Fiber Optic Cable (FOC) yog ib qho tseem ceeb ntawm cov 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, siab bandwidth thiab muaj zog tiv thaiv kev cuam tshuam. Kab lus no yuav qhia txog cov qauv ntawm fiber ntau optic cable kom ntxaws kom cov neeg nyeem tuaj yeem nkag siab tob txog nws.
1. Basic muaj pes tsawg leeg ntawm fiber-optic cable
Fiber optic cable yog tsim los ntawm peb qhov chaw: fiber ntau optic core, cladding thiab sheath.
Fiber optic tub ntxhais: Qhov no yog lub hauv paus ntawm fiber ntau optic cable thiab yog lub luag haujlwm rau kev xa cov teeb liab kho qhov muag. Fiber optic cores feem ntau yog ua los ntawm cov iav ntshiab los yog yas, nrog ib txoj kab uas hla ntawm ob peb microns. Kev tsim ntawm cov tub ntxhais ua kom ntseeg tau tias cov teeb liab kho qhov muag mus los ntawm nws tau zoo thiab nrog kev poob qis heev.
Cladding: Nyob ib puag ncig ntawm cov tub ntxhais ntawm cov fiber ntau yog cov cladding, uas nws qhov refractive index yog me ntsis qis dua li ntawm cov tub ntxhais, thiab uas yog tsim los tso cai rau cov teeb liab optical kis tau rau hauv cov tub ntxhais nyob rau hauv ib tug tag nrho reflective yam, yog li txo cov teeb liab poob. Lub cladding kuj yog ua los ntawm iav los yog yas thiab lub cev tiv thaiv cov tub ntxhais.
Jacket: Lub tsho sab nraud yog ua los ntawm cov khoom siv tawv xws li polyethylene (PE) lossis polyvinyl chloride (PVC), uas nws lub luag haujlwm tseem ceeb yog los tiv thaiv cov tub ntxhais fiber ntau thiab cov cladding los ntawm ib puag ncig kev puas tsuaj xws li kev puas tsuaj, ya raws thiab tshuaj lom neeg corrosion.
2. Hom fiber-optic cables
Raws li kev npaj thiab kev tiv thaiv ntawm optical fibers, fiber ntau optic cables tau muab faib ua hom hauv qab no:
Laminated stranded fiber ntau optic cable: Cov qauv no zoo ib yam li cov kab hluav taws xob ib txwm muaj, uas muaj ntau yam khoom siv kho qhov muag tau tso tseg nyob ib ncig ntawm lub hauv paus tseem ceeb, tsim kom muaj qhov zoo ib yam li cov cables classical. Laminated stranded fiber optic cables muaj zog tensile siab thiab zoo dabtsi yog khoov zog, thiab muaj ib tug me me txoj kab uas hla, ua rau lawv yooj yim rau txoj kev thiab tswj.
Skeleton kab: Cov kab no siv cov pob txha yas ua cov qauv kev txhawb nqa ntawm cov khoom siv kho qhov muag, cov khoom siv kho qhov muag tau tsau rau hauv cov grooves ntawm cov pob txha, uas muaj kev tiv thaiv zoo thiab cov qauv kev ruaj ntseg.
Center pob tube cable: optical fiber yog muab tso rau hauv nruab nrab ntawm lub optical cable tube, ib puag ncig los ntawm ib tug reinforcing core thiab lub tsho tiv thaiv, cov qauv no yog haum rau kev tiv thaiv ntawm optical fibers los ntawm sab nraud influences.
Ribbon kab: cov fibers kho qhov muag tau teem rau hauv daim ntawv ntawm ribbons nrog qhov sib txawv ntawm txhua qhov fiber ntau ribbon, qhov kev tsim no pab txhim kho lub zog tensile thiab lateral compression tsis kam ntawm lub cable.
3. Cov khoom siv ntxiv ntawm fiber-optic cables
Ntxiv rau qhov yooj yim kho qhov muag fibers, cladding thiab sheath, fiber optic cables yuav muaj cov nram qab no ntxiv Cheebtsam:
Lub zog tseem ceeb: Nyob rau hauv nruab nrab ntawm lub fiber optic cable, nws muab cov neeg kho tshuab ntxiv zog los tiv thaiv tensile rog thiab kev ntxhov siab.
Tsis txheej: Nyob nruab nrab ntawm cov fiber ntau thiab cov sheath, nws ntxiv tiv thaiv cov fiber ntau los ntawm kev cuam tshuam thiab puas.
Armouring txheej: Qee cov fiber ntau optic cables kuj muaj txheej txheej armouring ntxiv, xws li steel daim kab xev armouring, los muab kev tiv thaiv ntxiv rau qhov chaw hnyav lossis qhov yuav tsum tau muaj kev tiv thaiv ntxiv.
4. Kev tsim cov txheej txheem rau fiber-optic cables
Kev tsim khoom ntawmfiber ntau optic cablesMuaj cov txheej txheem siab precision, nrog rau cov kauj ruam xws li kev kos duab ntawm fiber ntau optics, txheej ntawm cladding, stranding, cable tsim thiab sheath extrusion. Txhua kauj ruam yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias qhov ua tau zoo thiab qhov zoo ntawm fiber ntau optic cable.
Nyob rau hauv cov ntsiab lus, tus qauv tsim ntawm optical fiber cables coj mus rau hauv tus account ob qho tib si kis tau tus mob ntawm optical signals thiab lub cev tiv thaiv thiab ib puag ncig adaptability. Nrog rau kev nce qib ntawm kev siv thev naus laus zis, cov qauv thiab cov ntaub ntawv ntawm fiber ntau optic cables tau ua kom zoo kom tau raws li qhov xav tau ntawm kev sib txuas lus.
