Idizayini ithobelana ne-100GbASE-SR4 ye-IEEE 802.3-2012 Isigaba somthetho 88 esijwayelekile se-IEEE 802.3bm CAUI-4 chip ukuze kumojulwe indinganiso kagesi ye-ITU-T G.959.1-2012-02 . I-module iguqula iziteshi ze-4 zokufaka (ch) ze-25.78Gbps ku-27.95Gbps idatha kagesi ku-4 imizila yezimpawu ze-optical, futhi iphindaphinde ibe isiteshi esisodwa se-100Gb / s yokudlulisa optical. Ngokuhlehlayo, ohlangothini lomamukeli, imojula i-optically de-multiplexes okokufaka kwe-100Gb/s ibe amasignali emizila emi-4, futhi iwaguqulele emigwaqweni emi-4 ekhipha idatha kagesi. Intambo yeribhoni ye-fiber optical enesixhumi se-MPO/MTP ekugcineni ngakunye ixhuma esakhiweni semojuli ye-QSFP28. Ukuma kwentambo yeribhoni “kunokhiye” futhi izikhonkwane zikamhlahlandlela zikhona ngaphakathi kwesitsha semojuli ukuze kuqinisekiswe ukuqondana okufanele. Ikhebuli ngokuvamile ayinakho ukusonteka (ukhiye ufika phezulu) ukuze kuqinisekiswe ukuqondisa kwesiteshi esifanele. Ukuxhumeka kukagesi kufinyelelwa nakuba isixhumi esingu-z-pluggable 38-pin IPASS®. 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-Q28C01 yakhelwe nge-form factor, uxhumano lwe-optical/electric kanye nesixhumi esibonakalayo sokuxilonga esidijithali ngokweSivumelwano se-QSFP28 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.
