ʻO ke ala maikaʻi loa e wehewehe ai i ka mākeke lako Optical Transport DWDM ʻo "ka hoʻokūkū nui". ʻOiai he mākeke nui ia, me ke kaumaha he $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 hoʻokūkū ikaika no ka māhele mākeke. ʻO kēlā ʻōlelo, 90 pakeneka o ka mākeke e paʻa ʻia e ʻehiku mau mea kūʻai aku, e waiho ana i 10 pakeneka no nā mea kūʻai aku i koe, a ma waena o nā ʻehiku kiʻekiʻe, nui ka delta māhele mākeke—25 mau helu pakeneka ma waena o ka mea kūʻai aku nui loa a me ka mea liʻiliʻi loa.
ʻO ke anawaena o ka ʻoihana a me ka hoʻopukapuka kālā he mea hoʻokaʻawale koʻikoʻi e hoʻokaʻawale ana i ka mākeke, kahi i waena o nā mea kūʻai aku kiʻekiʻe, ma waho o FiberHome, ua hoʻopukapuka kālā lākou a pau i ka hoʻohui kū pololei ma nā ʻāpana laina e like me ka DSP coherent a me ka optical front end. ʻAʻole ia he mea nui inā ua hoʻokumu ʻia ka optical front end ma Silicon Photonics (SiPh) a i ʻole Indium Phosphide (InP) ʻoiai ke hoʻomau nei nā pundits ʻoihana i ka hoʻopaʻapaʻa ʻana i nā ʻenehana ʻelua. ʻO ka mea hoʻoholo, ua hoʻomohala ka ʻoihana i kahi ʻenehana kūloko e hoʻokaʻawale i nā huahana mai nā mea ʻē aʻe, hoʻohaʻahaʻa i nā kumukūʻai huahana, a hāʻawi i ka ʻoihana i kahi manawa kūpono e kūʻai aku ai. Eia kekahi, ʻoiai he nui ka nui a me nā kumuwaiwai (kālā, kānaka, a me ka waiwai noʻonoʻo) e hoʻomohala i kēia mau ʻāpana, hana ka hoʻohui kū pololei i kahi pale i nā mea komo hou (a me nā mea kahiko).
Loaʻa ka pani huahana
E like me ka hapa nui o nā ʻoihana, he mana kūwaho i ka ʻoihana Optical Transport ka hoʻololi huahana. ʻOiai ʻaʻole he hoʻoweliweli maoli ka hoʻololi huahana i nā makahiki i hala, ma muli o nā pono kūlohelohe i ka hana a me ke kumukūʻai o ka ʻenehana DWDM me nā palena pae ʻōnaehana i ka hoʻokomo ʻana i ka ʻenehana DWDM i kahi kahua pili, ke hoʻomaka nei ke au e huli iki me ka mea liʻiliʻi 400ZR pluggable optics. Ma muli o kēia mau optics pluggable hou i loko o kahi mea ʻano QSFP-DD hiki ke hoʻouna i nā nalu 400 Gbps a hiki i 120 kilomita, ke manaʻo nei mākou i ka ulu ʻana o ka hoihoi i ka IP-over-DWDM (IPoDWDM), ʻo ia kahi hoʻolālā ʻōnaehana e hoʻokomo i nā optics DWDM i loko o kahi Ethernet Switch a i ʻole Router. E hoʻonui kēia, me ka ʻōlelo ʻole, 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 kuʻuna mai kā mākou mau mea kūʻai aku 20 DWDM a i ʻole kahi ʻōnaehana IPoDWDM mai nā mea kūʻai aku hoʻololi ʻē aʻe. (ʻO nā mea kūʻai aku Ethernet Switch a me Router kiʻekiʻe ʻo Arista, Cisco, Juniper, a me Nokia).
