Fiber Splicing yog dab tsi?

Fusion splicer yog qhov kev ua ntawm kev koom ua ke ob lub fibers optical kawg-rau-kawg. Lub hom phiaj yog los fuse ob lub fibers ua ke hauv txoj kev uas lub teeb hla dhau cov fibers tsis tawg lossis cuam tshuam rov qab los ntawm splice, thiab yog li ntawd qhov splice thiab thaj chaw nyob ib puag ncig nws yuav luag muaj zog zoo li cov fiber tsis muaj qhov puas tsuaj. Thaum ua kom raug, splicing tsim ib lub cable nrog kev ruaj khov zoo dua thiab tsawg kawg poob. Ua tsaug rau fiber fusion, thaum lub fiber tawg, cov ntaub ntawv loj heev tseem tuaj yeem khiav sai hauv kev sib txuas lus hauv network.

Kev Sib Txuas Lus Mechanical: Ib qho kev sib koom ua ke sib dhos ob lossis ntau dua cov xov fiber tawg thiab tuav cov fiber ua ke los ntawm ib qho kev sib dhos. Kev sib txuas ua ke siv sijhawm thiab kev siv zog tsawg dua, tsis siv hluav taws xob thiab muaj ob peb yam cuab yeej. Txawm li cas los xij, kev sib txuas ua ke feem ntau suav tias yog ib ntus thiab tuaj yeem ua rau muaj kev poob ntawm kev ntxig txog li 0.3 dB.

Kev sib txuas fusion: Kev sib txuas fiber ntau yog txoj kev sib txuas fiber ntau tshaj plaws thiab kuj yog txoj kev tseem ceeb uas tau tham hauv tsab xov xwm no. Hauv cov txheej txheem sib txuas fusion, lub tshuab sib txuas tshwj xeeb siv los sib dhos ob lub fiber kawg ces cov iav kawg raug sib txuas ua ke siv hluav taws xob arc lossis qee yam cua sov. Qhov zoo ntawm txoj kev vuam no yog tias nws tsim cov pob tshab, tsis muaj kev cuam tshuam thiab txuas ntxiv mus ntawm cov fiber ntau, thiab ua tiav qhov poob qis heev, feem ntau tsuas yog 0.1db poob.

Ob txoj kev siv fiber splicing feem ntau yog fusion thiab mechanical. Ob qho tib si fusion thiab mechanical splicing ua tiav tib lub hom phiaj, uas txuas ob lub fiber optical ua ke kom cov teeb liab tuaj yeem mus tau zoo los ntawm lawv. Feem ntau hais lus, nws raug pom zoo kom siv fusion splicing. Txoj kev no muaj kev poob qis thiab cov nqi kho tom qab qis. Tom ntej no, cov kauj ruam ua haujlwm tshwj xeeb ntawm txoj kev fusion splicing no yuav raug qhia.

Yuav ua li cas txuas cov fiber optic cables?

Kauj Ruam 1:Kev Npaj Fiber. Ua ntej peb yuav tsum siv cov cuab yeej stripping cable los tshem tawm cov txheej tiv thaiv ntawm cov fiber optical, xws li cladding, jacket, thiab sheath. Cov fiber liab qab yuav tsum tau ntxuav kom zoo siv paj rwb cawv kom ntseeg tau tias nws huv si.

Kauj Ruam 2: Txiav cov fiber. Cov cuab yeej txiav fiber yog siv rau kev txiav. Qhov no yog ib qho ntawm cov kauj ruam tseem ceeb tshaj plaws. Kev txiav fiber tsis zoo lossis kev txiav tsis zoo tuaj yeem ua rau qhov sib koom ua ke ntawm qhov vuam tsis zoo. Yog vim li cas peb thiaj yuav tsum ua cov kauj ruam no kom zoo. Qhov chaw txiav zoo yog tiaj tus, uas yog qhov zoo rau kev ua haujlwm splicing tom qab.

Kauj Ruam 3: Muab cov fiber ntau optical uas tau npaj tseg rau hauv ob sab ntawm lub tshuab fiber ntau optic splicing thiab khi lawv kom ruaj khov. Lub fusion splicer ua ntej siv lub tshuab microscope thiab lub cev muaj zog 3D los tso lub fiber. Kev teeb tsa lub fiber txhais tau tias phim nws cov kawg kom zoo meej kom lub teeb tuaj yeem mus los ntawm ib lub fiber mus rau lwm qhov nrog qhov poob tsawg kawg nkaus, kev cuam tshuam, lossis kev cuam tshuam. Tom qab kev teeb tsa tiav lawm, lub arc hluav taws xob tau tsim ntawm cov electrodes, l yaj lub fiber ntau optical. Cov pob qij txha fused tom qab ntawd tau sim rau lub zog kho tshuab thiab kev sib koom ua ke. Ua li no, qhov splicing tiav lawm, l tab sis qhov splicing yog rhiab heev thiab xav tau kev tiv thaiv.

Kauj Ruam 4: Kev Tiv Thaiv Fiber: Ib qho kev sib koom ua ke feem ntau muaj lub zog tensile ntawm 0.5 thiab 1.5 phaus thiab yuav tsis tawg thaum lub sijhawm tuav ib txwm. Tab sis txhawm rau tiv thaiv cov fiber los ntawm kev khoov thiab rub zog, peb yuav tsum siv cov tes tsho tiv thaiv fiber optic, silicone lossis cov neeg kho tshuab crimp tiv thaiv los tiv thaiv lub connector los ntawm cov yam sab nraud thiab kev tawg.
