SONET (Whatunga Whatu Tukutahi)
He paerewa tuku whatunga tere-teitei a SONET i te Hononga o Amerika. Ka whakamahia e ia te muka whatu hei reo tuku hei tuku i ngā mōhiohio matihiko i roto i te tahora mowhiti, i te tahora pūwāhi-ki-pūwāhi rānei. I tōna pūtake, ka tukutahi i ngā rerenga mōhiohio kia taea ai te whakarea i ngā tohu mai i ngā pūtake rerekē i runga i te ara tohu noa tere-teitei. Ka tohuhia a SONET e ngā taumata OC (kawe whatu), pērā i te OC-3, OC-12, OC-48, me ētahi atu, ko ngā tau e tohu ana i ngā whakarea o te waeine taketake OC-1 (51.84 Mbps). Kua hangaia te hoahoa SONET me te kaha tiaki me ngā āheinga whakaora-ake, nō reira he maha ngā wā e whakamahia ana i roto i ngā whatunga tuarā.
SDH (Te Aromatawai Mamati Tukutahi)
Ko te SDH te rite o te SONET o te ao, e whakamahia ana i Ūropi me ētahi atu rohe ehara i te US. Ka whakamahia e te SDH ngā taumata STM (Synchronous Transport Module) hei tautuhi i ngā tere tuku rerekē, pērā i te STM-1, STM-4, STM-16, me ētahi atu, ko te STM-1 he ōrite ki te 155.52 Mbps. He maha ngā taipitopito hangarau e taea ai te mahi tahi a te SDH me te SONET, engari he nui ake te ngāwari o te SDH, pērā i te tuku i ngā tohu mai i ngā pūtake maha kia ngāwari ake te whakauru ki roto i te muka whatu kotahi.
DWDM (Whakareatanga Wehenga Roangaru Kikī)
Ko te DWDM he hangarau tuku whatunga muka whatu e whakanui ana i te whānui o te whatunga mā te tuku i ngā tohu whatu maha o ngā roangaru rerekē i te wā kotahi i runga i te muka whatu kotahi. Ka taea e ngā pūnaha DWDM te kawe i te neke atu i te 100 tohu o ngā roangaru rerekē, ia o ēnei ka taea te kī he hongere motuhake, ā, ka taea e ia hongere te tuku i ngā tere me ngā momo raraunga rerekē. Mā te whakamahinga o te DWDM ka taea e ngā kaiwhakahaere whatunga te whakawhānui ake i te kaha o te whatunga me te kore e whakatakoto taura whatu hou, he mea tino nui tēnei mō te mākete ratonga raraunga me te tipu tere o te tono.
Ngā rerekētanga i waenga i ngā mea e toru
Ahakoa he rite te ariā o ngā hangarau e toru, he rerekē tonu te whakamahinga tūturu:
Ngā Paerewa Hangarau: Ko te SONET me te SDH ngā paerewa hangarau hototahi e rua. Ko te SONET te nuinga o te wā e whakamahia ana i Amerika Te Raki, ko te SDH ia e whakamahia whānuitia ana i ētahi atu rohe. Ko te DWDM he hangarau whakarea roangaru e whakamahia ana mō te tuku i ngā tohu whakarara maha, kaua ki ngā paerewa hōputu raraunga.
Te tere raraunga: Ka tautuhia e SONET me SDH ngā wāhanga tere pumau mō te tuku raraunga mā roto i ngā taumata, i ngā kōwae rānei, ko te DWDM ia e arotahi ana ki te whakanui ake i te tere tuku raraunga whānui mā te tāpiri i ngā hongere tuku ki roto i te muka whatu kotahi.
Ngāwari me te tauine: He nui ake te ngāwari o te SDH i te SONET, e whakahaere ana i ngā whakawhitiwhitinga ā-ao, engari he nui te ngāwari me te tauine o te tere raraunga me te whakamahinga o te whānuitanga raraunga nā te hangarau DWDM, e āhei ai te whatunga ki te whānui haere i te tipu haere o te tono.
Ngā Wāhi Whakamahinga: He maha ngā wā ka whakamahia a SONET me SDH hei hanga whatunga tuara me ā rātou pūnaha tiaki me te whakaora-ake, ko te DWDM ia he otinga mō te tuku whatunga whatu tawhiti me te tawhiti-tino-roa, e whakamahia ana mō ngā hononga i waenga i ngā pokapū raraunga, i waenga rānei i ngā pūnaha taura ruku moana, me ētahi atu.
Hei whakarāpopototanga, ko SONET, SDH me DWDM ngā hangarau matua mō te hanga whatunga whakawhitiwhiti muka whatu o ēnei rā me ngā mea kei te heke mai, ā, he āhuatanga tono motuhake me ngā painga hangarau tō ia hangarau. Mā te whiriwhiri me te whakatinana tika i ēnei hangarau rerekē, ka taea e ngā kaiwhakahaere whatunga te hanga whatunga tuku raraunga whai hua, pono, me te tere-teitei huri noa i te ao.
Ka kawea mai e mātou ā mātou hua DWDM me DCI BOX ki te haere ki te Hakari Hangarau o Āwherika, ko ngā taipitopito e whai ake nei:
Ko te tūru nama ko D91A,
Te Rā: 12 ki te 14 o Noema, 2024.
Tāpiri: Te Pokapū Huihuinga ā-Ao o Cape Town (CTICC)
Ko te tumanako ka kite i a koe i reira!
