Nrog rau kev nthuav dav ntau lawm ntawm cov khoom siv fiber ntau transceiver, lawv cov txheej txheem kev faib tawm kuj yog qhov sib txawv, tab sis muaj qee qhov cuam tshuam ntawm ntau hom kev faib tawm.
Los ntawm cov nqi
Nws tuaj yeem muab faib ua 10M, 100M, 1000M, 10G optical fiber transceivers, 10 / 100m adaptive, 10/100 / 1000m coj mus kho qhov muag fiber ntau kis.
Feem ntau ntawm tib 10M, 100M thiab 1000M transceiver khoom ua haujlwm nyob rau hauv lub cev txheej, qhov twg transceiver cov khoom ua haujlwm me ntsis-rau-me ntsis mus rau xa cov ntaub ntawv.
Qhov kev xa mus ntxiv no muaj qhov zoo ntawm kev xa ceev nrawm dua thiab qeeb qeeb, thiab tsim nyog rau kev sib hloov pauv. Thaum 10 / 100M thiab 10/100 / 1000M optical fiber transceivers ua haujlwm ntawm cov ntaub ntawv txuas txheej thiab siv cov khoom muag-thiab-dhau. Hauv txoj kev no, txhua pob ntawv tau txais los ntawm kev xa mus ntxiv yuav tsum nyeem nws qhov chaw MAC chaw nyob, chaw nyob MAC chaw nyob thiab cov ntaub ntawv them nqi, thiab pob ntawv yuav xa tawm tom qab CRC cyclic rov ua kom tiav.
Khaws thiab-rau cov txiaj ntsig txoj hauv kev tuaj yeem tiv thaiv qee qhov tsis ncaj ncees xov xwm xa mus rau hauv lub network, nqa cov khoom muaj txiaj ntsig ntawm lub network, tab sis kuj yog txoj hauv kev zoo los tiv thaiv pob ntawv poob vim lub network tsis sib haum, thaum cov ntaub ntawv txuas saturation tuaj yeem khaws thiab tom ntej yuav tsis yog tuaj yeem xa cov ntaub ntawv hauv lub cache hauv transceiver (ua ntej, tos txog kev xa mus tom lub network tsis ua ntxiv mus. Qhov no tsis tsuas yog txo txoj kev muaj peev xwm ntawm cov ntaub ntawv tsis sib haum tab sis kuj ua kom ntseeg tau tias muaj kev ntseeg tau ntawm cov ntaub ntawv xa mus.) Yog li, 10 / 100M thiab 10/100 / 1000M optical. fiber transceivers yog qhov tsim nyog rau kev ua haujlwm ntawm lub txuas nrog tus nqi sib txawv.
Raws li txoj kev ntawm kev ua haujlwm faib
Raws li tau hais los saum toj no, nws tuaj yeem muab faib ua cov hluav taws xob fiber ntau cov ua haujlwm ntawm cov txheej txheem lub cev thiab cov kis las fiber ntau ua haujlwm ntawm cov ntaub ntawv txuas txheej.
Muab faib los ntawm kev teeb tsa
Nws tuaj yeem muab faib ua desktop hom (ywj siab) optical fiber transceiver thiab rack type optical fiber transceiver. Desktop hom optical fiber transceiver yog qhov tsim nyog rau ib tus neeg siv (thiab cov ua lub zog txuas ntawm lub zog thiab lub zog sab nraud), xws li kom tau raws li cov kev sib txuas sab saud ntawm ib tus hloov mus rau hauv txoj kev hauv tsev. Racking fiber transceiver yog qhov tsim nyog rau ntau tus neeg siv sib sau ua ke. Piv txwv li, chav siv computer hauv nruab nrab ntawm cov neeg zej zog yuav tsum tau muaj kev sib txuas sab saud ntawm txhua tus keyboards hauv zej zog. Kev siv ntawm kev sib tsoo yooj yim kom paub qhov kev tswj hwm kev sib koom ua ke thiab kev koom ua ke sib txuas ua ke fais fab ntawm txhua tus qauv hloov fiber ntau.
Faib los ntawm fiber ntau kho qhov muag
Nws tuaj yeem faib ua multimode fiber transceiver thiab ib hom fiber ntau transceiver. Nyob ntawm cov siv hluav taws xob fiber ntau, cov kab txuas tuaj yeem sib kis sib txawv. Multimode transceivers feem ntau sib kis ntawm 2 mus rau 5 kis lus mev, thaum tib hom transceivers tuaj yeem npog thaj tsam li ntawm 20 txog 120 kis lus mev.
