A: Feem ntau, yog. Ntau QSFP28 cov chaw nres nkoj rov qab- sib xws thiab yuav lees txais 40G QSFP + optic, tab sis qhov no yog lub platform- nyob ntawm - lees paub nws hauv cov ntaub ntawv hloov pauv thiab kev sib raug zoo matrix es tsis yog xav.
Q: Puas yog QSFP tau tshaj SFP +?
A: Tsuas yog los ntawm kev tawg, tsis yog los ntawm kev ntxig ib qho mus rau lwm qhov. Ib qho 40G QSFP + lossis 100G QSFP28 chaw nres nkoj tuaj yeem tawg mus rau 4 × 10G SFP + lossis 4 × 25G SFP28 siv cov kab sib txuas kom raug, muab qhov hloov pauv thiab OS txhawb kev tawg hom.
Q: Dab tsi cable kuv xav tau rau QSFP SR4 module?
A: Ib qho MPO / MTP multimode pob tw lossis tawg (feem ntau 8 lossis 12 fibers ntawm OM3 / OM4), nrog qhov tseeb polarity. SR4 yog tib yam optics, yog li LC duplex thaj qaum yuav tsis ua haujlwm.
Q: Puas yog tag nrho QSFP modules siv MPO connectors?
A: Tsis yog. Parallel luv- ncav cuag QSFP optics siv MPO / MTP, tab sis WDM hom xws li LR4 lossis CWDM4 siv LC duplex los ntawm multiplexing wavelengths tshaj ob fibers.
Q: Qhov txawv ntawm QSFP + thiab QSFP28 yog dab tsi?
A: QSFP + yog 40G tshaj 4 × 10G; QSFP28 yog 100G tshaj 4 × 25G. Lawv tuaj yeem zoo sib xws tab sis ua haujlwm sib txawv ceev tiam.
Q: Kuv puas yuav tsum siv DAC, AOC, lossis optical transceivers?
A: Siv DAC luv luv, nqi - thiab fais fab -rack txuas; AOC rau lub teeb yuag luv luv - mus rau - nruab nrab cov ntaub ntawv chaw khiav; thiab optical transceivers nrog thaj cords thaum koj xav tau kev hloov pauv tau yooj yim, ncav cuag ntev dua, kev teeb tsa cabling, lossis kev saib xyuas yooj yim dua.
Q: Qhov twg zoo dua rau cov chaw zov me nyuam, SFP lossis QSFP?
A: Ob leeg. SFP28 yog ib txwm muaj rau 25G neeg rau zaub mov-ntseeg txuas, thaum QSFP28 lossis QSFP-DD ua haujlwm siab- nrawm nrawm, txha nraub qaum, thiab cov tub ntxhais. Kev tsim qauv sib npaug siv ob qho tib si.

QSFP thiab SFP daws teeb meem sib txawv. SFP yog qhov zoo tshaj plaws rau kev hloov pauv, kev cog lus, ib leeg - txoj kab kev sib txuas ntawm 1G, 10G, lossis 25G - kev nkag mus rau kev lag luam, kev lag luam Ethernet, kev sib txuas ntawm cov neeg rau zaub mov, thiab kev hloov kho qub qub. QSFP yog qhov zoo tshaj plaws rau kev sib sau ua ke bandwidth ntau dua, muaj txiaj ntsig uplinks, breakout, thiab ntom hloov - qaum- cov ntaub ntawv tseem ceeb, txheej txheej sib sau, siab - routers ceev, thiab AI thiab huab infrastructure.
Ua ntej koj txiav txim siab, ua hauj lwm hauv daim ntawv txheeb xyuas: tus tswv tsev tawb, yuav tsum tau ceev, nyob deb, hom fiber ntau, connector, neeg muag khoom compatibility, breakout kev them nyiaj yug, thiab per -chaw nres nkoj hwj chim. Qhov zoo tshaj plaws transceiver tsis yog qhov ceev tshaj plaws; nws yog ib qho uas haum rau koj qhov architecture, koj cov nroj tsuag fiber ntau, thiab koj txoj kev npaj kho dua tshiab.
