Ib qho MPO breakout module cais cov fibers los ntawm ntau - fiber ntau MPO / MTP connector rau hauv ib qho chaw nres nkoj - feem ntau LC duplex - yog li txhua tus khub fiber ntau tuaj yeem txuas mus rau ib qho chaw sib cais lossis thaj chaw ua haujlwm. Nws yog ib qho passive cable tswj tivthaiv siv nyob rau hauv cov chaw zov me nyuam cov ntaub ntawv thiab cov txheej txheem cabling systems los npaj siab -qhov ceev fiber ntau txuas.
MPO breakout module vs cassette: Dab tsi yog qhov txawv?
Cov nqe lus sib tshooj nyob ntawm qhov chaw tsim khoom. Feem ntau, lub cassette yog lub cev vaj tsev nyob (ib chav tsev modular uas swb rau hauv lub vaj huam sib luag lossis chassis), thaum lub sijhawm tawg yog hais txog kev ua haujlwm ntawm kev hloov MPO fibers rau LC lossis SC chaw nres nkoj. Nyob rau hauv kev xyaum, ntau cassettes muaj ib tug breakout module sab hauv. Lub ntsiab lus tseem ceeb yog tias ob qho tib si yuav tsum sib phim qhov tseeb fiber ntau suav, polarity, thiab connector specifications rau koj daim ntawv thov.
MPO polarity cuam tshuam li cas rau LC breakout ports?
Polarity txiav txim siab seb cov fiber ntau nyob rau hauv MPO connector maps rau qhov chaw nres nkoj LC ntawm lub breakout module. Yog hais tias txoj kev polarity ntawm lub cev cable, module, thiab thaj cords tsis phim qhov kawg mus rau qhov kawg, Tx teeb liab los ntawm ib qho transceiver yuav tsis ncav cuag Rx chaw nres nkoj ntawm lwm qhov. Qhov tshwm sim yog qhov txuas uas zoo li lub cev sib txuas tab sis tsis dhau kev khiav tsheb. Ua raws li txoj kev polarity zoo ib yam rau TIA-568.3-E thoob plaws txhua qhov tiv thaiv qhov teeb meem no.
Kuv puas tuaj yeem siv MPO breakout module nrog 400G QSFP-DD transceivers?
Tau. 400G QSFP-DD transceivers xws li 400GBASE-DR4 siv MPO-12 txuas nrog 8 active fibers, tawg tawm mus rau 4 × 100G ntawm LC duplex. 400GBASE-SR8 siv MPO-16 txuas nrog 16 fibers, tawg tawm mus rau 8 × 50G. Lub module yuav tsum phim cov transceiver tshwj xeeb suav fiber ntau, connector hom, thiab polarity yuav tsum tau.
8-fiber vs 12-fiber MPO breakout: Kuv yuav xaiv qhov twg?
Xaiv raws li daim ntawv thov transceiver. 40GBASE-SR4 thiab 100GBASE-SR4 siv 8 active fibers (4 Tx + 4 Rx) thiab tawg mus rau 4 LC duplex ports. Lub 12-fiber breakout module muab 6 LC duplex ports thiab yog siv rau hauv cov qauv cabling tsim qhov twg tag nrho 12 fibers nqa ib tug duplex raws. Txheeb xyuas cov ntaub ntawv transceiver kom paub meej tias muaj pes tsawg fibers ua haujlwm.
Puas yog MPO breakout modules passive lossis active Cheebtsam?
MPO breakout modules yog tag nrho passive. Lawv tsis muaj hluav taws xob, tsis muaj hluav taws xob, thiab tsis muaj teeb liab ua. Lawv txoj haujlwm yog xa cov fibers ntawm ib hom ntawv txuas mus rau lwm qhov. Qhov no txhais tau tias lawv ntxiv ib qho me me ntawm qhov poob (feem ntau 0.3-0.7 dB ib khub niam txiv sib txuas) tab sis tsis xav tau lub zog, teeb tsa, lossis hloov kho firmware.
Puas yog MPO breakout modules xav tau cov hlua tshwj xeeb?
Covpatch kablawv tus kheej yog cov qauv LC duplex lossis SC hom. Txawm li cas los xij, txoj kev polarity txiav txim siab seb koj puas xav tau A-rau-B (tus qauv crossover) lossis A-rau-A (txoj cai-los ntawm) duplex patch cords ntawm txhua qhov kawg. Paub meej tias qhov no yog ib feem ntawm qhov kawg -rau-kawg txoj kev npaj polarity ua ntej xaj cords.
Yuav ua li cas MPO breakout ports yuav tsum tau sau nyob rau hauv ib tug data center khib?
Siv lub npe zoo sib xws uas txheeb xyuas cov khib nyiab, vaj huam sib luag, txoj haujlwm cassette, thiab chaw nres nkoj tus lej - piv txwv li, "R12-P1-C3-Port4." Hla-reference txhua qhov chaw nres nkoj rau lub cev cable nws ua haujlwm thiab lub transceiver ntawm qhov kawg. Khaws daim ntawv qhia chaw nres nkoj digital nrog rau cov ntawv sau lub cev kom daws teeb meem sai dua.
