Fiber splicing feem ntau muab faib ua plaub theem: stripping, txiav, melting, thiab tiv thaiv:
Stripping:hais txog kev stripping ntawm optical fiber core nyob rau hauv lub optical cable, uas muaj xws li cov txheej txheej yas, nruab nrab hlau hlau, txheej yas puab thiab cov xim pleev xim txheej rau ntawm qhov chaw ntawm fiber ntau optical.
Txiav:Nws yog hais txog kev txiav lub ntsej muag kawg ntawm cov khoom siv kho qhov muag uas tau raug stripped thiab npaj tau fused nrog "cutter".
Fusion:yog hais txog fusion ntawm ob fibers optical ua ke hauv "fusion splicer".
Kev tiv thaiv:Nws yog hais txog kev tiv thaiv spliced optical fiber connector nrog ib tug "heat shrinkable raj":
1. Kev npaj lub ntsej muag kawg
Kev npaj ntawm lub ntsej muag fiber ntau suav nrog stripping, tu thiab txiav.Lub ntsej muag uas tsim nyog fiber ntau yog qhov tsim nyog rau fusion splicing, thiab qhov zoo ntawm lub ntsej muag kawg ncaj qha cuam tshuam rau qhov zoo ntawm fusion splicing.
(1) Stripping ntawm optical fiber txheej
Paub nrog lub tiaj, ruaj khov, ceev peb lub cim fiber ntau stripping txoj kev."Ping" txhais tau tias khaws cov fiber ntau.Pinch lub optical fiber nrog tus ntiv tes xoo thiab ntiv tes ntiv tes ntawm sab laug tes kom nws kab rov tav.Qhov ntev ntawm qhov nthuav dav yog 5 cm.Qhov seem fiber ntau yog ib txwm khoov ntawm tus ntiv tes ntiv tes thiab tus ntiv tes me me kom muaj zog thiab tiv thaiv kom tsis txhob ntog.
(2) Ntxuav cov fibers liab qab
Saib xyuas seb cov txheej txheej ntawm cov stripped ib feem ntawm cov khoom siv kho qhov muag puas tau stripped tag.Yog tias muaj qhov seem, nws yuav tsum tau muab tshem tawm dua.Yog tias muaj cov txheej txheej me me uas tsis yooj yim rau tev tawm, siv lub pob paj rwb dipped rau hauv ib qho dej cawv uas tsim nyog, thiab so nws maj mam thaum dipping.Ib daim paj rwb yuav tsum tau hloov nyob rau lub sijhawm tom qab siv 2-3 zaug, thiab cov khoom sib txawv thiab cov khaubncaws sab nraud povtseg yuav tsum tau siv txhua zaus.
(3) Txiav ntawm liab qab fiber
Kev xaiv ntawm Cutter Muaj ob hom cutters, phau ntawv thiab hluav taws xob.Lub qub yog yooj yim rau kev khiav lag luam thiab txhim khu kev qha hauv kev ua haujlwm.Nrog rau kev txhim kho ntawm tus neeg teb xov tooj qib, qhov kev ua tau zoo thiab kev ua tau zoo tuaj yeem txhim kho tau zoo, thiab cov liab qab fiber ntau yuav tsum tau luv dua, tab sis lub cutter muaj cov kev xav tau siab dua ntawm qhov sib txawv ntawm qhov kub thiab txias.Lub tom kawg muaj kev txiav zoo dua qub thiab tsim nyog rau kev ua haujlwm hauv qhov chaw txias, tab sis kev ua haujlwm nyuaj dua, kev ua haujlwm ceev yog qhov tas li, thiab cov liab qab fiber ntau yuav tsum tau ntev dua.Nws raug nquahu kom cov neeg ua haujlwm txawj siv phau ntawv txiav rau kev ceev kho qhov muag cable splicing lossis kev cawm thaum muaj xwm txheej ceev ntawm chav tsev kub;ntawm qhov tsis sib xws, cov neeg pib tshiab lossis thaum ua haujlwm nyob rau hauv qhov chaw txias dua, siv cov tshuab hluav taws xob ncaj qha.
Ua ntej tshaj plaws, ntxuav lub cutter thiab kho qhov chaw ntawm lub cutter.Lub cutter yuav tsum tau muab tso rau stably.Thaum txiav, lub zog yuav tsum yog ntuj thiab ruaj khov.Tsis txhob hnyav lossis ntxhov siab kom tsis txhob tawg fibers, bevels, burrs, tawg thiab lwm yam phem kawg ntsej muag.Tsis tas li ntawd, rationally faib thiab siv ib tus ntiv tes txoj cai kom lawv sib haum thiab sib koom tes nrog rau qhov tshwj xeeb ntawm lub tshuab txiav, txhawm rau txhim kho kev txiav ceev thiab zoo.
