Ko te OXC (whatu hononga-whiti) he putanga whanaketanga o te ROADM (Reconfigurable Optical Add-Drop Multiplexer).
Hei te kaupapa matua o te whakawhiti whatunga whatu, ko te kaha ki te whakawhanui me te whai hua o ngā hononga whakawhiti whatu (OXC) ehara i te mea ka whakatau noa i te ngāwari o ngā āhua whatunga engari ka pā tika hoki ki ngā utu hanga me te whakahaere me te tiaki i ngā whatunga whatu nui. He rerekē ngā momo OXC rerekē i roto i te hoahoa hoahoa me te whakatinanatanga mahi.
Kei te whakaahua i raro nei te hoahoa tuku iho a te CDC-OXC (Colourless Directionless Contentionless Optical Cross-Connect), e whakamahi ana i ngā pana whiriwhiri roangaru (WSS). I te taha raina, ko ngā WSS 1 × N me N × 1 e mahi ana hei waeine tomo/putanga, ko ngā WSS M × K i te taha tāpiri/taka e whakahaere ana i te tāpiri me te taka o ngā roangaru. Ka honoa ēnei waeine mā roto i ngā muka whatu i roto i te papa tuara OXC.

Ka taea hoki tēnei mā te huri i te papa muri ki te whatunga Spanke, ka hua ake ko tā mātou hoahoanga Spanke-OXC.
Pikitia: Hanganga Spanke-OXC
E whakaatu ana te ahua i runga ake nei, i te taha rārangi, e hono ana te OXC ki ngā momo tauranga e rua: ngā tauranga ahunga me ngā tauranga muka. E rite ana ia tauranga ahunga ki te ahunga matawhenua o te OXC i roto i te āhua whatunga, ko ia tauranga muka e tohu ana i te takirua muka ahunga-rua i roto i te tauranga ahunga. Kei roto i te tauranga ahunga he maha ngā takirua muka ahunga-rua (arā, he maha ngā tauranga muka).
Ahakoa ka tutuki i te OXC e ahu mai ana i Spanke te whakawhiti kore-aukati mā te hoahoa papa-muri e hono katoa ana, ka nui haere te nui o ōna herenga i te pikinga ake o te rere o te whatunga. Ko te rohe tatau tauranga o ngā pana whiriwhiri roangaru arumoni (WSS) (hei tauira, ko te mōrahi e tautokona ana i nāianei ko te 1×48 tauranga, pērā i te FlexGrid Twin 1×48 a Finisar) ko te tikanga ko te whakawhānui i te taha OXC me whakakapi i ngā taputapu katoa, he utu nui tēnei, ā, ka ārai i te whakamahinga anō o ngā taputapu o nāianei.
Ahakoa he hoahoa OXC ahu-teitei e hangai ana ki ngā whatunga Clos, e whakawhirinaki tonu ana ki ngā WSS M×N utu nui, ā, he uaua ki te whakatutuki i ngā whakaritenga whakapai ake.
Hei whakatika i tēnei wero, kua whakaarohia e ngā kairangahau tētahi hoahoa ranu hou: HMWC-OXC (Hybrid MEMS and WSS Clos Network). Mā te whakauru i ngā pūnaha hiko-iti (MEMS) me te WSS, ka mau tonu te mahi tata-kore-ārai a tēnei hoahoa, me te tautoko anō hoki i ngā āheinga "utu-i-te-tipu", e whakarato ana i tētahi ara whakapai ake utu-whai hua mō ngā kaiwhakahaere whatunga whatu.
Ko te hoahoa matua o te HMWC-OXC kei roto i tōna hanganga whatunga Clos paparanga-toru.
Pikitia: Hanganga Spanke-OXC i runga i ngā Whatunga HMWC
Ka whakatinanahia ngā pana whatu MEMS teitei-ahu ki ngā paparanga whakauru me te putanga, pērā i te tauine 512×512 e tautokona ana e te hangarau o nāianei, hei hanga i tētahi puna tauranga nui-kaha. Ko te paparanga waenga he maha ngā kōwae Spanke-OXC iti ake, e honoa ana mā roto i ngā "tauranga-T" hei whakamama i te pupūtanga o roto.
I te wāhanga tuatahi, ka taea e ngā kaiwhakahaere te hanga i te hanganga i runga i te Spanke-OXC o nāianei (hei tauira, te tauine 4×4), mā te whakamahi noa i ngā pana MEMS (hei tauira, 32×32) ki ngā paparanga whakauru me te putanga, me te pupuri tonu i tētahi kōwae Spanke-OXC kotahi i te paparanga waenga (i tēnei take, he kore te maha o ngā tauranga-T). I te pikinga ake o ngā whakaritenga kaha whatunga, ka tāpirihia mārire ngā kōwae Spanke-OXC hou ki te paparanga waenga, ā, ka whirihorahia ngā tauranga-T hei hono i ngā kōwae.
Hei tauira, ina whakawhanuitia te maha o ngā kōwae paparanga waenga mai i te kotahi ki te rua, ka whakatakotoria te maha o ngā tauranga-T ki te kotahi, ka piki ake te whānuitanga katoa mai i te whā ki te ono.
