3. Hanganga waea rereke
Ko te hanganga waea o te 100G QSFP28 SR4 kōwae whatu me te 100G QSFP28 PSM4 kōwae whatu he rite, me te hiahia e rua he hanganga waea muka-maha i runga i te 12-ara MMF MTP atanga.Ko te rereketanga ko te 100G QSFP28 PSM4 kōwae whatu me mahi i roto i te muka aratau kotahi Ko te 100G QSFP28 SR4 kōwae whatu kei roto i te muka aratau maha.
A ko 100G QSFP28 LR4 kōwae whatu me 100G QSFP28 CWDM4 kōwae whatu e te nuinga o whakamahia tahi me LC duplex kotahi-aratau muka papaki taura, whakamahi rua-pass rua-muka SMF hanganga waea.
4. He rereke te kaupapa mahi
Ko te kaupapa mahi o te 100G QSFP28 SR4 kōwae whatu me te 100G QSFP28 PSM4 kōwae whatu he waiwai rite.I te wa e tuku ana i nga tohu i te mutunga o te tuku, ka huri nga tohu hiko ki nga tohu whatu e te raupapa laser, katahi ka tuku whakarara i runga i te muka whatu.Ka tae atu ki te mutunga whiwhi, Ka huri te huinga kaitirotiro whakaahua i nga tohu whatu whakarara ki nga tohu hiko whakarara, engari ko te mea o mua kei runga i te muka aratau-maha, ko te mea whakamutunga kei runga i te muka aratau kotahi.
Ko te kaupapa mahi o te 100G QSFP28 LR4 kōwae whatu me te 100G QSFP28 CWDM4 kōwae whatu he rite.Ka hurihia e raua nga tohu hiko 4 25Gbps ki nga tohu whatu LAN WDM e 4, ka maha ki te hongere kotahi hei whakatutuki i te tuku whatu 100G.I te mutunga o te whiwhinga, ka whakakorehia e te kōwae te whakaurunga whatu 100G ki roto i nga tohu whatu LAN WDM 4, ka huri ki roto i nga awa whakaputa tohu hiko e 4.
Te whiriwhiringa tono o te 100G QSFP28 kōwae whatu
I raro i te whatunga 100G, me pehea te whiriwhiri i tetahi waahanga mata 100G QSFP28 ka taea te whakaaro mai i nga waahanga e toru e whai ake nei:
1. Multimode muka whatu taura i waenganui i whakakā: 5-100m
Kōwhiringa 100G QSFP28 SR4 kōwae whatu, e whakamahi ana i te atanga MTP (8 cores), te tawhiti tuku ina whakamahia ki te OM3 multimode muka ko 70m, a ka whakamahia ki te OM4 multimode muka, ko te tawhiti tuku he 100m, e tika ana mo te whakawhiti tawhiti poto (Ko te he iti iho te tawhiti i te 100 mita) i te whatunga 100G.
2. Waea muka aratau kotahi i waenga i nga whakawhiti:>100m-2km
Ka taea e koe te whiriwhiri 100G QSFP28 PSM4 kōwae whatu ranei 100G QSFP28 CWDM4 kōwae whatu, e pai e rua mo te reo me te tawhiti poto 100G whatunga.Ko te 100G QSFP28 PSM4 kōwae whatu whakamahi 8 whakarara kotahi-aratau muka whatu tahi, a ko te tawhiti tuku he tata ki te 500 mita;te 100G QSFP28 CWDM4 kōwae whatu e whakamahia tahi me te muka whatu aratau kotahi, a ka taea e te tawhiti tuku 2 km.
3. Roa-aratau muka kotahi-aratau: ≤10km
Ka taea e ia te whiriwhiri i te 100G QSFP28 LR4 kōwae whatu, ka tangohia e ia te atanga LC duplex, te tawhiti tuku ka tae ki te 10km ka whakamahia me te muka aratau kotahi, e tika ana mo te whatunga 100G tawhiti-roa (te tawhiti atu i te 2 kiromita me te iti iho i te 10 kiromita).
Ka taea e HUANET te whakarato i enei waahanga 100G QSFP28 optical katoa me te utu whakataetae, nau mai ki te tuku patai.
