Hoʻoholo ʻia nā mana kikowaena data e nā kikowaena, nā hoʻololi, a me nā mea pili e kaulike ana kekahi i kekahi a hoʻokau kekahi i kekahi i ka ulu wikiwiki a me ka haʻahaʻa.ʻO ka ʻenehana hoʻololi ka mea hoʻoikaika nui no nā makahiki he nui.Ke hoʻopau nei ʻo OFC2021 i kēia manawa, ua hōʻike nā mea hana kamaʻilio optical e like me Intel, Finisar, Xechuang, Opticexpress a me New Yisheng i nā modula optical 800G series.I ka manawa like, ua hōʻike nā hui chip chip o waho i nā huahana chip kiʻekiʻe no 800G, a loaʻa paha i ka papahana kuʻuna kahi wahi i ka wā 800G.Manaʻo mākou ʻo 800G optical module ʻenehana ala ʻoi aku ka maʻalahi, ʻo 800GDR8 a me 2 * FR4 ka mea nui loa;E like me ka OFC2021 mainstream optical module a me nā ʻoihana chip optical i hoʻokumu i nā huahana hou i kēlā me kēia, ua wehewehe ʻia ka manawa node a me ke ala ʻenehana nui o ka hoʻonui ʻana 800G.Ke hoʻomau nei ka helu o ka ʻoihana kikowaena optical module, a ua hoʻoholo ʻia ke ʻano ulu ulu lōʻihi.Ke manaʻoʻiʻo nei mākou i ka wā o ka digitalization a me ka naʻauao, ʻo ka pahū mau ʻana o nā kikowaena kikowaena data i lawe mai i ka koi no ka hoʻomau mau ʻana o nā modules optical.ʻO ke ala ʻenehana maʻemaʻe o 800G e hōʻike ana he 400G ka nui.
Ke hoʻonui ʻia ka helu hōʻailona 25Gbps i ka helu hōʻailona 56Gbps o kēia manawa, ma muli o ka hoʻokomo ʻia ʻana o ka ʻōnaehana hōʻailona PAM4 (Pulse Amplitude Modulation) (hui IEEE 802.3BS), ʻO ka helu alapine kumu o ka hōʻailona i lawe ʻia ma ka loulou Serdes Ethernet ke neʻe wale nei i luna. mai ka 12.89ghz a i ka 13.28ghz, a ʻaʻole loli nui ka helu alapine kumu.Hiki ke hoʻonui ʻia nā ʻōnaehana hiki ke kākoʻo i ka hoʻouna maikaʻi ʻana i nā hōʻailona 25Gbps i nā helu hōʻailona 56Gbps me ka hoʻonui iki.ʻAʻole maʻalahi ka hoʻonui ʻana mai ka helu hōʻailona 56Gbps i ka 112Gbps.ʻO ka ʻōnaehana hōʻailona PAM4 i hoʻokomo ʻia i ka wā i kūkulu ʻia ai ka maʻamau helu 56Gbps e hoʻohana hou ʻia ma nā pākēneka 112Gbps.Hoʻololi kēia i ka helu alapine kumu o ka hōʻailona Ethernet 112Gbps i 26.56ghz, ʻo ia ka pālua o ka helu hōʻailona 56Gbps.I ka hanauna o ka helu 112Gbps, e kū ana nā koi ʻenehana kelepona i kahi hoʻāʻo koʻikoʻi.I kēia manawa, pili ka 400Gbps kiʻekiʻe-wikiwiki i ka huahana.ʻO nā lama oʻo mua he mau lama haole, e like me TE, LEONI, MOLEX, Amphenol, a me nā mea ʻē aʻe.Mai ke kaʻina hana, nā mea hana a me nā mea hana, ua hana mākou i nā mea hou.I kēia manawa, aia nā ʻoihana kūloko e hana ana i ke kaula keleawe 800G, akā ʻaʻole mākou i hōʻiliʻili nui.ʻO Shenzhen Hongteda, Dongguan Zhongyou Electronics, Dongguan Jinxinuo, Shenzhen Simic Communication, a me nā mea ʻē aʻe, akā ʻo ka pilikia ʻenehana i kēia manawa aia ma ka ʻāpana uea ʻole.I kēia manawa, paʻakikī ka hoʻoponopono ʻana i nā ʻāpana hana uila uila kiʻekiʻe a me nā koi palupalu o nā wili uila i ka manawa like.E kū ana ke kaula keleawe DAC i kahi manawa o ka hoʻomohala wikiwiki.He ʻuʻuku wale nō nā mea hana uea kūloko.
Ke loli wikiwiki nei ka mākeke, a ʻoi aku ka wikiwiki i ka wā e hiki mai ana.ʻO ka nūhou maikaʻi ʻo ia ka holomua nui a me ka hoʻohiki ʻana, mai nā kino kūlana i ka ʻoihana, e hiki ai i nā kikowaena data ke neʻe i 400GB a me 800GB.Akā ʻo ka wehe ʻana i nā pale ʻenehana he hapalua wale nō ka paʻakikī.ʻO ka hapa ʻē aʻe ka manawa.Ke loaʻa ka manaʻo hewa, e ʻoi aku ka nui o ke kumukūʻai.ʻO 100G ka mea nui o ke kikowaena ʻikepili kūloko.Ma waena o nā kikowaena data 100G i hoʻonohonoho ʻia, 25% he keleawe, 50% he multi-mode fiber, a ʻo 25% he fiber-module fiber.ʻAʻole pololei kēia mau helu kikoʻī, akā ʻo ka ulu ʻana o ka noi no ka bandwidth, ka hiki, a me ka latency haʻahaʻa ke alakaʻi nei i ka neʻe ʻana i ka wikiwiki o ka pūnaewele.No laila i kēlā me kēia makahiki, he hoʻāʻo ka hoʻololi ʻana a me ka hiki ʻana o nā kikowaena data cloud nui.I kēia manawa, ke kahe nei ʻo 100GB i ka mākeke, me 400GB i manaʻo ʻia i ka makahiki aʻe.ʻOiai kēia, ke hoʻomau nei ka hoʻonui ʻana o ka ʻikepili, e hoʻomau ka piʻi ʻana o ke kaomi ma nā kikowaena data, ma hope o 400G, QSFP-DD 800G ua hiki mai.
