100G CFP Daim Ntawv Thov
CFP, ib qho tau pom zoo 100G optical module, feem ntau yog thov hauv metro network thiab xa xov ntev (ib txwm dhau 10 km).
Yuav kom ua tiav lub cabling ntom thiab qhov ntev sib kis nrog CFP transceiver, lub architecture sib xyaw 16-channel dual fiber ntau DWDM Mux Demux los ntawm kev ntxiv MTP txoj hlua hluav taws xob thiab WDM SFP + OEO hloov mus hloov pauv cov SR ntw ntev mus rau DWDM wavelengths Cov. Yog li, DWDM kev sib koom tes ntev nrog 100G ntu CFP ntu tau tiav.
QSFP28 Daim Ntawv Thov
Tam sim no, QSFP28 pom tau tias yog cov qauv txuas tau tseem ceeb ntawm 100G optical modules. Muaj ntau QSFP28 cov khoom lag luam nyob rau hauv kev ua lag luam, suav nrog QSFP28 DAC / AOC cables thiab QSFP28 optical modules xws li 100G SR4 / LR4 / PSM4 / CWDM4 ntawm ntau hom. Cov khoom lag luam no feem ntau muab faib ua plaub daim ntawv thov hauv qab no raws li kev sib kis tau mus deb.
Tooj Liab DAC Siv Sab Hauv Nyiaj Raws Li 5 Qhov Nruab Nrab
QSFP28 DAC cov xaim hluav taws xob yog qhov zoo rau siv hauv kev sib txuas luv luv li ntawm 5 metres. Lawv tuaj yeem muab cov xov hluav taws xob sib dhos ua tiav tag nrho ntawm tus nqi them. Yog li no, yog tias koj 100G network tso rau hauv racks hauv 5 meters, koj tuaj yeem siv QSFP28 DAC cov cab hluav taws xob tsis yog 100G optical modules.
QSFP28 AOC / SR4 Transceiver rau 5-100 m
Muaj ob txoj hauv kev rau 100G multimode fiber cabling ntawm kev hloov ntawm 5 mus rau 100 meters. Ib qho yog siv QSFP28 AOC uas yog qhov zoo tshaj plaws rau 3-20 metres, thiab lwm qhov yog siv QSFP28 SR4 transceiver nrog 12-fiber MTP OM3 / OM4 cable, uas tuaj yeem txhawb qhov kis nrug ntawm mus txog 100 m.
QSFP28 PSM4 / CWDM4 / CLR4 Transceiver rau 100 m-2 km
Rau qhov nruab nrab kev sib txuas zoo li 100 meters rau 2 km, QSFP28 PSM4 thiab CWDM4 / CLR4 transceivers tuaj yeem muab cov nqi daws teeb meem. Lawv tuaj yeem pab txhawb nqa mus txog 500 meters dhau 12-fiber ntau MTP tib hom fiber ntau thiab 2 km dhau duplex LC ib hom fiber ntau.
QSFP28 LR4 / ER4 / ZR4 Transceiver rau Ntev Ntev
Rau kev ncua ntev 100GbE kev xa tawm, xws li kev sib txuas ntawm ob lub tsev (feem ntau txog 10 km), QSFP28-100G-LR4 nrog duplex LC ib hom fiber ntau yog qhov kev xaiv tau pom zoo los ntawm IEEE. Rau cov chaw nyob ntev (mus txog 40 km thiab 80 km), 100G QSFP28 ER4 thiab 100G QSFP28 ZR4 transceivers yog qhov zoo dua.
Daim Ntawv Thov: 100G CFP vs. QSFP28
Raws li rau 100G CFP vs. QSFP28, uas yuav siv rau koj qhov kev tsim kho network? Ua qhov tseeb, nws nyob ntawm ob qho tseem ceeb: qhov chaw nres nkoj yam ntawm koj cov khoom siv kho vajtse thiab cov ntawv thov kev pabcuam. CFP modules muaj ntau qhov loj dua li QSFP28 modules. 100G QSFP28 zoo li yog qhov tseem ceeb thiab feem ntau yog siv nyob rau hauv cov chaw luv luv (0-10 km) ntawm kev hloov mus lossis qee zaum hauv qhov chaw deb (mus txog 40/80 km) nrog QSFP28 ER4 / ZR4 thiab ib hom fiber ntau. Thaum lub sijhawm, txawm hais tias 100G CFP tuaj yeem siv rau hauv qhov chaw luv luv ib yam nkaus, nws muaj ntau dua hauv thaj chaw ntawm thaj chaw (MANs) thiab cov kis ntev ntawm WDM.
