Idizayini ithobelana ne-40GBASE-ER4 yezinga le-IEEE P802.3ba. I-module iguqula iziteshi ze-4 zokufakwayo (ch) zedatha kagesi ye-10Gb / s kumasignali we-4 CWDM optical, futhi iphindaphinda ibe isiteshi esisodwa se-40Gb / s yokudlulisa optical. Ngokuhlehlayo, ohlangothini lomamukeli, imojula i-optically de-multiplexes okokufaka kwe-40Gb/s kumasignali amashaneli angu-4 CWDM, futhi iwaguqulela kudatha kagesi ephumayo yesiteshi esingu-4. Amaza amaphakathi eziteshi ezi-4 ze-CWDM angu-1271, 1291, 1311 kanye no-1331 nm njengamalungu egridi ye-wavelength ye-CWDM echazwe ku-ITU-T G694.2. Iqukethe isixhumi se-LC esiyi-duplex yesixhumi esibonakalayo esibonakalayo nesixhumi samaphini angama-38 esixhumi esibonakalayo sikagesi. Ukuze kuncishiswe ukuhlakazeka kokubona ohlelweni lokudonsa isikhathi eside, i-fiber yemodi eyodwa (SMF) kufanele isetshenziswe kule mojula. Umkhiqizo uklanywe nge-form factor, uxhumano lwe-optical/electric kanye ne-digital diagnostic interface ngokuvumelana ne-QSFP Multi-Source Agreement (MSA). Iklanyelwe ukuhlangabezana nezimo zokusebenza zangaphandle ezinzima kakhulu ezihlanganisa izinga lokushisa, umswakama kanye nokuphazanyiswa kwe-EMI. Imojula isebenza kugesi owodwa we-+3.3V kanye namasiginali okulawula umhlaba wonke we-LVCMOS/LVTTL njengeModule Present, Setha Kabusha, Ukuphazamisa kanye Nemodi Yamandla Aphansi ayatholakala namamojula. I-serial interface enezintambo ezi-2 iyatholakala ukuze ithumele futhi yamukele amasiginali okulawula ayinkimbinkimbi kanye nokuthola ulwazi lokuxilonga lwedijithali. Iziteshi ngazinye zingasingathwa futhi iziteshi ezingasetshenzisiwe zingavalwa ukuze umklamo ube nezimo eziguquguqukayo. I-JHA-QC40 yakhelwe nge-form factor, uxhumano lwe-optical/electric kanye nesixhumi esibonakalayo sokuxilonga sedijithali ngokweSivumelwano se-QSFP Multi-Source Agreement (MSA). Iklanyelwe ukuhlangabezana nezimo zokusebenza zangaphandle ezinzima kakhulu ezihlanganisa izinga lokushisa, umswakama kanye nokuphazanyiswa kwe-EMI. Imojula inikeza ukusebenza okuphezulu kakhulu nokuhlanganiswa kwesici, okufinyeleleka nge-serial interface enezintambo ezimbili. • Absolute Maximum Izilinganiso Ipharamitha Symbol Min.
