Raws li tsab ntawv tshaj tawm tshiab los ntawm lub tuam txhab tshawb fawb kev lag luam Dell'Oro, tiam tom ntej ntawm terabit -theem DSP chips yuav pab DWDM cov cuab yeej ua lag luam ncav cuag kev lag luam loj ntawm $ 18 nphom hauv tsib xyoos tom ntej. Jimmy Yu, VP ntawm Dell'Oro, tus sau tsab ntawv ceeb toom, taw qhia tias cov terabit - qib DSPs yuav raug siv rau hauv ntau lub network, los ntawm cov chaw zov me nyuam rau cov chaw me me thiab nruab nrab- cov neeg ua haujlwm hauv xov tooj. Qee cov neeg siv lawv rau ib zaug - wavelength 1Tbps kis tau tus mob, thaum lwm tus siv lawv ntev dua - kis tau tus mob.
Jimmy Yu tshwj xeeb sau tseg tias cov neeg ua haujlwm hauv Suav teb yuav siv cov chips no kom ua tiav 400Gbps ultra-ntev{2}} kis tau tus mob, thaum ntau tus tswv yuav siv lawv rau 800Gbps daim ntawv thov ntawm qhov luv luv. Hauv tsib xyoos tom ntej no, ntau tshaj ib nrab ntawm cov peev txheej ntxiv yuav raug tsav los ntawm DWDM systems raws li qib thib rau - tiam DSP.
Xyoo tas los, Dell'Oro tau qhia tias qhov kev thov rau cov khoom siv kho qhov muag yuav ntau dua $ 83 nphom hauv tsib xyoos tom ntej, feem ntau yog tsav los ntawm cov khoom siv DWDM sib koom ua ke hauv nroog loj thiab ntev -DCI daim ntawv thov nyob deb, qhov ntev - cov khoom siv thauj khoom tuaj yeem ua rau muaj txiaj ntsig zoo rau kev lag luam tag nrho.
Qee lub tuam txhab twb tau pib dov tawm Tbps - cov khoom siv kho qhov muag. Thaum lub Cuaj Hlis xyoo tas los, Cisco yog thawj tus los qhia txog NCS 1014 C-band 2.4T WDM kab ntawv tshiab, koom tes nrog Windstream kom ua tiav 1Tbps kis tau tus mob tshaj 1100 mais. Ciena kuj tau tshaj tawm cov phiaj xwm los tshaj tawm WaveLogic 6 nti, txhawb nqa 1.6Tbps 1000km kis tau tus mob, hauv thawj ib nrab ntawm 2024. Los ntawm 2028, nws xav tias ntau tshaj li ib nrab ntawm DWDM cov khoom muag yuav los ntawm 1.2Tbps thiab 1.6Tbps kab phaib. Cov kab ntawv no tuaj yeem txhawb nqa lub peev xwm sib kis tau ntau dua, yog li txo tus nqi ib me ntsis, muaj qis dua ntawm -ntsis siv hluav taws xob, thiab txhawb lub neej yav tom ntej.
Dell'Oro tseem kwv yees tias kev kis tus kab mob siab baud yuav dhau los ua ntau dua. Los ntawm 2028, cov tshuab nrog baud tus nqi siab tshaj 100GHz yuav suav txog ntau dua 40% ntawm kev xa tawm tshiab. High baud tus nqi muab kev ua tau zoo dua, kev ncua ntev, cov nqi qis dua, thiab tseem yuav ua rau muaj kev siv ntau dua ntawm C + L band, raws li kev taw qhia ntawm tus nqi siab baud yuav txo cov kev muaj nyob hauv cov tsoos C band.
