ngā hononga muka whatu/whakaheke wdm's & plc's
Kei rohe o te whakapāho iwi me te tuku rara moana, ko ngā kaiwhakawehi wehenga raupo pūtaiao, WDMs, me ngā PLC he momo hanganga matua. Ko te mahi tonu o enei taonga he wehewehi rānei, he whakaaetanga rānei i ngā pūrongo mōhuhinga ki roto i ngā tūmomo raupapa pūtaiao. He tino whakawehe i tētahi pūrongo katoa ki ētahi atu pūrongo e ai ki tētahi kaiwhakawehi raupapa pūtaiao, ahakoa ko te Wavelength Division Multiplexer (WDM) ka whakaae i ētahi pūrongo nui i waenganui i ngā haurangi ki runga i tētahi raupapa anake. Ko te take matua o te hunga PLC (Planar Lightwave Circuit) kei reira hei whai hua nui me te whakaū. Ko ngā āhuatanga hangarau matua he iti haere whakamahere, he nui whakaeke, me te pai rawa hoki te tūpato. Kua whakamahiia i runga i ngā whakapāho iwi, i ngā tohu whakaata, i te raupapa ki te whare, me ngā marae kōrero rara moana, whakamahia noa iho enei taonga hei wāhanga korekore o ngā whakapāho tuhinga o nāianei.
