OTN me PTN
Me kī he rerekē rawa ngā hangarau o OTN me PTN, ā, i te taha hangarau, me kī kāore he hononga.
He whatunga kawe whatu te OTN, i ahu mai i te hangarau wehewehe roangaru tuku iho. Ko te nuinga o te wā ka tāpirihia e ia te mahi whakawhiti whatu mohio. Ka taea e ia te whakatutuki i te whakawhiti whatu mā te whirihoranga raraunga me te kore e pekepeke muka ā-ringa. Kua tino pai ake te tiaki me te ngāwari o te whatunga o ngā taputapu WDM. I taua wā anō, kei te whanake haere te whatunga OTN hou ki te whānui ake o te whānui, ngā matūriki nui ake, me te tiaki kaha ake.

He whatunga kawe mōkihi te PTN, he hua o te whakaurunga o te whatunga kawe me te whatunga raraunga. Ko te kawa matua ko te TMPLS, he iti ake ngā paparanga IP me ngā mōkihi o runga ake i ngā taputapu whatunga. Ka taea e ia te whakatutuki i te whatunga mowhiti me te tiaki. He whatunga raraunga akomanga-kaikawe (kāore e taea e ngā whatunga raraunga tuku iho te whakatutuki i ngā whakaritenga akomanga-kaikawe). He iti ake te whānui o te tuku o te PTN i tō te OTN. I te nuinga o te wā, ko te whānui mōrahi o te rōpū o te PTN he 10G, ko te ngaru kotahi OTN he 10G, ka taea e te ara rōpū te tae ki te 400G-1600G, ā, ka taea e te hangarau hou te tae ki te ngaru kotahi 40G. Koinei te pou tuara o te whatunga tuku.

OTN me SDH, WDM

Ko te OTN e hangai ana ki te hangarau WDM, ko ngā āheinga whakahaere, tiaki, whakahaere me te tuku (OAM) kaha o te SDH e whakaurua ana i runga i te kaha tuku tino nui. Ka whakamahia e te OTN te FEC paerewa kua whakauruhia, he nui ngā utu tiaki me te whakahaere, ā, he pai mō te waehere whakatika hapa FEC urunga ratonga nui-rahi, e whakapai ake ana i te mahi hapa moka me te whakanui ake i te whānuitanga o te tuku whatu.

Ngā horopaki tono OTN

Mā te whatunga whatu atamai e hangai ana ki te OTN ka whakaratohia he otinga tino pai mō te tuku ratonga whānui whānui. Ko te whatunga kawe matua ko te whatunga kawe matua ā-rohe, te whatunga kawe matua ā-roto, me te whatunga kawe matua (ā-rohe). Ka taea te wehewehe anō i te whatunga kawe matua (ā-rohe) ki tētahi paparanga matua, he paparanga whakahiato me tētahi paparanga urunga. Ki te whakatauritea ki te SDH, ko te painga nui o te hangarau OTN ko te whakarato i te whakaritenga me te tuku i te whānui o te whānui o te whānui o te whānui. Nō reira, ko te whakamahi i te hangarau OTN i ngā paparanga whatunga rerekē ka whakawhirinaki ki te rahi o te whānui o te whānui o te ratonga whakaritenga matua. E ai ki te āhua o nāianei o te whatunga, ko ngā matūriki matua o te whakaritenga paparanga matua o te whatunga tuku matua ā-rohe, te whatunga tuku matua ā-roto me te whatunga tuku matua (ā-rohe) he Gb/s me runga ake. He pai ake te hanga hangarau OTN.
Mō te taumata whakahiato me te urunga o te whatunga kawe waka o te rohe tāone nui (ā-rohe), ina tae ngā matūriki whakaritenga matua ki te taumata Gb/s, ka taea hoki te hanga i te hangarau OTN mā te huarahi pai ake.

1. Whatunga kawe whatu matua ā-motu Nā te whatunga me ngā ratonga e hangai ana ki te IP, te whanaketanga o ngā ratonga hou me te tere pikinga o ngā kaiwhakamahi whānui, kua tino piki ake te rere o te IP i runga i te matua ā-motu, ā, kua piki ake te tono mō te whānui o te hononga i ia tau. Ka haria e te raina matua ā-motu WDM ngā ratonga tawhiti PSTN/2G, ngā ratonga tawhiti NGN/3G, me ngā ratonga raina matua ā-motu Ipurangi. Nā te nui o ngā ratonga kawe, he hiahia nui tō ngā raina matua ā-motu WDM ki te tiaki i ngā ratonga kawe. Whai muri i te whakamahi i te hangarau OTN, ka taea e te aratau kawe o te raina matua ā-motu IP i runga i te OTN te whakatutuki i te tiaki SNCP, te tiaki whatunga mowhiti rite ki te SDH, te tiaki whatunga MESH me ētahi atu tikanga tiaki whatunga. Kua tino heke.

2. Whatunga kawe whatu matua ā-rohe/ā-rohe Ka kawe ngā pouara tuara ā-rohe/ā-rohe i ngā ratonga i waenga i ngā tari tawhiti (NGN/3G/IPTV/raina motuhake mō ngā kiritaki nui, me ētahi atu). Mā te hanganga o te whatunga tuku whatu matua OTN ā-rohe/ā-rohe, ka taea te whakatutuki i te tuku haumaru me te pono o ngā ratonga GE/10GE, 2.5G/10GPOS nui-whānui; ka taea te hanga whatunga mowhiti, whatunga mowhiti matatini, me ngā whatunga MESH; ka taea te whakawhānui i te whatunga i runga i te tono; Te whakatutuki i te whakawhiti-whakarite me te whakapaipai i ngā ratonga roangaru/roanga-iti, me te whakarato ratonga raina motuhake roangaru/roanga-iti mō ngā kiritaki nui; te whakatutuki hoki i te tuku o ētahi atu ratonga pēnei i te STM-1/4/16/64SDH, ATM, FE, DVB, HDTV, ANY, me ētahi atu.

3. Whatunga kawe whatu o te rohe/rohe I te paparanga matua o te whatunga o te rohe, ka taea e te whatunga kawe whatu OTN te whakatutuki i ngā ratonga whānui i waenga i te pouara whakahiato o te rohe, te pouara whakahiato C4 (pokapū rohe/rohe) whatunga rohe me te pouara matua o te tāone nui. tuku. Ko te atanga whakarunga o te pouara ko te GE/10GE te nuinga, ā, tera pea he 2.5G/10GPOS. Ko te whatunga kawe whatu OTN i te pokapū o te rohe
