FTTH Fiber Drop Cable - Kev siv sab hauv tsev & sab nraum zoov

Hais txog FTTH Drop Cable

FTTH nco cable muaj 1 mus rau 4 xim singlemode optical fibers nrog 250 µm ib tus zuj zus, uas muab kev daws teeb meem zoo rau fiber ntau rau lub tsev kawg mais kev daws teeb meem. Lub cable muaj ob lub Fiber Reinforced Plastic (FRP) lub zog cov tswv cuab thiab Low Smoke Zero Halogen (LSZH) tsho nrog nominal dimension 2 x 3 mm. Lawv ua tau raws li RoHS cov qauv. Nrog nws txoj kab uas hla me me, lub teeb yuag thiab cov qauv tshwj xeeb, nws yog ib qho yooj yim siv, tuav thiab rub cov fibers tawm ntawm cov cables. Nws yog qhov kev xaiv zoo tshaj plaws rau kev teeb tsa ncaj qha rau hauv tsev.

Nta & Cov txiaj ntsig

Kev xaiv hom fiber ntau

Singlemode optical fiber ntsib ITU-T G.657A1 lossis ITU-T G.657A2 tus qauv

Yuav Ua Li Cas Xaiv Txoj Cai LSZH Jacket?

Koj tuaj yeem xaiv lub tsho LSZH dawb rau siv sab hauv tsev thiab lub tsho LSZH dub rau sab nraum zoov siv nyob rau hauv luv luv. Rau cov cables dawb uas tau teeb tsa qhov twg lawv yuav nyob rau hauv lub hnub ncaj qha rau lub sijhawm ntev yuav tsum tau hloov ntau zaus. Yog li peb yuav tsum xaiv LSZH tsho dub rau lawv yog UV- tiv taus.

Kev siv sab hauv thiab sab nraum zoov

Muaj peb daim ntawv thov ntawm FTTH nco cables: sab hauv FTTH daim ntaub ntawv kab rov tav thiab riser, clipping rau tej chaw xws li skirting boards, thiab luv luv sab nraud siv nrog dub LSZH tsho. Vim lub sij hawm thiab qhov chaw txwv, kab lus no feem ntau yuav qhia txog kab rov tav thiab riser cabling rau FTTH daim ntaub ntawv, uas muab qhov tseem ceeb heev rau FTTH cabling.

Kab rov tav kab

Tso cable tag nrho cov dielectric rau Fiber Rau Lub Tsev (FTTH lossis FTTx) daim ntawv thov, qhov no txhais tau tias peb xav tau intrabuilding conduit. Conduit tuaj yeem ua los ntawm cov raj hlau los yog cov polyvinyl nruj -chloride yas. Kev khiav dej num yuav tsum txwv rau 100 ko taw, tsis pub ntau tshaj ob 90-degree khoov ntawm rub cov ntsiab lus lossis lub thawv. Nws khiav tuaj yeem ua rau hauv qab nthab lossis phab ntsa lossis hauv pem teb.

Txhawm rau siv FTTH fiber ntau poob cable, peb xav tau lub thawv rub. Lawv raug ntsia rau nuv ntses qhov khiav thiab looping lub cable rau ntev ntev ntawm conduit. Rub lub thawv tsis yog siv rau splicing cable. Ntses tapes los yog rub hlua yuav tsum tau muab tso rau hauv lub raj kom yooj yim installation. Sab hauv duct yog ib qho cuab yeej zoo heev rau kev tiv thaiv cable thiab ua kom yooj yim rau kev teeb tsa yav tom ntej.

Riser Kab

Droptical fiber ntau cables npaj rau daim ntawv thov ntsug muaj ib tug xam qhov siab tshaj plaws ntsug nce nqi muab rau lawv. Qhov nce ntsug yog qhov kev ncua deb ntawm lub cable yuav raug rub tawm vertically ua ntej kev txhawb nqa. Nws yog txiav txim los ntawm qhov hnyav ntawm lub cable thiab nws lub peev xwm los tiv thaiv buckling los yog kinking.

Koj tuaj yeem siv cais cov hlau mesh grips los rub cable vertically. Cov cuab yeej ua haujlwm zoo li pob tawb lossis ntiv tes tuav, txhawb nqa lub cable yam tsis tau tsoo cov tub ntxhais. Cables yuav tsum tau txais kev txhawb nqa los ntawm cov hlua khi, cov hlua khi los yog cov hlua khi hauv cov hlua khi. Thaum twg los tau, pib lub installation los ntawm sab saum toj, cia lub luj ntawm lub cable los pab lub rub es tsis txhob ntxiv load.
