Uyilo luhambelana ne-100GbASE-SR4 ye-IEEE 802.3-2012 Igatya le-88 eliqhelekileyo le-IEEE 802.3bm CAUI-4 chip kwimodyuli yomgangatho wombane we-ITU-T G.959.1-2012-02 umgangatho . Imodyuli iguqula iziteshi ze-4 ze-input (ch) ze-25.78Gbps kwi-27.95Gbps idatha yombane kwii-4 imizila yeempawu ze-optical, kwaye i-multiplexes ibe yitshaneli enye ye-100Gb / s yokuhanjiswa kwe-optical. Umva, kwicala lokufumana, imodyuli i-optically de-multiplexes i-100Gb / s igalelo kwiimpawu zemizila ye-4, kwaye iguqulela kwiindlela ze-4 zokuvelisa idatha yombane. Intambo yeribhoni yefiber optical ene-MPO/MTP isinxibelelanisi kwiplagi nganye yokugqibela kwi-module ye-QSFP28 yokwamkela. Ukuqhelaniswa nentambo yeribhoni “ifakwe isitshixo” kwaye izikhonkwane zesikhokelo zikhona ngaphakathi kwesixhobo semodyuli ukuqinisekisa ulungelelwaniso olufanelekileyo. Intambo ngokuqhelekileyo ayinayo i-twist (isitshixo ukuya kwisitshixo phezulu) ukuqinisekisa ukulungelelaniswa kweshaneli efanelekileyo. Uqhagamshelo lombane luphunyeziwe nangona i-z-pluggable 38-pin IPASS® isidibanisi. Imodyuli isebenza ukusuka kumbane omnye + 3.3V kunye ne-LVCMOS / LVTTL iimpawu zolawulo lwehlabathi jikelele ezifana neModyuli ekhoyo, ukusetha kwakhona, ukuphazamisa kunye neModi yamandla aphantsi akhoyo kunye neemodyuli. I-2-wire serial interface iyafumaneka ukuze ithumele kwaye ifumane imiqondiso yolawulo entsonkothileyo kunye nokufumana ulwazi lokuxilonga idijithali. Iitshaneli zomntu ngamnye zinokujongwa kwaye amajelo angasetyenziswanga angavalwa ukulungiselela ukuguquguquka okukhulu koyilo. I-JHA-Q28C01 yenzelwe ifom yefom, i-optical / electric connection kunye ne-digital diagnostic interface ngokwe-QSFP28 Multi-Source Agreement (MSA). Yenzelwe ukuhlangabezana nezona meko zinzima zokusebenza zangaphandle ezibandakanya ubushushu, ukufuma kunye nokuphazamiseka kwe-EMI. Imodyuli inikezela ngokusebenza okuphezulu kakhulu kunye nokudityaniswa kweempawu, zifikeleleke nge-interface ye-serial ye-wire-wire. • IiReyithingi eziBalulekileyo zoPhawu lweSimboli uMz.
