Taw qhia ntawm 40G optical module thiab DAC / AOC

Thaum siv 40G Ethernet, 40G QSFP + optical module thiab 40G DAC / AOC high-speed cable yog qhov kev xaiv tseem ceeb rau cov neeg siv feem ntau.

40G optical module npog muaj ntau hom qauv, tag nrho ntawm cov thib peb ntawm QSFP + optical module, QSFP + DAC / AOC high-speed cable tuaj yeem sib txuas nrog cov hom loj.

QSFP + thiab CFP optical modules

Yuav ua li cas xaiv txoj cai 40G optical module?

Nws tau pom zoo kom xaiv cov 40G optical module kom tsim nyog raws li qhov kev xa khoom tiag tiag.

1. Hauv daim ntawv thov luv luv, thaum kis kev sib kis tsawg dua 1000m, koj tuaj yeem xaiv QSFP 40G SR4, 40Gbase SR bidi, QSFP 40G csr4 lossis QSFP 40G univ optical module. Ob QSFP 40G SR4 thiab 40Gbase SR bidi optical module tuaj yeem ncav cuag kev sib kis qhov deb li ntawm 150 metres ntawm lub teeb tsa fiber ntau. Qhov sib txawv tsuas yog tias cov qub raug xa mus rau OM4 optical fiber jumper, thaum tom kawg kis mus ntawm duplex multimode jumper nrog LC txuas. QSFP 40G CSR4 yog kho dua tshiab ntawm QSFP 40G SR4 optical module. Qhov ntau kis tau deb ntawm OM4 fiber ntau jumper yog 400m. Ntxiv rau, QSFP 40G univ optical module tseem tuaj yeem xa 150 metres ntawm cov hom fiber ntau jumper thiab 500 meters txog 2000 meters ntawm tib hom fiber ntau jumper, tab sis cov kis nrug sib txawv ntawm tus xa khoom mus rau cov neeg xa khoom.

2. Hauv cov ntawv thov ntev, thaum kis kev sib kis ntau dua 1000 meters, koj tuaj yeem xaiv QSFP 40G plrl4, 40G plr4, WSP q40G lr4l, QSFP 40G LR4 thiab QSFP 40G Er4 optical modules. Ob QSFP 40G plrl4 thiab 40G plr4 optical module tau nruab nrog MTP / MPO cov khoom sib txuas. Lub qub tuaj yeem xa mus deb li 1km lossis 1.4km ntawm tib hom kho qhov muag, thaum tom kawg muaj qhov txuas txuas ntev txog 10km. Raws li rau WSP q40G lr4l, QSFP 40G LR4 thiab QSFP 40G Er4 optical modules txhua tus muaj cov haujlwm ua haujlwm ib yam: thawj multiplex plaub kis xa mus rau ib lub fiber, thiab tom qab ntawd multiplex plaub tau txais channel rau lwm lub fiber. Ntawm lawv, QSFP + ER4 module tuaj yeem xa mus rau qhov chaw siab tshaj 40 km ntawm ib hom fiber ntau jumper ..

Txheej txheem cej luam ntawm 40G QSFP + DAC txoj kev kub ceev cable

40G DAC yog txoj kev kub ceev nrog QSFP {{2}} cov khoom sib txuas ntawm ob qho kawg, uas feem ntau siv los txuas cov keyboards, routers thiab servers. Qhov ntau kis deb ntawm 40G DAC high-speed cable yog 15m, uas tuaj yeem ua tau raws li qhov luv luv kev sib txuas qhov yuav tsum tau ntawm cov chaw nruab nrab cov ntaub ntawv thiab kev ua tiav ntawm kev siv huab ua tiav. 40G DAC high-speed cable tuaj yeem muab faib ua 40G active high-speed cable thiab 40G passive high-speed cable. Qhov sib txawv tseem ceeb ntawm ob qho ntawm cov kev kub ceev cable yog seb puas muaj fais fab mov. QSFP {{14}} DAC passive high-speed cable yog cov khoom siv passive, uas tsis haus ib qho hluav taws xob thiab tsim kom muaj cua sov, thaum QSFP {{16}} DAC siab ua haujlwm siab cable xav tau lub zog kom ua haujlwm sab hauv Circuit Court thiab choj rau qhov kev ncua deb ntev. 40G DAC high-speed cables feem ntau yog muab faib ua ob hom: QSFP {{20}} rau QSFP {{21}} DAC high-speed cables thiab QSFP {{23}} mus rau 4 SFP + 1: 4 cov xov hluav taws xob loj.

Txheej txheem cej luam ntawm 40G QSFP + AOC txoj kev kub ceev cable

Vim tias nws txoj haujlwm ruaj khov thiab hloov tau yooj yim, 40G QSFP + AOC kev kub ceev hluav taws xob tuaj yeem hloov tooj liab cable rau qee yam, thiab tseem tuaj yeem siv rau hauv cov chaw siv cov ntaub ntawv thiab kev ua haujlwm siab hauv lub network wiring. QSFP + AOC high-speed cable tuaj yeem txhais tau tias yog tus jumper fiber ntau nrog 40G qhov kub ceev txuas ntawm ob qho kawg. Nws siv photoelectric hloov dua siab tshiab kawg ntawm lub cable los txhim kho kis deb ntawm lub cable. Tam sim no, ntau yam ntawm QSFP + AOC high-speed cables rau 40G Ethernet tau tsim tawm hauv kev ua lag luam, xws li 40G QSFP + rau QSFP + AOC high-speed cable, 40G QSFP + txog 4-SFP 1: 4 AOC txoj kab hluav taws xob loj thiab 40G QSFP + mus rau LC 1: 8 AOC high-speed cable. Lawv feem ntau yog siv rau luv luv multi-channel cov ntaub ntawv kev sib txuas lus thiab kev sib txuas ntawm ob lub khoom siv, xws li kev sib dhos khib rau kev sib txuas sib txuas, khaws khoom, hubs, hloov chaw, routers, sib txuas ntawm cov servers, thiab lwm yam.

HTF' s cov khoom lag luam zoo tau lees tias, thiab cov khoom siv siv tau yog txawv txawv.
