Cov kab hluav taws xob fiber ntau siv rau hauv kev tsim kho ntawm cov tes hauj lwm rau kev xa cov ntaub ntawv. Nyob rau tib lub sijhawm, cov kab fiber ntau tuaj yeem ua los ntawm ntau cov ntaub ntawv thiab siv txhua yam thev naus laus zis uas txiav txim siab qhov zoo ntawm cov cable thiab nws cov tawm.
Tus naj npawb ntawm cov mods
Qhov kev xaiv ntawm cable yuav tsum tau ua raws li lub hom phiaj rau cov kab ntawd. Yog tias koj xaiv ib txoj xaim rau tso pob txha caj qaum, koj tuaj yeem yuav ib yam khoom nrog xaim lossis cable pab. Xws li cov cable muaj ib hom fiber ntau, cov xov tooj tuaj yeem pib ntawm 16 thiab xaus nrog 48. Tsis tas li, ib hom xov hlau tau muaj cov chaw ua haujlwm ntau dua thiab cov ntaub ntawv xa mus deb, uas txhais tau tias thaum tso caj qaum, tag nrho tus nqi ntawm lub installation yuav qis dua ntau tshaj qhov ntawm multimode. Ib-hom cable feem ntau yog siv rau tso xov tooj network thiab cable TV.
Multimode cables muaj peev xwm xa cov ntaub ntawv ntau hauv ntau yoj, uas yog nws cov txiaj ntsig tseem ceeb. Xws li cov khoom lag luam tau siv rau hauv kev tsim kho ntawm cable Internet network. Multimode fiber yuav pab muab cov ntaub ntawv cov nqi siab dua li ntawm ib leeg fiber ntau. Txawm li cas los xij, cov xov hlau multimode poob qis hauv kev ua tau zoo thiab lawv siv tsis tau ncaj ncees yog tias koj xav nteg cov network uas ntev tshaj 400 m.
Cov yam ntxwv ntawm cable
Muaj kev tiv thaiv nrog hom cable, nws yog qhov tsim nyog los txiav txim siab qhov tsim nyog uas yuav tsum tau rau lub cable network. Thaum xaiv cov khoom lag luam, nws yog qhov tseem ceeb yuav tsum them sai sai rau cov yam ntxwv xws li kev thauj khoom poob siab, uas yog qhov taw qhia ntawm kev tiv thaiv ntawm cov hlau thiab nws cov tub ntxhais los ntawm kev poob siab. Lwm qhov tseem ceeb ntawm qhov tseem ceeb yog qhov tso cai khoov, uas qhia qhov siab tshaj plaws yuav tsum muaj hluav taws xob ntawm curvature ntawm cov hlau. Nws yog ib qho tseem ceeb tias daim duab no yog siab dua yog tias koj npaj yuav nruab los ntawm kev lim dej ntawm tes, kev xa hluav taws xob lossis kab hluav taws xob cable.
Kev tsis saib xyuas ntawm qhov ntsuas no tuaj yeem ua rau qhov kev ua txhaum ntawm kev ncaj ncees ntawm lub teeb taw qhia ntawm cov hlau thiab ua rau cov khoom lag luam poob. Lwm tus yam ntxwv tseem ceeb ntawm cov hlau yog twist (qhov degree ntawm kev tiv thaiv ntawm fiber los ntawm sheath ntawm cov cable) thiab tiv thaiv kev ya raws nkag mus rau hauv lub cable, uas yuav dhau los ua qhov tseem ceeb yog tias koj siv cov hlau nyob sab nraud.
Qhov kev xaiv ntawm cable yuav tsum tau ua raws li qhov chaw siv. Piv txwv, qhov kho qhov muag hluav taws xob rau chav tsev yuav tsum muaj kev tiv thaiv hluav taws thiab tsis muaj dej tawm, kom thaum cov cua sov tsis hloov nws cov qauv thiab tom qab ntawd tsis kis.
Rau kev siv sab nraum zoov, cov cuab yeej siv thiab tuab txheej ntawm fiberglass yuav yog ib qho ntxiv, uas yuav tiv thaiv tau cov xov los ntawm kev cuam tshuam sab nraud. Nws tseem yog ib qho tseem ceeb uas xws li lub cable muaj qhov txo coefficient ntawm kev sib txhuam, nrog rau kev tiv thaiv sab hauv thiab sab nraud polyethylene. Cov yam ntxwv no tau ua tiav los ntawm kev thov cov ntaub ntawv ntxiv rau cov hlau.
