10KM 40G QSFP+ Kōwae Whakawhitiwhiti Whatu
TeQSFP+ Kua hangaia ngā kōwae whakawhiti-whakawhiti hei whakamahi i roto i ngā hononga 40 Gigabit ia hekona i runga i te muka maha-aratau. E tutuki ana ēnei i te QSFP+ MSA me te IEEE 802.3ba 40GBASE-SR4. Kei roto i te wāhanga whakawhiti whatu o te whakawhiti-whakawhiti he huinga VCSEL (Poutū Ana o te Mata Emitting Laser) 4-hongere, he arai tāuru 4-hongere me te taraiwa laser, ngā poraka whakahaere me te taha whakahāngai. Kei roto i te wāhanga kaiwhiwhi whatu o te whakawhiti-whakawhiti he huinga photodiode PIN 4-hongere, he huinga TIA 4-hongere, he arai putanga 4-hongere, me ngā poraka whakahaere.

40KM 40G QSFP+ Pūrere Whakawhiti Whatu
TeHUAQ40EHe waeine whakawhiti-whakawhiti tēnei i hangaia mō ngā tono whakawhitiwhiti whatu 40Km. E tutuki ana te hoahoa i te 40GBASE-ER4 o te paerewa IEEE P802.3ba. Ka hurihia e te waeine ngā hongere whakauru e 4 (ch) o ngā raraunga hiko 10Gb/s ki ngā tohu whatu CWDM e 4, ā, ka whakareatia kia kotahi te hongere mō te tuku whatu 40Gb/s. I te taha whakamuri, i te taha kaiwhiwhi, ka wetewetehia e te waeine te whakaurunga 40Gb/s ki ngā tohu hongere CWDM e 4, ā, ka hurihia kia 4 ngā raraunga hiko putanga.
Ko ngā roangaru matua o ngā hongere CWDM e 4 ko 1271, 1291, 1311 me te 1331 nm hei mema o te whatunga roangaru CWDM kua tautuhia i roto i te ITU-T G694.2. Kei roto he hononga LC takirua mō te atanga whatu me te hononga 38-pine mō te atanga hiko. Hei whakaiti i te marara whatu i roto i te pūnaha tawhiti, me whakamahi te muka aratau kotahi (SMF) i roto i tēnei kōwae.
Kua hoahoatia te hua me te āhua āhua, te hononga whatu/hiko me te atanga tātaritanga mamati e ai ki te Whakaaetanga Maha-Pūtake QSFP (MSA). Kua hoahoatia kia tutuki ai ngā āhuatanga whakahaere o waho tino uaua tae atu ki te pāmahana, te haumākū me te pokanoa EMI.
Ka whakahaerehia te kōwae mai i tētahi pūtake hiko kotahi +3.3V, ā, kei te wātea ngā tohu whakahaere ā-ao LVCMOS/LVTTL pērā i te Module Present, Reset, Interrupt me te Low Power Mode me ngā kōwae. Kei te wātea he atanga raupapa 2-waea hei tuku me te whiwhi tohu whakahaere uaua ake, hei tiki hoki i ngā mōhiohio tātaritanga mamati. Ka taea te aro atu ki ngā hongere takitahi, ā, ka taea te whakaweto i ngā hongere kāore i whakamahia mō te ngāwari o te hoahoa.
Ka hurihia e tēnei hua ngā raraunga whakauru hiko 4-hongere 10Gb/s ki ngā tohu whatu CWDM (mārama), mā te whakamahi i tētahi huinga Taiaho Urupare Tohatoha 4-roa-ngaru (DFB) e peia ana. Ka whakakotahihia te mārama e ngā wāhanga MUX hei raraunga 40Gb/s, ka horapa atu i te waeine tuku mai i te SMF. Ka tangohia e te waeine kaiwhiwhi te whakaurunga tohu whatu CWDM 40Gb/s, ā, ka wetewetehia kia 4 ngā hongere 10Gb/s takitahi me ngā roangaru rerekē. Ka kohia ia mārama roangaru e tētahi photodiode avalanche motumotu (APD), kātahi ka tukuna hei raraunga hiko i muri i te whakanuia tuatahi e te TIA, kātahi e te whakakaha pou.
TeHUAQ40EKua hangaia me te āhua āhua, te hononga whatu/hiko me te atanga tātaritanga mamati e ai ki te Whakaaetanga Pūtake Maha QSFP (MSA). Kua hangaia kia tutuki ai ngā āhuatanga whakahaere o waho tino uaua tae atu ki te pāmahana, te haumākū me te pokanoa EMI. He tino teitei te mahi a te kōwae me te whakaurunga āhuatanga, ka taea te uru atu mā te atanga raupapa waea-rua.
