Tsis muaj Kev Hloov Pauv Hloov Pauv Hloov Pauv Hloov Pauv Hloov Pauv Hloov Pauv Hloov Pauv: Qhov Kev Siv Rau 40G Qhov Teem Ua Dabtsi?
Thaum sib tham txog 40G cabling, MPO cable yog qhov kev xaiv tshaj plaws rau cov neeg saib xyuas cov ntaub ntawv siv. Hnub no, kuv xav tham txog peb hom MTP cabling xaiv rau 40G parallel connectivity. Thawj hom yog los faib MPO 12 cable thiab tsis quav ntsej cov tsis siv plaub daim txiag ntsej muag. Thiab lwm ob hom yog siv cov khoom siv los yog hloov pauv hloov los hloov ob tug 12-fibre txuas mus rau peb lub 8-fibre links. Li ntawd, peb cabling xaiv-tsis muaj conversion thiab modem conversion thiab seev cev conversion: uas yuav siv rau 40G parallel tov?
Tsis muaj kev hloov dua siab tshiab, 12-fiber ntau ntawm MTP pob tw cab cab deployed hauv tag nrho 40G connectivity. Tab sis nyob rau hauv qhov teeb meem no, 33% fiber tsis siv. Thiab yuav muaj nqi ntxiv nrog rau kev yuav khoom ntxiv fiber. Tsis tas li ntawd, tag nrho lub cev muaj cov tsis siv fibers.
Daim duab 1: tsis muaj kev hloov dua siab tshiab, qhov txuas tag nrho siv rau hauv paus-12 MTP / MPO cable
Thaum uas siv cov khoom siv hloov dua siab tshiab, nws tuaj yeem hloov cov fibers uas tsis siv los rau hauv cov khoom siv fiber ntau. Rau txhua ob tug 12-fiber ntau MTP connectors nyob rau hauv kab rov qab cable, koj muaj peev xwm tsim peb 8-fiber ntau kev txuas. Txawm hais tias yuav muaj nqi ntxiv rau MTP txuas txuas ntxiv, nws tuaj yeem tau offset los ntawm cov nqi nyiaj los ntawm 100% fiber siv nyob rau hauv lub cabulated teeb. Thaum reusing uas twb muaj lawm deployed MTP cabling, tus nqi zoo yuav tsum tau yog siv cov module conversion siv tag nrho yav tas los deployed fiber ntau, thiab koj tua tus nqi uas yuav tsum tau xa ntxiv cabling.
Daim Duab 2: siv cov qauv siv los hloov ua ob txoj hlua 12-fibre mus rau peb qhov sib txuas ua ke 8
Lub scenario no siv cov qauv MTP cov qauv thiab 2 × 3 MTP hloov peg siab. Nws tsis ntxiv kev txuas mus rau qhov txuas thiab puv siv hluav taws xob ua tiav. Txawm hais tias nws zoo li txaus nyiam, nws muaj teeb meem cab cab. Piv txwv li, yog tias koj tsuas xav tau ob qhov txuas 40G rau cov cuab yeej, koj yuav ua li cas nrog rau peb qhov txuas 8-fiber ntau MTP? Los yog ua li cas yog tias cov chaw nres nkoj 40G muaj nyob rau hauv ntau lub chassis tuaj los yog cov yias sib txawv kiag li hauv chassis? Cov txiaj ntsig yuav yog ntev rooj sib txoos, uas yuav nyuaj rau kev tswj nyob rau hauv ib txoj kev sib koom. Vim li no, hom tshuaj daws no yuav tsum yog qhov tsawg kawg yog ntshaw thiab yog li qhov tsawg tshaj plaws tau npaj txoj kev.
Xam phaj 3: siv cov hlua khi tawm los hloov ob tug 12-fib fab txuas mus rau peb qhov sib txuas ua ke 8
Rau peb hom kev daws teeb meem, "No Conversion" tov, siv cov tsoos 12-fiber ntau MTP txuas thiab ignoring fibers tsis siv, muaj qhov kom zoo dua simplicity thiab qhov sib txuas qis dua. Thiab raws li nws tsis siv 33% ntawm cov khoom siv fiber ntau, nws mam li yuav tsum tau ntxiv cov kab tsheb ciav hlau.
"Conversion Module" solution, hloov ob lub 12-fiber txuas mus rau peb lub 8-fiber txuas mus los ntawm ib lub vaj huam sib luag hloov khoom siv, siv tag nrho cov pob txha caj qaum thiab tsim kom muaj lub vaj huam sib luag, cov khoom txaws tau nrog cov khoom tawm hauv tsev. Tab sis nws yuav ua rau cov nqi txuas ntxiv thiab qhov kev cuam tshuam nrog kev hloov twj paj nruag.
Cov "Conversion Harness" solution, hloov ob tug 12-fiber ntau txuas rau peb 8-fiber ntau kev sib txuas los ntawm kev hloov pauv pawg thiab cov qauv MTP thaj qauv, siv tag nrho cov pob txha caj qaum nrog kev txuas ntxiv. Tab sis nws yuav tsim teeb meem kev sib tw nrog dangling connectors thiab tsis-optimized-ntev thaj cords uas yuav tsum tau customization.
Feem ntau, qhov kev siv ntawm kev hloov kho module module yog pom zoo, tshwj xeeb tshaj yog tias koj siv cov kab MTP yav tas los siv. Module Conversion module pub rau 100% fiber siv thaum tswj txhua qhov chaw nres nkoj mus rau qhov chaw nres nkoj patching. Thiab yog tias koj txhim kho qhov tshiab cabling, ces koj tuaj yeem xav txog qhov tsis muaj kev hloov dua siab tshiab, piv txwv tias cov cable raceway tsis yog kev txhawj xeeb. Kev hloov harness cov kauj ntseg yog feem ntau tsuas yog siv rau tej daim ntaub ntawv siv, xws li ntawm ToR hloov, qhov chaw 40G yog nyob rau hauv ib qho chaw ze thiab patching ntawm cov ceg hauv lub chassis hloov tsis tau.
Los ntawm dab tsi tau piav saum toj no, koj puas tau to taub zoo dua qhov peb hom ntawm 40G cabling daws? Txhua yam muaj nyias qhov zoo thiab qhov tsis zoo. Rau cov kev xaiv ntawm peb xaiv-tsis hloov dua siab tshiab thiab hloov conversion module thiab hloov ua pawg ntseeg: uas yog koj qhov kev xaiv rau 40G kev daws teeb meem?
