Ngā āhuatanga oWhakakaha Whatu EDFA
Te roangaru mahi o te EDFAWhakakaha WhatuKei roto tonu i te awhe roangaru tino pai o te 1330-1600nm mō te whakawhitiwhiti muka whatu. Kua whānuitia te whakamahi i te Whakakaha Whatu EDFA e mahi ana i te roopu-C (1530-1565nm) me te matapihi ngaronga muka iti rawa. Hei whakamahi katoa i ngā rauemi whānui o ngā muka whatu, e whakapau kaha ana te iwi ki te whakawhanake i te Whakakaha Whatu EDFA i te roopu-L (1570-1610nm). Kei te hiku o te whānuitanga whakanui whakakaha EDFA te roopu-L, nō reira me whakamahi e te Whakakaha Whatu EDFA roopu-L ngā muka roa ake me te kaha papu teitei ake, me whakamahi rānei i ngā muka tino whakakīia.
He nui te whakanui o te Whakakaha Whatu EDFA (neke atu i te 30-50dB) ā, ka whakaratohia he whakanui papatahi ki runga i te whānuitanga auau (tae atu ki te 30nm), he pai mō te whakanui i ngā tohu i roto i ngā hongere whatu maha, inā koa i roto i ngā pūnaha wehewehenga roangaru matotoru (DWDM). He iti te haruru (4-8dB), e tata ana ki te rohe matū. Ina whakamahia ki ngā pūnaha WDM, ka whakaitihia te whakawhitiwhiti kōrero i waenga i ngā hongere, ā, ka taea te whakarōpū i ngā whakakaha maha. He nui te mana putanga saturation (10-20 dBm), ka taea te whakamahi hei whakakaha mana i muri i te tuku hei whakanui ake i te tawhiti tuku, i te maha rānei o ngā pona whatu kua tohaina me te kore he raina tuku. He iti te mana papu e hiahiatia ana (tekau milliwatts). Kāore te whakanui i te āhua polarization o te muka, nō reira he pai te pumau. He ngāwari ki te hono atu ki ngā muka whatu tuku, he iti te mate hononga (<1dB). Haunga te pūtake papu,Whakakaha EDFAhe mea tito mai i ngā wāhanga kore mahi. Nō reira, ki te whakaritea ki ngā whakawhiti hiko whakaora uaua, utu nui hoki, ka tino heke te utu o te pūnaha, ā, ka pai ake te pono. Hei tāpiri, ko ngā āhuatanga whakanui o te Whakakaha EDFA kāore e pā ki te tere moka pūnaha me te whakatakotoranga raraunga, nō reira ka taea e ia te whakanui me te tuku i ngā mōhiohio matihiko me ngā mōhiohio anaro.
Ko ngā ngoikoretanga o te Whakakaha Whatu EDFA: he rahi nui; he iti te roa o te ora o te pūtake papu; kāore e taea te whakauru atu ki ētahi atu taputapu, ā, ka whakawhāiti i te whakamahinga o te Whakakaha EDFA i roto i te whakaurunga hikohiko (OEIC). Hei tāpiri, ko te whānuitanga whiwhinga o te Whakakaha Whatu EDFA e kapi ana i tētahi wāhanga noa o te matapihi ngaronga iti o te muka aratau-kotahi quartz, e whakawhāiti ana i te maha o ngā hongere roangaru ka taea e te muka te whakauru, koinei anō hoki tōna ngoikoretanga.
