MTP Links: Base-8 vs. Base-12 thiab Base-24
Rau cov neeg siv cov ntaub ntawv, muab lub tshuab fais fab uas tau yooj yim tuaj yeem hloov kho mus rau yav tom ntej kom ceev ceev yog thawj qhov uas yuav tsum tau xav, vim hais tias network reconfiguration yuav siv ntau lub sij hawm thiab nyiaj. Yog li ntawd, nws yog ib qhov tseem ceeb uas yuav tsum tau xa ib lub tshuab fiber ntau uas yog yooj yim los mus hloov cov ntaub ntawv ntau dua los ntawm qhov pib. Rau qhov siab ceev MTP txuas, Base-8 thiab Base-12 thiab Base-24: uas ib tus muaj peev xwm muab txoj kev yooj yim dua migration rau yav tom ntej network cov ntaub ntawv?
Base-8 MTP txuas raws li Hom B txiv neej / pinned MTP pob tw nyob rau hauv lub caj dab. Base-8 MTP yog SR4 npaj, txhais tau hais tias lub caj qaum connectivity muaj tib lub cim suav raws li tus SR4 transceiver. Base-8 MTP links pub cov neeg tuaj yeem xa ncaj nraim mus rau SR4 transceivers tsis hloov nrog cov khoom sib txuas nrog ntau hom phom los yog khib nyiab tshaj hauv cov caj qaum. Raws li SR4 cov khoom sib tw yog cov kev xaiv dua rau 40G, 100G cov nqi ntaub ntawv thiab dhau los, qhov System Base 8 yog qhov teeb meem feem ntau ntawm cov pob luj thiab yav tom ntej. Cov neeg tuaj yeem tso 10G cov nqi ntaub ntawv hnub no tseem tuaj yeem xa qhov Base-8 qhov kev paub txog tias kev hloov dua tshiab rau 40G los yog 100G yuav ntau dua thiab nqi zoo rau yav tom ntej. Cov duab hauv qab no yog 1 × 3 MTP kab xev kab xo siv hauv 40G / 100G network nrog 100% fiber ntau siv.
Base-12 MTP link yog nyob ntawm Hom A Cov poj niam / tsis muaj pob MTP pob txav nyob rau hauv lub caj pas. Base-12 MTP yog ib feem SR4 npaj, vim hais tias txawm tias SR4 yog 8 qhov kev sib txuas ntawm fiber ntau, qhov Base Base-12 MTP connector tseem nyob nrog nws. Tsis zoo li qhov Base-8 MTP system, Base-12 tsis siv tag nrho cov fibers hauv lub pob txawb thaum uas nrog cov SR4 hloov dua siab tshiab, tiam sis ntau qhov Base-12 MTP connectors tuaj yeem ua ke thiab tom qab ntawd ces hloov dua siab tshiab kom tag nrho cov roj siv tau tseem ua tiav . Coj peb 2 × 3 MTP kab xev kab xev rau piv txwv, cov kab no hloov MTP muaj ob tug 12-fiber ntau MTP connectors rau ib kawg thiab peb 8-fiber ntau MTP connectors rau lwm kawg, uas siv tag nrho 12 fibers hauv ob qho kev siv rau peb chaw nres nkoj raws.
Base-24 MTP txuas yog feem ntau tau npaj rau 100G thaum uas tig mus sib txuas khiav dua SR10 hloov tau. Feem ntau cov kev sib txuas yog nyob nruab nrab ntawm ob qhov kev hloov siab hloov cov ntaub ntawv uas tsis tau hloov mus rau cov neeg rau zaub mov. Base-24 kuj tseem siv tau rau cov ntaub ntawv qis dua qaum kev txuas xws li 10G thiab 40G tiam sis qhov no feem ntau tsuas yog thaum qhov chaw thiab nruab ib lub sij hawm yog tus yuam sij tsav.
Pib ua lag luam
Base-8 yuav tsum tau muaj peev xwm ua ntej nce siab tshaj qhov Base-12 lossis Base-24 backbones vim tias muaj ntau tus MTP cov khoom sib txuas ntawm nruab hnub 1. Txawm li cas los xij, kev tshawb fawb pom tau tias qhov nce ntawm cov nqi ceev ceev ntawm peev li ntawm ob peb xyoos. Txuas ntxiv, Base-8 muab qhov sib txuas sib txuas tshaj plaws rau SR4 lub ntsiab lus tias cov peev nyiaj hloov los hloov Base-12 los yog Base-24 rau SR4 yuav yog qhov tsis tas yuav zam dhau lawm.
Siv Cov Khoom Siv
Txawm hais tias Base-12 pob qaum teb tseem yog qhov tseem xaiv rau feem ntau cov chaw nruab nrab cov neeg teb xov tooj niaj hnub no, nws yuav tsum raug sau tseg tias tseem tsis muaj kev hloov kev hloov kev siv tag nrho 12 fibers hauv ib qhov Base-12 connector. Txuas ntxiv, qhov feem ntau yuav tau transceiver interface SR4 yav tom ntej siv tsuas yog 8 fibers. Nrog rau qhov no, cov neeg muas zaub yuav tsum tau txiav txim siab tseem ceeb heev los mus rau qhov Chaw Tshawb Feeb-12 hnub no thiab yuav raug quab yuam 33% ntawm pob qij txhav tag kis, lossis mus ncaj nraim rau Base-8 kom paub tias nws yuav yog qhov zoo tshaj plaws rau yav tom ntej.
Tsis muaj
Piv rau Base-8 lossis Base-12, Base-24, txo cov hlua uas yuav tsum muaj nyob hauv qhov txuas, thiab qee zaus qhov no yog ib tus neeg tsav tsheb rau kev siv qhov kev sib tshuam no hauv kev txheeb ze. Txawm li cas los xij, nws yuav tsum raug sau tseg tias kev faib tawm Base-24 raws li kev xaiv qaum xaiv yuav tau hloov MTP hloov modules los yog MTP kev hloov xoob los ua kom haum rau 10G thiab 40G cov ntaub ntawv.
Los ntawm dab tsi tau piav saum toj no, peb tuaj yeem pom tias qhov Base-8 MTP link, Base-12 MTP link thiab Base-24 MTP txuas tau lawv tus kheej cov kev xav thiab lus. Base-8 MTP trunks pub cov neeg siv los tsim kom muaj 10G tiam hnub no, tiam sis yooj yim muab kho tau kom txog 40G rau tag kis siv 8 phom MTP connectivity. Base-12 thiab Base-24 MTP cov cuab yeej pub rau cov neeg siv tsim 10G cov tswv yim hnub no, uas tuaj yeem muab kho tau kom txog 40G / 100G kev siv yav sawv ntxov siv MTP conversion modules, MTP hloov ua xev los yog dhia, tab sis yuav ua rau 33% fiber ntau dua. MTP Links: Base-8 vs. Base-12 vs. Base-24: Koj yog tus xaiv?
