Ua tiav qhov muaj peev xwm thiab tus nqi qis rau 400GbE yog qhov tseem ceeb rau cov neeg ua haujlwm hauv lub network, cov tshuab ua tshuab, cov muag khoom muag, cov router thiab hloov cov neeg muag khoom, thiab ntau lwm tus tswvcuab hauv cov kab ke kho qhov muag. Tshwj xeeb, ib qho laj thawj rau kev ua tiav kev sib tw ntawm 400GbE yog qhov sib hloov ntawm tus nqi thiab PMD ntawm IEEE, OIF, thiab ntau qhov chaw raws tu qauv (MSA) cov tswv cuab. Hmoov tsis zoo, kev lag luam thaum xub thawj muaj ob lub ntim khoom ntim tau yooj yim, uas ua rau kev rov tsim kho thiab tsim khoom. Qhov luam tawm no tej zaum yuav txo qhov kev lag luam lub peev xwm los txuas ntxiv cov kev daws teeb meem.
Qhov pib ntawm 400GbE pib hauv 2019 thiab yuav nce sai. Qhov kev sib cav txog daim ntawv ntawm lub ntsej muag kho qhov muag ntim tau yog loj dhau lawm, thiab seb cov neeg muag khoom puas tau xaiv qsfp-dd lossis ob qho tib si, qhov kev tsom xam tam sim no hloov mus rau yav tom ntej kev nrawm. Hauv lub sijhawm ntev, 400GbE yuav tsuas yog xaiv qsfp-dd. Raws li kev lag luam txuas ntxiv txuas qsfp-dd, kev lag luam ntawm nplai yuav tshwm sim thiab 400GbE yuav ncav cuag nws lub peev xwm.
