ʻO ka "hoʻokūkū hoʻokūkū" ke ala maikaʻi loa e hōʻike ai i ka mākeke lako Optical Transport DWDM.ʻOiai he mākeke nui ia, aia ma kahi o $15 biliona, aia ma kahi o 20 mau mea hana ʻōnaehana e komo ikaika ana i ke kūʻai aku ʻana i nā lako DWDM a me ka hakakā ʻana no ka māhele mākeke.ʻO kēlā ʻōlelo, 90 pakeneka o ka mākeke e paʻa ʻia e nā mea kūʻai aku ʻehiku wale nō, e waiho ana he 10 pakeneka no nā mea kūʻai aku i koe, a ma waena o nā mea kūʻai aku ʻehiku, ʻoi aku ka nui o ka delta māhele mākeke - 25 pakeneka ma waena o ka mea kūʻai nui a me ka liʻiliʻi loa.
ʻO ka nui o ka ʻoihana a me ka hoʻopukapuka ʻana he mea ʻokoʻa nui e like me ka hoʻokaʻawale ʻana i ka mākeke, kahi i waena o nā mea kūʻai kiʻekiʻe, ma waho o FiberHome, ua hoʻokomo nā mea a pau i ka hoʻohui kū pono ʻana ma nā ʻaoʻao ʻaoʻao e like me ka DSP coherent a me ka hope optical.ʻAʻole ia he mea koʻikoʻi inā hoʻokumu ʻia ka hopena o mua ma Silicon Photonics (SiPh) a i ʻole Indium Phosphide (InP) ʻoiai ke hoʻomau nei nā poʻe loea i ka hoʻopaʻapaʻa ʻana i nā ʻenehana ʻelua.ʻO ka mea hoʻoholo, ua hoʻomohala ka ʻoihana i kahi ʻenehana i loko o ka hale e hoʻokaʻawale i nā huahana mai nā mea ʻē aʻe, e hoʻohaʻahaʻa i kāna kumukūʻai huahana, a hāʻawi i ka ʻoihana i kahi manawa maikaʻi e mākeke.Eia kekahi, no ka mea he nui ka nui a me nā kumu waiwai (kālā, kānaka, a me ka waiwai naʻauao) e hoʻomohala i kēia mau ʻāpana, hoʻohui ʻia ke kūpaʻa i mea e pale ai i nā mea komo hou (a me nā mea kahiko).
Loaʻa ka hoʻololi huahana
E like me ka hapa nui o nā ʻoihana, kahi ikaika o waho i ka ʻoihana Optical Transport ʻo ia ka hoʻololi huahana.ʻOiai ʻaʻole he mea hoʻoweliweli maoli ka hoʻololi ʻana i nā huahana i nā makahiki i hala aku nei, ma muli o nā pōmaikaʻi kūlohelohe i ka hana a me ke kumukūʻai o ka ʻenehana DWDM me nā kaohi o ka pae ʻōnaehana i ka hoʻokomo ʻana i ka ʻenehana DWDM i kahi paepae e pili ana, ke hoʻomaka nei ke kai e huli iki. mea liʻiliʻi 400ZR pluggable optics.Ma muli o kēia mau pluggable optics hou i loko o kahi QSFP-DD form factor e hiki ke hoʻouna i nā hawewe 400 Gbps a hiki i 120 mau kilomita, ke manaʻo nei mākou i ka ulu ʻana o ka hoihoi i IP-over-DWDM (IPoDWDM), ʻo ia kahi hoʻolālā ʻōnaehana e hoʻopili ai i ka DWDM. optics ma kahi Ethernet Switch a i ʻole Router.ʻO kēia, me ka ʻole o ka ʻōlelo ʻana, e hoʻonui i ka pae o ka hoʻokūkū ma ka wahi lako DWDM i ka wā e hoʻoholo ai nā mea kūʻai aku ma waena o ka hoʻohana ʻana i kahi ʻōnaehana DWDM maʻamau mai kā mākou mea kūʻai aku 20 DWDM a i ʻole kahi IPoDWDM pūnaewele mai nā mea kūʻai aku hoʻololi.(ʻO nā mea kūʻai aku ʻo Ethernet Switch a me Router ʻo Arista, Cisco, Juniper, a me Nokia).
