Ina tuku mai i tawhiti, ka whakamahia te muka hei tuku. No te mea he tawhiti rawa te tawhiti tuku o te muka whatu, te tikanga korero, ko te tawhiti tuku o te muka whatu aratau kotahi he neke atu i te 10 kiromita, me te tawhiti tuku o te muka whatu aratau maha ka tae ki te 2 km. I roto i nga whatunga muka whatu, he maha nga wa e whakamahia ana e matou nga transceivers muka. Na, me pehea ki te hono i te transceiver muka-whatu? Kia whai whakaaro tatou.
1. Ko te mahi a nga kaiwhakawhitiwhiti muka-whatu
1. Ka taea e te kaiwhakawhitiwhiti muka te whakawhānui i te tawhiti whakawhiti Ethernet me te whakawhānui i te radius kapinga Ethernet.
2. Ka taea te huri i te whakawhiti muka i waenga i te atanga hiko 10M, 100M, 1000M ranei Ethernet me te atanga mata.
3, te whakamahi i te whatu whatu transceiver ki te hanga i te whatunga e taea te whakaora i te haumi whatunga.
4. Ka pai ake te hononga i waenga i te tūmau, te tukurua, te poupou, te kāpeka me te kāpeka.
5, he microprocessor me te atanga tātaritanga te muka transceiver, ka taea e ia te whakarato i nga korero mahi hononga hononga raraunga.
2. Ko wai te mea ka whakarewahia, ko wai ranei ka whiwhi i te kaiwhakawhiti muka-whatu?
A, no te whakamahi i te whatu whatu transceiver, he maha nga hoa ka pa ki tenei patai:
1. Me whakamahi takirua te kaitahuri muka whatu?
2, whatu whatu transceiver he kahore ira, ko tetahi ki te riro tetahi ko ki te tuku? Ka taea ranei te whakamahi i nga whakawhiti muka e rua hei takirua?
3. Mēnā me whakamahi takirua te kaiwhakawhiti muka whatu, me rite te waitohu me te tauira o te takirua? Ka taea ranei e koe te whakamahi i tetahi huinga o tetahi waitohu?
He maha nga hoa kei te patai i tenei patai i te wa e whakamahia ana te kaupapa, he aha tena? Whakautu: Ka taea te whakamahi takirua muka whatu whatu hei taputapu hurihanga photoelectric, engari ka puta ano he whatu whatu whatu transceiver me te whatu whatu whakakā, whatu whatu transceiver me SFP transceiver pairing whakamahi hoki he noa, i roto i te parau tumu, rite te roa rite te roangaru tuku whatu he. te taua, he rite te hōputu tohu encapsulation me te tautoko i etahi kawa e taea te mohio korero muka whatu. Ko te aratau kotahi te muka takirua (ko te korero noa e hiahia ana kia rua nga muka) ko te kaiwhakawhitiwhiti ahakoa te kaiwhakawhiti me te mutunga whiwhi, mena ka taea te whakamahi i te takirua. Ko te kaikawe muka kotahi anake (me whai muka te whakawhitiwhitinga noa) ka wehe ke te mutunga tuku me te mutunga whiwhi.
Ahakoa he kaitahuri muka rua, he kaitahuri muka kotahi ranei me whakamahi takirua, ka taea e nga momo momo rereke te hototahi me te mahi tahi. Engari he rite tonu te tere, te roangaru, me te tauira. Ko te tikanga, ko nga reiti rereke (100 me te gigabit), nga roangaru rereke (1310nm me te 1300nm) kaore e taea te korero ki a raatau ano, i tua atu, ahakoa ko te waitohu kotahi o te whakawhiti muka kotahi me te muka takirua kaore i te hono tahi. Na ko te patai, he aha te kaitahuri muka kotahi, a he aha te kaitahuri muka rua? He aha te rereketanga i waenga i a raatau?
