Whakaahuatanga:
Ko te JHA-Q28C20 he waahanga whakawhiti i hangaia mo te 20km nga tono whakawhitiwhiti whakaaro. He pai te hoahoa ki te 100GbASE-LR4 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 25.78 Gbps ki te 27.95Gbps nga raraunga hiko ki nga huarahi e 4 nga tohu whatu, me te whakatiki ki 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.
Ko nga roangaru o waenganui o nga ara e 4 ko 1296 nm, 1300 nm, 1305 nm me 1309 nm. Kei roto he hononga LC matarua mo te atanga whatu me te hono 38-pin mo te atanga hiko. Hei whakaiti i te marara whatu i roto i te punaha tere-roa, me tono te muka aratau-kotahi (SMF) ki tenei waahanga.
I hangaia te hua 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.
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.
I hangaia te JHA-Q28C20 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.

•Atanga Aroturuki Tataunga
Kei te waatea te mahi aroturuki tātaritanga mamati i runga i te QSFP28 LR4 katoa. Ko te atanga rangatū 2-waea e whakarato ana i te kaiwhakamahi ki te whakapā atu ki te kōwae. Ko te hanganga o te mahara ka whakaatuhia i te rere. Kua whakaritea te mokowā mahara ki te wharangi iti, kotahi te wharangi, te mokowā wāhitau 128 paita me te maha o nga wharangi mokowā wāhitau o runga. Ka taea e tenei hanganga te uru ki nga wahitau kei te wharangi o raro, penei i nga Kara Interrupt and Monitors. He iti ake te waa whakaurunga wa tino nui, penei i nga korero TT rangatū me nga tautuhinga paepae, e waatea ana me te mahi Tohu Whārangi. Ko te wahitau atanga e whakamahia ana ko A0xh me te nuinga o te waa e whakamahia ana mo nga raraunga tino nui penei i te whakahaere haukoti kia taea ai te panui kotahi-wa mo nga raraunga katoa e pa ana ki tetahi ahuatanga haukoti. Whai muri i te haukoti, kua kii a IntL, ka taea e te kaihautu te panui te mara haki ki te whakatau i te hongere kua pa me te momo haki.
Ko te Page02 he EEPROM Kaiwhakamahi me tana whakatakotoranga e te kaiwhakamahi.
