Optical cable qauv
Raws li lub xeev ntawm cov coated optical fiber nyob rau hauv lub kho qhov muag cable, optical cable muaj ob hom: nruj qauv thiab xoob qauv. Skeleton cable yog ib qho qauv xoob. Optical fiber yog faus rau hauv qhov helical groove nyob rau sab nraud ntawm lub cev pob txha, thiab muaj chaw rau kev txav mus los. Hom kab hluav taws xob kho qhov muag no muaj cov yam ntxwv zoo dua ntawm kev sib cais sab nraud quab yuam thiab tiv thaiv micro-bending poob. Stranded optical fiber cable yog cov qauv nruj nruj thaum siv cov fiber ntau kaw ntom nti, thiab cov coated optical fiber yog nruj nreem qhwv hauv cov qauv cable, tab sis thaum stranded optical fiber cable siv xoob qhwv optical fiber ntau, cov khoom siv kho qhov muag tuaj yeem txav mus rau theem nrab. coated yas raj. , tseem yog ib tug xoob qauv. Cov txheej txheem cabling ntawm stranded optical cable yog qhov yooj yim thiab kev ua tau zoo. Tsis tas li ntawd, tseem muaj cov qauv tsim xws li ribbon cable thiab ib leeg-core cable.
Muaj kev txhawb nqa hauv txhua yam ntawm cov kab hluav taws xob kho qhov muag kom nqa qhov nro. Nws yog tsim los ntawm cov ntaub ntawv muaj zog nrog siab elastic modulus, feem ntau siv yog steel hlau, siab zog iav fiber ntau thiab high-modulus hluavtaws fiber aramid. Qhov kev txhawb zog ua rau cov kab hluav taws xob kho qhov muag tsuas yog qhov tsis tshua muaj elongation deformation (piv txwv li, tsawg dua 0.5 feem pua ) nyob rau hauv kev ntxhov siab ntawm kev siv, thiaj li tiv thaiv cov fiber ntau optical los ntawm kev ntxhov siab lossis tsuas yog dais qis heev rau tiv thaiv cov fiber ntau optical los ntawm kev tawg.
Cov qauv sheath thiab cov khoom siv ntawm cov khoom siv kho qhov muag yog nyob ntawm kev siv ib puag ncig thiab cov kev xav tau, thiab yog qhov pib zoo ib yam li cov cable hauv tib yam kev siv. Raws li kev siv ib puag ncig ntawm cov khoom siv kho qhov muag, muaj cov khoom siv hluav taws xob siv hluav taws xob, cov kab hluav taws xob ncaj qha faus, submarine optical cables, teb optical cables, thiab lwm yam.
