Kev ua tau raws li cov qauv no pab ua kom muaj kev sib raug zoo ntawm ntau yam khoom siv thiab txo qhov ua tau ntawm cov teeb meem loj ntawm lub kaw lus.

Qhov no muaj tseeb tshwj xeeb thaum ua haujlwm hla ntau hom lag luam lossis thaum qhia cov cabling tshiab rau hauv cov chaw tsim kho uas twb tau tsim lawm.

Kev Ua Raws Cai thiab Kev Nyab Xeeb

Cov cai tswjfwm kev nyab xeeb thiab kev ua raws li txoj cai suav nrog cov ntaub ntawv siv thiab cov txheej txheem tsim cov xov hluav taws xob fiber optic. Cov xov hluav taws xob siv rau hauv kev teeb tsa sab hauv tsev yuav tsum ua raws li cov qauv tiv thaiv hluav taws.

Hauv Tebchaws Meskas, lawv yuav tsum ua raws li NEC (National Electrical Code) cov kev ntsuas rau kev tso pa tawm. Qhov no ntxiv ua rau muaj kev nyab xeeb ntxiv los ntawm cov xwm txheej txaus ntshai uas muaj nyob rau hauv qhov chaw kaw. Kev tiv thaiv UV thiab kev tiv thaiv dej yog qhov xav tau hauv cov xov hlau sab nraum zoov, tiv thaiv cov xov hlau tiv thaiv ntau yam ib puag ncig.

Ua raws li cov cai no yog qhov tseem ceeb rau kev tiv thaiv cov neeg siv thiab cov khoom siv ib yam nkaus thiab yog li ntawd tsis yog rau kev sib tham, txawm tias nyob rau ntawm qhov project txias tshaj plaws.

Qhov Tseem Ceeb ntawm Kev Ntsuas Los Ntawm Sab Nraud

Peb qhov kev kuaj xyuas los ntawm cov neeg sab nraud ua kom peb cov fiber optic cables tsis yog tsuas yog ua tau raws li, tab sis tshaj qhov qauv kev lag luam.

Cov koom haum nrog Fiber Optic Association (FOA) yog qhov xav tau los pab txhawb lub luag haujlwm no. Tsim los ntawm cov kws tshaj lij uas muaj ntau tshaj 20 xyoo ntawm kev paub, cov ntawv pov thawj FOA yog tus qauv kub.

Txais Tos Dav Dav

Tshaj 90% ntawm cov lag luam lees txais cov ntawv pov thawj xws li CFOT thiab CFOS, uas muaj cov kev xeem sau ntawv thiab kev xeem xyaum. Tag nrho cov no suav nrog cov kws tshaj lij uas tau txais daim ntawv pov thawj raws li qhov kev pab cuam muab cov txiaj ntsig txhim khu kev qha thiab sib xws tshaj plaws.

Kev Txhim Kho Koj Txoj Kev Nqis Peev Fiber Yav Tom Ntej

Kev ua kom koj cov peev nyiaj fiber ruaj khov rau yav tom ntej yog qhov tseem ceeb txog kev ntseeg siab thiab kev ua tau zoo mus sij hawm ntev. Los ntawm kev xav txog kev nthuav dav yav tom ntej thiab cov kev xav tau thaum lub sijhawm npaj, koj tuaj yeem zam kev rov nqis peev uas cuam tshuam thiab kim heev nrog rau lub sijhawm poob kom ntseeg tau tias kev sib txuas lus ceev ceev tseem ceeb txuas ntxiv mus.

Yog tias koj muaj ib txoj kev npaj ua tiav lawm, koj tuaj yeem xaiv cov cables uas muaj peev xwm ua tau raws li kev nce qib ntawm thev naus laus zis yav tom ntej thiab ua rau cov kev xav tau bandwidth nce ntxiv.

Kev Muaj Peev Xwm Loj Hlob Tau Rau Yav Tom Ntej

Thaum xaiv cov cables fiber optic, qhov kev nthuav dav yuav tsum yog koj qhov tseem ceeb tshaj plaws. Cov tes hauj lwm ceev ceev nrog rau qhov kev thov cov ntaub ntawv nce ntxiv ua rau cov cables uas tuaj yeem pab txhawb kev loj hlob thaum tshem tawm qhov xav tau kev hloov pauv tas mus li.

Piv txwv li, siv wavelength multiplexing es tsis txhob ntxiv cov fibers tso cai rau kev sib kis ntau dua xws li 40G lossis 100G hla cov cables uas twb muaj lawm, txuag ob lub sijhawm thiab tus nqi. Lwm txoj hauv kev, xws li OM5 wideband multimode fiber (WBMMF), ua rau qhov ntsuas ntau ntxiv.

Lawv ua kom muaj cov thev naus laus zis zoo li SWDM4 thiab sib xws nrog OM3 thiab OM4 duplex MMF uas twb muaj lawm. Xaiv cov cables uas siv qhov chaw tsawg dua nrog cov connectors me dua, xws li Corning/Senko CS connector. Qhov kev txiav txim siab tshwj xeeb no yuav ua rau yav tom ntej muaj qhov chaw rau cov tes hauj lwm tuab uas khiav ntawm 200G lossis 400G.

Kev Txhim Kho Txoj Kev thiab Kev Sib Xws

Kev tiv thaiv yav tom ntej suav nrog kev tawm chaw rau kev txhim kho txoj hauv kev thiab xyuas kom meej tias muaj kev sib koom tes. Singlemode thiab multimode fibers muaj lub hom phiaj sib txawv. Lub hauv paus txoj kab uas hla thiab cov ntsiab lus cladding tseem ceeb dua rau lawv cov kev ua tau zoo.

Kev xaiv hom zoo ua kom muaj kev sib raug zoo thiab kev sib txuas nrog cov khoom siv tam sim no thiab yav tom ntej. Kev xaus kom raug tsis yog tsuas yog kev xyaum ua kom zoo xwb, tab sis nws yog qhov tseem ceeb rau kev ua tiav ntawm kev pab cuam.

Qhov tseeb, kev xaus tsis zoo yog lub luag haujlwm rau yuav luag 40% ntawm kev teeb tsa, ua rau lub sijhawm tsis ua haujlwm ntawm lub network kim heev thiab rov ua haujlwm dua.

Cov Txuj Ci Tshiab thiab Cov Qauv Tshiab

Nyob ua ntej ntawm txhua yam txhais tau tias yuav tsum xav txog cov thev naus laus zis tshiab. Kev nkag mus rau cov peev xwm tsim khoom siab heev, xws li 13 txoj kab tsim khoom uas muab cov khoom lag luam zoo tshaj plaws hauv kev lag luam, lav qhov zoo thiab muaj rau cov tes hauj lwm uas nthuav dav sai.

Kev paub txog cov qauv xws li WBMMF thiab kev hloov pauv ntawm cov qauv txuas yuav pab txhawb koj txoj kev nqis peev yav tom ntej.
