40KM 40G QSFP + Kōwae Whakawhiti Matapihi
Ko teHUAQ40Ehe kōwae whakawhiti i hangaia mo te 40Km tono whakawhitiwhiti whakaaro.He pai te hoahoa ki te 40GBASE-ER4 o te paerewa IEEE P802.3ba.Ka hurihia e te kōwae nga hongere whakauru 4(ch) o nga raraunga hiko 10Gb/s ki nga tohu whatu CWDM 4, ka whakatiki ki te hongere kotahi mo te tuku whatu 40Gb/s.I tua atu, i te taha o te kaiwhiwhi, ka whakakorehia e te kōwae te maha o te whakaurunga 40Gb/s ki roto i nga tohu hongere 4 CWDM, ka huri ki nga raraunga hiko whakaputa 4.
Ko nga roangaru o waenganui o nga waahana 4 CWDM ko 1271, 1291, 1311 me 1331 nm hei mema o te mahinga roangaru CWDM kua tautuhia i roto i te ITU-T G694.2.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 ahua, te hononga whatu/hiko me te atanga tātaritanga mamati e ai ki te QSFP Multi-Source Agreement (MSA).Kua hoahoatia kia tutuki i nga tikanga whakahaere o waho rawa atu tae atu ki te pāmahana, te makuku me te EMI interference.
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.
Ka hurihia e tenei hua nga raraunga whakauru hiko 4-channel 10Gb/s ki nga tohu whatu CWDM (marama), na te raupapa 4-wavelength Distributed Feedback Laser (DFB) kua peia.Ko te rama ka whakakotahihia e nga waahanga MUX hei raraunga 40Gb / s, ka tohatoha mai i te waahanga whakawhiti mai i te SMF.Ka whakaaehia e te kōwae kaikawe te whakaurunga tohu tohu 40Gb/s CWDM, ka whakakore i te maha o nga hongere 10Gb/s me te roangaru rereke.Ko ia rama roangaru ka kohia e te whakaahua tohenga motuhake (APD), ka puta hei raraunga hiko i muri i te whakakaha tuatahi e te TIA, katahi ano ma te whakakaha pou.
Ko teHUAQ40Ekua hoahoatia me te ahua ahua, hononga whatu/hiko me te atanga tātaritanga mamati e ai ki te QSFP 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.
