100G ultra-ntev-ntev kis tau tus mobkho qhov muag moduleyog los,
2000km kis tsis tau yog npau suav!!!
Qhov kev ncua deb ntawm ib qho optical module yog qhov tseem ceeb parameter. Raws li kev xav tau ntawm kev lag luam thiab kev sib txuas ntawm kev sib txuas ntawm ultra-ntev-ntev kis tau tus mob, ultra-ntev-ntev kis tau tus mob kev daws teeb meem tau dhau los ua tus qauv tsim ntawm kev lag luam kev sib txuas lus yav tom ntej. Nyob rau hauv qhov tseeb siv ntawm ultra-ntev-ntev-distance optical modules, nws yuav raug txwv los ntawm lub cev obstacles xws li dispersion teebmeem thiab nonlinear teebmeem.
Rau cov ntawv thov tshaj 10km hauv 100G tes hauj lwm, muaj peb txoj kev daws teeb meem tseem ceeb:
100G ER4 (40km), 100G ZR4 (80km) thiab 100G DCO (2000km).
100G ER4 tuaj yeem ua tiav qhov kev ncua deb ntawm 40km, los ntawm kev siv lub tshuab hluav taws xob semiconductor (SOA) hauv lub transceiver kom nce nyiaj siv hluav taws xob. Lub transmitter tuaj yeem ua haujlwm ntawm plaub LAN WDM bands ntawm 1295nm, 1300nm, 1305nm thiab 1310nm. Cov teeb liab kho qhov muag hauv plaub pawg no yog multiplexed los ntawm WDM wavelength division multiplexer thiab xa mus rau ib hom fiber ntau los ntawm duplex LC connector. Thaum kawg tau txais, SOA nthuav tawm lub teeb liab ua ntej nws tawg mus rau hauv ib tus neeg raws los ntawm WDM wavelength division multiplexer.
Qhov ntxov tshaj 100G ER4 optical modules siv CFP thiab CFP2 pob, tab sis vim qhov loj me thiab kev siv hluav taws xob, thiab cov hloov tshiab 100G optical keyboards feem ntau yog nruab nrog compact QSFP28 ports es tsis txhob loj CFP interfaces, lawv tsis tshua siv nyob rau hauv 100G ntev- nrug siv lawv nyob rau hauv daim ntawv thov. Yog li ntawd, kev ua lag luam yog ntau inclined siv high-density 100G QSFP28 modules kom muaj peev xwm thiab txo qhov chaw, siv zog thiab tu nqi.
100G ZR4
Lub 100G ZR4 tuaj yeem xa mus rau 80km, thiab plaub-channel serial cov ntaub ntawv (NRZ) ntawm qhov kawg kis tau zoo los ntawm CDR thiab dhau mus rau plaub lub laser tsav tsheb, uas tswj plaub lub lasers nrog nruab nrab wavelengths ntawm 1296nm, 1300nm, 1305nm thiab 1309nm feem. Optical signals yog multiplexed rau ib hom fiber ntau los ntawm tus qauv LC connectors.
Thaum qhov kawg tau txais, cov teeb liab kho qhov muag ntawm plaub txoj kab tau nthuav dav los ntawm SOA, thiab tom qab ntawd cov teeb liab kho qhov muag yog demultiplexed los ntawm kev sib xyaw kho qhov muag demultiplexer. Txhua lub teeb liab kho qhov muag tau rov qab los ntawm tus PIN ntes thiab tom qab ntawd dhau los ntawm lub tshuab hluav taws xob transimpedance thiab CDR mus rau CAUI-4 cov neeg tsav tsheb ua raws cov zis. Ib yam li ntawd, kev ua lag luam nyiam 100G ZR4 hauv QSFP28 pob.
100 G DCO
Kev siv kis tau tus mob tshaj 80km yuav tsum tau siv cov txheej txheem kev sib txuas lus. 100G DCO yog ib qho ntawm ob peb txoj kev xaiv rau 100G optical transmission applications tshaj 80km txog 2000km. 100G DCOs muaj nyob rau hauv CFP thiab CFP2 pob. Ntawm lawv, CFP2 DCOs muaj kev hloov pauv ntau dua thiab txhawb nqa cov vaj huam sib luag siab dua li CFP DCOs.
CFP2 DCO siv QP-QPSK modulation thiab, ua tsaug rau built-in DSP, tsis xav tau ib tug cais Dispersion Compensation Module (DCM), tab sis cia li muaj hluav taws xob dispersion nyiaj them, ua kom nws kis tau ntev ntawm qhov chaw amplification. Optical module suav nrog optical multiplexers thiab Mach-Zehnder modulators, receivers muaj xws li kho qhov muag demultiplexers, dual InP 90 degree optical hybrid mixers, thiab ib qho kev sib npaug PIN photodetector thiab quad-channel TIA.
Lub 100G CFP2 DCO yog muaj nyob rau hauv peb lub versions, ZR / MR / LH, tag nrho nyob rau hauv ib tug compact CFP2 pob thiab ib tug paub tab 16nm DSP. Ntawm lawv, qhov kev ncua deb ntawm ZR hom yog 120km, qhov kev ncua deb ntawm MR hom yog 300km, thiab kis tau tus mob ntawm LH hom yog 2000km.
Kev tsiv teb tsaws chaw tam sim no network infrastructure mus rau 100G systems yog qhov kev zam, thiab ntau thiab ntau lub lag luam xav tau 100G cov neeg siv khoom sib cuam tshuam kom txuas ntxiv mus ntev dua yam tsis tas siv cov khoom siv hluav taws xob kim kim, 100G ER4, ZR4 thiab DCO txaus siab rau cov kev xav tau no.
Nws muaj nyob rau hauv 100G QSFP28 ER4, 100G QSFP28 ZR4 thiab 100G
CFP / CFP2 DCO tuaj yeem npog tag nrho 100G ultra-ntev nrug ntawm kev sib txuas ntawm qhov sib txuas hauv 40km txog 2000km.
