Tom qab xyoo dhau los ntawm kev txhim kho, kev kho qhov tseeb thiab pluggable optical module tau dhau los ua cov kev xaiv tsis yooj yim ntawm kev sib txuas lus kho kab kev sib txuas lus sab kev pabcuam kis. Kev tsim kho tag nrho ntawm kev sib xyaw ua ke lub teeb pom kev zoo siv rau cov nroog hauv nroog thiab cov caj qaum qaum yog: ua ntej, kev kub ceev, ntawm 100G rau 400G, thiab tom qab ntawd mus rau 800G; Thib ob, miniaturization, los ntawm 100G MSA daim ntawv ntim mus rau CFP / CFP2 DCO / ACO cov ntawv ntim khoom, kev lag luam tam sim no tau thov 100G / 200G / 400G OSFP DCO thiab QSFP-DD DCO ntim qauv; Thib peb, kev siv hluav taws xob tsawg. Xav txog qhov yuav tsum tau ua lub zog ntawm tag nrho cov kab ke, kev siv fais fab ntawm qee qhov encapsulated coherent optical module khoom yuav tsum tsis pub siab tshaj 18W. Plaub yog qhov kev ntsuas ntawm kev sib tshuam. Kev lig kev cai, txhua qhov chaw tsim khoom siv USES tus kheej tsim tshwj xeeb cov pawg tswj hwm tus kheej thiab tus kheej qhov kev txiav txim siab tshaj tus qauv thiab FEC algorithm, yog li qhov cuam tshuam ntawm cov tuam ntxhab sib txawv tsis tuaj yeem ua haujlwm.
Nrog txoj kev loj hlob ntawm kev lag luam Is Taws Nem, kev tsim kho ntawm huab hwm huab thiab qhov kev thov ntawm AI laij, kev sib tham hauv telecom thiab cov chaw khaws ntaub ntawv tau muab cov kev xav ua kom tiav rau cov kev cuam tshuam ntawm cov kho qhov muag ntawm cov muag khoom sib txawv. Hais txog FEC tus qauv, txawm hais tias muaj ntau hom xws li GFEC, SCFEC, RS10, CFEC, OFEC, SDFEC, KR4-FEC thiab KP4-FEC, sib thooj rau cov nqi sib txawv thiab cov qauv, tag nrho cov kab ke muaj peev xwm muab faib ua peb tiam neeg. Cov thawj tiam yog block code, nrog 6dB nce qhov yuav tsum tau thiab 6.69% nyiaj siv ua haujlwm. Qhov ob-tiam cascade interleave iteration yuav tsum tau 8dB nce thiab 6.69% nyiaj siv ua haujlwm. Lub cim thib peb ntawm kev txiav txim siab muag muag SDFEC, nrog nce xav tau ntawm 11dB thiab nyiaj siv ua haujlwm ntawm 15% -20%, txais Turbo cov khoom lag luam code (TPC) thiab tsis tshua muaj qhov siab parity kos code (LDPC) algorithm, thaum lub sijhawm tshiab ntawm FEC raws qhov kev kwv yees qhov tseeb ntawm constellation tsis tau tso tawm raws li tus qauv rau lub sijhawm ua. Hauv MIS cov qauv, tseem muaj ntau hom CFP MIS, C-CMIS thiab CMIS cov qauv.
Kev sib piv tshawb xyuas ntawm 400G kev sib haum xeeb
Lub 400G coherent optical module tam sim no muaj peb tus qauv: OIF-400g ZR, OpenRoadm thiab OpenZR +. Oif-400g ZR lub hom phiaj yog thov hauv ntug DCI. Tsuas yog 400GbE tus nqi txhais tau rau sab tus neeg siv, thiab kis tau deb yog 80km. CFEC saws rau kev txhim kho rau pem hauv ntej. OpenRoadm MSA feem ntau yog siv rau cov kev sib txuas xov tooj' ROADM network ntawv. Nws txhais tau meej 100G, 200G, 400GbE tus nqi& OTN rau ntawm cov neeg siv khoom, thiab cov kis deb yog 500km. Nws txais OFEC rau pem hauv ntej kev txhim kho kev txhim kho algorithm. Ntawm qhov tod tes, OpenZR + MSA muaj ntau daim ntawv thov dav dav, tig mus rau thaj chaw hauv nroog, thiab nraub qaum, DCI thiab cov tuam txhab sib txuas lus. Nws txhais tau 100G, 200G thiab 400GbE ntau tus nqi ntawm cov neeg siv khoom kom tau raws li qhov chaw sib kis ntawm cov chaw hauv nroog lossis cov chaw nyob ntev, thiab siv cov kev txhim kho tom ntej kev txhim kho ntawm OFEC. Nws tuaj yeem pom tias OpenZR + yog MSA tus qauv qhia los ntawm kev nqus cov khoom zoo ntawm oIF-400G ZR thiab OpenRoadm cov qauv. Qhov tseeb tshaj ntawm OpenZR + tau tso tawm lub Cuaj Hlis 2020.
Kev txheeb xyuas txog qhov sib txheeb hloov pauv zuj zus ntawm 400G
Los ntawm qhov pom ntawm kev ua lag luam, nyob rau hauv cov nqe lus ntawm kev muag khoom, qhov kev loj hlob txhua xyoo ntawm kev ua lag luam DWDM thoob ntiaj teb yuav nce txog 20% txij xyoo 2020 txog 2025 thiab nce mus txog 2.5 txhiab daus las Asmeskas thaum xyoo 2025. Kev muag khoom ntawm 400G thiab siab dua cia siab tias yuav ncav cuag $ 150 lab nyob rau hauv 2020, nrog rau kev loj hlob txhua xyoo ntawm 19% tom qab ntawd, thiab nce mus txog $ 1.5 nphom hauv 2025, nrog qhov kev loj hlob sib piv ntawm 46%. 400GZR thiab 400GZR + yog cov pheej loj tshaj plaws, tom qab ntawd CFP2 DCO thiab 100G ZR, uas xav tias yuav ncav cuag peb li $ 6.6, 6.5, 4.2 thiab 290 plhom raws xyoo 2025, nrog rau kev lag luam tag nrho kwv yees li US $ 2.3 billion. Hais txog kev xa khoom, 400G ZR, 100G ZR, CFP2 DCO, thiab 400G ZR + cov khoom xa khoom loj hlob sai, nrog 400G ZR / ZR + kev xa khoom xav tias yuav muaj txog 6,000 nyob rau xyoo 2020 thiab 550,000 hauv 2025, thaum 400 / 600 / 800g OnBoard xav tias yuav muaj 15,000 nyob rau xyoo 2020 thiab 40,000 hauv 2025. Hauv 2025, tus lej ntawm 400G ZR +, 100G ZR +, 200G ZR + thiab 400G ZR { {59}} vam tias yuav ncav cuag 330,000, 320,000, 240,000 thiab 220,000 feem.
Los ntawm qhov pom ntawm kev siv thev naus laus zis, cov tiam tom ntej ntawm ultra-400g coherent khoom yuav txais cov thev naus laus zis xws li ib nthwv 800G, DP-16qAM, 5nm DSP, silicon optical technology thiab Flip Chip thev naus laus zis. Cov khoom tsim hluav taws xob tom ntej hluav taws xob interface Baud yuav nce mus txog 4 * 128GHz, kho qhov muag tiv thaiv COSA siv DDP -16QAM kev hloov kho kom ua tiav 128GHz Baud, TIA / Tsav bandwidth yuav nce mus txog 96GHz. 800G ZR xav tau txog 29dB OSNR, thaum 800G ZR + yuav tsum muaj 25dB OSNR.
