Nrog rau diversified txoj kev loj hlob ntawmOptical fiber ntau transceiver khoom, lawv txoj kev faib tawm kuj txawv, tab sis muaj qee qhov kev sib raug zoo ntawm ntau hom kev faib tawm.
Los ntawm tus nqi
Nws tuaj yeem muab faib ua 10M, 100M, 1000M, 10G optical fiber transceivers, 10/100m adaptive, 10/100/1000m adaptive optical fiber transceivers.
Feem ntau ntawm ib leeg 10M, 100M thiab 1000M transceiver cov khoom ua haujlwm nyob rau hauv lub cev txheej, qhov twg cov khoom transceiver ua haujlwm me ntsis-los-ntsis rau xa cov ntaub ntawv.
Hom kev xa tawm no muaj qhov zoo ntawm kev xa mus ceev ceev thiab qeeb qeeb, thiab tsim nyog rau tus nqi txuas txuas. Thaum 10/100M thiab 10/100/1000M optical fiber transceivers ua haujlwm ntawm cov ntaub ntawv txuas txheej thiab siv lub khw muag khoom-thiab-mus rau tom ntej mechanism. Ua li no, txhua pob ntawv tau txais los ntawm kev xa mus yuav tsum nyeem nws qhov chaw nyob MAC, qhov chaw nyob MAC thiab cov ntaub ntawv them nqi, thiab cov pob ntawv yuav raug xa mus tom qab CRC cyclic redundancy check tiav.
Txoj kev khaws cia-thiab-rau-txoj kev pab cuam tuaj yeem tiv thaiv qee qhov kev sib kis tsis zoo hauv lub network, nqa cov peev txheej tseem ceeb hauv lub network, tab sis kuj yog ib txoj hauv kev zoo los tiv thaiv cov pob ntawv poob vim kev sib txuas hauv network, thaum cov ntaub ntawv txuas saturation tuaj yeem khaws thiab xa mus yuav tsis raug. muaj peev xwm xa cov ntaub ntawv nyob rau hauv lub cache nyob rau hauv lub transceiver (ua ntej, tos kom xa mus rau lub network idle dua. Qhov no tsis tsuas yog txo qhov muaj peev xwm ntawm cov ntaub ntawv tsis sib haum xeeb tab sis kuj ua kom muaj kev ntseeg siab ntawm cov ntaub ntawv xa mus. Yog li ntawd, 10/100M thiab 10/100/1000M optical. fiber ntau transceivers yog tsim rau kev ua haujlwm ntawm qhov txuas nrog tus nqi sib txawv.
Raws li txoj kev ua haujlwm los faib
Raws li tau hais los saum no, nws tuaj yeem muab faib ua optical fiber transceivers ua haujlwm ntawm lub cev txheej thiab optical fiber transceivers ua haujlwm ntawm cov ntaub ntawv txuas txheej.
Nws tuaj yeem muab faib ua hom duab (kev ywj pheej) optical fiber transceiver thiab khib hom optical fiber transceiver. Desktop hom optical fiber transceiver yog tsim rau tib neeg siv (thiab built-in fais fab transceiver thiab sab nraud fais fab transceiver), xws li kom tau raws li kev sib txuas sab sauv ntawm ib qho kev hloov hauv txoj kev hauv tsev. Racking fiber ntau transceiver yog tsim rau ntau tus neeg siv convergence. Piv txwv li, chav tsev computer hauv nruab nrab ntawm cov zej zog yuav tsum ua tau raws li kev sib txuas sab saud ntawm txhua qhov hloov pauv hauv zej zog. Kev siv cov khib nyiab yog ib qho yooj yim kom paub txog kev tswj hwm kev sib koom ua ke thiab kev sib koom ua ke ntawm tag nrho cov khoom siv fiber ntau transceivers.
Faib los ntawm optical fiber
Nws tuaj yeem muab faib ua multimode fiber ntau transceiver thiab ib hom fiber ntau transceiver. Raws li kev siv fiber ntau optical, cov transceivers tuaj yeem xa mus rau qhov sib txawv. Multimode transceivers feem ntau kis ntawm 2 thiab 5 kilometers, thaum ib hom transceivers tuaj yeem npog thaj tsam ntawm 20 txog 120 mais.
Nws yuav tsum tau muab sau tseg hais tias lub transmitting hwj chim, tau txais rhiab heev thiab wavelength ntawm optical fiber transceivers lawv tus kheej yuav txawv vim qhov sib txawv kis deb. 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 nyob nruab nrab ntawm -3 ~ 0dB, qhov tau txais rhiab heev yog tsawg dua -36dB, thiab lub wavelength ntawm 1550nm yog siv.
Faib los ntawm tus naj npawb ntawm optical fibers
Nws tuaj yeem muab faib ua ib qho fiber ntau transceiver thiab ob npaugfiber ntau transceiver. 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. Xws li cov khoom siv thev naus laus zis ntawm wavelength division multiplexing, uas feem ntau siv lub wavelengths ntawm 1310nm thiab 1550nm rau kev sib kis luv luv (0-60km) thiab 1490nm thiab 1550nm rau kev sib kis ntev (60km-120km). Nrog rau kev siv ntau dua ntawm ib qho fiber ntau optic transceivers, cov khoom tau dhau los ua neeg paub tab thiab ruaj khov.
Faib los ntawm kev siv fais fab
Nws tuaj yeem muab faib ua built-in fais fab mov thiab sab nraud fais fab mov. Cov khoom siv hluav taws xob hloov hluav taws xob yog cov khoom siv hluav taws xob hauv chav kawm, thaum cov khoom siv hluav taws xob sab nraud feem ntau siv hauv cov khoom siv pej xeem. Qhov zoo ntawm cov qub yog tias nws tuaj yeem txhawb nqa ultra-wide fais fab mov voltage, zoo dua kev paub txog kev tswj hluav taws xob, lim thiab cov khoom siv hluav taws xob tiv thaiv, thiab txo qis cov ntsiab lus cuam tshuam sab nraud los ntawm kev sib cuag nrog cov neeg kho tshuab. Qhov zoo ntawm qhov tom kawg yog qhov me me ntawm cov khoom siv, yooj yim rau kev siv 14- qhov chaw khib nruab nrab ntawm kev tswj hwm thiab tus nqi qis.
Tsis tas li ntawd, los ntawm hom fais fab mov voltage ntawm cov khoom siv, muaj AC 220V, 110V, 60V; DC -48V, 24V, thiab lwm yam.
Nias network tswj kom faib
Nws tuaj yeem muab faib ua lub network tube hom fiber ntau optic transceiver thiab non-net tube homfiber ntau optic transceiver.Nrog rau kev txhim kho lub 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 cov khoom lag luam, xws li cov keyboards thiab routers, tseem tab tom txhim kho hauv cov kev taw qhia no maj mam. 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 hwm ntawm qhov chaw ua haujlwm kawg yog cov khoom khib nyiab, uas feem ntau siv cov qauv kev tswj hwm tus qhev, uas yog, tus tswv network tswj module tuaj yeem ua haujlwm N qhev network tswj modules, thiab txhua tus qhev network tswj. module tsis tu ncua soj ntsuam cov xwm txheej cov ntaub ntawv ntawm tag nrho cov fiber-optic transceivers ntawm nws sub-rack thiab xa mus rau tus tswv network tswj module. Ntawm qhov tod tes, qhov tseem ceeb ntawm kev tswj hwm kev lag luam 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.