Ceev faj ntawm kev kis kab mob ntawm qhov kawg.Lub tes tsho kub shrinkable yuav tsum tau muab tso ua ntej stripping, thiab nws yog nruj me ntsis txwv tsis pub nkag mus tom qab qhov kawg nto yog npaj.Lub sij hawm ntawm kev ntxuav, txiav thiab vuam ntawm liab qab fibers yuav tsum tau zoo sib xws, thiab lub ncua sij hawm yuav tsum tsis txhob ntev heev, tshwj xeeb tshaj yog npaj kawg lub ntsej muag yuav tsum tsis txhob muab tso rau hauv cov huab cua.Ua tib zoo saib xyuas thaum txav mus los tiv thaiv kev sib tsoo ntawm lwm yam khoom.Thaum lub sij hawm splicing, "V" zawj, siab phaj thiab hniav ntawm lub cutter yuav tsum tau muab ntxuav raws li ib puag ncig kom tsis txhob muaj kab mob ntawm qhov kawg nto.
2. Fiber splicing
(1) Kev xaiv lub tshuab vuam
Kev xaiv ntawm fusion splicer yuav tsum tau nruab nrog fusion splicing cov cuab yeej uas tsim nyog lub roj teeb muaj peev xwm thiab precision raws li qhov yuav tsum tau muaj ntawm qhov project optical cable.
(2) Parameter teeb tsa ntawm vuam tshuab
Splicing txheej txheem Raws li cov khoom thiab hom fiber ntau optical ua ntej splicing, teem lub ntsiab tsis xws li pre-melting lub ntsiab melting tam sim no thiab lub sij hawm, thiab tus nqi ntawm fiber ntau pub.
Thaum lub sij hawm vuam txheej txheem, "V" zawj, electrode, lub hom phiaj lens, vuam chamber, thiab lwm yam ntawm lub vuam tshuab yuav tsum tau ntxuav nyob rau hauv lub sij hawm, thiab tej yam phem tshwm sim xws li npuas, nyias nyias, tuab heev, virtual melting, sib cais, thiab lwm yam yuav tsum tau saib xyuas thaum lub sijhawm vuam txhua lub sijhawm, thiab kev saib xyuas yuav tsum tau them rau kev taug qab thiab saib xyuas cov txiaj ntsig ntawm OTDR.Tshawb xyuas qhov ua rau ntawm qhov tshwm sim tsis zoo saum toj no hauv lub sijhawm thiab siv cov kev txhim kho zoo sib xws.
3, disc fiber ntau
Txoj kev tshawb fawb fiber ntau tuaj yeem ua rau qhov kho qhov muag fiber ntau tsim nyog, qhov poob ntxiv yog me me, tuaj yeem tiv taus qhov kev sim ntawm lub sijhawm thiab ib puag ncig hnyav, thiab tuaj yeem zam qhov tshwm sim ntawm fiber ntau tawg los ntawm extrusion.
(1) Disk fiber ntau txoj cai
Lub fiber yog coiled nyob rau hauv units raws lub xoob raj los yog branching kev taw qhia ntawm optical cable.Qhov qub yog siv tau rau txhua qhov haujlwm splicing;tom kawg tsuas yog siv tau rau qhov kawg ntawm lub ntsiab kho qhov muag cable, thiab muaj ib qho kev tawm tswv yim thiab ntau qhov tawm.Feem ntau ntawm cov ceg yog me me logarithmic optical cables.Txoj cai yog reel cov fibers ib zaug tom qab splicing thiab tshav kub-shrinking ib los yog ob peb fibers nyob rau hauv xoob hlab, los yog fibers nyob rau hauv ib tug split taw qhia cable.Qhov zoo: Nws zam qhov tsis meej pem ntawm optical fibers ntawm xoob hlab ntawm optical fibers los yog ntawm txawv ceg kho qhov muag cables, ua rau nws tsim nyog nyob rau hauv layout, yooj yim rau reel thiab dismantle, thiab yooj yim rau kev tswj yav tom ntej.
(2) Txoj kev ntawm disk fiber ntau
Ua ntej nruab nrab thiab tom qab ntawd ob sab, uas yog, ua ntej tso lub tes tsho kub-shrinkable nyob rau hauv kho zawj ib los ntawm ib qho, thiab tom qab ntawd ua cov fibers ntxiv rau ob sab.Qhov zoo: Nws yog qhov zoo los tiv thaiv cov pob qij txha fiber ntau thiab zam kev puas tsuaj los ntawm fiber ntau coil.Txoj kev no feem ntau yog siv thaum qhov chaw tshwj tseg rau cov khoom siv kho qhov muag me me thiab cov khoom siv kho qhov muag tsis yooj yim rau coil thiab kho.
