Te Mārama ki ngā Āpitihanga SC/APC
Te Hoahoa me te Hanganga o ngā Āpiti SC/APC
Ngā urutau SC/APCHe tino āta hangaia kia tika ai te tūnga me te mau o ngā hononga i roto i ngā whatunga muka whatu. He kākāriki te āhua o ēnei urutau, e wehewehe ana i a rātou i ētahi atu momo pēnei i ngā urutau SC/UPC. Ko te kākāriki e tohu ana i te whakamahinga o te paninga whakapā ā-tinana koki (APC) ki te mata pito muka. Ko tēnei hoahoa koki, i te nuinga o te wā i te koki 8-tohu, ka whakaiti i ngā whakaata whakamuri mā te arahi i te mārama kia matara atu i te pūtake.
Ko te hanganga o ngā urutau SC/APC he mea whakamahi i ngā rauemi kounga teitei pērā i ngā ringaringa uku zirconia. He tino pakari ēnei ringaringa, ā, he tika hoki te tūnga o ngā matua muka. Kei roto hoki i ngā urutau he whare kirihou, he whare whakarewa pakari, e tiaki ana i ngā wāhanga o roto, e whakapai ake ana hoki i te roa o te ora. Mā te hangarau tika o ēnei urutau ka iti te ngaronga whakaurunga me te ngaronga hokinga nui, ā, he pai mō ngā whatunga muka whatu mahi teitei.
Te Mahi a ngā Āpiti SC/APC i ngā Whatunga Tere-Tiketike
He mea nui te mahi a ngā urutau SC/APC ki te pupuri i te whai huatanga o ngā whatunga tere-teitei. Ka honoa e rātou ngā taura muka whatu e rua, kia iti ai te ngaronga o ngā tohu mārama. Ka whakaitihia e te pito koki o te urutau SC/APC te whakaata o te tohu, he mea nui tēnei mō te pupuri i te pono o te tuku raraunga i ngā tawhiti roa.
I roto i ngā hanganga muka whatu o ēnei rā, ka whakawhirinaki nui ngā whatunga aratau-kotahi kiNgā urutau SC/APC. Kua hangaia ēnei whatunga mō te tuku tawhiti me te whānui o te hononga, e hanga ana i teiti te ngaronga whakaurunga me ngā āhuatanga ngaronga hokinga teiteihe mea nui ngā urutau SC/APC. Mā te whakaiti i te hekenga o te tohu, ka whakarite ēnei urutau i ngā tere whakawhiti raraunga tino pai, he mea nui ēnei mō ngā tono pēnei i ngā pokapū raraunga, te rorohiko kapua, me ngā ratonga mariko.
Ko te pono o ngā urutau SC/APC i ahu mai i te whakamahinga o ngā rauemi kounga teitei me te hangarau tino tika. He mea nui tēnei pono mō te pupuri i ngā hononga mahi-teitei i roto i ngā taiao ka taea e ngā ngaronga tohu iti te arahi ki ngā whakararuraru nui. Nō reira, kua noho ngā urutau SC/APC hei wāhanga tino nui i roto i te whanaketanga o ngā whatunga muka whatu tere-teitei hou.
Ngā Painga o ngā Āpiti SC/APC i roto i ngā Whatunga muka whatu
Te Whakataurite ki ngā Hononga UPC me te PC
He rerekē ngā painga o ngā hononga SC/APC i ngā hononga UPC (Ultra Physical Contact) me PC (Physical Contact), ā, koinei te mea tino pai rawa atukōwhiringa pai mō te mahi teiteiwhatunga muka whatu. Ko te rerekētanga matua kei roto i te āhua o te mata pito hononga. Ahakoa he mata papatahi, he oro te āhua o ngā hononga UPC, ka whakamahia e ngā urutau SC/APC he mata pito koki 8-tohu. Ka whakaitihia e tēnei hoahoa koki te whakaata whakamuri mā te tuku i te mārama whakaata ki roto i te whakakikorua, kaua ki te whakamuri ki te pūtake.
