Tshawb xyuas plaub qhov tseem ceeb ntawm cov chaw khaws ntaub ntawv rau cov khoom siv kho qhov muag

Tam sim no, cov tsheb khiav ntawm lub chaw khaws ntaub ntawv tab tom nce ntxiv, thiab qhov bandwidth ntawm lub network tau hloov kho tas li, uas coj cov cib fim zoo rau kev txhim kho cov khoom siv optical ceev. Cia kuv tham nrog koj txog plaub qhov kev xav tau tseem ceeb ntawm lub chaw khaws ntaub ntawv tiam tom ntej rau cov khoom siv optical.

1. Kev kub ceev, txhim kho bandwidth peev xwm

Lub peev xwm hloov pauv ntawm cov chips hloov pauv yuav luag ob npaug txhua ob xyoos. Broadcom tau txuas ntxiv tsim Tomahawk series ntawm cov chips hloov pauv txij li xyoo 2015 txog 2020, thiab lub peev xwm hloov pauv tau nce ntxiv los ntawm 3.2T mus rau 25.6T; nws xav tias los ntawm xyoo 2022, cov khoom tshiab yuav ua tiav 51.2T kev hloov pauv peev xwm. Tus nqi chaw nres nkoj ntawm cov servers thiab cov switches tam sim no muaj 40G, 100G, 200G, 400G. Tib lub sijhawm, tus nqi kis tau ntawm cov modules optical kuj tseem nce ntxiv, thiab nws hloov kho dua tshiab hauv kev coj ntawm 100G, 400G, thiab 800G.

2. Siv hluav taws xob tsawg, txo cov cua sov

Kev siv hluav taws xob txhua xyoo ntawm cov chaw khaws ntaub ntawv loj heev. Kwv yees tias xyoo 2030, kev siv hluav taws xob ntawm chaw khaws ntaub ntawv yuav suav txog 3% txog 13% ntawm tag nrho kev siv hluav taws xob thoob ntiaj teb. Yog li ntawd, kev siv hluav taws xob tsawg kuj tau dhau los ua ib qho ntawm cov kev xav tau ntawm cov khoom siv kho qhov muag ntawm chaw khaws ntaub ntawv.

3. Kev ceev ceev, txuag qhov chaw

Nrog rau qhov nce ntxiv ntawm kev sib kis ntawm cov khoom siv kho qhov muag, piv txwv li 40G cov khoom siv kho qhov muag, qhov ntim thiab kev siv hluav taws xob ua ke ntawm plaub lub khoom siv kho qhov muag 10G yuav tsum ntau dua li 40G cov khoom siv kho qhov muag.

4. Tus nqi qis

Nrog rau qhov nce ntxiv ntawm lub peev xwm hloov pauv, cov neeg muag khoom siv loj uas paub zoo tau qhia txog 400G hloov pauv. Feem ntau tus lej ntawm cov chaw nres nkoj ntawm lub hloov pauv yog qhov ntom heev. Yog tias cov khoom siv kho qhov muag tau txuas rau hauv, tus lej thiab tus nqi yog loj heev, yog li cov khoom siv kho qhov muag pheej yig dua tuaj yeem siv rau hauv cov chaw khaws ntaub ntawv ntawm qhov loj dua.
