Cov khoom siv xoob ntawm lub optical cable nws tus kheej muaj hydrolysis tsis kam thiab siab zog. Lub raj yog ntim nrog cov roj tshwj xeeb, muab kev tiv thaiv tseem ceeb rau cov fibers optical. Cov tswv cuab lub zog yog nyob rau hauv nruab nrab ntawm cov tub ntxhais cable, thiab cov raj xoob yog tso tseg nyob ib ncig ntawm cov tswv cuab lub zog nrog qhov tsim nyog nteg ntev. Los ntawm kev tswj cov fiber ntau ntev thiab kho qhov kev sib tw, cov khoom siv kho qhov muag tuaj yeem ua tiav lub zog tensile zoo thiab cov yam ntxwv kub. Qhov chaw nruab nrab ntawm cov raj xoob thiab cov tswv cuab lub zog tau ntim nrog cov kab gel thiab tso tseg ua ke, ua kom cov dej tsis zoo ntawm cov hlab ntsha xoob thiab cov tswv cuab lub zog.
Lub radial thiab longitudinal waterproofing ntawm optical cable yog guaranteed los ntawm ntau yam kev ntsuas:
Cov kab hluav taws xob kho qhov muag yog tsim los ntawm cov txheej txheem ncaj qha rau 250 μm txoj kab uas hla UV- kho thawj coated fiber ntau nrog cov khoom siv los ua 900 μm nruj- buffered fiber. Siv cov nruj- buffered fiber ntau ua ib chav tsev, cov ntaub ntawv tensile tsim nyog tau muab tso rau ib ncig ntawm ib los yog ntau dua nruj- buffered fibers, thiab cov nplaim hluav taws kub - cov khoom siv hluav taws xob retardant yog extruded los ua ib qho -core lossis multi-core optical cable.
Cov yam ntxwv tseem ceeb ntawm cov kab hluav taws xob kho qhov muag yog raws li hauv qab no: Cov cuab yeej tshwj xeeb yog siv los kho qhov nruj ntawm cov txheej txheem kom tau txais kev pom zoo fiber ntau stripping kev ua tau zoo thiab cov khoom siv kho qhov muag. High-modulus aramid fibers yog siv los ua cov khoom siv zog tensile, thiab qhov nro ntawm aramid fibers yog tswj tau los muab cov khoom siv kho qhov muag zoo heev tensile mechanical zog. Lub plhaub sab nrauv siv cov nplaim hluav taws- cov khoom siv hluav taws xob kom ua tau raws li qhov xav tau ntawm hluav taws kub sib txawv.
