Ko te "tino whakataetae" te huarahi pai ki te whakaahua i te mākete taputapu Optical Transport DWDM. Ahakoa he mākete nui, e $15 piriona te taumaha, e 20 pea ngā kaihanga pūnaha e whai wāhi kaha ana ki te hoko taputapu DWDM me te whakataetae kaha mō te wāhi mākete. Heoi anō, e whitu anake ngā kaihoko e pupuri ana i te 90 ōrau o te mākete, e 10 ōrau anake mō ngā kaihoko e toe ana, ā, ahakoa i roto i ngā kaihoko e whitu o runga, he nui te rohenga wāhi mākete—25 ōrau i waenga i te kaihoko nui rawa me te kaihoko iti rawa.
Ko te tauine me te haumitanga o te kamupene tētahi o ngā mea nui e wehewehe ana i te mākete, i roto i ngā kaihoko matua, i waho atu i a FiberHome, kua haumi katoa ki te whakaurunga poutū i runga i ngā wāhanga taha-raina pērā i te DSP honohono me te pito mua whatu. Kāore e nui te whakaaro mēnā kei runga i te pito mua whatu te pito mua Silicon Photonics (SiPh) Indium Phosphide (InP) rānei, ahakoa kei te tautohetohe tonu ngā tohunga ahumahi mō ngā hangarau e rua. Ko te mea nui ko te whakawhanaketanga a te kamupene i tētahi hangarau ā-roto e wehewehe ana i ngā hua mai i ētahi atu, e whakaiti ana i ngā utu o āna hua, ā, e hoatu ana ki te kamupene he wā pai ake ki te mākete. Hei tāpiri, nā te mea he nui te tauine me ngā rauemi e hiahiatia ana (te moni, te tangata, me te taonga hinengaro) hei whakawhanake i ēnei wāhanga, ka hangaia e te whakaurunga poutū he arai ki ngā tāngata hou (tae atu ki ngā tāngata tawhito).
Kei te wātea te whakakapinga hua
Pērā i te nuinga o ngā ahumahi, ko te kaha o waho ki te umanga Waka Whatu ko te whakakapinga hua. Ahakoa kāore i te tino riri te whakakapinga hua i ngā tekau tau kua pahure ake nei, nā ngā painga o te mahi me te utu o te hangarau DWDM me ngā here taumata-pūnaha ki te whakauru i te hangarau DWDM ki tētahi tūāpapa tata, kei te tīmata te huri haere o te tai me ngā whatu mono iti 400ZR. Nā te hua o ēnei whatu mono hou i roto i te momo QSFP-DD ka taea te tuku i ngā roangaru 400 Gbps tae atu ki te 120 kiromita, e matapaetia ana e mātou he hiahia nui ki te IP-over-DWDM (IPoDWDM), he hoahoa pūnaha e whakauru ana i ngā whatu DWDM ki roto i tētahi Whakawhiti Ethernet, i tētahi Pouara rānei. Mā tēnei, me te kore e kī, ka piki ake te taumata o te whakataetae i roto i te wāhi taputapu DWDM i te mea ka whakatau ngā kiritaki i waenga i te whakamahi i tētahi pūnaha DWDM tuku iho mai i ā mātou kaihoko DWDM 20, i tētahi pūnaha IPoDWDM rānei mai i ētahi atu kaihoko whakawhiti. (Ko ngā kaihoko Whakawhiti Ethernet me te Pouara matua ko Arista, Cisco, Juniper, me Nokia).
Heoi, ka whai hua anō hoki te 400ZR ki ngā kaihoko DWDM whatu. Ko tētahi take, kāore ngā kaiwhakahaere katoa e hiahia ki te huri i tā rātou whatunga ki te IPoDWDM, ā, ka whiriwhiri rātou ki te whakamahi i ngā whatu mono 400ZR i runga i te pūnaha DWDM, me te pupuri i te hanganga whatunga kia kaua e rerekē, me te whai hua anō hoki i te utu iti o ngā whatu 400ZR. Engari ko tētahi atu take, he hangarau honohono te 400ZR, nō reira, kei te pai te tūnga o ngā kamupene kua haumi ki tēnei hangarau i roto i te tekau tau kua hipa ki te aro atu ki tēnei whai wāhitanga hou. Nō reira, ko te nuinga o ngā kaihanga o ngā whatu mono 400ZR he kamupene kua roa nei e whakawhanake ana i ngā pūnaha DWDM honohono, pērā i a Ciena, Cisco, me Nokia. I whakaaro a Huawei ki te whakawhanake i tētahi 400ZR anō hoki, engari kāore mātou i te tino mōhio mēnā ka whakaroahia tēnei mahi e ngā here a te US ki te kamupene.
