Txhua tus engineer network tsoo tib phab ntsa thaum kawg. Tsheb khiav dashboards pib tig liab thaum lub sij hawm ua hauj lwm. Cov haujlwm khaws cia rov ua dua los ntshav rau tag kis. Virtual tshuab migrations uas siv sijhawm vib nas this tam sim no nkag. Cov no yog cov lus ceeb toom ntxov uas koj 10G infrastructure tab tom khiav tawm ntawm lub taub hau, thiab cov koom haum feem ntau pom lawv 12 txog 18 lub hlis ua ntej qhov mob tiag tiag pib.
Kev tsiv teb tsaws chaw los ntawm 10G rau 100G Ethernet tsis yog ib lo lus nug ntawm seb, tab sis thaum twg thiab yuav ua li cas. Cov neeg ua haujlwm Hyperscale tau tsiv mus rau 100G data center fabrics xyoo dhau los. Xyoo 2026, nrog NVIDIA DGX H100 SuperPODs xav tau 400G thiab 800G txuas rau GPU- mus rau -GPU tsheb, 100G tau hloov pauv los ntawm ntshav- ntug kev xav kom paub tab, tus nqi{13}} kho kom zoo rau kev lag luam. Qhov ntawd yog qhov tseeb xov xwm zoo: thev naus laus zis tau raug pov thawj, optics pheej yig, thiab cov ntawv xa tawm tau zoo tsim.
Qhov kev sib tw tsis yog yuav khoom siv ceev dua. Qhov kev sib tw yog npaj kev tsiv teb tsaws chaw uas tiv thaiv koj cov peev txheej uas twb muaj lawm, zam kev tsis tsim nyog poob qis, thiab tso koj lub network rau lub voj voog nrawm tom ntej tom qab 100G.
Qhov twg 100G Fits hauv 2026 Speed Landscape
Nws pab tsim 100G hauv cov ntsiab lus. Nyob rau sab saum toj kawg ntawm kev ua lag luam, AI kev cob qhia pawg tau siv bandwidth ntawm tus nqi staggering. Ib qho NVIDIA DGX H100 SuperPOD nrog 32 servers siv kwv yees li 256 units ntawm 400G optical modules ntawm servers thiab nplooj hloov pauv, ntxiv rau 640 units ntawm 800G modules ntawm tus txha nraub qaum. Cov pawg no kho 400G raws li kev nkag mus ceev. Rau cov lag luam, txawm li cas los xij, 100G tseem yog qhov chaw qab zib rau kev sib sau ua ke, kev sib tshuam - hloov lub cev, thiab cov pob txha khaws cia - qib nrawm qhov twg tus nqi, kev ntseeg siab, thiab kev loj hlob ntawm ecosystem tag nrho. Xaiv100G QSFP28 transceiversniaj hnub no muab cov nqi khoom muag rau koj thiab ntau - tus neeg muag khoom sib cuam tshuam uas qhov nrawm dua tseem tsis tau txog.
Ntsuam xyuas koj qhov tam sim no 10G Infrastructure Ua ntej lwm yam
Kev vam meej 100G tsiv teb tsaws pib nrog cov khoom muag ncaj ncees. Cov ntaub ntawv txhua qhov hloov pauv, transceiver, fiber ntau khiav, thiab thaj vaj huam sib luag. Cov koom haum uas hla cov kauj ruam no niaj hnub nrhiav pom cov ntaub ntawv tsis muaj kev vam khom thaum lub sijhawm kho qhov rais - raws nraim thaum koj tuaj yeem them taus qhov xav tsis thoob.
Ua tib zoo saib xyuas koj cov nroj tsuag fiber ntau. Yog tias koj lub chaw khaws ntaub ntawv tau tsim nyob ib puag ncig OM3 lossis OM4 multimode fiber ntau rau 10G luv- mus txog qhov txuas, cov cables feem ntau tuaj yeem txhawb nqa 100G hla qhov deb mus txog 70-100 meters siv 100GBASE-SR4 optics. Qhov ntawd yog xov xwm zoo rau kev sib txuas hauv -. Rau kev khiav ntev dua 100 meters, koj yuav xav tau hloov mus rau ib qho - hom fiber ntau, tshwj xeeb yog tias koj tab tom siv 100GBASE-LR4 lossis ER4 modules rau kev sib txuas hauv tsev -.
Ib lo lus ceeb toom los ntawm kev xa mus rau kuv tau koom nrog: peb muaj ib tus neeg siv khoom tsiv kab ntawm nplooj hloov mus rau 100G SR4 siv lawv cov OM4 MPO lub cev cables uas twb muaj lawm. Ib nrab qhov txuas tsis kam tuaj. Lub hauv paus ua rau tsis yog fiber ntau lossis optics - nws yog polarity. Lawv cov MPO cables yog Hom A, tab sis tus neeg muag khoom hloov tshiab xav tau Hom B polarity ntawm QSFP28 cov chaw nres nkoj. Cov xaim fibers tau tsaws rau ntawm tus pins ntawm ob qho kawg. Peb siv plaub teev nyob rau hnub Saturday tsaus ntuj swapping polarity{10}}fipping adapters ua ntej txhua qhov txuas tau huv. Qhov kev saib xyuas ib zaug - yeej tsis kuaj xyuas MPO polarity matrix tiv thaiv cov khoom siv tshiab - raug nqi ntau dua hauv kev ua haujlwm kub ntxhov ntau dua li optics lawv tus kheej. Nco ntsoov xyuas polarity ua ntej koj rack dab tsi.
Xaiv txoj kev tsiv teb tsaws chaw txoj cai
Kev pom zoo kev lag luam tau hloov pauv kom meej meej hauv kev pom zoo ntawm 10G-25G-100G txoj hauv kev dhau 10G-40G-100G txoj kev qub, thiab kev sib piv ceev qhia tias yog vim li cas.
