Pokapū Raraunga
1. He aha te pokapū raraunga?
I te tau 1946, i te Whare Wānanga o Pennsylvania i te United States, i hangaia e John von Neumann te rorohiko tuatahi mō ngā kaupapa whānui mō te tangata. E noho ana i te rahi o te 170 mita tapawha, he rahi noa iho tēnei mō tētahi taputapu. Mai i taua wā, kua whakatuwherahia e te tangata te tatau ki te rorohiko whānui. I te ngaru o te mōhiohio Ipurangi, kua tirohia, kua whakawhanakehia e te ao ngā taputapu rorohiko. Nā reira, he maha ngā taputapu e hiahia ana ki te whakahaere i te pokapū, nā reira kua tukuna, kua whakahoutia e te tangata ngā paerewa hanga pokapū raraunga, e kī ana i te pokapū raraunga he wāhi e whakahaerehia ana ngā taputapu o te pūnaha mōhiohio hiko.
2.Te taura pokapū raraunga Pakiri Kua whakatakotohia e ngā rongoā a te SOCT he turanga pakari mō te whanaketanga pūmau o te whakawhiti kōrero whatunga.
Ko te SOCT e whakatakoto ana i ngā ture here o te tāuru rara mo ngā tuarua rara. Ko te wāhitua tāuru rara o te tuarua rara kei te noho tonu mai i te ruma tūhura, te wāhi whakawehe matua, te wāhi whakawehe tuatahitia, te wāhi whakawehe rohe, te wāhi whakawehe taketake, me te wāhi whakawehe ā-rorohiko. E whāngaihia ana te rākau tāuru ki ngā rākau whakawehe matua me ngā rākau whakawehe taketake. Kia whai mana ai i te tino whenua o te tāuru rara, ko te kaha o te SOCT he 12-144 ngā pū kapa tāuru e tūhono ana i mua o te tāuru rara. Ki te rākau whakawehe taketake, e tūhonotia ana ngā tāwhiti pū nui, ā, ko ngā rākau tūhonotia me ngā rākau tūhonotia kore hoki hei whakawehe i ngā rākau Category 8 me Category 6A. Ko ētahi atu, ko ngā tāwhiti tūhonotia hei whakamahia mo te rākau tāuru pū, pērā mai i te MPO, LC, ā, hei whakawhitinga me te tīrikatanga i waenganui i ngā wāhi tāuru katoa.
3. Me pēhea te hono i ngā taura MPO Patch mai i te 10G ki te 40G I te Pokapū Raraunga?
Whakamahia ngā 4 LC-LC jumpers ki te hono i ngā 4 10G SFP+ mōkī ātea i tētahi pito.
Whakamahia ngā jumpers MPO 12-core ki te hono i ngā mōkī optical 40G i tētahi pito
Whakamahia ngā pouaka fiber optic teitei teitei me ngā pouaka mōkī kua oti te whakatū i te pokapū hei whakatutuki i ngā whakaritenga whakawhiti o 10G ki 40G
4. Me pēhea te whakatakoto i ngā taura mō tētahi pokapū raraunga 400G?
- Rongoā 1: 400G-DR4 ki 4x100G-DR
Ka hono te mōkī optical QSFP ki te jumper LC, ā, ka hono ki tētahi pito o te taura optical MTP trunk mā te MTP ki te LC mōkī o te pātene patch teitei teitei, ā, ko te pito kē o te taura optical MTP trunk ka hono ki te mōkī QSFP-DD e hono ana ki te jumper MTP 8-core mā te pātene adapter MTP o te pātene patch teitei teitei.
- Rongoā 2: 400G-SR8 ki 2x200G-SR4
Te hono i waenganui i te mōkī QSFP-DD me te mōkī QSFP28, whakatakotoria he taura MTP-MTP kua oti te whakatū i waenganui i ngā pāra.
Whakatakotoria he taura patch fiber MTP 8-core i te taha pāra 200G.
Whakatakotoria he taura patch MTP16-core ki 2X8-core i te taha pāra 400G hei hono i te mōkī QSFP-DD
Tūhono te pouaka tohatoha fiber teitei i waenga i te taura trunk kua oti te whakaritenga me te cord patch fiber, ā, whakahaerehia me te kaiwhakatū MTP
