Tus qauv tsim yog ua raws li 100GbASE-SR4 ntawm IEEE 802.3-2012 Clause 88 tus qauv IEEE 802.3bm CAUI-4 nti rau module hluav taws xob tus qauv ITU-T G.959.1-2012-02 tus qauv. Lub module hloov 4 inputs channels (ch) ntawm 25.78Gbps rau 27.95Gbps cov ntaub ntawv hluav taws xob rau 4 kab kev kho qhov muag teeb liab, thiab multiplexes rau hauv ib qho channel rau 100Gb / s optical kis tau tus mob. Reversely, nyob rau sab receiver, lub module optically de-multiplexes ib tug 100Gb / s input rau 4 txoj kab kev teeb liab, thiab converts lawv mus rau 4 kab khiav tawm cov ntaub ntawv hluav taws xob. Ib qho fiber ntau optical ribbon cable nrog MPO / MTP connector ntawm txhua qhov kawg ntsaws rau hauv QSFP28 module receptacle. Txoj kev taw qhia ntawm lub ribbon cable yog "keyed" thiab cov lus qhia pins muaj nyob rau hauv lub module lub receptacle los xyuas kom meej kev sib raug zoo. Cov kab hluav taws xob feem ntau tsis muaj qhov sib tw (qhov tseem ceeb mus rau qhov tseem ceeb) kom paub meej cov channel zoo rau kev sib raug zoo. Kev sib txuas hluav taws xob tau ua tiav txawm tias z-pluggable 38-pin IPASS® connector. Lub module ua haujlwm los ntawm ib qho +3.3V fais fab mov thiab LVCMOS / LVTTL thoob ntiaj teb kev tswj cov cim xws li Module Tam Sim No, Pib dua, cuam tshuam thiab Tsawg Fais Fab Hom muaj nyob nrog cov modules. Lub 2-xaim serial interface muaj nyob rau xa thiab tau txais kev tswj cov teeb meem nyuaj thiab kom tau txais cov ntaub ntawv kuaj mob digital. Cov kab ke ntawm tus kheej tuaj yeem hais tau thiab cov channel tsis siv tau tuaj yeem raug kaw kom tsim tau qhov yooj yim tshaj plaws. JHA-Q28C01 yog tsim los nrog cov qauv tsim, kho qhov muag / hluav taws xob sib txuas thiab digital diagnostic interface raws li QSFP28 Multi-Source Agreement (MSA). Nws tau raug tsim los ua kom tau raws li qhov kev ua haujlwm hnyav tshaj plaws nrog rau qhov kub thiab txias, av noo thiab EMI cuam tshuam. Lub module muaj kev ua haujlwm siab heev thiab kev sib koom ua ke, siv tau los ntawm ob-xaim serial interface. • Tsis Txaus Siab Qhov Kev Ntsuas Parameter Cim Min. Hom Max.
