Optical fiber yog ib qho tseem ceeb ntawm lub hnub nyoog network, tab sis koj puas to taub tiag tiag fiber ntau?Txoj kev sib txuas ntawm fiber ntau yog dab tsi?Dab tsi yog qhov txawv ntawm optical cable thiab optical fiber ntau?Puas yog nws ua tau rau fiber ntau los hloov cov tooj liab cables los ntawm sab nraud
Txoj kev sib txuas ntawm fiber ntau yog dab tsi?
1. Active kev twb kev txuas:
Kev sib txuas nquag yog ib txoj hauv kev sib txuas ntawm qhov chaw mus rau qhov chaw lossis qhov chaw mus rau fiber ntau optic cable siv ntau yam khoom siv fiber ntau txuas (plugs thiab sockets).Txoj kev no yog yoog raws, yooj yim, yooj yim, thiab txhim khu kev qha, thiab feem ntau siv hauv computer network thaiv hauv cov tsev.Nws ib txwm attenuation yog 1dB / connector.
2. Kev sib txuas thaum muaj xwm ceev (tseem hu ua) txias melting:
Kev sib txuas xwm ceev feem ntau yog siv cov cuab yeej siv tshuab thiab tshuaj los kho thiab khi ob lub fibers optical ua ke.Cov yam ntxwv tseem ceeb ntawm txoj kev no yog qhov kev sib txuas yog ceev thiab txhim khu kev qha, thiab qhov kev sib txuas ntawm qhov raug yog 0.1-0.3dB / taw tes.
Lawv tuaj yeem txuas rau hauv cov khoom sib txuas thiab ntsaws rau hauv fiber ntau qhov (sockets).Lub connector siv 10% mus rau 20% ntawm lub teeb, tab sis nws ua rau nws yooj yim rau reconfigure lub system.Txawm li cas los xij, qhov taw qhia kev sib txuas yuav tsis ruaj khov rau lub sijhawm ntev thiab qhov attenuation yuav nce siab heev, yog li nws tsuas yog siv tau thaum muaj xwm txheej ceev. ib lub sij hawm luv luv.
Nws tuaj yeem koom nrog mechanically.Ua li no, tso ib kawg ntawm ob ua tib zoo txiav fibers rau hauv ib lub raj thiab clamp lawv ua ke.Cov fiber ntau tuaj yeem hloov kho los ntawm kev sib tshuam kom ua kom lub teeb pom kev zoo.Kev sib koom ua ke yuav tsum tau siv li 5 feeb rau cov neeg ua haujlwm kawm tiav, thiab qhov poob ntawm lub teeb yog li 10%.
3. Kev sib txuas ntawm fiber ntau (tseem hu ua kub yaj):
Hom kev sib txuas no siv hluav taws xob tawm mus rau fuse thiab txuas cov ntsiab lus txuas ntawm fiber ntau.Feem ntau yog siv rau kev sib txuas mus ntev, kev sib txuas mus tas li lossis semi-permanent.Nws lub ntsiab feature yog qhov kev sib txuas attenuation yog qhov qis tshaj ntawm txhua txoj kev sib txuas, nrog tus nqi raug ntawm 0.01-0.03dB / point.
Txawm li cas los xij, thaum sib txuas, cov cuab yeej tshwj xeeb (lub tshuab vuam) thiab cov kev ua haujlwm yuav tsum tau ua, thiab qhov kev sib txuas ntawm qhov taw tes yuav tsum tau tiv thaiv los ntawm lub thawv tshwj xeeb.Ob lub fibers tuaj yeem fused ua ke los tsim kev sib txuas.
Cov fiber ntau tsim los ntawm txoj kev fusion yog yuav luag tib yam li ib qho fiber ntau, tab sis muaj me ntsis attenuation.Rau tag nrho peb txoj kev sib txuas, muaj kev xav ntawm qhov sib txuas, thiab lub zog uas muaj zog cuam tshuam nrog lub teeb liab.
Nws yog ib qho tsim nyog kom nkag siab txog qhov poob ntawm cov fiber ntau optical kom zoo dua siv cov fiber ntau optical.Lub luag haujlwm tseem ceeb ntawm Fluke's CertiFiber Pro Optical Loss Tester fiber ntau yog kuaj qhov poob thiab tsis ua haujlwm ntawm fiber ntau.
