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 o te 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 o runga. 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 hoahoa 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.
