Qhia Txog Kev Xaiv Txoj Cai Fiber Optic Cable
Cov kab hluav taws xob fiber ntau yog lub iav thawb iav heev uas los ntawm kev los ntawm cov hluav taws xob sib kis. Tam sim no, kab xaim hluav taws xob fiber ntau yog qhov xav tau cable nruab nrab vim nws qhov kev tiv thaiv kab mob rau kev xaim hluav taws xob (EMI) thiab xov tooj cua zaus cuam tshuam (RFI). Nws tuaj yeem thauj cov cim hluav taws xob rau cov chaw nyob deb, tsis hais hauv thaj chaw hauv nroog, thaj chaw dav, lossis hauv nroog loj. Tsab xov xwm no yuav qhia qee cov ntaub ntawv hais txog cov hlua hluav taws xob tua hluav taws xob cable thiab taw rau muab cov lus qhia ntawm kev xaiv txoj cai fiber ntau cable.
Cov kab hluav taws xob fiber ntau tuaj yeem faib ua ib hom fiber ntau cable thiab multimode fiber ntau cable. Ib hom kho qhov muag fiber ntau feem ntau muaj cov tub ntxhais txoj kab uas hla ntawm 9 µm thiab xav tau laser thev naus laus zis rau kev xa thiab txais cov ntaub ntawv. Nws tuaj yeem nqa lub teeb liab rau mais, uas ua rau nws zoo tagnrho rau cov xov tooj thiab cov chaw xa xov tooj cable. Raws li lub npe pom zoo, multimode fiber tso cai rau cov teeb liab taug kev hauv ntau hom, lossis txoj hauv kev, raws sab hauv ntawm cov iav strand lossis cov tub ntxhais. Muaj nrog fiber ntau cov diameters ntawm 62,5 µm lossis 50 µm. Txawm hais tias cov tub ntxhais qhov ntau thiab tsawg ntawm cov tib hom fiber ntau thiab ntau lub fiber ntau qhov sib txawv, ob qho tib si fiber ntau kawg nrog ib txoj kab sab nraud ntawm thaj tsam li 250 µm. Cov kev sib txawv tseem ceeb ntawm ob yam ntawm cov roj carbon fiber optic tau piav qhia meej ntxiv hauv lwm tsab xov xwm - Tib hom Fiber thiab Multimode Fiber: Qhov twg los xaiv?
Qhov sib txawv loj ntawm cov hluav taws xob sab hauv thiab sab nraum zoov hluav taws xob cable yog thaiv cov dej. Ib qho txuas hniav twg yog ib hnub yuav muaj noo noo nyob rau hauv nws. Cov kab hluav taws xob sab nraud tau tsim los tiv thaiv cov fibers ntawm xyoo ntawm kev ya raws. Cov hlua hluav taws xob sab hauv tsev yog qhov peb hu ua “cov yeeb yaj kiab sib txuas”, qhov chaw ntawm cov iav fiber muaj thawj txheej thiab cov xov txheej thib ob uas ua rau txhua qhov fiber ntau txog 900 microns - li 1mm lossis 1/25-nti, ua kom muaj fiber ntau yooj yim ua haujlwm nrog.
Feem ntau, cov nyob sab hauv tsev muaj xws li yooj yim thiab zipcord, faib cov kab hluav taws xob thiab cov xov hluav taws xob tawg. Simplex fiber optic cables yog ib qho fiber ntau, kaw ntom ntom (coated nrog 900 micron tsis dhau lub thawj tsis dhau txheej) nrog Kevlar (aramid fiber) muaj zog cov tswv cuab thiab cov tsho rau sab hauv tsev. Lub tsho yog feem ntau li 3 hli (1/8 in.) Txoj kab uas hla. Zipcord tsuas yog ob qho kev sib koom tes no nrog lub vev xaib nyias. Nws siv feem ntau rau thaj qaum thiab daim phiaj nraub qaum, tab sis zipcord tseem tuaj yeem siv rau kev sib txuas desktop.
Kev faib tawm fiber ntau kho qhov muaj cov hlua ua rau ntau txoj hlua khi ua kom nyob hauv qab ntawm tib lub tsho nrog Kevlar lub zog thiab qee zaum fiberglass rob qhov cuab lub zog txhav txhav rau hauv lub cable thiab tiv thaiv kinking. Cov xaim hluav taws xob no muaj me me hauv qhov loj me, thiab siv rau kev siv ua luv luv, qhuav sib dhos, riser thiab plenum kev siv. Cov xaim yog ob txoj hauv kev thiab muaj peev xwm txiav ncaj qha, tab sis vim tias lawv cov fibers tsis yog ib tus kheej lub zog, cov kab hluav taws xob no yuav tsum tau tawg tawm nrog "lub thawv tawg" lossis txiav tawm sab hauv lub vaj huam sib luag los yog lub thawv hlws ris. Qhov xa xov hluav taws xob yog cov cable nrov tshaj plaws rau siv sab hauv.
