Fiber Ntau Optical Technology Cov Lus Qhia thiab Cov Lus Qhia
Nws Ua Haujlwm Li Cas?
Peb tuaj yeem xav nws raws li cov ntaub ntawv hais txog tus lej yog "cim", lossis tso rau ntawm cov hluav taws xob sib kis rau cov kis. Cov ntaub ntawv mus raws cov iav fiber ntau ntawm qhov ceev ntawm lub teeb (186,000 mais / thib ob). Thaum nws mus txog nws qhov chaw kawg, ib tus lej txiav txim siab hloov cov ntaub ntawv lub teeb rau hauv daim duab, suab.
Fiber Optic Cables siv cov khoom ntawm cov khoom siv hauv qab no:
Cov tub ntxhais - Pob tshab yas lossis iav uas hla lub teeb
Clading - Iav npog ib puag ncig tus tub ntxhais uas ua raws li lub tsom iav kom pom qhov pom rov qab rau hauv tub ntxhais. Qhov no hu ua kev xav sab hauv tag nrho
Tawb tsis haum - Tsho tiv thaiv thiab tiv thaiv fiber ntau
Aramid cov xov paj muaj zog cov tswv cuab - Ua kom muaj kev ncaj ncees ntawm cov ntaub ntawv xa mus los ntawm cov khoom siv kho qhov muag hauv kab hluav taws xob.
Kev tiv thaiv cov tsho sab nrauv - Ectruded PVC yog tus raug
Fiber ntau Cable hom
Muaj ob qhov yooj yim ntawm hom cable. Simplex thiab Duplex . Ob txoj hlua cable tuaj rau hauv: Singlemode thiab Multimode. Singlemode yog rau ntev khiav cable khiav thiab Multimode yog rau luv dua cable khiav.
Cov Khoom Siv Fiber Optic thiab Cov Khoom Siv Kuaj
Nrog txhua qhov fiber nruab, yuav tsum muaj cov cuab yeej tshwj xeeb thiab cov khoom siv coj los ua txoj haujlwm tiav. FOCC pom zoo cov cuab yeej Fiber Optic hauv qab no thiab khoom siv los ntawm Fusion Splicers kom kuaj cov khoom siv.
Tus Npav Fiber Tsim
Muaj ob qho yooj yim ntawm hom qauv siv cable. Lawv yog: Loose Tube (feem ntau siv rau "OSP" sab nraum nruab kev cog ntoo) thiab Tight Buffered (feem ntau siv rau sab hauv nruab).
Tube xoob fiber ntau cable muaj: (qhia raws li daim duab xis)
Ntau txheej 250µm lo cov xim
Ib los yog ntau txoj hlua xoob uas tuav cov xaim ntawd
Gel-sau los thaiv cov dej noo thiab tiv thaiv kev txav ntawm cov fibers
Kev txhawb nqa lub zog nruab nrab
Aramid cov xov xov muaj zog ua haujlwm
Tsho laus tsho
Tight Buffered fiber cable muaj (qhia raws li sab laug):
900µm nruj tsis nyob ib ncig ntawm 250µm fiber
Hab txhawb zog ua tswv cuab
Aramid cov xov xov muaj zog ua haujlwm
Tsho laus tsho
Ib Qhov Fiber Optic Splitter sib txuas cov teeb liab thiab cov sib cais tawm ntawm ib qho los yog ntau cov khoom tawm. FOCC splitters yog cov tshuaj tiv thaiv hluav taws xob-sib nqus (EMI), tsis muaj hluav taws xob, thiab tsis txhob ntxiv cov suab nrov rau cov qauv tsim. FOCC splitters tuaj yeem tsim tau nyob rau hauv kev cai fiber ntau qhov ntev thiab nrog ib yam ntawm cov khoom siv sib txuas.
FOCC yog cov kws tshaj lij cov khoom lag luam nyob hauv cov fiber ntau qhov muag plua plav, nws muab txhua yam ntawm cov khoom lag luam fiber ntau saum toj saud hauv tsab xov xwm, thiab muaj xov zoo hais tias nws ua 30% luv nqi ua ntej tus nqi, yog tias muaj qee qhov xav tau , FOCC yog qhov kev xaiv zoo heev.
