He aha nga tohu o te mahi maramara whatu whatu transceiver?
1. Mahi whakahaere whatunga
Kaore e taea e te whakahaere whatunga anake te whakapai ake i te pai o te whatunga, engari ano hoki te whakapumau i te pono o te whatunga.Heoi, ko te tangata me nga rauemi rauemi e hiahiatia ana ki te whakawhanake i te whakawhiti muka whatu me te mahi whakahaere whatunga tawhiti atu i era o nga hua rite ki te kore whakahaere whatunga, e kitea ana i roto i nga waahanga e wha: te haumi taputapu, te haumi rorohiko, te mahi patuiro, me te haumi kaimahi.
1. Te haumi taputapu
Ki te mohio ki te mahi whakahaere whatunga o te whatu whatu whatu transceiver, he mea tika ki te whirihora i te waeine tukatuka mōhiohio whakahaere whatunga i runga i te poari ara iahiko o te transceiver ki te tukatuka i te mōhiohio whakahaere whatunga.Na roto i tenei waahanga, ka whakamahia te atanga whakahaere o te maramara whakawhiti reo ki te tiki korero whakahaere, ka tohatohahia nga korero whakahaere ki nga raraunga noa i runga i te whatunga.hongere raraunga.He maha ake nga momo me te maha o nga waahanga o nga kaiwhakawhiti muka whatu me nga mahi whakahaere whatunga i nga hua rite kaore he whakahaere whatunga.Ka rite, he uaua te waea, he roa te huringa whanaketanga.
2. Pūmanawa haumi
I tua atu i nga waea waea taputapu, he mea nui ake te kaupapa rorohiko i roto i te rangahau me te whakawhanaketanga o nga whakawhiti whakawhiti muka Ethernet me nga mahi whakahaere whatunga.He nui te mahi whakawhanaketanga o te rorohiko whakahaere whatunga, tae atu ki te waahanga o te atanga kaiwhakamahi whakairoiro, te waahanga o te punaha whakauru o te waahanga whakahaere whatunga, me te waahanga o te waahanga tukatuka korero whakahaere whatunga i runga i te papaaahi whakawhiti whakawhiti.I roto i a raatau, ko te punaha whakauru o te waahanga whakahaere whatunga he tino uaua, he tiketike te paepae R&D, me whakamahi he punaha whakahaere whakauru.
3. Mahi patuiro
Ko te patuiro o te whakawhiti whatu Ethernet me te mahi whakahaere whatunga kei roto e rua nga waahanga: te patuiro rorohiko me te patuiro taputapu.I te wa o te patuiro, ko nga mea katoa i roto i te ararere poari, te mahinga o nga waahanga, te whakapiri i nga waahanga, te kounga o te poari PCB, nga ahuatanga o te taiao, me nga kaupapa rorohiko ka pa ki te mahi a te kaiwhakawhiti whatu muka Ethernet.Ko nga kaimahi patuiro me whai kounga matawhānui, me te whai whakaaro nui ki nga momo ahuatanga o te rahunga whakawhiti.
4. Te whakaurunga o nga kaimahi
Ko te hoahoa o nga kaiwhakawhitiwhiti muka whatu Itarangi ka taea e te miihini miihini kotahi anake te whakaoti.Ko te hoahoatanga o te whakawhiti i te muka whatu Itarangi me te mahi whakahaere whatunga ehara i te mea ko nga miihini taputapu ki te whakaoti i nga waea a te poari ara iahiko, engari he maha nga miihini rorohiko ki te whakaoti i te kaupapa whakahaere whatunga, me te mahi tahi i waenga i nga kaihanga rorohiko me nga taputapu.
2. Hototahi
Me tautoko te OEMC i nga paerewa whakawhitiwhiti whatunga noa penei i te IEEE802, CISCO ISL, me etahi atu, hei whakarite kia pai te hototahi o nga whakawhiti whakawhiti muka.
3. Nga whakaritenga taiao
a.Ko te ngaohiko whakauru me te whakaputa me te ngaohiko mahi o te OEMC ko te nuinga o te 5 volts, te 3.3 volts ranei, engari ko tetahi atu taputapu nui i runga i te Ethernet fiber optic transceiver - ko te ngaohiko mahi o te waahanga transceiver whatu te nuinga o te 5 volts.Mena kaore i te rite nga ngaohiko whakahaere e rua, ka nui ake te uaua o te waea papa PCB.
b.Te pāmahana mahi.I te wa e whiriwhiri ana i te pāmahana mahi o OEMC, me timata nga kaiwhakawhanake mai i nga ahuatanga tino kino ka waiho he waahi mo tera.Hei tauira, ko te pāmahana teitei i te raumati ko te 40°C, a ko te roto o te tahuhu whatu whatu transceiver ka whakamahana e nga momo waahanga, ina koa ko te OEMC..Na reira, te taupū rohe runga o te pāmahana whakahaere o te Itarangi muka whatu transceiver kia te tikanga e kore e iti iho i te 50 °C.
