CFP series pib los ntawm CFP, mus rau CFP2, tom qab ntawd mus rau CFP4, thiab thaum kawg rau CFP8, uas tseem yog qhov ntev-tsim daim ntawv-txheej. Muab piv rau QSFP series, CFP series zoo li tsis tshua muaj neeg nyiam, rau qhov pom tseeb - qhov loj me thiab kev siv lub zog loj. Thawj ob lub tuam txhab uas tau txhawb kev tsim kho CFP MSA (Finisar thiab Oclaro) kuj tau yuav, thiab peb zoo li xav tias qhov kawg ntawm CFP.
Cia' s siv sijhawm saib CFP8. CFP8 qhov tseem ceeb txog kev kho vajtse tau tso tawm los ntawm CFP MSA rau Lub Peb Hlis 17, 2017, nyob rau tib lub sijhawm nrog 2.0 version ntawm QSFP-DD MSA raug tso tawm. Muab piv rau ob daim ntawv foos, peb zoo li tau pom txog qhov poob ntawm CFP8.
Loj -Qhov loj ntawm CFP8 (41.5mm * 107.5mm * 9.5mm) yog qhov loj dua QSFP-DD, thiab lub ntim ntau dua peb zaug ntawm QSFP-DD, txawm tias ntau dua 30% loj dua li ntawm OSFP. Txij li CFP series optical module tau muab tso rau cov ntawv thov kev sib txuas lus, thiab qhov chaw nres nkoj ntom ntom tsis muaj qhov siab nyob hauv cov ntaub ntawv chaw, yog li qhov loj tau siv tau. Txawm li cas los xij, nrog kev nce qib ntawm kev siv thev naus laus zis, QSFP series optical modules tseem pib kom tsim nyog rau kev siv xov tooj sib txuas lus, thiab lub zog noj ntawm QSFP series optical modules muaj qis dua qhov ntawm CFP series optical modules. Yog li no, txoj haujlwm tseem ceeb ntawm CFP series kho qhov muag cov qauv siv hauv kev sib txuas xov tooj yog nyob ntawm lub luag haujlwm.
Thermal Muaj Peev Xwm thiab Siv Hluav Taws Xob -Kev ua tau zoo ntawm thermal thiab lub zog ntawm CFP8 yog ntau dua QSFP-DD. Kev qhia txog kev ua haujlwm thermal thiab lub zog siv tau qhia hauv QSFP-DD dhau los. OSFP, thiab qhov tseeb zoo ib yam.
Rov Qab Tau Tau -Tsis muaj ib qho hais rov qab ntawm qhov rov qab nkag tau hauv qhov kev qhia kho vajtse ntawm CFP8 (qhov tseeb, tag nrho CFP koob tsis zoo li rov qab tau tshaj). Rau CFP thiab CFP2 series optical modules, CFP mus rau QSFP28 adapter thiab CFP2 rau QSFP28 adapter tau muaj lub sijhawm ntev, uas qhia tau tias qee cov neeg siv tau hloov mus rau QSFP28 optical modules.
Bandwidth -Bandwidth ntau tshaj ntawm CFP8 thiab QSFP-DD yog 400Gb / s, tab sis CFP8 tsuas yog txhawb nqa 400Gb / s (16x25G lossis 8x50G), thaum QSFP-DD txhawb nqa 200Gb / s (8x25G) thiab 400Gb / s (8x50G).
Hauv txoj kev xaus, QSFP-DD zoo li yog qhov kev xaiv zoo dua li CFP8, tsis hais qhov twg los xij.
