Cov Txuas MTP: Base-8 vs. Base-12 vs. Base-24
Rau cov chaw tswj cov ntaub ntawv, siv cov txheej txheem fiber ntau uas tuaj yeem txhim kho kom tau qhov kev xav tau ceev hauv lub network yav tom ntej yog thawj qhov uas yuav tsum tau txiav txim siab, vim tias kev txhim kho network yuav siv ntau lub sijhawm thiab nyiaj txiag. Yog li nws yog qhov yuav tsum tau xa cov ntawv fiber ntau uas yooj yim kom hloov mus rau cov ntaub ntawv siab dua txij thaum pib. Rau qhov muaj qhov ntom ntom ntom MTP txuas, Base-8 vs. Base-12 vs. Base-24: uas ib qho tuaj yeem muab txoj kev yooj yim ntawm kev mus ncig rau cov ntaub ntawv network yav tom ntej?
Lub hauv paus-8 MTP txuas yog raws li Hom B txiv neej / pinned MTP pob tw hauv caj qaum. Lub hauv paus-8 MTP yog SR4 npaj, txhais tau tias kev sib txuas sab nraub qaum muaj tib lub fiber ntau suav li SR4 transceiver. Lub hauv paus-8 MTP txuas tso cai rau cov neeg siv khoom kom them ncaj qha rau SR4 transceivers tsis tas yuav hloov cov txuas txuas nrog cov roj carbon fiber ntau qhov sib txawv los yog pov tseg cov fiber ntau hauv caj qaum. Raws li SR4 transceivers yog cov kev xaiv zoo dua rau 40G, 100G cov ntaub ntawv cov ntaub ntawv thiab dhau mus, Base-8 system yog qhov muaj peev xwm tshaj plaws thiab tuaj yeem-pov thawj yav tom ntej caj qaum kev xaiv tam sim no muaj. Cov neeg siv khoom siv 10G cov ntaub ntawv tus nqi niaj hnub no tseem tuaj yeem siv Base-8 txoj kev paub tias kev hloov kho mus rau 40G lossis 100G yuav yooj yim dua thiab raug nqi ntau dua yav tom ntej. Daim duab hauv qab no yog 1 × 3 MTP hloov kho hlua hluav taws xob cable siv hauv 40G / 100G network nrog 100% kev siv fiber ntau.
Lub hauv paus-12 MTP txuas raws li Hom A poj niam / qhov tsis muaj qhov tso cia MTP lub cev hauv caj qaum. Base-12 MTP yog qee tus SR4 npaj, vim hais tias txawm hais tias SR4 yog 8 fiber ntau interface, Base-12 MTP txuas tseem tau nrog nws. Tsis zoo li Base-8 MTP system, Base-12 tsis siv tag nrho cov kab hauv lub pob txha caj qaum thaum thawb ncaj qha nrog SR4 transceivers, txawm li cas los xij ntau tus Base-12 MTP txuas tau tuaj yeem ua ke thiab tom qab ntawd hloov pauv kom tag nrho cov siv fiber ntau tseem tuaj yeem ua tiav. Cov. Coj peb 2 × 3 MTP hloov kho hlua hluav taws xob cable piv txwv, cov MTP hloov kho cable muaj ob lub 12-fiber MTP txuas rau ntawm ib kawg thiab peb 8-fiber MTP txuas rau lwm qhov kawg, uas siv tag nrho 12 fiber hauv ob lub pob rau kev siv nrog peb chaw nres nkoj raws.
Lub hauv paus-24 MTP txuas feem ntau siv rau 100G thaum uas tig mus sib txuas khiav ntawm SR10 transceivers. Feem ntau cov kev sib txuas no yog nruab nrab ntawm ob qho ntawm cov ntaub ntawv siab-tus nqi hloov khoom raws li qhov hloov pauv mus rau server. Base-24 kuj tseem tuaj yeem siv rau cov ntaub ntawv qis dua tus nqi qaum xws li 10G thiab 40G tab sis qhov no ib txwm tsuas yog nyob rau kis uas qhov chaw thiab nruab sijhawm yog cov tsav tsheb tseem ceeb.
Thawj zaug Kev nqis peev
Base-8 xav tau cov peev txheej siab dua li Base-12 lossis Base-24 qaum vim muaj ntau dua ntawm MTP cov khoom sib txuas uas nruab los ntawm hnub 1. Txawm li cas los xij, kev tshawb fawb qhia tau hais tias qhov nce ntawm cov ntaub ntawv ceev yuav nce rov qab ntawm kev nqis peev hauv ob peb xyoos. Tsis tas li ntawd, Base-8 muab cov kev tsim kho txuas tau zoo tshaj plaws rau SR4 lub ntsiab lus tias kev nqis peev los hloov Base-12 lossis Base-24 rau SR4 yuav yog qhov loj yog tias tsis zam kiag tom qab.
Kev Siv Fiber
Txawm hais tias Base-12 nraub qaum tseem yog qhov kev xaiv ntau tshaj plaws rau feem ntau cov ntaub ntawv chaw lag luam niaj hnub no, nws yuav tsum raug sau tseg tias tseem tsis muaj cov qauv kev hloov pauv siv tag nrho 12 tus xov tooj hauv lub hauv paus-12 txuas. Tsis tas li ntawd, feem ntau yuav cuam tshuam transceiver interface SR4 yav tom ntej siv tsuas yog 8 daim txiag. Nrog qhov no hauv siab, cov neeg siv khoom yuav tsum txiav txim siab qhov tseem ceeb seb puas yuav siv Base-12 hnub no thiab kev pheej hmoo tsis raug 33% ntawm cov pob txha caj qaum tag kis, lossis mus ncaj rau Base-8 paub tias nws yuav yog qhov zoo tshaj plaws peev rau yav tom ntej.
No. Cov Cables
Muab piv rau Base-8 lossis Base-12, Base-24 txo cov xov tooj ntawm txoj hlua hluav taws xob uas yuav tsum muaj hauv qhov txuas, thiab qee zaum qhov no tuaj yeem yog tus neeg tsav tsheb kom siv cov interface tshwj xeeb no nyob hauv caj qaum. Txawm li cas los xij, nws yuav tsum raug sau tseg tias kev siv Base-24 raws li kev xaiv thim rov qab yuav xav tau MTP kev hloov mus los lossis MTP hloov kho chaw kom nws tsim nyog rau 10G thiab 40G cov ntaub ntawv tus nqi.
Los ntawm dab tsi tau piav qhia saum toj no, peb tuaj yeem pom tias Base-8 MTP txuas, Base-12 MTP txuas thiab Base-24 MTP txuas muaj lawv tus kheej cons thiab prons. Lub hauv paus-8 MTP txwv tso cai rau cov neeg siv los tsim 10G txuas hnub no tab sis yooj yim yuav txhim kho mus rau 40G txuas tag kis siv 8 fiber ntau MTP txuas. Lub hauv paus-12 thiab Base-24 MTP cov cuab yeej tso cai rau cov neeg siv los tsim 10G txuas hnub no, uas tuaj yeem hloov kho kom yooj yim rau 40G / 100G txuas tag kis siv MTP hloov kho modules, MTP hloov hlua los yog dhia tawm, tab sis yuav ua rau 33% cov leeg fiber ntau. Cov Txuas MTP: Base-8 vs. Base-12 vs. Base-24: uas yog koj xaiv?
