40KM 40G QSFP + Imodyuli yeTransceiver ye-Optical
IHUAQ40Eyimodyuli ye-transceiver eyenzelwe i-40Km izicelo zonxibelelwano olubonakalayo.Uyilo luhambelana ne-40GBASE-ER4 yomgangatho we-IEEE P802.3ba.Imodyuli iguqula iziteshi ze-4 ze-inputs (ch) ze-10Gb / s idatha yombane kwiimpawu ze-4 ze-CWDM ze-optical, kwaye i-multiplexes ibe yindawo enye ye-40Gb / s yokuhanjiswa kwe-optical.Umva, kwicala lommkeli, imodyuli i-optically de-multiplexes i-40Gb / s igalelo kwiimpawu zeziteshi ze-CWDM ze-4, kwaye ziguqulela kwi-4 data yedatha yombane yombane.
Ubude obuphakathi bamatshaneli e-4 CWDM yi-1271, 1291, 1311 kunye ne-1331 nm njengamalungu egridi ye-CWDM ye-wavelength echazwe kwi-ITU-T G694.2.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-QSFP 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.
Le mveliso iguqula i-4-channel 10Gb / s idatha yokufakelwa kombane kwiimpawu ze-CWDM optical (ukukhanya), ngokuqhutywa kwe-4-wavelength Distributed Feedback Laser (DFB) uluhlu.Ukukhanya kudibaniswa ngamalungu e-MUX njengedatha ye-40Gb / s, isasaza ngaphandle kwemodyuli yokuhambisa kwi-SMF.Imodyuli yomamkeli yamkela i-40Gb / s CWDM ye-optical signal input, kwaye i-de-multiplexes ibe yi-4 iziteshi ze-10Gb / s ezinobude obuhlukeneyo.Isibane ngasinye sobude bobude buqokelelwa yi-avalanche photodiode (APD), kwaye emva koko ikhutshwe njengedatha yombane emva kokukhulisa kuqala nge-TIA kwaye emva koko nge-amplifier yeposi.
IHUAQ40Eyenzelwe ifom factor, uxhulumaniso lwe-optical / electric interface 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, kufikeleleke nge-interface ye-serial ye-wire-wire.
Iimbonakalo Iindlela ezi-4 zeCWDM ziyi-MUX/DEMUX Ukuya kuthi ga kwi-11.2Gbps kwi-bandwidth yetshaneli nganye I-Aggregate bandwidth ye> 40Gbps Isidibanisi se-LC eDuplex Ihambelana ne-40G Ethernet IEEE802.3ba kunye ne-40GBASE-ER4 Standard QSFP MSA iyahambelana Ukuya kuthi ga kwi-40km yosasazo Iyahambelana nexabiso ledatha ye-QDR/DDR Infiniband Eyodwa +3.3V unikezelo lwamandla olusebenzayo Eyakhelwe ngaphakathi imisebenzi yokuxilongwa kwedijithali Uluhlu lobushushu 0°Cto 70°C I-RoHS iyahambelana
