400GBASE-SR4.2 QSFP-DD PAM4 850nm 100m DOM MPO-12/UPC MMF Module Whakawhiti Whatu, Wehenga ki te 4 x 100G-SR1.2
Whakaahuatanga
+ Ko te kōwae muka whatu KCO-QDD-400G-SR4.2-BD he Kaiwhakawhiti Whatu Bi-Direction QSFP-DD (Quad Small Form-Factor Pluggable – Double Density) e hototahi ana ki a Cisco 400GBASE-SR4, i hangaia hei whakahaere i runga i te muka maha-aratau (MMF).
+ Ko te kōwae KCO-QDD-400G-SR4.2-BD 400GBASE-SR4.2, hononga MTP/MPO-12, tae atu ki te 150m i runga i te muka maha-aratau OM4 OM5 whakarara.
+ Ka taea e te KCO-QDD-400G-SR4.2-BD te tautoko i ngā hononga Ethernet tae atu ki te 400 Gigabits me te wha o ngā roa hononga pakaru Ethernet 100 Gigabit.
+ Ko te kōwae muka whatu KCO-QDD-400G-SR4.2-BD he taputapu whakawhiti QSFP-DD mō te Ethernet 400G, e whakamahia ana i roto i ngā pokapū raraunga mō ngā hononga poto-te-tae, teitei-kiato tae atu ki te 100 mita i runga i te muka maha-aratau.
+ Ko tōna whakamahinga matua he mea hei wehe i te 400G ki te 4x100G, e āhei ai te wehewehe i tētahi tauranga 400G kotahi kia whā ngā tauranga 100G hei hono atu ki ngā tūmau maha, ki ngā taputapu whatunga rānei. Ko te "BD" e tohu ana ka whakamahia e ia ngā ara rua-aronga me ngā roangaru 50G e rua i runga i ngā takirua muka whakarara, me te hiahia kia kotahi te waeine takirua me ngā roangaru tautoko hei whakaoti i te hononga.
+ E tutuki ana i ngā whakaritenga o te kawa IEEE 802.3 me te paerewa 400GAUI-8/PAM4.
+ Mā te aroturuki tātaritanga mamati (DDM) kua hangaia ki roto ka taea te uru atu ki ngā tawhā whakahaere wā-tūturu. He pai mō ngā tono hononga whatunga ethernet 400G me ngā pokapū raraunga.
+ Ka taea te tautoko i te 4× 100G-SR1.2.
+ Kua Manatokohia te Hototahi i roto i te Whatunga Arista/NVIDIA/Cisco RoCE.
+Taupānga Hononga Pokapū Raraunga Ipurangi 400G
Painga
+Ngā Otinga Hononga:Hononga 400G-ki-400G mō te Whakawhiti-ki-te-Whakawhiti, 400G-ki-te-whā Hononga 100G mō te Whakawhiti-ki-te-Whakawhiti
+Te Mahi me te Kounga Matua mō te 100G: He maramara Broadcom kua hangaia ki roto, ā, he takai pouaka kua hoahoatia takitahi hoki, ka tukuna e te taputapu whakawhiti QSFP28 te tere teitei me te mana iti i roto i ngā hononga 100G.
+Kua Whakamātauria i roto i ngā Pūrere Kaihautū mō te Taunekeneke Whakamātauhia: Ka whakamātauhia te kounga o ia waeine mō te hototahitanga i roto i te taiao pana kua tohua, e whakamana ana i te mahi tino pai.
+Whakahohehia te Hononga Maeneene mō tō Whatunga:Te whirihora anō i te pūwhakawhiti kia mahi tahi me ngā waitohu rerekē.
