He pai te hoahoa ki te 100GbASE-SR4 o te IEEE 802.3-2012 Clause 88 paerewa IEEE 802.3bm CAUI-4 maramara ki te paerewa hiko ITU-T G.959.1-2012-02. Ka huri te kōwae i nga hongere whakauru e 4 (ch) o te 25.78Gbps ki te 27.95Gbps nga raraunga hiko ki nga huarahi 4 tohu tohu, ka whakatiki ki roto i te hongere kotahi mo te 100Gb/s tuku whatu. I tua atu, i te taha o te kaikawe, ka whakakorehia e te kōwae te whakaurunga 100Gb/s ki roto i nga tohu ara e 4, ka huri ki te 4 nga ara whakaputa raraunga hiko. He taura riipene muka whatu me te hono MPO/MTP i ia pito ka kuhu ki roto i te ipu QSFP28. Ko te takotoranga o te taura rīpene he “pātuhi” me ngā titi arataki kei roto i te ipu o te kōwae kia tika ai te tīaroaro. I te nuinga o te wa karekau he korikori o te taura (ki runga ki te ki runga) kia tika ai te hongere ki te tiaroaro. Ka tutuki te hononga hiko ahakoa he hononga hono IPASS® 38-pin. Ka mahi te kōwae mai i te + 3.3V hiko hiko kotahi me nga tohu mana whakahaere o te ao LVCMOS/LVTTL penei i te Module Present, Reset, Interrupt and Low Power Mode e waatea ana me nga waahanga. He atanga rangatū 2-waea e waatea ana ki te tuku me te whiwhi tohu whakahaere uaua ake me te whiwhi korero whakamaarama mamati. Ka taea te whakatika i nga hongere takitahi, ka taea te tutakina nga hongere kaore i whakamahia mo te ngawari o te hoahoa. Ko te JHA-Q28C01 i hangaia me te ahua o te ahua, te hononga whatu/hiko me te atanga tātaritanga mamati e ai ki te QSFP28 Multi-Source Agreement (MSA). Kua hoahoatia kia tutuki i nga tikanga whakahaere o waho rawa atu, tae atu ki te mahana, te makuku me te wawaotanga EMI. Ko te kōwae e whakarato ana i nga mahi tino tiketike me te whakaurutanga o nga ahuatanga, ka taea ma te atanga rangatū waea-rua. • Tohu Tawhā Whakatauranga Morahi Moni. Max angamaheni.
