I roto i te rangahau me te whanaketanga o ngā hangarau muka whatu hou, kua aro nui te hunga ki te whakamahi i te SDM space division multiplexing. E rua ngā huarahi matua mō te whakamahinga o te SDM i roto i ngā muka whatu: te core division multiplexing (CDM), e tukuna ai te raraunga mā te matua o te muka whatu maha-matua. Te Mode Division Multiplexing rānei (MDM), e tuku ana mā ngā aratau horapa o te muka aratau-toru, maha-aratau rānei.
Ko te kaupapa matua o te muka Core Division Multiplexing (CDM) e hangai ana ki te whakamahinga o ngā kaupapa matua e rua.
Ko te tuatahi e hangai ana ki te whakamahinga o ngā paihere muka matua-kotahi (rīpene muka), e whakakotahitia ai ngā muka aratau-kotahi whakarara hei hanga paihere muka, rīpene rānei ka taea te whakarato i ngā rau hononga whakarara.
Ko te kōwhiringa tuarua e hangai ana ki te tuku raraunga mā runga i te matua kotahi (aratau kotahi mō ia matua) kua whakauruhia ki roto i te muka kotahi, arā, i roto i te muka maha-matua MCF. Ka whakaarohia ia matua he hongere kotahi motuhake.
Ko te muka MDM (Module Division Multiplexing) e pā ana ki te tuku raraunga mā roto i ngā momo muka whatu rerekē, ā, ka taea te kī he momo hongere motuhake ia momo.
Ko ngā momo MDM e rua e kitea whānuitia ana ko te muka aratau maha (MMF) me te muka aratau haurua (FMF). Ko te rerekētanga matua i waenga i ngā momo e rua ko te maha o ngā aratau (ngā hongere e wātea ana). Nā te mea ka taea e ngā MMF te tautoko i te maha o ngā aratau (ngā tekau aratau), ka nui haere te whakawhitiwhiti kōrero ā-roto me te whakaroa rōpū aratau rerekē (DMGD).
Kei reira anō te muka tioata whakaahua (PCF) e taea te kī nō tēnei momo. E hangai ana ki ngā āhuatanga o ngā tioata whakaahua, e aukati ana i te mārama mā te pānga āputa roopu, ā, e tuku ana mā te whakamahi i ngā kōhao hau i roto i tōna wāhanga whakawhiti. Ko te nuinga o te PCF he mea hanga mai i ngā rauemi pēnei i te SiO2, As2S3, me ētahi atu, ā, ka whakaurua ngā kōhao hau ki te rohe huri noa i te uho hei whakarerekē i te rerekētanga o te taupū whakaata i waenga i te uho me te whakakikorua.
Ka taea te whakaahua i te muka CDM hei tāpiri noa iho i ngā matua muka aratau-kotahi whakarara e kawe ana i ngā mōhiohio, kua whakauruhia ki roto i te whakakikorua kotahi (muka maha-matua MCF, paihere muka matua-kotahi rānei). Ko te whakareatanga wehenga aratau MDM ko te whakamahinga o ngā aratau ā-wāhi-whatu maha i roto i te reo tuku hei hongere raraunga takitahi/motuhake/motuhake, ko te tikanga mō te tuku hononga-tawhiti poto.
