I te nuinga o te wā, he taputapu te kaiwhakawhitiwhiti ka taea te tuku me te whiwhi tohu, ko te kaiwhakawhitiwhiti ia he wāhanga kua whakaritea tōna tukatuka hei aroturuki i ngā tohu e tae mai ana, ā, kua whakaritea ngā whakautu i mua i roto i ngā whatunga whakawhitiwhiti muka-whatu. Inaa, ko ngā kaiwhakawhitiwhiti ka tohuhia e tō rātou tere raraunga me te tawhiti mōrahi ka taea e te tohu te haere. He rerekē ngā kaiwhakawhitiwhiti me ngā kaiwhakawhitiwhiti, ā, kāore e taea te whakawhiti. E whakamārama ana tēnei tuhinga i te rerekētanga i waenga i ngā kaiwhakawhitiwhiti me ngā kaiwhakahoki.
Ngā Kaiwhakawhitiwhiti me ngā Kaiwhakawhitiwhiti: Ngā Whakamāramatanga
I roto i ngā whakawhitiwhitinga muka whatu, kua hangaia ngā kaiwhakawhitiwhiti whatu hei tuku me te whiwhi tohu whatu. Ko ngā kōwae kaiwhakawhitiwhiti e whakamahia whānuitia ana ko ngā taputapu I/O (whakauru/putanga) ka taea te whakawhiti wera, e mono ana ki ngā taputapu whatunga, pēnei i ngā pana whatunga, ngā tūmau, me ērā atu mea. He maha ngā momo kaiwhakawhitiwhiti whatu e whakamahia ana i roto i ngā pokapū raraunga, ngā whatunga hinonga, te rorohiko kapua, ngā pūnaha whatunga FTTX. He maha ngā momo kaiwhakawhitiwhiti, tae atu ki te 1G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 200G me te 400G anō hoki. Ka taea te whakamahi me ngā momo taura, taura parahi rānei mō te tuku tawhiti i roto i ngā whatunga poto, tawhiti rānei. Hei tāpiri, kei reira ngā kaiwhakawhitiwhiti muka whatu BiDi e āhei ai ngā kōwae ki te tuku me te whiwhi raraunga i runga i te muka kotahi hei whakahaere i ngā pūnaha taura, hei whakanui ake i te kaha whatunga, me te whakaiti i ngā utu. Hei tāpiri, ko ngā kōwae CWDM me DWDM e whakarea ana i ngā roangaru rerekē ki runga i te muka kotahi he pai mō te tuku tawhiti i roto i ngā whatunga WDM/OTN.
Te Rerekētanga i waenga i te Kaiwhakawhiti me te Transponder
He rite tonu te mahi a ngā pūrua me ngā kaiwhakawhitiwhiti e huri ana i ngā tohu hiko takirua-katoa ki ngā tohu whatu takirua-katoa. Ko te rerekētanga i waenganui i a rāua ko te whakamahi atanga raupapa a te kaiwhakawhitiwhiti muka whatu, ka taea te tuku me te whiwhi tohu i roto i te kōwae kotahi, ko te pūrua ia e whakamahi ana i te atanga whakarara, e hiahia ana kia rua ngā kōwae muka whatu hei whakatutuki i te tuku katoa. Arā, me tuku e te pūrua he tohu mā roto i te kōwae i tetahi taha, ā, ka whakautu te kōwae i tetahi taha ki taua tohu.
Ahakoa ka taea e te transponder te whakahaere ngāwari i ngā tohu whakarara tere iti iho, he nui ake tōna rahi me te kaha e pau ana i te transceiver. Hei tāpiri, ka taea anake e ngā kōwae whatu te whakarato i te huringa hiko-ki-whatu, engari ka taea e ngā transponder te whakatutuki i te huringa hiko-ki-whatu mai i tētahi roangaru ki tētahi atu. Nō reira, ka taea te whakaaro ko ngā transponder he transceiver e rua kua whakanohoia whakamuri, he nui ake te tūponotanga ka whakamahia mō te tuku tawhiti i roto i ngā pūnaha WDM kāore e taea te tae atu e ngā transceiver whatu noa.
Hei whakamutunga, he rerekē te mahi me te tono a ngā transceiver me ngā transponder. Ka taea te whakamahi i ngā repeater muka hei huri i ngā momo tohu rerekē, tae atu ki te aratau maha ki te aratau kotahi, te muka rua ki te muka kotahi, me te roangaru kotahi ki tētahi roangaru kē atu. Ko ngā transceiver, ka taea anake te huri i ngā tohu hiko ki ngā tohu whatu, kua roa e whakamahia ana i roto i ngā tūmau, ngā pana whatunga hinonga, me ngā whatunga pokapū raraunga.
