Nyob rau xyoo 2020, kev tsim kho cov ntaub ntawv nruab nrab yuav dhau los ua ib lub zog tseem ceeb rau kev tsim kho kev lag luam sib txuas lus thoob plaws lub xyoo. Xyoo tsis ntev los no, kev lag luam cov ntaub ntawv kev sib txuas lus tau dhau los ua qhov chaw sib tw rau txhua lub lag luam hauv kev sib txuas lus kho qhov muag kev lag luam. Ua cov lag luam tshaj lij ntawm kev sib txuas lus kho qhov muag module, HTF muaj kev txhim kho sib sib zog nqus thiab kev sib tw zoo hauv kev sib txuas lus ntawm cov ntaub ntawv. Raws li nthwv dej ntawm Tuam Tshoj' s lub zog kev tsim kho tshiab ntawm kev tsim kho tshiab, nyob rau xyoo 2021, ib puag ncig tshiab ntawm cov cai tswjfwm yuav txhawb kev tsim kho ntawm Tuam Tshoj' s cov ntaub ntawv chaw rau pib siv hauv cov hauv kev tshiab txhim kho. Nyob rau hauv lub neej yav tom ntej, cov chaw khaws ntaub ntawv yuav tsum txhim kho lawv cov nplai, kev muaj peev xwm thiab kev tsim kho kom ruaj khov los ntawm ntau yam. Kev tsim kho thiab tsim tawm ntawm cov chaw zov me nyuam cov ntaub ntawv muaj kev cuam tshuam zoo rau cov khoos phis tawm kho qhov muag.
Kev loj hlob hauv kev nqis peev kho choj ua rau tsav tsheb xav tau rau cov kho qhov muag
Nrog rau kev tsim kho thev naus laus zis, kev siv nyiaj txiag hauv kev siv nyiaj hauv cov kev sib txuas lus tau tab tom hloov ntau yam. Nyob rau hauv xyoo tas los, kev sib koom tes lag luam yog txo kev nqis peev hauv cov khoom lag luam tsoos IT thiab software, thiab nyiam rau outsource rau cov chaw muab huab. Txoj kev loj hlob sai ntawm kev nqis peev hauv cov data center infrastructure, txuas nrog kev tsim kho sai ntawm cov qauv tshiab hauv Suav teb, cov chaw tshawb fawb txog kev lag luam xav tau ntau tshaj 20% kev loj hlob ntawm cov ntaub ntawv chaw tsim kho hauv ob peb xyoos tom ntej no. Txawv teb chaws, cov huab saum toj kawg nkaus tsib siv nyiaj $ 26.4 nphom hauv thawj peb lub hlis xyoo 2020, nce 56% los ntawm 2019.
Kev siv nyiaj rau kev lag luam muaj kev cuam tshuam rau kev loj hlob ntawm lub ntiaj teb kev lag luam ntawm cov khoos phis tawm ntawm cov khoos phis tawm kho qhov muag, rau cov chaw loj loj cov ntaub ntawv, kev loj hlob tsav lub teeb module thov kev loj hlob, tus nqi ntawm lub teeb module los ntawm 100 g rau 200 g rau 400 g evolution, raws li kev lag luam cov chaw tshawb xyuas, xav pom txog xyoo 2021 txog 2025, cov ntaub ntawv chaw tsim teeb khw khw yuav rov qab rau txoj kev loj hlob ntxiv ob npaug.
Kev tshaj tawm ntawm kev xaiv cov photoelectric nti txhawb nqa kev hloov kho kom nrawm nrawm ntawm cov kho qhov muag hluav taws xob ceev
Hais txog kev hloov kho thev naus laus zis ntawm cov khoos phis tawm hauv cov chaw zov me nyuam, thawj qhov yuav tsum tau ntawm optical module hauv cov chaw zov me nyuam yog kev kub ceev, tus nqi qis, kev siv hluav taws xob tsawg, pob me thiab lub zog me. Data center network architecture yog hloov zuj zuj hauv cov kev taw qhia ncaj ncaj. Qhov kev hloov pauv no daws cov teeb meem ntawm lub sijhawm qeeb thiab ntsuas, tab sis ua rau cov kev nce tsheb ntau ntawm sab hnub poob-sab hnub poob, uas yuav tsum muaj kev sib txuas ntau thiab sai dua. Cov kev txhim kho ntawm kho qhov muag module ceev tau kom muaj kev sib koom ua ke ntawm photoelectric chip ceev. Xyoo 2013, 25G NRZ Serdes yog thawj qhov kev hloov pauv, uas txhawb nqa cov khoom xa khoom ntawm 100G QSFP28 module hauv 2015. Thawj 50G Pam4 Serdes streamer hauv 2017 coj mus rau thawj cov kev lag luam xa khoom ntawm 400G series optical modules hauv 2019; Hauv 2020, 100G Serdes ntws tseem yuav ua rau kev txhim kho ntawm 800G tus nqi kho qhov muag siv. Nws cia siab tias 200G Serdes streamers yuav tsav qhov kev hloov kho ntawm 1.6T optical modules hauv 2023. Cov kev hloov pauv ntawm cov ntaub ntawv nruab nrab tau muab faib ua peb tiam: 25GnRZ Serdes, 50G PAM4, thiab 100 / 200G Serdes sib raug rau 100G series ntawm optical module , 400G thiab 800G optical modules.
Cov kev sib txuas ntawm cov ntaub ntawv nruab nrab tau muab faib ua kev sib txuas lus tsis pub dhau hauv cov ntaub ntawv chaw thiab DCI kev sib txuas lus nruab nrab ntawm cov ntaub ntawv chaw. Kev sib txuas ntawm qhov sib txawv ntawm qhov sib txawv yuav tsum muaj ntau yam ntawm cov kho qhov muag daws teeb meem. Ntxiv rau qhov nce ntawm tus nqi ntawm qhov kho qhov muag kho qhov muag hloov zuj zus, cov lus taw qhia los ntawm NRZ mus rau PAM4 kom sib haum, cov kab ke kho qhov muag los ntawm 1 × 2 rau 1 × 4 thiab 1 × 8 kev hloov pauv, los ntawm cov ntaub ntawv xa khoom, 1 × 4 ntxiv.
Raws li 50G serdes, sib haum rau 100G / 400G optical modules, VCSEL optical chips rau 100-meter luv nrug kis, silicon photonics thiab EML yog cov kev daws teeb meem tseem ceeb rau ib leeg-wavelength 100G los ntawm 2 km rau 500 metres. DML cov phiaj xwm vim kev kho qhov muag chip linearity dispersion qhov teeb meem tseem raug kho kom zoo, tsis paub tab. Rau cov chips kho sib txawv, cov txheej txheem cai sib txawv. Rau ntau hom VCSEL, nws yog feem ntau COB, thaum rau EML thiab silicon optical, nws yog COC txuas. Kev kam rau ntawm silicon kho qhov muag txuas yog qhov nyuaj tshaj qhov ntawm ib hom. Cov thev naus laus zis nyuaj ntawm silicon teeb nthuav tawm qee qhov kev cov nyom.
