I te tere o te whanaketanga o te hangarau matauranga horihori (AI), kua eke te hiahia mō te tukatuka raraunga me te kaha whakawhitiwhiti kōrero ki tētahi taumata kāore i kitea i mua. Ina koa i ngā mara pēnei i te tātari raraunga nui, te ako hohonu, me te rorohiko kapua, he nui haere ngā whakaritenga mō ngā pūnaha whakawhitiwhiti kōrero mō te tere teitei me te whānui whānui. Ka pāngia te muka aratau kotahi tuku iho (SMF) e te rohe Shannon kore-raina, ā, ka eke tōna kaha tuku ki tōna rohe teitei. Ko te hangarau tuku Spatial Division Multiplexing (SDM), e tohuhia ana e te muka maha-matua (MCF), kua whakamahia whānuitia i roto i ngā whatunga tuku honohono tawhiti roa me ngā whatunga urunga whatu tawhiti poto, ka whakapai ake i te kaha tuku whānui o te whatunga.
Mā te whakauru i ngā matua muka motuhake maha ki roto i te muka kotahi, ka pakaruhia e ngā muka whatu maha-matua ngā herenga o ngā muka aratau-kotahi tuku iho, ka nui ake te kaha tuku. Tērā pea kei roto i te muka maha-matua e whā ki te waru ngā matua muka aratau-kotahi kua tohatohahia kia ōrite i roto i te hipoki tiaki me te diameter o te 125um pea, ka nui ake te kaha whānui o te whānui me te kore e whakanui ake i te diameter o waho, ka whakarato i te otinga pai hei whakatutuki i te tipu tere o ngā tono whakawhitiwhiti kōrero i roto i te matauranga horihori.
Ko te whakamahinga o ngā muka whatu maha-matua me whakaoti i ngā raruraru maha pēnei i te hononga muka maha-matua me te hononga i waenga i ngā muka maha-matua me ngā muka tuku iho. He mea tika kia whakawhanakehia ngā hua wāhanga e pā ana ki te taha pēnei i ngā hononga muka MCF, ngā taputapu hau whakauru me te hau whakaputa mō te tahuritanga MCF-SCF, ā, me whakaaro ki te hototahitanga me te whānui ki ngā hangarau o nāianei me ngā hangarau arumoni.
Pūrere pā hau maha-matua
Me pēhea te hono i ngā muka whatu maha-matua ki ngā muka whatu kotahi-matua tuku iho? Ko ngā taputapu muka maha-matua pā ki roto, ki waho (FIFO) he wāhanga matua mō te whakatutuki i te hononga whai hua i waenga i ngā muka maha-matua me ngā muka aratau kotahi paerewa. I tēnei wā, he maha ngā hangarau hei whakatinana i ngā taputapu muka maha-matua pā ki roto, ki waho: te hangarau whakarara hanumi, te tikanga paihere muka paihere, te hangarau arataki ngaru 3D, me te hangarau whatu ātea. He painga motuhake ō ngā tikanga o runga ake nei, ā, he pai mō ngā horopaki tono rerekē.
Hononga muka whatu MCF maha-matua
Kua ea te raruraru hononga i waenga i ngā muka whatu maha-matua me ngā muka whatu kotahi-matua, engari me ea tonu te hononga i waenga i ngā muka whatu maha-matua. I tēnei wā, ko te nuinga o ngā muka whatu maha-matua ka honoa mā te honohono hanumi, engari he iti anō hoki ngā herenga o tēnei tikanga, pērā i te uaua o te hanga me te uaua o te tiaki i te wāhanga o muri mai. I tēnei wā, kāore he paerewa kotahi mō te hanga muka whatu maha-matua. Ka hangaia e ia kaihanga ngā muka whatu maha-matua me ngā whakaritenga matua rerekē, ngā rahi matua, te mokowā matua, me ētahi atu, e whakanui ana i te uaua o te honohono hanumi i waenga i ngā muka whatu maha-matua.
Kōwae ranu MCF muka matua maha (e whakamahia ana ki te pūnaha whakakaha whatu EDFA)
I roto i te pūnaha tuku whatu Space Division Multiplexing (SDM), ko te kī ki te whakatutuki i te tuku kaha-teitei, tere-nui, me te tawhiti-roa kei roto i te utu mō te ngaronga tuku o ngā tohu i roto i ngā muka whatu, ā, ko ngā whakakaha whatu he wāhanga matua nui i roto i tēnei tukanga. Hei kaha nui mō te tono mahi a te hangarau SDM, ko te mahi a ngā whakakaha muka SDM te mea tika hei whakatau i te whaihua o te pūnaha katoa. I roto i ēnei, kua noho te whakakaha muka maha-matua erbium-doped (MC-EFA) hei wāhanga matua nui i roto i ngā pūnaha tuku SDM.
Ko te pūnaha EDFA noa he mea hanga mai i ngā wāhanga matua pēnei i te muka erbium-doped (EDF), te pūtake rama papu, te hononga, te wehewehe, me te tātari whatu. I roto i ngā pūnaha MC-EFA, kia tutuki ai te huringa whai hua i waenga i te muka maha-matua (MCF) me te muka matua kotahi (SCF), ka whakauruhia e te pūnaha ngā taputapu Fan in/Fan out (FIFO). Ko te otinga muka maha-matua EDFA a meake nei e tumanakohia ana ka whakauru tika i te mahi huringa MCF-SCF ki roto i ngā wāhanga whatu e pā ana (pēnei i te 980/1550 WDM, te tātari whakawhāiti whiwhinga GFF), mā te reira ka whakangawari i te hoahoanga pūnaha me te whakapai ake i te mahi whānui.
I te whanaketanga tonu o te hangarau SDM, ka whakaratohia e ngā wāhanga MCF Hybrid ngā otinga whakakaha kaha ake, iti iho hoki te ngaronga mō ngā pūnaha whakawhitiwhiti whatu kaha-nui a meake nei.
I roto i tēnei horopaki, kua whakawhanakehia e HYC ngā hononga muka whatu MCF i hangaia mō ngā hononga muka whatu maha-matua, me ngā momo atanga e toru: momo LC, momo FC, me te momo MC. Kua whakarerekētia te momo LC me te momo FC MCF maha-matua, ā, kua hoahoatia i runga i ngā hononga LC/FC tuku iho, e arotau ana i te mahi tūnga me te pupuri, e whakapai ake ana i te tukanga hononga huri, e whakarite ana i te iti o ngā huringa o te ngaronga whakaurunga i muri i ngā hononga maha, me te whakakapi tika i ngā tukanga honohono whakakotahi utu nui hei whakarite i te ngāwari o te whakamahi. Hei tāpiri, kua hangaia hoki e Yiyuantong he hononga MC motuhake, he iti ake te rahi i ngā hononga momo atanga tuku iho, ā, ka taea te whakamahi ki ngā wāhi matotoru ake.
