Ko te kōwae whatu he mea titoa he taputapu optoelectronic, iahiko mahi me nga atanga whatu.Kei roto i te taputapu optoelectronic te tuku me te tango i nga waahanga.Ko te nuinga o nga waahanga oro e whakamahia ana i roto i nga whakawhitiwhiti korero, nga pokapū raraunga me etahi atu waahi.Na, he aha te mea he kōwae whatu?He aha te whakamahinga o nga waahanga whatu?Whai muri, me whai i te ētita o Feichang Technology ki te ako atu mo tena!
Maamaa noa, ko te mahi a te kōwae whatu ko te hurihanga whakaahua.Ko te mutunga tuku ka huri i te tohu hiko ki te tohu whatu.I muri i te tukunga ma te muka whatu, ka huri te mutunga whiwhi i te tohu whatu hei tohu hiko.
I tua atu, ka whakarōpūtia nga kōwae optical i runga i te kohinga ka taea te wehewehe ki:
1. Ko te kōwae whatu XFP he transceiver whatu wera-swappable motuhake o te kawa kōrero.Ka whakamahia mo te 10G bps Ethernet, SONET/SDH, me te hongere muka whatu.
2. SFP kōwae whatu, small pluggable receiving modules and light emitting modules (SFP), kei te whakamahia whānuitia i tēnei wā.
3. Ko te raupapa GigacBiDi nga waahanga matarua kotahi-muka e whakamahi ana i te hangarau WDM kia mohio ai te tuku muka o nga korero e rua-ara (whakawhitinga tohu-ki-ira. Inaa, he iti rawa nga rauemi muka, a ka hiahiatia kia kotahi te muka ki te tuku tohu tohu-rua. ).Kei roto i te GigacBiDi te SFP kotahi te muka takirua (BiDi), te GBIC te muka kotahi te rua (BiDi), te SFP + te muka kotahi (BiDi), te XFP te muka kotahi (BiDi), te SFF te muka kotahi te matarua (BiDi) me etahi atu.
4. Kōwae tauranga hiko, RJ45 tauranga hiko kōwae pluggable iti, hoki e mohiotia ana ko kōwae hiko kōwae tauranga hiko ranei.
5. Ka wehewehea nga waahanga matakite SFF ki te 2x5, 2x10, me etahi atu e ai ki o ratou titi.
6. GBIC kōwae whatu, Gigabit Ethernet atanga converter (GBIC) kōwae.
7. PON kōwae whatu, hāngū whatu whatunga PON (A-PON, G-PON, GE-PON) kōwae whatu.
8. 40Gbs teitei-tere kōwae whatu.
9. Kōwae tuku SDH (OC3, OC12).
10. Kōwae rokiroki, pērā i 4G, 8G, etc.
Na, tirohia konei, he aha te SFP kōwae whatu?Kei te mohio koe ki te whakautu ki tenei patai?Na, he aha te mahi o te kōwae whatu SFP?
Ko te kōwae whatu SFP he kōwae pōkai iti ka taea te whakawhiti wera i roto i te mōkihi SFP.Ko te reeti gao o naianei ka tae ki te 10.3G, a ko te atanga ko LC.Ko te kōwae whatu SFP te nuinga tito o te taiaho.I tua atu, ko te SFP kōwae whatu ngā o: taiaho: tae atu fa transmitter TOSA me te kaiwhiwhi ROSA;IC poari iahiko;Ko nga taputapu o waho ko: te anga, te turanga, te PCBA, te mowhiti toia, te peera, te wahi wetewete, te mono rapa.I tua atu, ka taea te whakarōpūtia nga waahanga matakite SFP kia rite ki te tere, te roangaru, me te aratau.
Te whakarōpū reiti
E ai ki te tere, he 155M / 622M / 1.25G / 2.125G / 4.25G / 8G / 10G, 155M me 1.25G e whakamahia ana i te maakete.Kua pakeke haere te hangarau 10G, a kei te piki haere te hiahia.whanaketanga o.
Te whakarōpūtanga roangaru
E ai ki te roangaru, he 850nm / 1310nm / 1550nm / 1490nm / 1530nm / 1610nm.Ko te roangaru he 850nm mo te SFP multimode, ko te tawhiti tuku kei raro iho i te 2KM, ko te roangaru ko 1310 / 1550nm mo te aratau kotahi, a ko te tawhiti whakawhiti kei runga ake i te 2KM.Ko te utu o nga roangaru e toru he iti ake i era atu e toru.
He ngawari ki te whakapoauau i te waahanga karekau mena kaore he tohu.Ko te tikanga, ka wehewehe nga kaihanga i te tae o te mowhiti kume.Hei tauira, he maha-aratau te mowhiti kume pango me te roangaru he 850nm;ko te kahurangi te kōwae me te roangaru o te 1310nm;**ko te roangaru ko 1550nm Te kōwae;he kōwae te papura he 1490nm te roangaru, aha atu.
Te whakarōpū tauira
SFP kōwae whatu multimode
Tata ki te katoa o nga muka whatu multimode he 50/125um, 62.5/125um ranei te rahi, me te whanui (te nui o nga korero e tukuna ana e te muka whatu) ko te nuinga o te 200MHz ki te 2GHz.Ka taea e nga kaiwhakawhiti whatu aratau maha te whakawhiti ki te 5 kiromita ma roto i nga muka whatu aratau maha.Whakamahia nga diodes maramara, laser ranei hei puna marama.He pango te tae o te mowhiti kume, o waho ranei.
SFP kōwae whatu aratau kotahi
Ko te rahi o te muka aratau kotahi ko te 9-10/125?m, ka whakatauritea ki te muka aratau-maha, he whanui kore mutunga me nga ahuatanga mate iti.Ka whakamahia te nuinga o te kaitahuri whatu aratau kotahi mo te whakawhiti tawhiti, i etahi wa ki te 150 ki te 200 kiromita.Whakamahia te LD, te LED ranei me te raina matakite whaiti hei puna marama.
