturer to the conventional test methodologies of the directional difference of product is at present: on a support, modulate directivity and carry out testing after manual welding again, they are not with direction positioning function, directly welding there are differences, directivity utmost point out of true, human factor impact is large, if test performance is poor after welding, the assembly of welding must be taken off to welding again tests again.And optical device manufacturer is coupled fiber stub assembly and laser instrument TO after welding, could travel direction difference test, inconvenient operation, causes waste of raw materials, and same accuracy is not high.
Summary of the invention
The problems such as the purpose of this utility model will solve existing fiber ferrule assembly directivity detection method inconvenient operation exactly, and waste of raw materials is large, and test result is inaccurate, provide a kind of directivity precise detection device of fiber stub assembly.
Concrete scheme of the present utility model is: a kind of directivity precise detection device of fiber stub assembly, there is base, it is characterized in that: on base, left and right is provided with three-dimensional adjustable shelf and ferrule assembly holder, top at three-dimensional adjustable shelf is provided with electrode tip holder, laser instrument is housed on electrode tip holder, the relative ferrule assembly holder of head of laser instrument is arranged, on the supporting plate of ferrule assembly holder, over against laser instrument, have pilot hole, on supporting plate, be positioned at pilot hole rear side a direction set collar is also housed, the inner headed face of this direction set collar is provided with two boss that are arranged symmetrically with, this boss be with ceramic contact pin caudal peduncle on draw-in groove agree with design.
The L-shaped structure of electrode tip holder described in the utility model, its vertical panel is faced ferrule assembly holder and is arranged, and on vertical panel, has through hole installation laser instrument.
Using method of the present utility model is: (1) tested ferrule assembly is inserted the pilot hole of ferrule assembly holder from front side, one end of optical patchcord is inserted on a ceramic contact pin caudal peduncle, pilot hole rear side plug-in mounting ceramic contact pin caudal peduncle from holder, and agree with location by the draw-in groove on the boss on set collar and ceramic contact pin caudal peduncle, optical patchcord and ferrule assembly precision are docked, and the other end of optical patchcord connects light power meter by connector; (2) laser is sent in laser instrument energising; (3) regulate three of three-dimensional adjustable shelf axially, coupled optical power is to 1000uw; (4) on four direction, rotate plug ceramic contact pin caudal peduncle and optical patchcord, distinguish recording powers of laser beam, and calculate the difference of its directivity.
Feature of the present utility model is: (1) adopt the tested fiber stub assembly that couples light to that three-dimensional adjustable shelf sends laser instrument, changed situation about needing on market tested optical fiber ferrule assembly and laser instrument welding, saved the test duration, and saved starting material;
(2) adopt optical patchcord set collar, by optical patchcord and ceramic insertion core caudal peduncle draw-in groove fixed fiber wire jumper direction, can carry out each 90 degree rotations, limited after optical patchcord inserts fiber stub assembly simultaneously and had slight rotation, destroyed fiber end face;
(3) the utility model is easy to operate, quick;
(4) directivity is had good positioning, and has improved measuring accuracy, and precision can reach ± 1 ° (former artificial malobservation is more than ± 5 °).
