Inkcazo:
I-JHA-Q28C20 yimodyuli ye-transceiver eyenzelwe i-20km izicelo zonxibelelwano olubonakalayo.Uyilo luhambelana ne-100GbASE-LR4 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-inputs (ch) ze-25.78 Gbps kwi-27.95Gbps idatha yombane kwi-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.
Ubude obuphakathi bemizila ye-4 yi-1296 nm, 1300 nm, 1305 nm kunye ne-1309 nm.Iqulethe i-duplex LC ikhonkco ye-optical interface kunye ne-38-pin ikhonkco yokudibanisa kombane.Ukunciphisa i-optical dispersion kwi-long-haul system, i-fiber ye-mode eyodwa (SMF) kufuneka isetyenziswe kule modyuli.
Imveliso 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 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-Q28C20 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.