E whakaatu ana ngā inenga mahi i te hiranga o ngā urutau SC/APC. Ko te tikanga ka tutuki i ngā hononga UPC te ngaronga hokinga mai o te -55 dB, engari ko ngā urutau SC/APC ka tukuna hete ngaronga whakahoki e neke atu ana i te -65 dB. Mā tēnei ngaronga whakahokinga teitei ake ka pai ake te pono o te tohu, ka pai ai ngā urutau SC/APC mō ngā tono pēnei i te FTTx (Fiber to the x) me ngā pūnaha WDM (Wavelength Division Multiplexing). He rerekē, he pai ake ngā hononga UPC mō ngā whatunga Ethernet, he iti ake te hiranga o te ngaronga whakahokinga. Ko ngā hononga PC, me te ngaronga whakahokinga tata ki te -40 dB, ka whakamahia whānuitia i roto i ngā taiao iti ake te uaua.
Ko te kōwhiringa i waenga i ēnei hononga ka whakawhirinaki ki ngā whakaritenga motuhake o te whatunga. Mō te whānui-rahi, te tawhiti-roa, teTuku tohu ataata RFI roto i ngā tono, ka whakaratohia e ngā urutau SC/APC te mahi tino pai. Nā tō rātou kaha ki te whakaiti i te whakaata me te pupuri i te kounga tohu, he mea nui ēnei i roto i ngā hanganga muka whatu hou.
Ngaronga Whatu Iti me te Ngaronga Whakahoki Nui
He tino pai ngā urutau SC/APC ki te whakariteiti te ngaronga whatume te nui o te ngaronga whakahoki, e rua ngā mea nui mō te tuku raraunga whai hua.iti te ngaronga whakaurungaMā te whakamahi i ēnei urutau ka taea te whakarite kia tae atu tētahi wāhanga nui o te tohu taketake ki tōna ūnga, ka whakaitihia te ngaronga hiko i te wā e tukuna ana. He mea nui tēnei āhuatanga mō ngā hononga tawhiti, ina taea e te whakaitiititanga o te tohu te whakararu i te mahi a te whatunga.
Ko te kaha nui o te ngaronga whakahoki o ngā urutau SC/APC ka whakarei ake i tō rātou ataahua. Mā te mimiti i te mārama whakaata ki roto i te uhi, ka whakaitihia te whakaata whakamuri e te mata pito koki 8-tohu. Ehara i te mea ka whakapai ake tēnei āhuatanga hoahoa i te kounga tohu anake engari ka whakaitihia hoki te pokanoa, he mea nui hei pupuri i te pono o te tuku raraunga tere-teitei. Kua whakaatuhia e ngā whakamātautau taiwhanga te mahi pai rawa atu o ngā urutau SC/APC, mengā uara ngaronga whakaurunga i te nuinga o te wā tata ki te 1.25 dBme te ngaronga hokinga mai e neke atu ana i te -50 dB.
Mā ēnei inenga mahi ka kitea te pono o ngā urutau SC/APC i roto i ngā taiao uaua. Nā te kaha ki te pupuri i te iti o te ngaronga whatu me te nui o te ngaronga whakahokinga mai, ka waiho hei tūāpapa mō ngā whatunga tere-nui, ka whakarite kia pai te whakawhiti raraunga me te whakaiti i te wā kore mahi.
Ngā Taupānga i roto i ngā Taiao Whatunga Kiato-Teitei me ngā Taiao Whatunga Tino Hira
Ko ngā urutau SC/APChe mea nui i roto i te kiato teiteime ngā taiao whatunga nui, he mea nui te mahi me te pono. Ko ngā pokapū raraunga, ngā hanganga rorohiko kapua, me ngā ratonga mariko e whakawhirinaki nui ana ki ēnei urutau hei pupuri i te mahi whatunga tino pai.
