Aug 20, 2025| Cov Evolution ntawm Optical interconns ntawm Cov Chaw Teev Khoom Niaj Hnub
Tshawb nrhiav lub luag haujlwm tseem ceeb ntawm cov ntaub ntawv nruab nrab kev daws teeb meem hauv kev tiv thaiv peb hyperconnected digital kev khwv nyiaj txiag
Hauv lub ntiaj teb no hyperconnected hyperconnected ntiaj teb, cov ntaub ntawv chaw pab ua tus caj qaum ntawm peb cov kev lag luam digital, thiab ua rau cov kev paub txog kev lag luam digital uas peb xav tau. Raws li cov chaw no txuas ntxiv loj hlob hauv ob qho loj thiab qhov tseem ceeb, thev naus laus zis uas txuas rau lawv cov kev daws teeb meem lossis kev ua haujlwm thiab ua haujlwm tau zoo.
1.1 kho qhov muag interconnnts hauv cov chaw teev
Lub plawv ntawm Niaj hnub nimno cov chaw nruab txuas cov lus dag hauv kev kho qhov muag thev naus laus zis. Tsis zoo li ib txwm tooj liab - Kev siv lub teeb pom kev yooj yim, muaj cov khoom siv nrawm nrawm, muab cov peev xwm tsis pom zoo thiab bandwidth muaj peev xwm. Qhov no hloov pauv hauv kev sib hloov thev naus laus zis tau hloov kho cov ntaub ntawv kev lag luam uas tau ua haujlwm, ua rau lawv los daws cov cim kev sib raug zoo hauv cov teeb meem ntawm cov ntaub ntawv uas muaj txiaj ntsig.
Kev sib txuas ntawm kho qhov muag tsis pub dhau cov chaw zov me nyuam feem ntau ua haujlwm nyob rau hauv cov servers {{1} {- khib sib txuas thoob plaws lub chaw. Kev saws me nyuam ntawm cov kev daws teeb meem tau tsav los ntawm ntau yam, suav nrog kev xav tau rau bandwidth ntau dua, thiab txhim kho kev ua tau zoo.
Cov physics tom qab qhov kis tau muag dua ntawm qhov muag muaj qhov ua tau zoo dua cov cim hluav taws xob. Lub teeb pom kev ua rau muaj kev cuam tshuam kom tsawg, tsis txhob muaj ntau lub wavelengtions ib txhij los ntawm ib txheej txheem hu ua wavelength division multiplexing (WDM).