3. He aha te whakawhiti muka kotahi? He aha te whakawhiti muka-rua?
Ko te whakawhiti i te muka kotahi e pa ana ki te whakamahi i te taura whatu aratau kotahi, ko te whakawhiti i te muka kotahi he matua anake, ko nga pito e rua e hono ana ki te matua, ko nga pito e rua o te whakawhiti ma te whakamahi i nga roangaru marama rereke, na reira ka taea te tuku tohu marama i roto i te matua. Ko te whakawhiti i te muka takirua ko te whakamahi i nga matua e rua, he tuku he whiwhi, he makawe tetahi pito, me whakauru tetahi pito ki te tauranga, ko nga pito e rua hei whakawhiti.
1, whakawhiti muka kotahi
Me mohio te kaitahuri muka kotahi ki te mahi tuku me te mahi whiwhi. Ka whakamahia e ia te hangarau wehenga ngaru maha ki te tuku i nga tohu whatu e rua o nga roangaru rereke i roto i te muka whatu kia mohio ai te tuku me te tango.
No reira ka tukuna te kaitahuri-a-ira kotahi i roto i te muka, na reira ka tukuna te whakawhiti me te tango marama i roto i te muka muka i te wa ano. I roto i tenei take, me whakamahi kia rua nga roangaru o te marama ki te whakatutuki i nga korero noa.
No reira, e rua nga roangaru whatu o te waahanga whatu o te aratau kotahi-kotahi te roangaru, te tikanga 1310nm / 1550nm, no reira ka rereke nga pito e rua o te rua o nga kaiwhakawhitiwhiti. Ka tukuna e te kaiwhakawhitiwhiti kotahi te 1310nm ka whiwhi 1550nm. I tetahi atu pito, ka tukuna e ia te 1550nm ka whiwhi 1310nm. He watea mo nga kaiwhakamahi ki te wehewehe, ko te tikanga ka whakamahi reta hei utu. Whakamutunga A (1310nm / 1550nm) me te mutunga B (1550nm / 1310nm) ka puta. Ko nga kaiwhakamahi me AB takirua hei whakamahi, kaua ko te hononga AA, BB ranei. Ko te AB anake e whakamahia ana e te whakawhiti muka kotahi.
2, whakawhiti muka rua
Ko te whakawhiti muka rua he tauranga TX (taunga tuku) me te tauranga RX (tauranga whiwhi). He rite tonu te roangaru o nga tauranga e rua o te 1310nm, a ko te tangohanga he 1310nm, no reira ka whakamahia nga muka whatu whakarara e rua mo te hononga whakawhiti.
3, me pehea te wehewehe i te kaitahuri muka kotahi me te whakawhiti muka rua
E rua nga huarahi ki te wehewehe i nga kaikawe muka kotahi mai i nga kaikawe muka takirua.
① I te wa e whakaurua ana te kaikawe whatu whatu ki roto i te waahanga whatu, ka wehewehea te kaikawe muka whatu ki roto i te kaikawe muka kotahi me te kaikawe muka rua kia rite ki te maha o nga upoko pekepeke muka whatu hono. Ko te kaitahuri muka kotahi (matau) e hono ana ki te matua muka, ko ia te kawenga mo te tuku raraunga me te whiwhi raraunga, i te wa e hono ana te kaitahuri muka rua (taha maui) ki nga waahanga muka e rua, ko tetahi te kawenga mo te tuku raraunga me te ko etahi atu te kawenga mo te tango raraunga.
② Karekau he kōwae whatu tāmau i te kaitahuri muka whatu, he mea tika ki te wehewehe mena ko te kaitawhiti muka kotahi, ko te kaitahuri muka rua ranei e ai ki te waahanga whatu kua whakauruhia. I te wa e whakauruhia ana te whakawhiti muka whatu ki te muka kotahi te muka matarua, ara, he momo kotahi te atanga, ko tenei whakawhiti muka (tika); i te wa e whakaurua ana te kaitahuri muka me te muka rua o nga waahanga matarua, he momo taarua ranei te atanga, ko te kaiwhakawhiti he whakawhiti muka rua (ahua maui).