Nws yuav tsum tau taw qhia tias lub zog hloov mus, txais kev nkag siab zoo thiab nthwv dej ntawm cov hluav taws xob fiber transceivers lawv tus kheej yuav sib txawv vim qhov sib txawv ntawm cov kis sib txawv. Piv txwv, txoj kev sib kis ntawm 5km optical fiber transceiver feem ntau ntawm -20 ~ -14dB, qhov tau txais qhov nkag siab yog -30dB, thiab qhov ntev ntawm 1310nm siv. Txawm li cas los xij, cov kis sib kis ntawm 120km optical fiber transceivers feem ntau nyob nruab nrab ntawm -3 ~ 0dB, qhov tau txais cov pa tsis txaus siab yog tsawg dua -36dB, thiab qhov ntev ntawm 1550nm siv.
Faib los ntawm cov xov tooj ntawm cov kho qhov muag
Nws muaj peev xwm raug faib ua cov fiber ntau transceiver thiab ob chav fiber ntau transceiver. Raws li lub npe pom, ib qho khoom siv fiber ntau muaj peev xwm txuag tau ib nrab ntawm cov kho qhov muag, uas yog, cov ntaub ntawv tuaj yeem tau txais thiab xa tawm ntawm cov kho qhov muag fiber ntau, nws tau txais txiaj ntsig zoo hauv cov chaw uas muaj cov khoom siv fiber tsawg. Cov khoom lag luam txais yuav lub thev naus laus zis ntawm wavelength faib multiplexing, uas feem ntau siv nthwv dej ntawm 1310nm thiab 1550nm rau kev sib kis luv (0-60km) thiab 1490nm thiab 1550nm rau kev sib kis ntev (60km-120km). Nrog rau kev siv dav dav ntawm cov fiber ntau kis ntawm cov khoom, cov khoom tau dhau los ua neeg laus thiab ruaj khov.
Faib los ntawm cov khoom siv fais fab
Nws tuaj yeem faib ua cov hwj huam txuas nrog sab hauv thiab sab nraud fais fab mov. Lub tshuab hluav taws xob hauv lub tshuab hloov hluav taws xob yog lub tuam txhab xa khoom siv hluav taws xob, thaum sab nraud lub zog hluav taws xob hloov hluav taws xob feem ntau siv hauv cov khoom siv hauv zej zog. Qhov zoo dua ntawm cov qub yog tias nws tuaj yeem txhawb ultra-dav fais fab fais fab voltage, paub zoo dua voltage txoj cai, kev lim dej thiab cov cuab yeej siv zog tiv thaiv, thiab txo cov kev txhaum sab nraud los ntawm kev sib chwv. Qhov zoo ntawm tom kawg yog qhov loj me me ntawm cov cuab yeej siv, yooj yim siv 14-txoj kab khib nruab nrab cov kev tswj hwm thiab tus nqi qis.
Ib qho ntxiv, los ntawm hom fais fab fais fab voltage ntawm cov khoom siv, muaj AC 220V, 110V, 60V; DC -48V, 24V, thiab lwm yam.
Xovxwm kev tswj hwm network kom faib
Nws tuaj yeem muab faib ua network raj hom fiber ntau optic transceiver thiab non - network tube hom fiber ntau kis. Nrog txoj kev txhim kho network kom ua haujlwm tau zoo thiab tswj tau, feem ntau cov neeg ua haujlwm cia siab tias txhua yam khoom siv hauv lawv lub network tuaj yeem tswj tau nyob deb. Fiber optic transceiver khoom, zoo li hloov thiab routers, kuj tseem tab tom txhim kho hauv cov kev taw qhia no maj mam. Cov hluav taws xob fiber ntau xa mus nrog kev tswj hwm network kuj tseem tuaj yeem faib rau kev tswj hwm hauv nroog thiab cov kev tswj hwm network. Cov khoom siv hluav taws xob fiber ntau uas tuaj yeem tswj tau nyob rau ntawm lub chaw lis haujlwm kawg yog feem ntau ntaus cov khoom lag luam, uas feem ntau txais cov qauv tswj tus tswv-qhev, uas yog, tus tswv network tswj module tuaj yeem ua N qhev network tswj modules, thiab txhua tus qhev network tswj hwm module tsis tu ncua cov ntaub ntawv xwm txheej ntawm txhua qhov fiber ntau ntawm cov xa hluav taws xob ntawm nws qhov sub-rack thiab muab xa mus rau tus kws xaib tswj network. Ntawm ib sab tes, lub ntsiab tswj hwm lub network yuav tsum tshawb xyuas cov ntaub ntawv kev tswj hwm lub network ntawm nws tus kheej kev sib tw, thiab ntawm qhov tod tes, nws yuav tsum sau tag nrho cov ntaub ntawv los ntawm sub-rack, thiab tom qab ntawd sau cov ntsiab lus thiab xa mus rau lub network tswj neeg rau zaub mov.
