Ko te whakareatanga wehewehenga ngaru whatu he hangarau e tuku ana i ngā tohu whatu maha-roa-ngaru ki roto i te muka whatu kotahi. Ko te kaupapa matua ko te whakakotahi (whakarea) i ngā tohu whatu o ngā roangaru rerekē i te pito tuku, ka honoa ki te muka whatu kotahi i runga i te raina taura whatu hei tuku, ka wehea (whakarea) ngā tohu whatu o ngā roangaru kua whakakotahihia i te pito whiwhi. , ā, ka tukatukahia anō, ka whakahokia mai te tohu taketake ka tukuna ki ngā pito rerekē.
Ehara i te ariā hou te whakareatanga wehenga roangaru WDM. I te tīmatanga o te putanga mai o te whakawhitiwhiti kōrero muka whatu, i mōhio te iwi ka taea te whakamahi i te whānuitanga nui o te muka whatu mō te tuku whakareatanga roangaru, engari i mua i te tekau tau atu i 1990, kāore i kitea he whanaketanga nui i roto i tēnei hangarau. Te whanaketanga tere Mai i te 155Mbit/s ki te 622Mbit/s ki te 2.5Gbit/s Kua piki ake te tere TDM pūnaha i ngā tau kua pahure ake nei. Kāore i te maha ngā tāngata e aro ki tētahi atu hangarau ina tere haere tētahi hangarau. I te tau 1995 pea. Ko tētahi take nui mō te huringa i roto i te whanaketanga o te pūnaha WDM ko te mea i pāngia te iwi e ngā ngoikoretanga i roto i te hangarau TDM 10Gbit/s i taua wā, ā, he maha ngā kanohi i aro ki te whakareatanga me te tukatuka i ngā tohu whatu. I taua wā tonu ka whānuitia ngā tono o te pūnaha WDM puta noa i te ao.
