400GBASE-SR4.2 QSFP-DD PAM4 850nm 100m DOM MPO-12/UPC MMF Optical Transceiver Module, Breakout i 4 x 100G-SR1.2
wehewehe
+ ʻO ka KCO-QDD-400G-SR4.2-BD fiber optic module 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 KCO-QDD-400G-SR4.2-BD 400GBASE-SR4.2 module, MTP/MPO-12 connector, a hiki i 150m ma luna o ka OM4 OM5 multi-mode fiber.
+ Hiki i ka KCO-QDD-400G-SR4.2-BD ke kākoʻo i nā loulou Ethernet a hiki i 400 Gigabits a hiki i ʻehā 100 Gigabit Ethernet breakout ka lōʻihi.
+ ʻO ka KCO-QDD-400G-SR4.2-BD fiber optic module he QSFP-DD transceiver no 400G Ethernet, maʻamau i hoʻohana ʻia i loko o nā kikowaena ʻikepili no ka lōʻihi pōkole, nā loulou kiʻekiʻe a hiki i 100 mika ma luna o ka fiber mode multi-mode.
+ ʻO kāna noi mua no 400G a 4x100G breakout, e ʻae ana i kahi awa 400G hoʻokahi e hoʻokaʻawale ʻia i ʻehā mau awa 100G e hoʻopili ai i nā kikowaena lehulehu a i ʻole nā mea hana pūnaewele. Hōʻike ka "BD" i ka hoʻohana ʻana i nā ala bidirectional me ʻelua mau hawewe 50G ma nā paʻa fiber parallel, e koi ana i kahi module i hoʻohui ʻia me nā lōʻihi hawewe e hoʻopau ai i ka pilina.
+ He kūpono ia i ka protocol IEEE 802.3 a me ka maʻamau 400GAUI-8/PAM4.
+ ʻO ka nānā ʻana i nā diagnostics digital i kūkulu ʻia (DDM) hiki ke komo i nā ʻāpana hana manawa maoli. He kūpono ia no ka 400G ethernet a me nā noi kikowaena kikowaena data.
+ Hiki iā ia ke kākoʻo iā 4 × 100G-SR1.2.
+ Hōʻoia ʻia ka hoʻohālikelike ʻana ma Arista/NVIDIA/Cisco RoCE Networking.
+ Noi 400G Ethernet Data Center Interconnect
Pōmaikaʻi
+Nā mea e hoʻopili ai:400G-a-400G Link no ka Switch-to-Switch, 400G-to-4 100G Links no Switch-to-Switch
+Ke alakaʻi i ka hana a me ka maikaʻi no 100G: Me ka Broadcom Chip i kūkulu ʻia a hoʻolako ʻia me ka pahu pahu BOX i hoʻolālā ʻia, hāʻawi ka transceiver QSFP28 i ka wikiwiki kiʻekiʻe a me ka mana haʻahaʻa i nā loulou 100G.
+Hoʻāʻo ʻia i nā mea hoʻokipa no ka hoʻāʻo ʻana i ka Interoperability: Hoʻāʻo maikaʻi ʻia kēlā me kēia ʻāpana no ka hoʻohālikelike ʻana i ke kaiapuni hoʻololi i manaʻo ʻia, e hōʻoiaʻiʻo ana i nā hana kīnā ʻole.
+E ho'ā i ka hoʻohui pono ʻole no kāu pūnaewele:Hoʻonohonoho hou i ka transceiver e hana me nā hōʻailona like ʻole.
