Imodyuli ye-QSFP epheleleyo ye-duplex ye-optical inika i-4 i-transmit ezimeleyo kunye nokufumana iziteshi, nganye iyakwazi ukusebenza kwe-10Gbps ye-bandwidth edibeneyo ye-40Gbps 300m kwi-OM3 Multimode Fiber (MMF) kunye ne-400m kwi-OM4 MMF. Intambo yeribhoni yefiber optical ene-MPO/MTP isinxibelelanisi kwiplagi nganye yokugqibela kwisakhelo semodyuli ye-QSFP. 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-QC01 yenzelwe ifom yefom, i-optical / electric connection kunye ne-digital diagnostic interface ngokwe-QSFP 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. l IiReyithingi ezona ziPhezulu zoPhando lweSimboli uMz.

I-2-wire serial interface ibonelela umsebenzisi ukuba aqhagamshelane nemodyuli. Ubume bememori buboniswa ngokuhamba. Indawo yememori icwangciswe ngezantsi, iphepha elinye, indawo yedilesi ye-128 bytes kunye namaphepha amaninzi esithuba sedilesi ephezulu. Esi sakhiwo sivumela ukufikelela kwangethuba kwiidilesi ezikwiphepha elisezantsi, elifana neFlegi yokuphazamisa kunye neeMonitors. Ixesha elincinci lokungena kwexesha elibalulekileyo, elifana nolwazi lwe-ID ye-serial kunye noseto lwe-threshold, luyafumaneka kunye nomsebenzi wokuKhetha iPhepha. Idilesi ye-interface esetyenzisiweyo yi-A0xh kwaye isetyenziselwa ubukhulu becala idatha ebaluleke kakhulu njengokuphatha ukuphazamiseka ukwenzela ukuba kufundwe ixesha elilodwa kuyo yonke idatha enxulumene nemeko yokuphazamiseka.
