Kev ceev faj thaum siv FTTH
Nyob rau hauv qhov kev pom ntawm daim ntawv thov dav dav ntawm optical network yav tom ntej, nws muaj peev xwm los xyuas kom meej tias FTTH yuav dhau los ua tus qauv tseem ceeb ntawm kev txhim kho yav tom ntej.Qhov no, nws yuav tsum tau tsom mus rau kev tsim kho FTTH optical network, tshwj xeeb tshaj yog rau kev tsim kho nyob rau hauv theem ntawm Fiber-optic nkag, thiaj li ua kom tiav tag nrho lub hom phiaj ntawm kev txhim kho kev ua hauj lwm zoo thiab tag nrho cov ntaub ntawv kis tau tus mob network.
Hauv cov ntsiab lus, muaj ob lub ntsiab lus tseem ceeb uas yuav tsum tau pom hauv kev tsim kho ntawm FTTH fiber ntau rau tsev neeg.
Tso cov kab xaiv
Tam sim no siv rau FTTH sab hauv tsev kho qhov muag fiber ntau xaiv yog npauj npaim-zoo li tus optical fiber cable, uas tsuas yog hu ua npauj npaim optical cable.Hom fiber ntau optic no tuaj yeem muab faib ntxiv rau hauv cov kab hauv tsev thiab kev txhawb nqa tus kheej.Lawv yeej ib txwm zoo ib yam hauv cov qauv, nruab nrog cov tswv cuab txhawb zog thiab cov tsho ntawm ob sab ntawm fiber ntau.Qhov txawv yog tias tus kheej txhawb nqa optical cable nws tus kheej kuj tseem txuas nrog ib sab ntawm cov hlua dai, uas tuaj yeem txhim kho cov khoom siv kho qhov muag ntawm nws tus kheej.
Nyob rau hauv kev xaiv ntawm npauj npaim kho qhov muag cables, nws yuav tsum tau muab sau tseg hais tias nyob rau hauv lub sab hauv tsev thaiv cov khoom siv kho qhov muag cables yuav muab faib ua ob hom hlau reinforcing cov tswv cuab thiab cov uas tsis yog-hlau reinforcing tswv cuab raws li cov sib txawv reinforcing tswv cuab.Nyob rau hauv sib piv, cov uas tsis yog-hlau reinforcing tswv cuab yog npauj npaim optical cables.Lub zog txhua yam uas tuaj yeem ua siab ntev yog qhov me me, yog li thiaj li tsis ua rau muaj kev puas tsuaj rau cov tub ntxhais kho qhov muag fiber ntau, cov hlau txuas ntxiv cov kab hluav taws xob txuas hluav taws xob feem ntau yog siv, thiab cov khoom siv hluav taws xob uas tsis yog xim hlau txuas ntxiv butterfly optical fiber cable tsuas yog siv hauv lub sijhawm uas muaj qhov yuav tsum tau muaj kev tiv thaiv xob laim.
Tshem tawm cable installation
Kev ruaj ntseg ntawm lub tsev fiber ntau optic cable yuav tsum xav txog ob yam.Ib qho yog kev tiv thaiv ntawm optical cable nws tus kheej hauv cov txheej txheem nkag mus rau hauv tsev, thiab lwm yam yog txoj kev kho qhov muag cable hauv cov txheej txheem tso.
Rau yav dhau los, lub hom phiaj ntawm kev ua haujlwm yog nyob rau ntawm qhov chaw ntawm cov kav dej PVC, vim tias tsis yog txhua qhov kev nkag mus rau hauv lub tsev ib puag ncig, tab sis rau qhov chaw nkag tsis muaj ncej, PVC piping yog yuav tsum tau.Rau qhov xwm txheej no, nws yuav tsum xub muab sau tseg tias qhov tshwj xeeb ntawm cov yeeb nkab PVC tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov hlua, thiab qhov smoothness ntawm PVC yeeb nkab spout yuav tsum tau kuaj xyuas kom tsis txhob burrs lossis ntse npoo los ntawm kev puas tsuaj rau cable. PVC piping yuav tsum tsis txhob muaj cov kab nrib pleb lossis dents, thiab nws tuaj yeem ua lub luag haujlwm ntawm kev tiv thaiv nws sab hauv.
Rau qhov tom kawg, kev saib xyuas yuav tsum tau them rau cov neeg kho tshuab quab yuam uas lub optical cable yuav tsum tau dais.Lub hom phiaj tseem ceeb suav nrog ob lub zog tensile thiab lub zog crushing.Txhua hom cables qhia txawv cov kabmob muaj peev xwm. Feem ntau, cov khoom siv tsis yog hlau reinforcement built-in sab hauv tsev thaiv npauj npaim optical cables tuaj yeem tiv taus 40N tensile quab yuam thiab 500N / 100mm compaction quab yuam, thaum muaj ib tug hlau reinforced siv sab hauv tsev Wiring npauj npaim optical fiber cable tuaj yeem tiv taus 100N tensile quab yuam thiab 1000N / 100mm crushing quab yuam.Kev txhawb nqa tus kheej npauj npaim fiber ntau tuaj yeem tiv taus 300N tensile quab yuam thiab 1000N / 100mm crushing quab yuam.Hauv cov txheej txheem ua haujlwm tiag tiag, cov khoom siv kho qhov muag yuav tsum raug xaiv raws li qhov chaw ua haujlwm sib txawv.
Nyob rau hauv kev xaiv ntawm npauj npaim kho qhov muag cables, nws yuav tsum tau muab sau tseg hais tias nyob rau hauv lub sab hauv tsev thaiv cov khoom siv kho qhov muag cables yuav muab faib ua ob hom hlau reinforcing cov tswv cuab thiab cov uas tsis yog-hlau reinforcing tswv cuab raws li cov sib txawv reinforcing tswv cuab.Nyob rau hauv sib piv, cov uas tsis yog-hlau reinforcing tswv cuab yog npauj npaim optical cables.Lub zog txhua yam uas tuaj yeem ua siab ntev yog qhov me me, yog li thiaj li tsis ua rau muaj kev puas tsuaj rau cov tub ntxhais kho qhov muag fiber ntau, cov hlau txuas ntxiv cov kab hluav taws xob txuas hluav taws xob feem ntau yog siv, thiab cov khoom siv hluav taws xob uas tsis yog xim hlau txuas ntxiv butterfly optical fiber cable tsuas yog siv hauv lub sijhawm uas muaj qhov yuav tsum tau muaj kev tiv thaiv xob laim.