Eia naʻe, e pōmaikaʻi ʻo 400ZR i nā mea kūʻai aku DWDM optical.ʻO ke kumu hoʻokahi, ʻaʻole makemake nā mea hana a pau e hoʻololi i kā lākou pūnaewele i IPoDWDM a koho lākou e hoʻohana i nā optics pluggable 400ZR ma kahi ʻōnaehana DWDM, e mālama ana i ka hoʻolālā pūnaewele me ka ʻole o ka hoʻololi ʻana i ka wā e pōmaikaʻi ana i ke kumu kūʻai haʻahaʻa o 400ZR optics.Akā ʻo kekahi kumu ʻē aʻe ʻo 400ZR kahi ʻenehana koʻikoʻi a no laila ua kūpono nā hui i hoʻokomo i kēia ʻenehana i nā makahiki he ʻumi i hala aku nei e hoʻoponopono i kēia manawa hou.No laila, ʻo nā mea hana o 400ZR pluggable optics ka hapa nui o nā hui i lōʻihi ka mōʻaukala i ka hoʻomohala ʻana i nā ʻōnaehana DWDM coherent, e like me Ciena, Cisco, a me Nokia.Ua manaʻo ʻo Huawei e hoʻomohala i kahi 400ZR pū kekahi, akā ʻaʻole maopopo mākou inā e hoʻopaneʻe ka US i ka ʻoihana i kēia hana.
Makemake nā mea kūʻai aku i nā mea hoʻolako kūloko ke loaʻa
Ma kekahi mau ʻano, ʻaʻole kēia he mea kahiko a ʻaʻole hou, akā he mea nui e haʻi hou i ka makemake o nā mea kūʻai aku e kūʻai i nā lako mai kahi mea hoʻolako kūloko.Ma kēia pakuhi, ua ʻoki ʻia ka mākeke mea hana DWDM honua i nā wahi nui a me nā mea kūʻai aku e hoʻolako i kahi ʻāina.ʻO ka nui o ka pahu e hōʻike ana i ka mea kūʻai aku ma ia wahi, a ʻo nā pahu pale ʻōmaʻomaʻo nā mea kūʻai aku i manaʻo ʻia he home no kēlā ʻāina.ʻAʻole ia he mea kupanaha ma nā ʻāpana ʻelua - ʻAmelika ʻĀkau a me Kina - kahi nui o nā mea kūʻai kūloko, hele ka nui o nā kūʻai aku DWDM i kēia mau ʻoihana kūloko.Ma muli o ke kiʻekiʻe o ka hui ʻana o nā ʻoihana i "nā ʻē aʻe," ʻaʻole wau i hoʻomalu i kēlā mau pahu, akā ma ʻAmelika ʻĀkau a me Kina ka hapa nui o nā "mea ʻē aʻe" he hui kūloko pū kekahi.
ʻO ka mea hoihoi paha ʻo nā pahu pale ʻole.ʻO ke kumu ma hope o ka kau ʻana o ka US i nā mea paʻa ma ZTE i ka makahiki 2018 a me Huawei hou, ua hopohopo nui nā mea lawelawe i nā wahi me ka nui o nā pahu pale ʻole (nā mea kūʻai ʻole home) i ka lako lako.ʻO ka hopena, ke nānā nei nā mea lawelawe e hoʻopau i ka pilikia ma ka hōʻemi ʻana i ka hilinaʻi ʻana i kekahi mea hoʻolako a me ka hoʻonui ʻana i ka noʻonoʻo ʻana o nā mea hoʻolako kūloko.Ma nā ʻano he nui, maikaʻi kēia no nā ʻoihana liʻiliʻi i hoʻokumu ʻia ma nā wahi kūloko e like me Tejas ma India, Padtec ma CALA, a me PacketLight ma EMEA.Eia nō naʻe, ma ke ʻano o ka hoʻopaʻa ʻana i ka pilikia, e hoʻomau paha nā mea lawelawe nui loa e kūʻai i ka hapa nui o nā mea hana mai nā mea hana DWDM nui aʻe i loaʻa ka paona a me ka ʻenehana e kākoʻo i kā lākou hana e hiki mai ana.
ʻO ke kūlana ikaika o ka ʻoihana
Malia paha ʻo ke ala maikaʻi loa e wehewehe ai i ke kūlana o ka ʻoihana mea hana WDM optical i kēia makahiki he "dynamic."'Ōlelo wau i kēia no ka mea ʻaʻole like i ka wā ma mua i ka like ʻana o nā pūʻali ʻoihana i kēlā me kēia makahiki, ua puka mai nā mana hou i ka ʻoihana optical i kēia makahiki e hiki ke hoʻololi hou iā ia.ʻO ka mea kikoʻī, ʻo nā mana hou aʻu e ʻōlelo nei ʻo ia ka hiki ke kiʻekiʻe o ka hoʻololi ʻana i nā huahana me IPoDWDM i hoʻohana ʻia e 400ZR i kahi plug QSFP-DD a me kahi hoʻololi i ka ʻano o ka mea kūʻai aku i hana ʻia e nā hana aupuni US ma luna o nā mea hana Kina i hiki ke hoʻololi i ka ʻāina mea kūʻai aku ma kekahi mau wahi. ua holo ʻoi aʻe ka manawa.
