Imodyuli ye-Tranceiver ye-QSFP+ ye-10KM engu-40G
IQI-SFP+ Amamojula e-transceiver aklanyelwe ukusetshenziswa kuma-Gigabit angu-40 ngomzuzwana phezu kwefayibha ye-multimode. Ahambisana ne-QSFP+ MSA kanye ne-IEEE 802.3ba 40GBASE-SR4. Ingxenye ye-optical transmitter ye-transceiver ifaka i-VCSEL (Vertical Cavity Surface Emitting Laser) eneziteshi ezine, i-buffer yokufaka yeziteshi ezine kanye nomshayeli we-laser, amabhlogo okulawula kanye ne-bias. Ingxenye ye-optical receiver ye-transceiver ifaka i-photodiode ye-PIN yeziteshi ezine, i-TIA yeziteshi ezine, i-buffer yokuphuma yeziteshi ezine, amabhlogo okulawula.

Imodyuli ye-Transceiver ye-QSFP+ ye-40KM engu-40G
II-HUAQ40Eiyimoduli ye-transceiver eyenzelwe izinhlelo zokusebenza zokuxhumana kwe-optical ezingama-40Km. Idizayini ihambisana ne-40GBASE-ER4 ye-IEEE P802.3ba standard. Imoduli iguqula iziteshi zokufaka ezine (ch) zedatha kagesi ye-10Gb/s zibe yizibonakaliso ze-optical ze-4 CWDM, futhi iziphindaphinde zibe yisiteshi esisodwa sokudlulisa kwe-optical kwe-40Gb/s. Ngokuphambene nalokho, ohlangothini lomamukeli, imoduli isusa ama-multiplex ngokubonakalayo okokufaka kwe-40Gb/s kube yizibonakaliso zeziteshi ze-4 CWDM, bese iziguqula zibe idatha kagesi yokukhipha iziteshi ezine.
Ama-wavelength aphakathi eziteshi ezine ze-CWDM angama-1271, 1291, 1311 kanye no-1331 nm njengamalungu egridi ye-wavelength ye-CWDM echazwe ku-ITU-T G694.2. Iqukethe isixhumi se-LC esiphindwe kabili se-optical interface kanye nesixhumi esingu-38-pin se-electrical interface. Ukuze kuncishiswe ukusabalala kwe-optical ohlelweni lwe-long-haul, i-fiber yemodi eyodwa (i-SMF) kufanele isetshenziswe kule module.
Lo mkhiqizo wenzelwe i-form factor, uxhumano lwe-optical/electric kanye ne-digital diagnostic interface ngokwe-QSFP Multi-Source Agreement (MSA). Wenzelwe ukuhlangabezana nezimo zokusebenza zangaphandle ezinzima kakhulu okuhlanganisa izinga lokushisa, umswakama kanye nokuphazamiseka kwe-EMI.
Imojuli isebenza kusukela ekuhlinzekweni kwamandla okukodwa kwe-+3.3V kanye nezimpawu zokulawula zomhlaba wonke ze-LVCMOS/LVTTL njengeModule Present, Reset, Interrupt kanye ne-Low Power Mode ziyatholakala namamojula. I-interface ye-serial enezintambo ezimbili iyatholakala ukuthumela nokwamukela izimpawu zokulawula eziyinkimbinkimbi kakhulu kanye nokuthola ulwazi lokuxilonga lwedijithali. Iziteshi ngazinye zingaxazululwa futhi iziteshi ezingasetshenziswanga zingavalwa ukuze kube nokuguquguquka okukhulu komklamo.
Lo mkhiqizo uguqula idatha yokufaka kagesi yeziteshi ezine engu-10Gb/s ibe yizimpawu zokukhanya ze-CWDM (ukukhanya), nge-4-wavelength Distributed Feedback Laser (DFB) array eqhutshwa ngamagagasi amane. Ukukhanya kuhlanganiswa yizingxenye ze-MUX njengedatha engu-40Gb/s, kusakazeke kumojuli wokudlulisa kusuka ku-SMF. Imojuli yokwamukela yamukela ukufakwa kwezimpawu zokukhanya ze-CWDM ze-40Gb/s, bese ikususa ama-multiplex ibe yiziteshi ezine ze-10Gb/s ezihlukene ngamagagasi. Ukukhanya ngakunye kwamagagasi kuqoqwa yi-photodiode ye-avalanche (APD) ehlukanisiwe, bese kukhishwa njengedatha kagesi ngemva kokukhuliswa kuqala yi-TIA bese kuba yi-post amplifier.
II-HUAQ40Eiklanyelwe nge-form factor, uxhumano lwe-optical/electric kanye ne-digital diagnostic interface ngokwe-QSFP Multi-Source Agreement (MSA). Iklanyelwe ukuhlangabezana nezimo zokusebenza zangaphandle ezinzima kakhulu okuhlanganisa izinga lokushisa, umswakama kanye nokuphazamiseka kwe-EMI. Imojula inikeza ukusebenza okuphezulu kakhulu kanye nokuhlanganiswa kwezici, okufinyeleleka nge-interface ye-serial enezintambo ezimbili.
