Txhawm rau kom ntseeg tau tias muaj kev sib raug zoo nrog cov khoom siv hauv network xws li daim npav network, Repeaters, hubs thiab keyboards los ntawm lwm lub tuam txhab,fiber ntau optic transceiversyuav tsum nruj me ntsis ua raws li Ethernet cov qauv xws li 10Base-T, 100Base-TX, 100Base-FX, IEEE 802.3 thiab IEEE 802.3U. Ntxiv rau, lawv yuav tsum ua raws li FCC Part15 hais txog EMC tiv thaiv hluav taws xob hluav taws xob. Niaj hnub no, raws li cov neeg ua haujlwm hauv tsev tau siv zog ua haujlwm hauv tsev, tsev kawm ntawv network thiab kev lag luam network, kev siv cov khoom siv fiber ntau optical transceiver kuj nce ntxiv, txhawm rau ua kom tau raws li cov kev xav tau ntawm kev siv network tsim.
Qhov xwm ntawm kev faib tawm
Ib hom fiber ntau optic transceiver: kis tau tus mob 20 km txog 120 km
Multimode fiber optic transceiver: kis tau tus mob ntau 2km txog 5km
Piv txwv li, lub zog xa hluav taws xob ntawm 5km optical fiber ntau transceiver feem ntau yog nruab nrab ntawm -20 ~ -14dB, qhov tau txais rhiab heev yog -30dB, thiab lub wavelength ntawm 1310nm yog siv. Txawm li cas los xij, lub zog xa hluav taws xob ntawm 120km optical fiber ntau transceivers feem ntau yog nruab nrab ntawm -5 ~ 0dB, qhov tau txais rhiab heev yog -38dB, thiab lub wavelength ntawm 1550nm yog siv.
Kev faib tawm
Ib leeg fiber optic transceiver: txais thiab xa cov ntaub ntawv ntawm ib qho fiber ntau
Dual fiber optic transceiver: tau txais thiab xa cov ntaub ntawv hla ib khub ntawm optical fibers
Raws li lub npe qhia, ib qho khoom siv fiber ntau tuaj yeem txuag tau ib nrab ntawm cov khoom siv kho qhov muag, uas yog, cov ntaub ntawv tuaj yeem tau txais thiab xa mus rau ib qho khoom siv fiber ntau, uas yog qhov tseem ceeb heev hauv cov chaw uas muaj fiber ntau tsawg. Cov khoom lag luam no siv cov thev naus laus zis ntawm wavelength division multiplexing, uas feem ntau siv lub wavelength ntawm 1310nm thiab 1550nm. Txawm li cas los xij, vim tias tsis muaj cov txheej txheem thoob ntiaj teb sib koom ua ke rau cov khoom lag luam fiber ntau transceiver, cov khoom lag luam los ntawm cov tuam txhab sib txawv yuav tsis sib haum xeeb thaum sib koom ua ke. Tsis tas li ntawd, vim yog siv WDM, cov khoom siv fiber ntau transceiver feem ntau muaj cov yam ntxwv ntawm cov teeb liab siab attenuation.
Qib ntawm kev ua haujlwm / tus nqi
100M Ethernet fiber ntau optic transceiver: ua haujlwm ntawm lub cev txheej
10/100M adaptive Ethernet fiber ntau optic transceiver: ua haujlwm ntawm cov ntaub ntawv txuas txheej
Raws li qib ua haujlwm / tus nqi, nws tuaj yeem muab faib ua 10M, 100M optical fiber ntau transceivers, 10/100m adaptive optical fiber transceivers, 1000M optical fiber transceivers thiab 10/100/1000 adaptive optical fiber transceivers. Ntawm lawv, ib leeg 10M thiab 100M transceiver cov khoom ua haujlwm hauv lub cev txheej, thiab cov khoom siv transceiver ua haujlwm hauv txheej no xa cov ntaub ntawv me ntsis-los-ntsis. Hom kev xa tawm no muaj qhov zoo ntawm kev xa mus ceev ceev, siab permeability thiab qeeb qeeb, thiab tsim nyog rau kev sib txuas tus nqi ruaj khov. Nyob rau tib lub sijhawm, vim tias cov khoom siv no tsis muaj kev sib tham ntawm tus kheej ua ntej kev sib txuas lus, lawv ua tau zoo dua hauv kev sib raug zoo thiab kev ruaj ntseg.
