1. QSFP fiber optic transceiver module yog dab tsi?

- Ua ntej, peb yuav tsum nkag siab, SFP fiber optic transceiver module yog dab tsi? Lub SFP fiber optic transceiver module (lub npe tag nrho: Small Form-factor Pluggable), hais txog cov khoom siv me me, modular, hot-swappable network interface devices (transceivers) uas haum rau hauv cov chaw nres nkoj ntawm cov keyboards, routers, thiab servers, tso cai rau cov khoom siv network txuas ntawm ntau yam xov xwm xws li fiber optic lossis tooj liab cables rau ntau yam kev siv, los ntawm Gigabit Ethernet mus rau Fibre Channel.

- Lub QSFP (Quad Small Form-factor Pluggable) fiber optic transceiver module yog ib qho nrov transceiver form factor rau kev sib txuas lus ceev ceev, siv rau kev sib txuas lus ceev ceev hauv cov chaw khaws ntaub ntawv, txhawb nqa cov nqi los ntawm 10G txog 400G+ los ntawm kev siv plaub txoj kab sib luag, ua rau muaj bandwidth ntau dua li tus qauv SFPs hauv qhov loj me me. Cov kev hloov pauv tseem ceeb suav nrog QSFP+, QSFP28, QSFP56, thiab QSFP-DD, txhua tus txhawb nqa qhov ceev sib txawv (40G, 100G, 200G, 400G) los ntawm kev nce cov nqi ntaub ntawv ib txoj kab (10G, 25G, 50G, 100G) thiab siv cov tooj liab lossis fiber optic kev sib txuas.

2. QSFP ua haujlwm li cas?

- Cov QSFP fiber optic transceiver modules ntsaws rau hauv cov khoom siv network, hloov cov teeb liab hluav taws xob mus rau cov teeb liab optical lossis tooj liab rau kev xa cov ntaub ntawv ceev ceev, ua lub hauv paus tseem ceeb rau kev tsim kho network.

- Cov chaw nres nkoj QSFP ntawm cov keyboards txhawb nqa ntau hom xov xwm:

+ DAC (Direct Attach Copper): Pheej yig tshaj plaws rau kev sib txuas server-to-switch luv luv (feem ntau <7m).
+ AOC (Active Optical Cable): Siv cov fiber rau qhov deb ntev dua li tooj liab tab sis nrog cov khoom sib txuas ruaj khov ntawm ob qho kawg.
+ Cov Modules Optical: Cov transceivers uas ntsaws tau (xws li SR4, LR4, lossis BiDi) uas txuas rau cov cabling fiber optic txheem.
