I te taha o te tere o te whanaketanga o ngā hanganga whatunga, kei te piki haere te aro o te umanga whakawhitiwhiti kōrero ki tētahi arai nui mō te tipu. Ko tētahi o ngā hangarau matua o ngā whakawhitiwhiti kōrero whatu — te Wavelength Division Multiplexing (WDM) — kua waiho hei otinga matua mō te wikitoria i ēnei herenga ā-tinana.

Ki te whakaritea te muka whatu ki te huarahi tere, he rite te whakawhitiwhiti kōrero kotahi-ngaru tuku iho ki tētahi waka kotahi e noho ana i te huarahi katoa. Ko te hangarau WDM te tikanga ka wehea tēnei ara tinana kia maha ngā "ara mariko" kāore e whakararuraru (ngā roangaru whatu rerekē), ka taea ai te tuku i ngā tohu raraunga maha i te wā kotahi mā te muka kotahi. Ko te taputapu matua e āhei ai tēnei hangarau ko te tātari DWDM (Dense Wavelength Division Multiplexing) kore mahi. Ka whakaratohia e tēnei tuhinga he tātari poto mō tēnei hangarau.

I. Ngā Mātāpono Matua me ngā Painga o ngā Tātari Whakakorekore

Ko te tikanga o te kupu "korekore" kāore te taputapu e hiahia ki tētahi pūtake hiko o waho. Engari, ka whakawhirinaki katoa ki ngā paninga kiriata angiangi tika, ki ngā hanganga whatu rānei hei wehewehe tika (whakaiti-whakawhiti) hei whakakotahi rānei (whakanui-whakawhiti) i ngā tohu whatu o ngā roangaru rerekē.

Mā tēnei āhuatanga whatu tūturu ka tino pumau, ka pono hoki, ka tino ātete te taputapu ki te pokanoa hikohiko. Nō reira, he tino pai mō te whakamahinga roa i roto i ngā rūma taputapu waea uaua, i ngā taiao kino rānei o waho.

I roto i ngā hanganga whatunga whatu, ka mahi ngā tātari DWDM kore mahi hei "kaiwhakahaere waka." Ka whai pūmau rātou i ngā paerewa o te International Telecommunication Union (ITU-T), ka wehea te matapihi tuku whatu iti-ngaronga ki ngā tekau, ki ngā rau rānei o ngā hongere whakawhitiwhiti motuhake me te mokowā roangaru tino whaiti.

Ko te tikanga o tēnei, ka taea e te muka whatu kotahi, i te tīmatanga he kotahi noa te tohu e mau ana, te whakawhānui tonu i tōna kaha tuku kia maha ngā wā, ka tino whakapai ake i te pai o te hihi.

II. Ngā horopaki tono me te uara noa

Ko ēnei tātari kore mahi he mea hanga ki ngā hanganga takai paerewa, pērā i ngā kōwae rīpene LGX, ngā kāri whakairinga whatanga 19-inihi rānei, ā, he hononga muka whatu tino tika mō te whakaurunga maeneene ki ngā whatunga muka aratau-kotahi o nāianei. Ko ngā uara tono matua ko:

Te Whanuitanga o te Whatunga Tuku me te Whatunga Tuara o te Tāone Nui

Ki te kore e tāpirihia he taura muka tūturu hou, ka taea e te hangarau WDM te whakanui ake i te whānui o te tuku raraunga o ngā whatunga rohe tāone nui me ngā whatunga tuara rohe, kia tutuki ai ngā tono nui mō te tuku raraunga o ngā ratonga pēnei i te roma ataata whakamāramatanga-teitei me te rorohiko kapua.

Ngā Whatunga Whakatipu o Waho (OSP) me ngā Whatunga Uru

Nā ō rātou āhuatanga kore mahi, kore tiaki hoki, e whakamahia whānuitia ana ēnei taputapu ki ngā whatunga tohatoha whatu o waho, ā, ka whakaitihia ngā utu whakahaere me te tiaki mō te wā roa mō ngā kaiwhakahaere waea.

Hononga Pokapū Raraunga

I roto i ngā pokapū raraunga, i waenga rānei i ngā pokapū raraunga maha, ka taea e ngā tātari kore mahi te arahi i ngā tohu whatu maha me te iti rawa o te ngaronga whakaurunga, kia tere ai, kia pumau ai hoki te tuku raraunga.