Eia nō naʻe, e pōmaikaʻi pū ka 400ZR i nā mea kūʻai aku optical DWDM. ʻO kekahi kumu, ʻaʻole makemake nā mea hana āpau e hoʻololi i kā lākou pūnaewele i IPoDWDM a e koho e hoʻohana i nā optics pluggable 400ZR ma kahi ʻōnaehana DWDM, e mālama ana i ka hoʻolālā pūnaewele i hoʻololi iki ʻia me ka pōmaikaʻi mai ke kumukūʻai haʻahaʻa o nā optics 400ZR. Akā ʻo kekahi kumu ʻē aʻe, he ʻenehana kūlike ʻo 400ZR a no laila ua kūpono nā hui i hoʻokomo i kēia ʻenehana i nā makahiki he ʻumi i hala e hoʻoponopono i kēia manawa hou. No laila, ʻo ka hapa nui o nā mea hana o nā optics pluggable 400ZR he mau hui i loaʻa ka mōʻaukala lōʻihi i ka hoʻomohala ʻana i nā ʻōnaehana DWDM kūlike, e like me Ciena, Cisco, a me Nokia. Ua manaʻo ʻo Huawei e hoʻomohala i kahi 400ZR pū kekahi, akā ʻaʻole mākou maopopo inā e hoʻopaneʻe nā kapu o US i ka hui 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 he mea hou paha, akā he mea nui e haʻi hou aku i ka mea maʻamau makemake nā mea kūʻai aku e kūʻai i nā lako mai kahi mea hoʻolako kūloko. Ma kēia pakuhi, ua ʻoki ʻia ka mākeke lako DWDM honua i nā ʻāpana nui a me nā mea kūʻai aku e hoʻolako ana i kahi ʻāpana i hāʻawi ʻia. Hōʻike ka nui o ka pahu i ka mahele o ka mea kūʻai aku ma ia ʻāpana, a ʻo nā pahu ʻōmaʻomaʻo i hoʻoluʻu ʻia nā mea kūʻai aku i manaʻo ʻia he kūloko no ia ʻāpana. ʻAʻole ia he mea kupanaha ma nā ʻāpana ʻelua—ʻAmelika ʻĀkau a me Kina—kahi i nui ai nā mea kūʻai aku kūloko, hele ka nui o nā kūʻai aku DWDM i kēia mau ʻoihana kūloko. Ma muli o ka hui nui ʻana o nā ʻoihana ma "nā poʻe ʻē aʻe," ʻaʻole au i hoʻoluʻu i kēlā mau pahu, akā ma ʻAmelika ʻĀkau a me Kina ʻo ka hapa nui o "nā poʻe ʻē aʻe" he mau ʻoihana kūloko pū kekahi.
ʻO ka mea hoihoi paha, ʻo ia nā pahu i uhi ʻole ʻia. ʻO ke kumu, ma hope o ke kau ʻana o ʻAmelika Hui Pū ʻIa i nā kapu ma ZTE i ka makahiki 2018 a me Huawei i hala koke aku nei, ke hopohopo nui nei nā mea lawelawe ma nā wahi me ka nui o nā pahu i uhi ʻole ʻia (nā mea kūʻai aku ʻaʻole kūloko) i ka lako lako. ʻO ka hopena, ke nānā nei nā mea lawelawe e hoʻemi i ka pilikia ma ka hōʻemi ʻana i ka hilinaʻi ʻana i kekahi mea hoʻolako a me ka hoʻonui ʻana i ka noʻonoʻo ʻana i nā mea hoʻolako kūloko. Ma nā ʻano he nui, he mea maikaʻi kēia no nā ʻoihana liʻiliʻi e noho ana 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 palena ʻana i ka pilikia, e hoʻomau paha nā mea lawelawe nui loa i ke kūʻai ʻana i ka hapa nui o nā lako mai nā mea hana DWDM nui i loaʻa ka unahi a me ka ʻenehana e kākoʻo i kā lākou mau hana i ka wā e hiki mai ana.
Ke Kūlana Hoʻoikaika o ka ʻOihana
ʻO ke ala maikaʻi loa paha e wehewehe ai i ke kūlana o ka ʻoihana lako WDM optical i kēia makahiki, ʻo ia ka "dynamic." Ke ʻōlelo nei au i kēia no ka mea, ʻaʻole like me ka wā ma mua i ka wā i like like ai nā mana o ka ʻoihana mai kēlā makahiki a kēia makahiki, ua puka mai nā mana hou i ka ʻoihana optical i kēia makahiki e hiki ke hoʻololi hou iā ia. ʻO ke kikoʻī, ʻo nā mana hou aʻu e kuhikuhi nei, ʻo ia ka hiki ke kiʻekiʻe o ka hoʻololi huahana me IPoDWDM i hoʻāla ʻia e 400ZR i loko o kahi plug QSFP-DD a me kahi hoʻololi i ke ʻano o ka mea kūʻai aku i hana ʻia e nā hana a ke aupuni US ma nā mea hana Kina i hiki ke hoʻololi i ke ʻano o ka mea kūʻai aku ma kekahi mau wahi i ka hala ʻana o ka manawa.
