Ā, ko ngā kōwae whatu 100G QSFP28 LR4 me ngā kōwae whatu 100G QSFP28 CWDM4 e whakamahia tahitia ana me ngā taura papaki muka aratau-kotahi LC takirua, mā te whakamahi i te hanganga waea muka-rua SMF takirua.
4. He rerekē te kaupapa mahi
He rite tonu te kaupapa mahi o te waeine whatu 100G QSFP28 SR4 me te waeine whatu 100G QSFP28 PSM4. Ina tukuna ngā tohu i te pito tuku, ka hurihia ngā tohu hiko hei tohu whatu e te huinga taiaho, kātahi ka tukuna whakarara i runga i te muka whatu. Ina tae ki te pito whiwhi, ka hurihia e te huinga kite whakaahua ngā tohu whatu whakarara hei tohu hiko whakarara, engari ko te mea tuatahi kei runga i te muka maha-aratau, ko te mea tuarua kei runga i te muka kotahi-aratau.
He rite tonu te kaupapa mahi o te waeine whatu 100G QSFP28 LR4 me te waeine whatu 100G QSFP28 CWDM4. Ka hurihia e rāua ngā tohu hiko 4 25Gbps ki ngā tohu whatu LAN WDM e 4, kātahi ka whakareatia ki te hongere kotahi hei whakatutuki i te tuku whatu 100G. I te pito whiwhi, ka wehea e te waeine te whakaurunga whatu 100G ki ngā tohu whatu LAN WDM e 4, kātahi ka hurihia ki ngā hongere putanga tohu hiko e 4.
Kōwhiringa tono o te kōwae whatu 100G QSFP28
I raro i te whatunga 100G, me pēhea te whiriwhiri i tētahi kōwae whatu 100G QSFP28 e tika ana ka taea te whakaaro mai i ngā āhuatanga e toru e whai ake nei:
1. Taura muka whatu aratau maha i waenga i ngā pana: 5-100m
He kōwae whatu 100G QSFP28 SR4 whiriwhiri, e whakamahi ana i te atanga MTP (8 matua), ko te tawhiti tuku ina whakamahia me te muka aratau maha OM3 he 70m, ā, ina whakamahia me te muka aratau maha OM4, ko te tawhiti tuku he 100m, he pai mō te tuku tawhiti-poto (He iti iho i te 100 mita te tawhiti) i roto i te whatunga 100G.
2. Waea muka aratau-kotahi i waenga i ngā pana: >100m-2km
Ka taea e koe te whiriwhiri i te kōwae whatu 100G QSFP28 PSM4, i te kōwae whatu 100G QSFP28 CWDM4 rānei, e rua ngā mea e pai ana mō ngā whatunga tawhiti waenga me te tawhiti poto 100G. E 8 ngā muka whatu aratau-kotahi whakarara e whakamahia ana e te kōwae whatu 100G QSFP28 PSM4, ā, ko te tawhiti tuku he tata ki te 500 mita; ka whakamahia te kōwae whatu 100G QSFP28 CWDM4 me te muka whatu aratau-kotahi, ā, ka taea e te tawhiti tuku te tae ki te 2 km.
3. Muka aratau-kotahi roa: ≤10km
Ka taea te whiriwhiri i te kōwae whatu 100G QSFP28 LR4, ka whakamahia e ia te atanga LC takirua, ka taea e te tawhiti tuku te tae ki te 10km ina whakamahia me te muka aratau-kotahi, e tika ana mō te whatunga 100G tawhiti-roa (tawhiti neke atu i te 2 kiromita me te iti iho i te 10 kiromita).
Ka taea e HUANET te whakarato i ēnei kōwae whatu 100G QSFP28 katoa me te utu whakataetae, nau mai ki te tuku patai mai ki a mātou.
