Tawm Cable thiab nws txoj kev txiav nyob rau hauv FTTH
Tawm kab, raws li ib feem tseem ceeb ntawm FTTH network, cov ntaub ntawv qhov kawg sab nraud ntawm tus neeg muaj npe thiab lub ciav hlau tawm. Xaiv txoj cai FTTH drop cable txiav los yog kev sib txuas lus sib txuas lus yuav cuam tshuam rau cov kev ruaj ntseg network, ua haujlwm yooj yim thiab kev lag luam ntawm FTTH xa mus. Li ntawd, ntawm ob lub FTTH nco cable txiav txoj kev: splice vs connector, uas yuav tsum tau koj xaiv? Yuav ua li cas yog qhov zoo thiab cov kev xav ntawm txhua txoj kev txiav tawm?
Dab Tsi Yog Dab Tsi?
FTTH poob cables, raws li tau hais yav tas los, nyob ntawm tus neeg xaus rau cov neeg txuas mus txuas rau lub davhlau ya nyob twg ntawm ib qho kev xa xov hluav taws xob mus rau ib tus neeg siv thaj chaw. Cov kab no feem ntau me me, tsis muaj fiber ntau cov cab cab uas tsis tshua muaj kev txwv, tsis tuaj yeem ua rau nruab aerially, underground lossis faus. Raws li nws raug siv rau sab nraum zoov, poob cable yuav tsum muaj tsawg kawg nkaus rub zog ntawm 1335 Newtons raws li kev lag luam tus qauv. Fiber optic nco cables muaj nyob rau ntau ntau hom. Feem ntau ntawm cov kab mob qaub ncaug feem ntau yog cov kab nres poob, kab-8 aerial poob cable thiab hloov kab.
Caij Nyiab Teeb Cable
Tig poob cable, nrog lub tiaj tiaj tawm, feem ntau muaj ib lub hnab tawv nqaij ntawm polyethylene, ntau lub fibers thiab ob lub tswv yim dielectric cov tswv cuab kom muab cov ntsuas siab ua haujlwm. Fiber ntau cable feem ntau muaj ib los yog ob daim txiag, tab sis, cov cab cab uas muaj fiber ntau suav mus txog 12 los yog ntau tshaj ntawd kuj muaj tam sim no. Cov duab hauv qab no qhia tau hais tias qhov ntu tshuav ntawm ib lub dav hlau poob nrog 2 fibers.
Daim duab-8 Huab Tos Cable
Daim npav-8 aerial poob cable yog nws tus kheej-txhawb cable, nrog lub xov tooj uas ruaj khov rau hlau hlau, tsim rau kev yooj yim thiab yig kev lag luam kev lag luam rau cov kev siv rau sab nraum zoov. Hom fib fib ntaus kab no yog tsau rau cov hlau hlau raws li pom hauv daim duab hauv qab no. Cov nplaum fiber ntau ntawm cov duab-8 poob cable yog 2 mus rau 48. Cov kev ceev ceev yog feem ntau 6000 Newtons.
Round Tee Cable
Hloov cov kab poob qis feem ntau muaj ib zaug xwb uas tsis muaj khoov-qhov tsis muaj zog thiab cov neeg nyob hauv dielectric zog thiab ib lub tsho sab nraud, uas muaj peev xwm ua kom muaj taus thiab muaj kev cia siab rau txoj kev poob qis ntawm lub network. Cov nram qab no qhia txog seem ntu ntawm kab ib kab zom zaws nrog ib qho ntom ntom tau qhov muag fais fab.
FTTH Tshem Tawm Kab Caws Taw: Splice lossis Connector?