Breakout fiber ntau cov kab ua tau ua los ntawm ob peb lub xov txuas yooj yim ua ke nyob rau sab hauv ib lub tsho yooj yim kom yooj yim hauv kev rub thiab ruggedness. Qhov no yog qhov muaj zog, cov qauv zoo nkauj, tab sis muaj qhov loj dua thiab kim dua li ntawm cov xa hluav taws xob. Lawv haum rau cov kab khiav, kev siv riser thiab plenum, thiab zoo tagnrho rau kev siv qhov twg ruggedness tseem ceeb lossis hauv qhov chaw uas tsuas yog ib lossis ob daim ntawm cov khoom siv xav tau txuas nrog.
Fiber optic cable nyob rau sab nraum zoov daim ntawv thov yuav tsum muaj kev tiv thaiv ntau dua los ntawm dej ingress, vermin thiab lwm yam mob tau ntsib hauv av. Cov xov hluav taws xob sab nraud xav tau txais kev muaj zog ntxiv rau kev rub kom deb. Feem ntau, cov hlua hluav taws xob fiber optic ntsia rau hauv kev siv sab nraum zoov muaj cov xoob xoob fiber ntau cable, xov kab fiber ntau optic cable, armored fiber ntau optic cable thiab aerial fiber ntau cable.
Loose tube fiber optic cables muaj nyob rau ntawm cov xov sib txuas ua ke sab hauv lub taub yas me me, uas yog nyob rau hauv lem qhov txhab ib puag ncig lub zog nruab nrab cov tswv cuab thiab cov tsho, muab me me, siab fiber ntau suav cable. Lawv tsim nyog rau cov ntaub ntawv cog ntoo rau sab nraud vim lawv tuaj yeem ua nrog cov xoob xoob uas muaj cov roj gel lossis dej nqus cov hmoov kom tiv thaiv kev puas tsuaj rau cov kab ntawm cov dej. Txij li cov fibers tsuas muaj nyias txheej tsis, lawv yuav tsum ua kom zoo thiab tiv thaiv kom tsis txhob puas. Lawv tuaj yeem siv hauv cov pob zeb, khov sab saum taub hau lossis cog ncaj qha rau hauv av.
Ribbon fiber optic cables muaj qhov siab tshaj plaws ntawm cov khoom ntim raws li tag nrho cov fibers raug nteg hauv kab, feem ntau ntawm 12 fibers, thiab nteg rau saum toj ntawm txhua lwm yam. Ua li no, 144 daim phiaj tsuas yog muaj ntu ntu ntawm li ntawm 1/4 nti lossis 6mm. Qee cov qauv siv cable siv ib qho slotted tseem ceeb nrog mus txog 6 ntawm cov 144 fiber ntau cov kab xov coj los ua ke rau 864 fibers hauv ib cable. Vim tias lawv nyob sab nraud cog cov kab hluav taws xob, lawv tau sau cov dej rau thaiv dej.
Cov tub rog armored fiber optic raug teeb tsa los ntawm qhov faus ncaj qha rau hauv thaj chaw uas muaj nas cov teeb meem. Feem ntau lawv muaj cov hlau thaiv ua ke nyob nruab nrab ntawm ob lub tsho tiv thaiv txhawm rau tiv thaiv kev chob. Qhov no txhais tau hais tias lub cable yog conductive, yog li nws yuav tsum tau muab av kom zoo. Nws yog qhov zoo tshaj plaws los xaiv cov khoom siv roj carbon fiber optic cable thaum siv cable ncaj qha rau sab nraum zoov. Aerial fiber optic cables tuaj yeem lashed rau tus neeg xa xov lossis lwm lub cable (muaj sib txuam hauv CATV) lossis muaj hlau lossis aramid lub zog cov tswv cuab kom lawv txhawb lawv tus kheej. Aerial cables yog rau sab nraud nruab ntawm ncej.
Cov hlua hluav taws xob fiber ntau tuaj yeem muab lub zog, kev ncaj ncees thiab kev tiv thaiv tag nrho ntawm cov koom fiber ntau. PVC yog dav siv raws li lub tsho cable rau ntau daim ntawv thov - khoos phis tawj, kev sib txuas lus, xov hluav taws xob qis, thiab lwm yam. cov khoom siv hluav taws xob. OFNP, lossis pleets plev, haum rau kev siv hauv thaj chaw plenum xws li chaw ua kom dej nteg lossis hauv pem teb. Ntau lub chaw xa cov ntaub ntawv thiab chav pw hauv chav tsev muaj cov tseev kom muaj rau plenum-rated cables. LSZH yog lub tsho ua los ntawm cov sib txuas tshwj xeeb uas muab cov pa luam yeeb me me thiab tsis muaj cov pa phem halogenic sib txuas thaum hlawv tawm.
Kuv siv hom fiber ntau cable them twg? Thaum xaiv cov roj carbon fiber optic, thov nco ntsoov cov ntsiab lus uas tau hais hauv hauv tsab xov xwm no. Tsuas yog ua kom pom tseeb rau txhua yam no tuaj yeem koj xaiv cov fiber ntau optic cable uas feem ntau haum rau koj daim ntawv thov. Yog tias koj tseem tsis meej pem txog qhov twg los xaiv, koj tuaj yeem mus ntsib www.focc-fiber.com lossis hu rau focc@fiberfocc.com kom nrhiav kev pab raws li ntau cov tswv yim kev tshaj lij tuaj yeem muab los ntawm pab pawg FOCC.
