400GBASE-SR4.2 QSFP-DD PAM4 850nm 100m DOM MPO-12/UPC MMF Optical Transceiver Module, Breakout i 4 x 100G-SR1.2
Wehewehena
+ ʻO ka module fiber optic KCO-QDD-400G-SR4.2-BD he 400GBASE-SR4 Cisco Compatible QSFP-DD (Quad Small Form-Factor Pluggable – Double Density) Bi-Direction optical Transceiver i hoʻolālā ʻia no ka hana ma luna o Multi-Mode Fiber (MMF).
+ ʻO ka module KCO-QDD-400G-SR4.2-BD 400GBASE-SR4.2, ka mea hoʻohui MTP/MPO-12, a hiki i 150m ma luna o ka fiber multi-mode OM4 OM5 like.
+ Hiki i ka KCO-QDD-400G-SR4.2-BD ke kākoʻo i nā loulou Ethernet a hiki i 400 Gigabits a hiki i ʻehā mau lōʻihi loulou breakout Ethernet 100 Gigabit.
+ ʻO ka module fiber optic KCO-QDD-400G-SR4.2-BD kahi transceiver QSFP-DD no 400G Ethernet, i hoʻohana pinepine ʻia i nā kikowaena ʻikepili no nā loulou pōkole, kiʻekiʻe-density a hiki i 100 mika ma luna o ka fiber multi-mode.
+ ʻO kāna noi nui no ka breakout 400G a i 4x100G, e ʻae ana i kahi awa 400G hoʻokahi e hoʻokaʻawale ʻia i ʻehā mau awa 100G e hoʻopili ai i nā kikowaena he nui a i ʻole nā mea hana pūnaewele. Hōʻike ka "BD" e hoʻohana ana i nā ala bidirectional me ʻelua mau nalu 50G ma nā hui fiber like, e koi ana i kahi module i hui pū ʻia me nā nalu hoʻohui e hoʻopau i ka pilina.
+ Ua kūlike ia me ke kaʻina hana IEEE 802.3 a me ke kūlana 400GAUI-8/PAM4.
+ ʻO ka nānā ʻana i nā diagnostics kikohoʻe i kūkulu ʻia (DDM) e ʻae i ke komo ʻana i nā palena hana manawa maoli. He kūpono ia no nā noi interconnect kikowaena ʻikepili 400G ethernet a me nā kikowaena ʻikepili.
+ Hiki iā ia ke kākoʻo i ka 4 × 100G-SR1.2.
+ Ua hōʻoia ʻia ke kūlike ma Arista/NVIDIA/Cisco RoCE Networking.
+Hoʻopili kikowaena ʻikepili Ethernet 400G no ka noi
Pōmaikaʻi
+Nā Hoʻonā Hoʻohui:Loulou 400G-a-400G no ke kuapo-a-kuʻi, 400G-a-ʻehā Loulou 100G no ke kuapo-a-kuʻi
+Ka Hana Alakaʻi a me ka Kūlana no 100G: Me ka Chip Broadcom i kūkulu ʻia a ua lako me ka pahu BOX i hoʻolālā ʻia pākahi, hāʻawi ka transceiver QSFP28 i ka wikiwiki kiʻekiʻe a me ka mana haʻahaʻa i nā loulou 100G.
+Ua hoʻāʻo ʻia ma nā polokalamu kikowaena no ka Interoperability i hōʻoia ʻia: Ua hoʻāʻo ʻia kēlā me kēia ʻāpana no ka hoʻohālikelike ʻana i loko o ke kaiapuni kuapo i manaʻo ʻia, ka mea e hōʻoiaʻiʻo ai i nā hana kīnā ʻole.
+E hoʻā i ka pilina maʻalahi no kāu pūnaewele:Ke hoʻonohonoho hou nei i ka transceiver e hana me nā lama like ʻole.
