Kev ceev faj rau xaiv cov kab hluav taws xob sab nraum zoov

Sab nraum zoov optical cables muaj lub zog tensile siab, tuab thiab hnyav tiv thaiv txheej, thiab feem ntau yog armored (xws li hlau qhwv). Sab nraum zoov optical cables yog tsim nyog rau kev sib txuas ntawm cov tsev thiab cov chaw taws teeb.
Kev siv ib puag ncig ntawm cov kab hluav taws xob sab nraum zoov yog sab nraum zoov thiab yuav tsum muaj dej tsis zoo. Feem ntau, cov ntaub qhwv sab nrauv siv yog ua los ntawm cov khoom siv PE, thiab nws cov qauv sab hauv feem ntau muab faib ua cov qauv hauv nruab nrab thiab txheej txheej twisted.
Los ntawm qhov muag liab qab, cov ntaub qhwv hauv tsev thiab sab nraum zoov feem ntau yog ua los ntawm cov khoom siv daj lossis txiv kab ntxwv PVC, thaum lub tsho sab nraum zoov yog ua los ntawm cov khoom siv PE dub. Qhov sib txawv ntawm cov qauv yog tias sab nraum zoov sheaths feem ntau muaj lo lus GY.
Sab nraum zoov kho qhov muag cable: Cov ntim sab nrauv yog tuab thiab muaj qee yam khoom siv thiab ib puag ncig xws li kev ua haujlwm siab, tiv thaiv corrosion, thiab tensile lub zog.
Sab hauv kho qhov muag cable: feem ntau yog siv sab hauv tsev, nrog rau cov yam ntxwv tseem ceeb ntawm kev khoov yooj yim thiab tuaj yeem siv rau hauv qhov chaw nqaim thiab lwm qhov chaw. Qhov thib ob, nws yuav tsum muaj cov yam ntxwv sab nraud xws li hluav taws kub nyhiab, nplaim retardancy, tensile zog, thiab softness.
Sab nraum zoov kho qhov muag cable yog ib txoj kab kev sib txuas lus uas ua tiav cov kev sib kis ntawm cov teeb liab kho qhov muag. Cov tub ntxhais cable yog tsim los ntawm qee tus naj npawb ntawm cov khoom siv kho qhov muag hauv ib txoj hauv kev, nrog rau cov ntaub qhwv los yog txheej txheej tiv thaiv.
Sab nraum zoov kho qhov muag cable yog tsim los ntawm Optical fiber (iav fiber ntau li nyias li cov plaub hau), lub tes tsho tu yas thiab yas sheath. Tsis muaj kub, nyiaj, tooj liab, txhuas thiab lwm yam hlau nyob rau hauv optical cable.
Feem ntau hais lus, sab hauv tsev thiab sab nraum zoov cov khoom siv kho qhov muag tsuas yog sau nrog cov khoom sib txawv xws li muab tub lim, cov khoom siv ntxiv, thiab cov ntaub qhwv. Piv txwv li, thaum ncaj qha faus rau sab nraum zoov kho qhov muag cables, armored optical cables yuav tsum tau xaiv. Thaum siv nyiaj siv ua haujlwm, lub hnab yas dub sab nrauv nrog ob lossis ntau dua cov hlua khi tuaj yeem siv rau cov khoom siv kho qhov muag. Thaum xaiv cov kab hluav taws xob sab hauv tsev, yuav tsum tau them nyiaj rau lawv cov nplaim hluav taws xob, tshuaj lom, thiab cov yam ntxwv ntawm cov pa taws. Feem ntau, nplaim-retardant tab sis tsis haus luam yeeb hom (Plenum) tuaj yeem xaiv tau hauv cov kav dej lossis qhov chaw ua pa. Nyob rau hauv qhov chaw raug, nplaim taws, tsis muaj tshuaj lom, thiab tsis muaj pa taws (Riser) yuav tsum tau xaiv. Qhov kev ncua deb ntawm lub transmitter mus rau lub receiver yog li 5 mais. Qhov muaj nyob ntawm kev taug qab kuj tseem cuam tshuam los ntawm hom thiab qhov zoo ntawm cov khoom xa / tau txais; Qhov muaj zog lub teeb qhov chaw, qhov ntau rhiab ntawm lub receiver, thiab qhov deb ntawm qhov chaw. Kev tshawb fawb tau pom tias bandwidth ntawm multimode fiber ntau yog kwv yees li 4000Mb / s. Cov tub ntxhais ntawm ib hom kev kho qhov muag fiber ntau yog nyias nyias, tso cai rau lub teeb tawm ncaj qha mus rau qhov chaw. Qhov kev ncua deb ntawm ib leeg-hom sab nraum zoov kho qhov muag cable teeb liab yog me dua li ntawm multimode optical cables.
Yog li ntawd, qhov kev txiav txim siab tshaj plaws rau kev xaiv multimode lossis ib hom yog nyob deb. Yog tias ze, multimode nyiam vim tias LED emitters / txais yuav tsum tau lasers pheej yig dua li ib hom. Yog tias qhov kev ncua deb loj, ib hom fiber ntau yog qhov zoo tshaj plaws. Yog tias xa cov ntaub ntawv loj bandwidth, ib hom yog qhov kev xaiv zoo tshaj plaws. Feem ntau hais lus, kev txheeb xyuas ntawm lub tsho sab nrauv ntawm cov khoom siv kho qhov muag yog raws li nram no: G.651 yog ib hom fiber ntau, G.652, G.653, G.654, thiab G.655 yog ib hom fibers. Cov xim ntawm tus Tsov tus tw fiber kuj tuaj yeem paub qhov txawv. Feem ntau, txiv kab ntxwv yog ib hom fiber ntau, thiab daj yog ib hom fiber ntau.