Fluke's CertiFiber Pro Optical Loss Tester fiber ntau tuaj yeem:
1. Peb-thib ob tsis siv neeg kuaj - (plaub zaug sai dua li cov neeg kuaj ib txwm muaj) suav nrog: kev ntsuas qhov muag pom ntawm ob lub fibers ntawm ob lub wavelengths, ntsuas qhov deb thiab kev ntsuas qhov muag tsis pom
2. Muab kev ntsuas tsis siv neeg hla / tsis ua haujlwm raws li cov qauv kev lag luam lossis cov kev cai xeem txwv
3. Txheeb xyuas cov txheej txheem xeem tsis raug uas ua rau "tsis zoo" cov txiaj ntsig
4.Onboard (USB) lub koob yees duab tshuaj xyuas cov ntaub ntawv fiber ntau endface duab
5. Cov khoom siv hluav taws xob hloov pauv hloov pauv tau muaj rau txhua hom kev sib txuas (SC, ST, LC, thiab FC) rau qhov tseeb ib leeg jumper siv txoj kev
6.Built-in video txhaum locator rau kev kuaj mob yooj yim thiab pom polarity
7. Dual wavelength ntsuas muaj peev xwm ntawm ib qho fiber ntau tso cai rau tus neeg ntsuas ntsuas siv rau hauv cov ntawv thov uas yuav tsum muaj ib qho txuas fiber ntau.
Tsis muaj cov cuab yeej siv ntxiv lossis cov txheej txheem yuav tsum ua raws li TIA-526-14-B thiab IEC 61280-4-1 ring flux cov cai.
Dab tsi yog qhov txawv ntawm optical cable thiab optical fiber
Cov kab hluav taws xob kho qhov muag yog tsim los ntawm qee tus lej ntawm cov khoom siv kho qhov muag.Cov tub ntxhais sab nraud yog npog nrog cov ntaub qhwv thiab cov txheej txheem tiv thaiv kev sib txuas lus thiab cov ntaub ntawv muaj peev xwm loj-ntev mus ntev.
Optical fiber yog cov cuab yeej sib kis, ib yam li cov hlau nyias nyias.Cov fiber ntau nyias nyias yuav muab ntim rau hauv lub tes tsho yas rau kev xa xov mus ntev.Yog li ntawd, lub fiber optic cable muaj optical fiber.
Thaum kawg, cia peb tham txog ib kab.Ib tug cable yog tsim los ntawm ib tug conductive hlau core, ib tug rwb thaiv tsev txheej, thiab ib tug sealing txheej tiv thaiv.Nws yog ua los ntawm cov khoom siv hlau (feem ntau yog tooj liab, txhuas) ua tus neeg xyuas pib, thiab siv los xa cov ntaub ntawv hluav taws xob lossis cov ntaub ntawv.Cov hlau yog twisted.Cables feem ntau yog siv rau hauv kev thauj mus los hubs, substations, thiab lwm yam. Qhov tseeb, cov xov hlau thiab cables tsis muaj kev txwv nruj.Feem ntau, peb hu xov tooj nrog me me diameters thiab tsawg lub hlwb raws li nyob ntawm tej, thiab cables nrog loj diameters thiab ntau lub hlwb.
Puas yog nws ua tau rau cov fibers kho qhov muag kom hloov tau cov tooj liab los ntawm sab nraud?
Nyob rau hauv feem ntau cov chaw zov me nyuam, fiber ntau tau ua lag luam vim muaj kev xav tau siab bandwidth.Tsis tas li ntawd, fiber ntau optic cables tsis raug cuam tshuam rau electromagnetic cuam tshuam, thiab lawv cov kev xav tau ntawm ib puag ncig yuav tsis nyuaj li tooj liab cables.Yog li ntawd, lub optical fiber yog yooj yim rau nruab.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias txawm hais tias tus nqi sib txawv ntawm optical fibers thiab tooj liab cables tau nqaim, tag nrho cov nqi ntawm optical cables yog siab dua tooj liab cables.Yog li ntawd, fiber ntau yog siv dav hauv ib puag ncig uas xav tau ntau dua bandwidth, xws li cov chaw zov me nyuam.
Ntawm qhov tod tes, tooj liab cables tsis tshua kim.Optical fiber yog ib hom tshwj xeeb ntawm iav fiber ntau uas tsis yooj yim dua li tooj liab cables.Yog li ntawd, tus nqi tu txhua hnub ntawm tooj liab cable yog qis dua li ntawm fiber ntau optical.Nws kuj tseem muab rov qab sib raug zoo nrog cov laus 10 / 100Mbps legacy Ethernet li.
Yog li ntawd, tooj liab cables tseem siv nyob rau hauv lub suab kis tau tus mob thiab nyob rau hauv tsev siv network.Tsis tas li ntawd, kab rov tav kab rov tav, Lub Hwj Chim dhau Ethernet (POE), lossis Internet of Things daim ntawv thov yog tsav kev siv tooj liab cables.Yog li ntawd, fiber ntau optic cables yuav tsis tas hloov tooj liab cables.
Txog kev paub me me ntawm fiber ntau optical, kuv yuav thawb ntawm no rau txhua tus neeg niaj hnub no.Fiber optic cables thiab tooj liab cables tuaj yeem muab kev pabcuam kev sib txuas hauv Is Taws Nem rau cov tsev thiab kev lag luam.Qhov tseeb, cov kev daws teeb meem fiber ntau thiab tooj liab yuav sib koom ua ke hauv lub neej yav tom ntej, thiab txhua qhov kev daws teeb meem yuav siv qhov twg nws ua rau muaj kev nkag siab zoo tshaj plaws.