Kev faib cov qauv
Desktop (sawv - ib leeg) fiber optic transceiver: sawv - ib leeg neeg siv khoom
Khib-hom (modular) fiber ntau optic transceiver: ntsia hauv 16- qhov chassis, siv lub zog nruab nrab
Kev tswj hwm hom Classification
Tsis yog - network - tube Ethernet fiber - optic transceiver: ntsaws - thiab - ua si, los ntawm kev kho vajtse dialing hloov teeb tsa hluav taws xob chaw nres nkoj ua haujlwm hom
Network-tswj Ethernet fiber optic transceivers: txhawb nqa-qib network tswj
Classification, tus thawj tswj network
Nws tuaj yeem muab faib ua non-network - tube fiber ntau - optic transceiver thiab network - tube fiber - optic transceiver. Cov neeg ua haujlwm feem ntau cia siab tias txhua yam khoom siv hauv lawv cov tes hauj lwm tuaj yeem tswj tau nyob deb, thiab fiber ntau optic transceivers tab tom txhim kho nyob rau hauv cov kev taw qhia no li keyboards thiab routers. Fiber-optic transceivers nrog kev tswj xyuas network kuj tseem tuaj yeem faib rau hauv kev tswj hwm hauv zos thiab kev tswj xyuas cov neeg siv khoom. Cov fiber ntau optic transceivers uas tuaj yeem tswj tau ntawm qhov kawg ntawm lub chaw lis haujlwm yog cov khoom siv khib nyiab, feem ntau ntawm cov qauv tswj kev tswj tus qhev. Ntawm ib sab, tus tswv network tswj module yuav tsum tau soj ntsuam cov ntaub ntawv tswj xyuas network ntawm nws tus kheej khib, thiab ntawm qhov tod tes, nws yuav tsum tau 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 server.
Kev tswj hwm tus neeg siv khoom tuaj yeem muab faib ua peb txoj hauv kev: thawj yog los khiav cov txheej txheem tshwj xeeb ntawm cov chaw lis haujlwm thiab cov neeg siv khoom. Cov txheej txheem yog lub luag haujlwm xa cov ntaub ntawv hauv xeev ntawm tus neeg siv khoom mus rau lub chaw lis haujlwm, uas yog ua tiav los ntawm CPU ntawm cov khoom siv hauv chaw lis haujlwm thiab xa mus rau lub network tswj server. Qhov thib ob yog tias fiber ntau optic transceiver ntawm lub zos kawg tuaj yeem ntes lub zog kho qhov muag ntawm qhov chaw nres nkoj kho qhov muag, yog li thaum muaj teeb meem ntawm txoj kev kho qhov muag, lub hwj chim kho qhov muag tuaj yeem siv los txiav txim seb nws puas yog qhov teeb meem ntawm qhov kho qhov muag. fiber ntau los yog qhov ua txhaum ntawm cov neeg siv khoom. Qhov thib peb yog txhawm rau txhim kho tus tswv CPU ntawm qhov kho qhov muag fiber ntau transceiver ntawm tus neeg siv khoom kawg, kom lub network tswj qhov system tuaj yeem saib xyuas kev ua haujlwm ntawm cov neeg siv khoom, thiab tseem paub txog kev teeb tsa chaw taws teeb thiab chaw taws teeb rov pib dua. Ntawm peb hom kev tswj xyuas cov neeg siv khoom network, thawj ob yog nruj me ntsis rau kev saib xyuas cov chaw taws teeb ntawm cov neeg siv khoom, thaum qhov thib peb yog kev tswj xyuas cov chaw taws teeb tiag tiag. Txawm li cas los xij, txij li txoj kev thib peb ntxiv CPU rau ntawm tus neeg siv khoom, uas ua rau nce tus nqi ntawm cov neeg siv khoom, thawj ob txoj hauv kev muaj qhov zoo ntawm cov nqi. Nws ntseeg tau tias kev tswj xyuas network ntawm optical fiber transceivers yuav ua tau ntau dua thiab muaj tswv yim thiab txawj ntse raws li cov neeg ua haujlwm xav tau ntau thiab ntau dua kev tswj cov khoom siv network.
Classification ntawm lub hwj chim mov
Built-in fais fab mov fiber ntau optic transceiver: Built-in switching fais fab mov yog cov cab kuj-qib fais fab mov; Sab nraud fais fab mov fiber optic transceiver: sab nraud transformer fais fab mov feem ntau yog siv rau hauv cov khoom siv pej xeem.
Kev faib ua haujlwm hom
Tag nrho duplex hais txog lub kaw lus uas qhov kev sib kis thiab txais cov ntaub ntawv tau muab faib ua ob kab sib txawv kom ob tog tuaj yeem xa thiab tau txais cov ntaub ntawv tib lub sijhawm. Nyob rau hauv tag nrho duplex, ib tug transmitter thiab ib tug receiver yog muab nyob rau hauv txhua kawg ntawm kev sib txuas lus system, yog li ntawd cov ntaub ntawv yuav raug tswj kom kis tau nyob rau hauv ob qho tib si cov lus qhia ib txhij. Tsis tas yuav hloov cov lus qhia hauv hom duplex tag nrho, yog li tsis muaj sijhawm ncua sijhawm cuam tshuam nrog kev hloov pauv haujlwm.
Ib nrab duplex yog cov kab sib kis uas tau txais thiab xa cov ntaub ntawv ntawm tib txoj kab sib kis. Txawm hais tias cov ntaub ntawv tuaj yeem xa mus rau ob qho tib si, ob tog tsis tuaj yeem xa thiab tau txais cov ntaub ntawv tib lub sijhawm. Nyob rau hauv ib nrab-duplex hom, lub transmitter thiab receiver ntawm txhua qhov kawg ntawm kev sib txuas lus system raug xa mus rau cov kab kev sib txuas lus los ntawm kev txais / xa mus, thiab cov kev taw qhia yog hloov. Yog li ntawd, yuav muaj sijhawm ncua sijhawm.
