Cabling kev xaiv rau 40G Data Center
Nws paub tag nrho tias SFP thiab SFP + feem ntau siv rau 1G thiab 10G network, thaum QSFP nquag siv rau 40G network. Lub interface hloov yuav tsum sib txawv connectors mus cuag network connectivity. Txhawb 40G network, dab tsi yog qhov ua kom cov khoom siv cab? Cov tshooj no yuav tham txog cov kev xaiv cabling rau 40G qhov chaw khaws ntaub ntawv.
Tus qauv IEEE 802.3BA qhia txog MPO (multifiber push-on) connectors rau kev sib txuas ntev ntawm kev sib txuas ntawm fiber ntau multimode. MTP / MPO yog qhov kev tsim interface rau multimode 40G. Nrog me me, daim ntawv ceev xwm txheej, nws zoo tagnrho nrog cov khoom siv qis dua Ethernet. Lub 12-fiber MPO connector interface tuaj yeem ua tau 40G, uas feem ntau yog siv 40G qhov chaw nruab nrab. Cov kev coj siv ntawm MPO ntsaws-thiab-ua si nruab ntu 12-fiber ntau mus rau rau raws li uas khiav mus txog 10 Gigabit Ethernet (nyob ntawm qhov ntev ntawm qhov cable). 40G system siv 12-fiber ntau lub cev los tsim txawb / Rx txuas, dedicating 4 fibers rau 10G txhua kis ntawm kis mus qis, thiab 4 fibers rau 10G txhua qis txais. Txoj kev hloov tshiab rau hom kab ke no tsuas yog siv lub cassette nrog MPO-los-MPO adapter module.
Dhau li ntawm MTP / MPO pob tw los yog tej thaj chaw sib txuas ua ke uas txuas nrog QSFP + cov neeg sib tw, 40G ncaj xa cov cab kuj tseem siv nyob rau hauv cov ntaub ntawv chaw. DAC yog ib daim ntawv ntawm kev kub ceev txuas nrog "hloov dua siab tshiab" rau ob hnub siv los txuas nrog cov keyboards rau routers los yog servers. Nws yog ib hom optical transceiver sib dhos. Tso ncaj qha cab cab tsis yog tiag tiag optics thiab lawv cov khoom yog tsis muaj qhov muag lasers. Nrog tus nqi qis dua thiab kev ua tau zoo dua li cov kev siv hluav taws xob, kev xa ncaj qha rau cov xaim rau 40G qhov chaw nruab nrab cov ntaub ntawv thiab kev ua haujlwm siab. Tus nqi ntawm kev sib txuas yog txo los ntawm kev zam cov nqi hluav taws xob ntau dua thiab cov cab muag kho qhov muag. 40G DACs tuaj yeem muab kev sib txuas tsis muaj nqi thiab txhim khu kev qha 40G siv siv cov nquag optical cables lossis tooj liab cab.
Tus kabmob kho qhov muag muaj ib qho khoov-khavthawj ntau suab paj nruag los sis ib hom kab hlau txuas cable nrog ib lub connector thiab kos nrog cov xa tawm uas hloov hluav taws xob teeb liab kom pom qhov teeb meem thiab rov qab. Siv cov kev txuas tib yam li tooj liab, AOC tuaj yeem ncav cuag lub nkoj ntev dua tooj liab, thiab feem ntau yog siv nyob rau hauv cov ntaub ntawv chaw. Tom qab cov lus teev Fiberstore nquag nquag siv kho qhov yooj yim nrog cov qauv nruab nrog cov kev kawm siab, tsis muaj hwj huam tau kev sib qheb mus rau kab kev sib txuas nrog cov kab ke ntau hom kab ke thiab kev sib txuas lus sib txuas.

Cov cab cab tooj tshwj xeeb yog tsim los rau luv-reaches nyob rau hauv cov ntaub ntawv chaw. Lawv tsis tshua kim tshaj cov cab cab. Niaj hnub no muaj ntau ntau tus cabinaxial cables txhawb 40G (10G x plaub raws), ib qho kev qhia 40GBASE-CR4. Cov lus qhia nram qab no qhia Fiberstore tus nqi hluav taws xob khov uas muaj chaw ntau qhov chaw rau cov chaw zov me nyuam.

MTP / MPO fiber cables thiab 40G QSFP + cables yog kev xaiv zoo rau 40G cov ntaub ntawv chaw. FOCC muab tag nrho cov cables uas muaj qhov zoo thiab kev sib tw. Tshaj li ntawd, cov xa ncaj qha rau cov cables raug sim nyob rau hauv cov ntawv siv los ua kom paub tseeb zoo tshaj plaws. Yog xav paub ntxiv, thov mus xyuas www.focc-fiber.com
