Fiber Optic Cable (FOC) yog ib feem tseem ceeb ntawm kev sib txuas lus niaj hnub no, thiab nws nyob hauv txoj haujlwm tseem ceeb hauv kev xa cov ntaub ntawv nrog nws cov yam ntxwv ntawm kev kub ceev, bandwidth siab thiab muaj peev xwm tiv thaiv kev cuam tshuam. Tsab xov xwm no yuav qhia txog cov qauv ntawm fiber optic cable kom meej kom cov nyeem ntawv nkag siab tob dua txog nws.
1. Cov khoom xyaw yooj yim ntawm cov xov hlau fiber-optic
Fiber optic cable feem ntau yog tsim los ntawm peb ntu: fiber optic core, cladding thiab sheath.
Lub hauv paus fiber opticQhov no yog lub plawv ntawm cov xov hlau fiber optic thiab yog lub luag haujlwm rau kev xa cov teeb liab pom kev. Cov hlab fiber optic feem ntau yog ua los ntawm cov iav ntshiab heev lossis yas, nrog rau txoj kab uas hla ntawm ob peb microns xwb. Kev tsim ntawm lub plawv ua kom ntseeg tau tias cov teeb liab pom kev mus los ntawm nws tau zoo thiab nrog kev poob qis heev.
Kev tiv thaiv: Ib puag ncig lub hauv paus ntawm lub fiber yog lub cladding, uas nws cov refractive index qis dua me ntsis ntawm lub hauv paus, thiab uas yog tsim los tso cai rau lub teeb liab optical kom xa mus rau hauv lub hauv paus hauv txoj kev reflective tag nrho, yog li txo cov teeb liab poob. Lub cladding kuj yog ua los ntawm iav lossis yas thiab lub cev tiv thaiv lub hauv paus.
Lub tsho lojLub tsho sab nraud tshaj plaws yog ua los ntawm cov khoom siv tawv xws li polyethylene (PE) lossis polyvinyl chloride (PVC), uas nws lub luag haujlwm tseem ceeb yog tiv thaiv lub fiber optic core thiab cladding los ntawm kev puas tsuaj ib puag ncig xws li kev puas tsuaj, dej noo thiab tshuaj lom neeg xeb.
2. Hom fiber-optic cables
Raws li kev npaj thiab kev tiv thaiv ntawm cov fiber ntau optical, cov cables fiber optic tuaj yeem muab faib ua cov hom hauv qab no:
Cov kab hluav taws xob fiber optic uas muaj laminated: cov qauv no zoo ib yam li cov cables ib txwm muaj, uas ntau lub fibers optical raug khi ncig lub hauv paus reinforcing, tsim kom muaj qhov zoo li cov cables classical. Cov laminated stranded fiber optic cables muaj lub zog tensile siab thiab cov khoom zoo bending, thiab muaj lub cheeb me me, ua rau lawv yooj yim rau kev thiab tswj.
Cov xov hlau pob txha: cov cable no siv cov pob txha yas ua cov qauv txhawb nqa ntawm cov fiber ntau optical, cov fiber ntau optical yog tsau rau hauv cov grooves ntawm cov pob txha, uas muaj cov khoom tiv thaiv zoo thiab kev ruaj khov ntawm cov qauv.
Lub cev kab hlau txuas nruab nrab: cov fiber optic muab tso rau hauv nruab nrab ntawm lub raj fiber optic, puag ncig los ntawm lub hauv paus reinforcing thiab lub tsho tiv thaiv, cov qauv no yog qhov zoo rau kev tiv thaiv cov fiber optic los ntawm kev cuam tshuam sab nraud.
Txoj hlua khi: cov fibers optical tau teeb tsa ua daim ntawv ntawm cov ribbons nrog qhov sib nrug ntawm txhua cov fiber ribbon, qhov kev tsim no pab txhim kho lub zog tensile thiab lateral compression tsis kam ntawm lub cable.
3. Cov khoom ntxiv ntawm cov xov hlau fiber-optic
Ntxiv rau cov fiber ntau optical, cladding thiab sheath, cov fiber optic cables yuav muaj cov khoom ntxiv hauv qab no:
Lub hauv paus txhawb zogNyob rau hauv nruab nrab ntawm lub fiber optic cable, nws muab ntxiv lub zog mechanical los tiv taus tensile lub zog thiab kev ntxhov siab.
Txheej tsis: Nyob nruab nrab ntawm cov fiber thiab lub hnab, nws tiv thaiv cov fiber ntxiv los ntawm kev cuam tshuam thiab kev puas tsuaj.
Txheej txheem tiv thaivQee cov xov hlau fiber optic kuj muaj ib txheej armouring ntxiv, xws li steel daim kab xev armouring, los muab kev tiv thaiv ntxiv rau qhov chaw nyuaj lossis qhov twg xav tau kev tiv thaiv tshuab ntxiv.
4. Cov txheej txheem tsim khoom rau cov xov hlau fiber-optic
Kev tsim khoom ntawmcov xov hlau fiber opticmuaj cov txheej txheem raug siab, suav nrog cov kauj ruam xws li kos duab ntawm cov fiber optics, txheej txheej ntawm cladding, stranding, tsim cov cable thiab sheath extrusion. Txhua kauj ruam yuav tsum tau tswj hwm nruj me ntsis kom ntseeg tau tias qhov ua tau zoo thiab zoo ntawm cov fiber optic cable.
Hauv kev xaus lus, kev tsim qauv ntawm cov xov hluav taws xob fiber ntau suav nrog ob qho tib si kev xa cov teeb liab pom kev zoo thiab kev tiv thaiv lub cev thiab kev hloov pauv ib puag ncig. Nrog rau kev nce qib tas mus li ntawm thev naus laus zis, cov qauv thiab cov ntaub ntawv ntawm cov xov hluav taws xob fiber ntau tau raug kho kom zoo dua kom tau raws li qhov kev thov loj hlob rau kev sib txuas lus.
