100g qsfp28 sr4 vs. LR1 kho kho qhov muag: Kev qhia nrawm rau kev xaiv zoo
Raws li cov chaw zov me nyuam hloov zuj zus, xaiv ntawm 100g QSFP28 SR4 thiab LR1 kho qhov hloov kho kho qhov muag tau ua tus nqi tseem ceeb. Ntawm no yog cov lus sib piv los qhia rau koj qhov kev txiav txim siab:
Tub Ntxhais Sib Txawv
- SR4: optimized rau kev sib txuas luv luv-ntau (MMF) sib txuas, zoo nkauj rau kev sib txuas khib nyiab zoo nkauj, zoo rau cov khoom lag luam high hauv cov ntaub ntawv.
- LR1: Tsim rau ib leeg-hom fiber ntau-fiber ntau (smf) nrog 1310nm ncav cuag, nws ua tiav rau kev sib txuas lus lossis cov kab ke hla kev sib txuas.
2. Daim Ntawv Thov Kev Sau Npe
- SR4 exhels nyob rau hauv tus nqi-rhiab, high-ntom ib puag ncig zoo li AI kev cob qhia pawg lossis cov chaw zov me nyuam lossis cov chaw haujlwm hyperscale qhov twg<100m links dominate.
- LR1 ci nyob rau hauv ntev ntev kev sib tw huab, xws li txuas cov khoom xa hluav taws xob lossis 5g tus tseem ceeb ntawm ib leeg-wavulife ib-wavulife ib-wavulate ib-wavulify pam4 kev hloov kho.
Tseem Ceeb Lag Luam-Offs
- SR4: Txo tus nqi qis dua, txwv tsis pub ncua deb.
- LR1: Ntau dua mus txog nrog kev siv fais fab
