I. Fusion Loss Test nrog cov cuab yeej txheem
Lub hom phiaj tseem ceeb tom qab calibration yog txo thiab stabilize fusion poob, uas yuav tsum tau ntsuas tus nqi poob tiag tiag siv cov cuab yeej tshwj xeeb.
1. OTDR (Optical Time Domain Reflectometer) Bidirectional Test Method
Txuas ob qhov kawg ntawm cov fiber ntau hauv kev sim mus rau OTDR rau kev sim bidirectional.
Siv qhov nruab nrab ntawm qhov poob qhov tseem ceeb ntsuas nyob rau hauv ob qho tib si cov lus qhia raws li qhov kawg tshwm sim los tshem tawm kev ntsuas kev tsis ncaj ncees los ntawm Rayleigh tawg.
Kev lees paub tus qauv: Ib qho -hom fiber ntau fusion splice poob Tsawg dua lossis sib npaug rau 0.05dB, zoo tagnrho tus nqi Tsawg dua lossis sib npaug rau 0.02dB.
2. Lub teeb Source + Optical Power Meter Insertion Method
Siv lub teeb pom kev ruaj khov thiab lub ntsuas hluav taws xob kho qhov muag los ntsuas qhov hloov pauv ntawm lub zog kho qhov muag ua ntej thiab tom qab fusion splicing.
Thaum lub sijhawm ua haujlwm, tus nqi siv tuaj yeem raug xoom ua ntej, thiab tom qab ntawd qhov poob tom qab fusion splicing tuaj yeem ntsuas los txhim kho qhov tseeb.
Qhov zoo: Tus nqi qis, kev ua haujlwm yooj yim, tsim nyog rau kev ceev ceev ntawm - qhov chaw pov thawj.
II. Fiber Axial thiab Angular Deviation Detection
Calibration ncaj qha cuam tshuam rau qhov tseeb ntawm cov tub ntxhais fiber ntau thiab yuav tsum tau muaj kev pov thawj uas siv lub siab -kev ntsuas qhov tseeb.
1. Microscopic Imaging System Tshuaj xyuas
Saib xyuas cov tub ntxhais kawm ntawv fiber ntau ua ntej thiab tom qab fusion splicing siv X / Y-axis microscope ua rau hauv fusion splicer.
Tshawb xyuas cladding misalignment, fiber core offset, los yog kawg -lub ntsej muag qaij.
Kev tso cai yuam kev: Axial sib txawv <0.5μm, angular sib txawv <0.5 degree.
2. Interferometry Technology (Suitable rau siab -qhov tseeb scenarios)
Siv qhov ntsuas qhov muag cuam tshuam los ntsuas qhov kawg - lub ntsej muag lub ntsej muag thiab qhov sib xws; feem ntau yog siv rau kev kuaj-qib pov thawj.
III. V-groove thiab Electrode Status Recheck
Tom qab calibration, paub meej tias cov khoom tseem ceeb nyob rau hauv kev ua haujlwm zoo.
1. V-Zoo huv xyuas
Tom qab so nrog dej cawv so, paub meej tias nyob rau hauv lub tshuab ntsuas pom tias tsis muaj plua plav lossis fiber ntau seem.
Kev tu tsis zoo tuaj yeem ua rau fiber ntau qhov chaw tsis zoo, cuam tshuam rau kev sib raug zoo.
2. Electrode Discharge Correction Verification
Tom qab ua tiav cov txheej txheem "kho tawm", saib seb lub arc puas yog nruab nrab thiab ruaj khov.
Yog hais tias lub arc yog offset los yog flickering, lub electrode yuav tsum tau muab ntxuav dua los yog hloov.
IV. Thaum tshav kub kub Shrink Protection Performance Test Mechanical tiv thaiv ntawm lub splice yog qhov tseem ceeb sib npaug; Lub qhov cub cua sov yuav tsum raug txheeb xyuas kom ua haujlwm kom raug.
1. Thaum tshav kub kub Shrink Tube cua sov Uniformity
Siv cov txheej txheem cua sov shrink tubing rau cua sov thiab saib seb lub shrinkage zoo li cas thiab tsis muaj cua npuas.
Tom qab cua sov, lub tubing yuav tsum tau pob tshab, nruj nreem txuas rau lub optical fiber, thiab steel pas nrig yuav tsum tau nruab nrab thiab tsau.
2. Lub sij hawm cua sov thiab kub sib xws
Qhov ntau thiab tsawg tubing (piv txwv li, 20mm, 60mm) yuav tsum tau sib txawv lub sij hawm cua sov; cov no yuav tsum tau teeb tsa raws li cov lus qhia ntawm cov cuab yeej siv.
V. Repeatability thiab Stability Verification Verify lub sij hawm ntev - stability tom qab calibration los ntawm rov ua hauj lwm.
1. Tus nqi nruab nrab ntawm 5 lossis ntau qhov txuas txuas ntxiv
Siv cov khoom siv tib yam ntawm cov qauv kho qhov muag kom rov ua dua, sau cov kwv yees poob thiab ntsuas OTDR tus nqi txhua zaus.
Txheeb xyuas cov ntaub ntawv dispersion, tshem tawm cov outliers, thiab xyuas kom meej tias cov txiaj ntsig tau rov ua dua.
2. Environmental Adaptability Test (Yeem)
Rov kuaj dua nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias hloov pauv kom paub tseeb qhov ua tau zoo ntawm qhov kub thiab txias ua haujlwm.