Pikitia: Tauira HMWC-OXC
Ka whai tēnei tukanga i te herenga tawhā M > N × (S − T), arā:
Ko M te maha o ngā tauranga MEMS,
Ko N te maha o ngā kōwae paparanga waenga,
Ko S te maha o ngā tauranga i roto i te Spanke-OXC kotahi, ā
Ko T te maha o ngā tauranga honohono.
Mā te whakarerekētanga hihiri i ēnei tawhā, ka taea e te HMWC-OXC te tautoko i te whānui haere mai i te tauine tīmatanga ki te whānuitanga ūnga (hei tauira, 64×64) me te kore e whakakapi i ngā rauemi taputapu katoa i te wā kotahi.
Hei manatoko i te mahi tuturu o tēnei hoahoanga, i whakahaerehia e te tīma rangahau ngā whakamātautau whakatauira i runga i ngā tono ara whatu hihiri.
Pikitia: Te Mahi Ārai o te Whatunga HMWC
Ka whakamahia e te whakatauira he tauira waka Erlang, me te whakaaro ka whai ngā tono ratonga i te tohatoha Poisson, ā, ka whai ngā wā pupuri ratonga i te tohatoha taupū kino. Kua whakatakotoria te kawenga waka katoa ki te 3100 Erlangs. Ko te whānuitanga OXC e whai ana ko te 64×64, ā, ko te tauine MEMS paparanga tāuru me te tāuru ko te 64×64 hoki. Kei roto i ngā whirihoranga kōwae Spanke-OXC paparanga waenga ngā whakaritenga 32×32, 48×48 rānei. Ko te maha o ngā tauranga-T kei waenga i te 0 ki te 16 i runga i ngā whakaritenga o te horopaki.
E whakaatu ana ngā hua, i roto i te horopaki me te ahunga o te D = 4, ko te tūponotanga aukati o te HMWC-OXC he tata ki te tūāpapa Spanke-OXC tuku iho (S(64,4)). Hei tauira, mā te whakamahi i te whirihoranga v(64,2,32,0,4), ka piki ake te tūponotanga aukati mā te 5% noa iho i raro i te kawenga taurite. Ina piki ake te ahunga o te D = 8, ka piki ake te tūponotanga aukati nā te "pānga o te pūtake" me te hekenga o te roa o te muka i ia ahunga. Heoi, ka taea te whakaiti i tēnei take mā te whakanui ake i te maha o ngā tauranga-T (hei tauira, te whirihoranga v(64,2,48,16,8)).
He mea nui, ahakoa ka taea e te tāpiri o ngā kōwae paparanga-waenga te aukati i roto nā te tautohetohe T-port, ka taea tonu e te hoahoanga whānui te whakatutuki i te mahi tino pai mā te whirihoranga tika.
E whakaatu ana te tātaritanga utu i ngā painga o te HMWC-OXC, e whakaaturia ana i te pikitia i raro nei.
Pikitia: Te Tūponotanga Ārai me te Utu o ngā Hanganga OXC Rerekē
I roto i ngā horopaki kiato-teitei me te 80 ngā roangaru/muka, ka taea e te HMWC-OXC (v(64,2,44,12,64)) te whakaiti i ngā utu mā te 40% ki te whakataurite ki te Spanke-OXC tuku iho. I roto i ngā horopaki roangaru-iti (hei tauira, 50 ngā roangaru/muka), he nui ake te painga utu nā te whakaiti i te maha o ngā tauranga-T e hiahiatia ana (hei tauira, v(64,2,36,4,64)).
I ahu mai tēnei painga ōhanga i te whakakotahitanga o te kiato tauranga teitei o ngā pana MEMS me te rautaki whakawhānui modular, e kore e karo noa i te utu o te whakakapinga WSS tauine nui engari ka whakaitihia hoki ngā utu piki haere mā te whakamahi anō i ngā kōwae Spanke-OXC o nāianei. E whakaatu ana hoki ngā hua whakatauira mā te whakarerekē i te maha o ngā kōwae paparanga-waenga me te ōwehenga o ngā tauranga-T, ka taea e te HMWC-OXC te whakataurite i te mahi me te utu i raro i ngā whirihoranga kaha me te ahunga o ngā roangaru rerekē, ka whakarato i ngā whai wāhitanga arotau maha-ahu ki ngā kaiwhakahaere.
Ka taea e ngā rangahau ā muri ake nei te tūhura atu i ngā rauropi tohatoha tauranga-T hihiri hei arotau i te whakamahinga rauemi ā-roto. Hei tāpiri, me ngā whanaketanga o ngā tukanga hanga MEMS, mā te whakaurunga o ngā pana-ahu teitei ake ka whakarei ake i te tauine o tēnei hoahoa. Mō ngā kaiwhakahaere whatunga whatu, he tino pai tēnei hoahoa mō ngā horopaki me te tipu haere o ngā waka kāore i te tino mārama, e whakarato ana i tētahi otinga hangarau whai hua mō te hanga i tētahi whatunga tuara whatu-katoa pakari me te tauine.
