Te mātāpono me te whakamahinga oWhakakaha muka EDFA kua tāpirihia ki te erbium
Ko te hanganga taketake oEDFAHe whakakaha muka kua tāpirihia ki te erbium, he mea hanga nui tēnei mai i tētahi reo hohe (he maha ngā mita te roa o te muka quartz kua tāpirihia, he 3-5 maikorona te whānui o te matua, he kukū tāpiri (25-1000)x10-6), he pūtake mārama papu (990, 1480nm LD rānei), he hononga whatu me te wehewehe whatu. Ka taea e te mārama tohu me te mārama papu te horapa i te ahunga kotahi (te pupuhi tahi), te ahunga kē (te pupuhi whakamuri), ngā ahunga e rua rānei (te pupuhi rua-aronga) i roto i te muka Erbium. Ina werohia te mārama tohu me te mārama papu ki roto i te muka erbium i te wā kotahi, ka whakaohokia te katote erbium ki te taumata pūngao teitei (pūnaha taumata-toru) i raro i te mahi a te mārama papu, ā, ka pirau wawe ki te taumata pumau. Ina hoki ki te āhua whenua i raro i te mahi a te mārama tohu taupatupatu, ka tukuna te photon e rite ana ki te mārama tohu, kia whakanuia ai te tohu. He whānui te whānuitanga o te whānuitanga o te tukunga ohorere (ASE) kua whakanuia (tae atu ki te 20-40nm) ā, e rua ngā tihi e rite ana ki te 1530nm me te 1550nm.
Ngā painga matua oWhakakaha EDFAko te whakanui nui, te whānui whānui, te mana putanga nui, te pai o te papu, te ngaronga whakaurunga iti, me te kore e aro ki ngā āhua pōraruraru.
Ko te kaupapa mahi o te whakakaha muka erbium-doped
Ko te whakakaha muka kua tāpirihia ki te erbium（Whakakaha Whatu EDFA）Ko te nuinga o te mea he muka kua tāpirihia ki te erbium (tata ki te 10-30m te roa) me te pūtake mārama papu. Ko te kaupapa mahi ko te muka kua tāpirihia ki te erbium ka whakaputa i te hihi whakaoho i raro i te mahi a te pūtake mārama papu (roa ngaru 980nm, 1480nm rānei), ā, ka huri te mārama i tukuna me te huringa o te tohu mārama whakauru, he rite ki te whakanui i te tohu mārama whakauru. E whakaatu ana ngā hua ko te whakanui o te whakakaha muka kua tāpirihia ki te erbium he 15-40db te nuinga, ā, ka taea te whakanui ake i te tawhiti whakawhiti neke atu i te 100km. Nō reira, kāore e taea e te tangata te kore e pātai: he aha i whakaaro ai ngā kaipūtaiao ki te whakamahi i te erbium kua tāpirihia ki te whakakaha muka hei whakanui ake i te kaha o ngā ngaru mārama? E mōhio ana tātou he huānga whenua onge te erbium, ā, he āhuatanga hanganga motuhake ngā huānga whenua onge. Kua roa te whakamahinga o te tāpiri i ngā huānga whenua onge ki ngā taputapu whatu hei whakapai ake i te mahi a ngā taputapu whatu, nō reira ehara tēnei i te mea tūpono noa. Hei tāpiritanga, he aha i whiriwhiria ai te roangaru o te pūtake mārama papu i te 980nm, i te 1480nm rānei? Inaa, ko te roangaru o te pūtake mārama papu ka taea te 520nm, 650nm, 980nm, me te 1480nm, engari kua whakamātauhia e te mahi ko te roangaru o te whai huatanga taiaho o te pūtake mārama papu 1480nm te mea teitei rawa atu, ā, whai muri ko te roangaru o te pūtake mārama papu 980nm.
Hanganga ā-tinana
Hanganga taketake o te whakakaha muka erbium-whakaranu (Whakakaha Whatu EDFA). He wehewehe kei te pito whakauru me te pito whakaputa, ko te kaupapa he tuku i te tohu whatu ki te taha kotahi. Ko te roangaru o te papu whakaoho he 980nm, 1480nm rānei, ā, e whakamahia ana hei whakarato pūngao. Ko te mahi a te hononga he hono i te tohu whatu whakauru me te mārama papu ki roto i te muka erbium-whakaranu, me te whakawhiti i te pūngao o te mārama papu ki te tohu whatu whakauru mā te mahi a te muka erbium-whakaranu, kia tutuki ai te whakakaha pūngao o te tohu whatu whakauru. Hei whiwhi i te mana whatu putanga teitei ake me te taupū haruru iti iho, ko te whakakaha muka erbium-whakaranu e whakamahia ana i roto i te mahi ka tango i te hanganga o ngā pūtake papu e rua, neke atu rānei me ngā wehewehe i waenganui hei wehe i a rātou anō. Hei whiwhi i te pihi whakanui whānui ake, papatahi hoki, ka tāpirihia he tātari whakapapatahi whakanui.
