Imodyuli ye-40KM 40G QSFP+ Optical Transceiver
II-HUAQ40Eyimodyuli ye-transceiver eyenzelwe usetyenziso lonxibelelwano lwe-optical lwe-40Km. Uyilo luhambelana ne-40GBASE-ER4 yomgangatho we-IEEE P802.3ba. Le modyuli iguqula iitshaneli zokufaka ezi-4 (ch) zedatha yombane ye-10Gb/s zibe ziisignali zombane ze-4 CWDM, kwaye iziphindaphinde zibe yitshaneli enye yokudlulisela i-optical ye-40Gb/s. Ngokwahlukileyo koko, kwicala lomamkeli, imodyuli isusa ngokubonakalayo ii-multiplexes zokufaka ze-40Gb/s kwiisignali zombane ze-4 CWDM, kwaye iziguqulele kwidatha yombane ye-4 channel output.
Amaza obubanzi obuphakathi kwiitshaneli ezine zeCWDM yi-1271, 1291, 1311 kunye ne-1331 nm njengamalungu egridi yewavelength yeCWDM echazwe kwi-ITU-T G694.2. Iqulethe isixhumi se-LC esiphindwe kabini kwi-optical interface kunye nesixhumi se-38-pin kwi-electrical interface. Ukunciphisa ukusasazeka kwe-optical kwinkqubo ye-long-haul, kufuneka kusetyenziswe i-single-mode fiber (SMF) kule modyuli.
Le mveliso yenzelwe ukuba ibe ne-form factor, i-optical/electrical connection kunye ne-digital diagnostic interface ngokwe-QSFP Multi-Source Agreement (MSA). Yenzelwe ukuhlangabezana neemeko zokusebenza zangaphandle ezinzima kuquka ubushushu, ukufuma kunye nokuphazamiseka kwe-EMI.
Le modyuli isebenza ukusuka kumbane omnye we-+3.3V kwaye imiqondiso yolawulo yehlabathi ye-LVCMOS/LVTTL efana neModule Present, Reset, Interrupt kunye neLow Power Mode ziyafumaneka kunye neemodyuli. I-interface ye-serial ye-2-wire iyafumaneka ukuthumela nokufumana imiqondiso yolawulo enzima ngakumbi kunye nokufumana ulwazi lokuxilongwa kwedijithali. Iziteshi zomntu ngamnye zinokujongwa kwaye iziteshi ezingasetyenziswanga zinokuvalwa ukuze kube lula kakhulu uyilo.
Le mveliso iguqula idatha yokufaka umbane ye-4-channel 10Gb/s ibe yi-CWDM optical signals (light), nge-4-wavelength Distributed Feedback Laser (DFB) array eqhutywa yi-4-wavelength Distributed Feedback Laser (DFB). Ukukhanya kudibaniswa ngamalungu e-MUX njengedatha ye-40Gb/s, isasazeka kwi-transmitter module esuka kwi-SMF. I-receiver module yamkela i-40Gb/s CWDM optical signals input, kwaye iyisuse kwi-multiplexes kwiitshaneli ezine ze-10Gb/s ezine-wavelength eyahlukileyo. Ukukhanya ngakunye kwe-wavelength kuqokelelwa yi-discrete avalanche photodiode (APD), ize ikhutshwe njengedatha yombane emva kokuba ikhuliswe kuqala yi-TIA ize emva koko ikhutshwe yi-post amplifier.
II-HUAQ40EYenzelwe ukuba isebenzise i-form factor, i-optical/electrical connection kunye ne-digital diagnostic interface ngokwe-QSFP Multi-Source Agreement (MSA). Yenzelwe ukuhlangabezana neemeko zokusebenza zangaphandle ezinzima kuquka ubushushu, ukufuma kunye nokuphazamiseka kwe-EMI. Le modyuli inika ukusebenza okuphezulu kakhulu kunye nokuhlanganiswa kweempawu, okufikelelekayo nge-interface ye-serial yeengcingo ezimbini.