Nws yog tsim nyog yuav tau xaiv txoj cai fiber ntau optic rau FTTH network los ntawm tag nrho. Txawm li cas los xij, FTTH poob cable ua qhov kawg kev txuas los ntawm cov vas sab fiber optic rau cov neeg siv khoom kuj tseem ceeb heev. Yog li, nrhiav kev yooj yim, txuag thiab qis qis FTTH poob qis kab txiav tawm ua ib qho tseem ceeb heev ntawm qhov kev pab cuam broadband. Raws li tau hais hauv thawj kauj ruam, muaj ob txoj kev FTTH poob qis kab kev txiav tawm: splice thiab connector. Tsuas hais lus xwb, thooj li hais txog kev sib txuas ntawm kev sib txuas lus, thaum siv txoj kev sib txuas lus tau yooj yim mated thiab un-mated los ntawm tes.
Splice vs Connector: Txhua tus muaj nws Pros thiab Cons
Nws yog lub npe hu tias splice, uas tshem tawm cov teeb meem ntawm kev sib tshuam ua ke los yog khib nyiab nrog ib qho chaw ruaj khov, muaj kev kho qhov muag zoo tshaj qhov muaj fiber optic connector. Txawm li cas los xij, tsis tuaj yeem ua hauj lwm yooj yim dua piv txwv nrog fiber optic connector. Fiber optic connector yuav muab ib qho chaw nkag rau kev sib tham uas tsis tuaj yeem muab los ntawm kev sib txuas lus. Ob txoj kev muaj lawv tus kheej pros thiab cons.
Feem ntau, muab cais tawm rau FTTH poob cables nyob rau qhov chaw uas tsis muaj teeb meem rau yav tom ntej, xws li greenfield, daim ntawv thov tshiab uas tus kws kho mob muab tau yooj yim txhawm rau tag nrho cov cab cab. Fiber optic connector yog qhov tsim nyog rau cov ntawv thov uas yuav tsum tau yooj yim, xws li ONTs uas muaj ib qho interface connector.
Xaiv Txoj Kev Xaiv Txoj Cai
Rau FTTH poob qws cable, nws muaj ob txoj kev. Ib qho yog fusion splicing, thiab lwm yam yog mechanical splicing. Fusion splice tau raug muab pov thawj los muab ib txoj kab zoo siab uas tsis tshuav zoo siab thiab xav txog. Txawm li cas los, thawj cov kev siv nyiaj, kev tswj cov nqi thiab qeeb installation ceev ntawm fusion splicing tabkaum nws cov xwm txheej raws li qhov kev xav zoo tshaj plaws. Txhua tus neeg ua hauj lwm splicing yog siv hauv FTTH nco cable installation hauv lub teb chaws, raws li cov neeg ua hauj lwm lem tau ua tiav daim teb los ntawm kev siv cov cuab yeej yooj yooj yim tes thiab pheej yig dua txhua yam khoom (qhia hauv daim duab nram qab no) hauv 2 feeb.
Xaiv Txoj Kev Taw Qhia
Rau fiber ntau optic connector, muaj ob hom kev sib txuas rau FTTH nco cable txuas. Teb chaw txuas, uas muaj fuse-on connector thiab mechanical connector, thiab ua ntej poob cable, uas yog lub Hoobkas haujlwm nrog connector kawg ntawm kev xa xov cable.
Fuse-on connector siv tib lub tshuab ua fusion splicing los muab cov kev sib txuas ntawm qhov muag siab siab. Txawm li cas los xij, nws yuav tsum tau siv cov khoom kim heev thiab cov kws txawj ntse, thiab ntau lub sijhawm zoo li fusion splicing. Mechanical connector yuav yog qhov hloov ntawm lub fuse-on connector (muaj nyob rau hauv daim duab nram qab no), yog hais tias tus mob tsis haum rau cov uas hais. Nws yuav yog ib lub sij hawm-tseg thiab txuag nyiaj tov rau kev tshem tawm cov kab mob nres.
Yog tias koj tsis muaj kev txwv thiab xav tau kev ua haujlwm tsis zoo hauv ib lub sij hawm zoo tshaj, kev poob qab ua ntej yuav poob yog qhov koj xaiv. Muaj ntau cov khoom lag luam tuaj yeem muab koj tus cab xa mus rau ntau hom fiber ntau, fiber optic connector thiab ntev.