E rima ngā wāhanga matua o te EDFA: te muka i pania ki te erbium (EDF), te hononga whatu (WDM), te wehewehe whatu (ISO), te tātari whatu, me te putunga papu. Ko ngā pūtake papu e whakamahia whānuitia ana ko te 980nm me te 1480nm, ā, he nui ake te pai o te papu o ēnei pūtake papu e rua, ā, he nui ake te whakamahinga. He iti ake te tauwehenga haruru o te pūtake mārama papu 980nm; he nui ake te pai o te papu o te pūtake mārama papu 1480nm, ā, ka nui ake te mana putanga (tata ki te 3dB teitei ake i te pūtake mārama papu 980nm).
painga
1. Ko te roangaru mahi e rite ana ki te matapihi whakaiti iti rawa o te muka aratau kotahi.
2. He pai te hononga. Nā te mea he whakakaha muka, he māmā te hono atu ki te muka tuku.
3. Teitei o te whai huatanga o te hurihanga pūngao. He iti ake te uho o te EDF i te uho o te muka tuku, ā, ka tukuna ngātahitia te rama tohu me te rama papu i roto i te EDF, nō reira he tino kukū te kaha whatu. Mā tēnei ka tino kī te taunekeneke i waenga i te rama me te reo whakanui Er ion, me te roa tika o te muka kua tāpirihia ki te erbium, nō reira he teitei te whai huatanga o te hurihanga o te pūngao rama.
4. Te pikinga teitei, te taupū haruru iti, te mana putanga nui, te whakawhitiwhiti iti i waenga i ngā hongere.
5. Ngā āhuatanga o te pikinga pumau: Kāore te EDFA e pāngia e te pāmahana, ā, he iti noa te hononga o te pikinga ki te pōraihana.
6. Kāore te āhuatanga whakanui e pā ana ki te tere moka o te pūnaha me te hōputu raraunga.
ngoikoretanga
1. Pānga kore-raina: Ka whakanuia e te EDFA te mana whatu mā te whakanui ake i te mana whatu i werohia ki roto i te muka, engari ko te nui ake ko te pai ake. Ina whakanuia te mana whatu ki tētahi taumata, ka puta te pānga kore-raina o te muka whatu. Nō reira, i te wā e whakamahi ana i ngā whakakaha muka whatu, me aro ki te uara o te whakahaere i te mana muka whatu kotahi-hongere e haere mai ana.
2. He pumau te whānuitanga o ngā roangaru whakanui: ko te whānuitanga mahi o te C-band EDFA he 1530nm~1561nm; ko te whānuitanga mahi o te L-band EDFA he 1565nm~1625nm.
3. Te whānui o te whānui o te whiwhinga kore taurite: He whānui rawa te whānui o te whiwhinga o te whakakaha muka EDFA i pania ki te erbium, engari kāore te whānuitanga whiwhinga o te EDF i te papatahi. Me whakamahi te tātari whakawhāiti whiwhinga hei whakawhāiti i te whiwhinga i roto i te pūnaha WDM.
4. Raruraru o te ngaru mārama: Ina he noa te ara mārama, ka haria atu ngā katote erbium e whakaohokia ana e te mārama papu e te mārama tohu, ā, ka oti te whakanui i te mārama tohu. Mena ka poroa te mārama whakauru, nā te mea ka haere tonu te kohikohi o ngā katote erbium pumau, ina whakahokia mai te mārama tohu whakauru, ka peke te pūngao, ka hua ake he ngaru mārama.
5. Ko te otinga mō te ngaru whatu ko te whakatinana i te mahi whakaiti mana whatu aunoa (APR) te mahi whakaweto mana whatu aunoa rānei (APSD) i roto i te EDFA, arā, ka whakaiti aunoa te EDFA i te mana, ka whakaweto aunoa rānei i te mana ina kore he rama whakauru, ā, ka pehi i te putanga mai o te āhuatanga ngaru.
Aratau tono
1. Ka whakamahia te Whakakaha Whakarei hei whakanui i te kaha o ngā tohu roangaru maha i muri i te ngaru whakarei, kātahi ka tuku atu. Nā te mea he nui te kaha tohu i muri i te ngaru whakarei, kāore i te tino teitei te taupū haruru me te whakanui o te whakakaha mana. He nui te mana putanga.
2. Ko te whakakaha-raina, i muri i te Whakakaha-mana, ka whakamahia hei utu i te ngaronga o te tuku raina i ia wā, e hiahiatia ana he taupū haruru iti me te mana whatu putanga nui.
3. Whakakaha-Mua: I mua i te wehewehe me muri i te whakakaha raina, ka whakamahia hei whakakaha i te tohu me te whakapai ake i te aro o te kaiwhiwhi (mēnā ka tutuki te ōwehenga tohu-ki-haruru whatu (OSNR) i ngā whakaritenga, ka taea e te mana whakauru nui ake te pehi i te haruru o te kaiwhiwhi me te whakapai ake i te aro o te kaiwhiwhi), ā, he tino iti te taupū haruru. Kāore he whakaritenga nui mō te mana putanga.