E pai ake ana ngā kaihoko ki ngā kaiwhakarato ā-rohe ina wātea ana
I ētahi wā, ehara tēnei i te mea tawhito, ehara hoki i te mea hou, engari he mea nui kia whakahuatia anō ko te nuinga o te wā, he pai ake ki ngā kaihoko te hoko taputapu mai i tētahi kaiwhakarato ā-rohe. I roto i tēnei tūtohi, ka wehea te mākete taputapu DWDM o te ao ki ngā rohe nui me ngā kaihoko e tuku ana i tētahi rohe. Ko te rahi o te pouaka e whakaatu ana i te hea o te kaihoko i taua rohe, ā, ko ngā pouaka atarangi matomato ko ngā kaihoko e kiia ana he kāinga ki taua rohe. Ehara i te mea miharo i roto i ngā rohe e rua—Amerika Te Raki me Haina—kei reira he maha ngā kaihoko ā-rohe, ko te nui o ngā hoko DWDM ka tukuna ki ēnei kamupene ā-rohe. Nā te nui o te ranunga o ngā kamupene i roto i ngā "ētahi atu," kāore au i whakamarumaru i aua pouaka, engari i Amerika Te Raki me Haina ko te nuinga o ngā "ētahi atu" he kamupene ā-rohe anō hoki.
Ko te mea pea e pārekareka ana ko ngā pouaka kāore i te atarangi. Ko te take, i muri i te whakatakoto here a te US ki a ZTE i te tau 2018 me Huawei i ēnei rā tata nei, kei te piki haere te aro o ngā kaiwhakarato ratonga i ngā rohe he nui ngā pouaka kāore i te atarangi (ngā kaihoko ehara i te kāinga) ki te tuku taputapu. Nō reira, kei te titiro ngā kaiwhakarato ratonga ki te whakaiti i te mōrearea mā te whakaiti i te whakawhirinaki ki tētahi kaiwhakarato me te whakanui ake i te whakaaro ki ngā kaiwhakarato ā-rohe. I roto i ngā huarahi maha, ka pai tēnei mō ngā kamupene iti kei ngā rohe ā-rohe pērā i a Tejas i Inia, Padtec i CALA, me PacketLight i EMEA. Heoi, i roto i te huarahi o te whakawhāiti i te mōrearea, tera pea ka haere tonu ngā kaiwhakarato ratonga nui ki te hoko i te nuinga o ngā taputapu mai i ngā kaihanga DWDM nui ake kei a rātou te tauine me te hangarau hei tautoko i ā rātou mahi ā muri ake nei.
Te Āhua Hihiri o te Ahumahi
Ko te huarahi pai pea ki te whakaahua i te āhua o te umanga taputapu WDM whatu i tēnei tau ko te "hihiri." E kī ana ahau i tēnei nā te mea kāore i rite ki ngā wā o mua i te wā i rite tonu ai ngā kaha o te umanga i ia tau, i puta ake ngā kaha hou i roto i te umanga whatu i tēnei tau ka taea te huri i tōna āhua. Ina koa, ko ngā kaha hou e kōrerohia ana e au ko te kaha ake o te whakakapinga hua me te IPoDWDM e whakahohea ana e te 400ZR i roto i te mono QSFP-DD me te huringa o te whanonga kiritaki i hangaia e ngā mahi a te kāwanatanga o Amerika ki ngā kaihanga Hainamana i taea ai te whakarerekē i te whenua kaihoko i ētahi rohe i roto i te wā.
