Whakaahuatanga: Whakakaha muka kua tāpirihia ki te erbiumWhakakaha Whatu EDFA
Whakakaha muka whatu kua tāpirihia ki te erbium (EDFA, arā, ko te whakakaha tohu whatu me te Er3 + i tāpirihia ki te matua muka mā te tohu) ko te whakakaha whatu tuatahi i whakawhanakehia e te Whare Wānanga o Southampton i te tau 1985, ā, ko tētahi o ngā mea hou nui rawa atu i roto i te whakawhitiwhiti muka whatu. Ko te muka i tāpirihia ki te erbium he momo muka he iti noa iho ngā iona o te huānga whenua onge erbium (Er) i roto i te muka quartz, koinei te matua oWhakakaha muka kua tāpirihia ki te erbiumMai i te mutunga o te tekau tau atu i 1980, kua puta he whanaketanga nui i roto i te rangahau i ngā whakakaha muka kua tāpirihia ki te erbium. Kua tino whakanuia e te hangarau WDM te kaha o te whakawhitiwhiti muka whatu. Koinei te whakakaha whatu e whakamahia whānuitia ana i roto i te whakawhitiwhiti muka whatu.
Te Whakamahinga: Ko te whakakaha muka whatu he taputapu whakakaha whatu e whakakaha tika ana i te tohu whatu i roto i te pūnaha whakawhitiwhiti muka whatu. I roto i te pūnaha whakawhitiwhiti e whakamahi ana i te muka whatu, he hangarau e whakakaha tika ana i te tohu whatu me te kore e huri i te tohu whatu hei tohu hiko. Ko te whakakaha muka kua tāpirihia ki te erbium (EDFA Optical Amplifier, arā, te whakakaha tohu whatu me te ion erbium Er3 + i roto i te matua muka mā te tohu) ko te whakakaha whatu tuatahi i whakawhanakehia e te Whare Wānanga o Southampton i te United Kingdom me te Whare Wānanga o Tohoku o Hapani, ko tētahi o ngā mea hou nui rawa atu i roto i te whakawhitiwhiti muka whatu. Ko te muka kua tāpirihia ki te erbium he momo muka he iti noa iho ngā ion erbium (Er) o te huānga whenua onge i roto i te muka quartz, koinei te matua o te whakakaha muka kua tāpirihia ki te erbium. Mai i te mutunga o te tekau tau atu i 1980, kua puta he whanaketanga nui i roto i te rangahau o ngā whakakaha muka kua tāpirihia ki te erbium. Kua tino whakanuia e te hangarau WDM te kaha o te whakawhitiwhiti muka whatu. Koinei te whakakaha whatu e whakamahia whānuitia ana i roto i te whakawhitiwhiti muka whatu.

Ingoa kupu: Whakakaha muka kua pania ki te erbium
Kupu e pā ana:Whakakaha Whatu
Ka taea e te muka kuata kua whakaranua ki ngā huānga whenua onge (pērā i te Nd, Er, Pr, Tm, me ētahi atu) te hanga i tētahi pūnaha taiaho maha-taumata, ā, ka whakanui tika i te mārama tohu whakauru i raro i te mahi a te mārama papu. Whai muri i te tuku urupare tika, ka hangaia te taiaho muka. Ko te roanga ngaru mahi o te whakakaha muka kua whakaranua ki te ND he 1060nm me te 1330nm, engari he iti noa te whanaketanga me te whakamahinga nā te peka ke mai i te tauranga pai o te whakawhitiwhiti muka me ētahi atu take. Ko ngā roanga ngaru mahi o te EDFA me te PDFA kei roto i te matapihi ngaronga iti rawa (1550nm) me te roanga ngaru marara kore (1300nm) o te whakawhitiwhiti muka whatu, ā, ka mahi te TDFA i roto i te roopu-S, he tino pai mō ngā tono pūnaha whakawhitiwhiti muka whatu. Ina koa ko te EDFA, te whanaketanga tere rawa atu, he whai hua.
I runga i te whanaketanga o te muka erbium-whakaurunga, he maha tonu ngā whakakaha muka hou e puta mai ana. Hei tauira, ko te whakakaha muka takirua-rohe (DBFA) e hangai ana ki te muka erbium-whakaurunga he whakakaha whatu whānui, ā, ka taea e te whānui te kapi i te nuinga o te roangaru wehewehenga maha-wāhanga (WDM). Ko tētahi hua rite ko te whakakaha whatu ultra-whānui (UWOA), e kaha ana ki te whakakaha i te 100 hongere roangaru i roto i te muka kotahi.
Te tono whai hua
Mā te whakamahinga o te whakakaha muka kua tāpirihia ki te erbium (EDFA Amplifier) i roto i te pūnaha whakawhitiwhiti matihiko muka whatu tuku iho ka taea te penapena i te maha o ngā Whakahoki Whatu, ā, ka tino whakanuia te tawhiti o te whakawhiti, he mea tino nui tēnei mō te pūnaha taura tawhiti.
Ko ōna tono matua ko:
1, ka taea te whakamahi hei whakakaha tawhiti mārama. He maha ngā herenga o ngā Whakahoki muka whatu hiko tuku iho. Hei tauira, ina hurihia te tohu matihiko me te tohu anaro ki a rātou anō, me whakarerekē te whakahoki kia rite; ina huri te taputapu mai i te tere iti ki te tere teitei, me whakakapi te whakahoki kia rite. Ka tukuna noa te roangaru kotahi o te tohu mārama, ā, he uaua te hanganga, he utu nui, me ētahi atu. Ka wikitoriahia ēnei ngoikoretanga e ngā whakakaha muka kua tāpirihia ki te erbium, ehara i te mea kāore e hiahiatia kia whakarerekētia me te whakarerekētanga o te aratau tohu, engari kāore hoki e hiahiatia kia whakakapia ina whakawhānuihia te taputapu, ina whakamahia rānei mō te wehewehe roangaru whatu.
2, ka taea te whakamahi hei pou whakakaha o te tuku whatu me te whakakaha o te kaiwhiwhi whatu. Hei pou whakakaha o te tuku whatu, ka taea te whakanui ake i te mana tuku o te taiaho mai i te 0db ki te +10db. Ina whakamahia hei whakakaha o te kaiwhiwhi whatu, ka taea hoki te whakapai ake i tōna aro. Nō reira, 1-2 noa iho ngā whakakaha kua tāpirihia ki te erbium ka whakatakotoria ki te raina, ā, ka taea te whakanui ake i te tawhiti tuku tohu mā te 100-200km.
Hei tāpiritanga, ko te whakakaha muka kua tāpirihia ki te erbium (Whakakaha EDFA) hei whakaoti rapanga. Kua mōhiotia e te ao ngā painga ahurei o ngā whakakaha muka kua tāpirihia ki te Erbium, ā, kua whānui haere te whakamahinga. Heoi, he iti anō hoki ngā herenga o ngā whakakaha muka kua tāpirihia ki te Erbium. Hei tauira, kāore e taea te piki me te heke i roto i te whakawhitiwhiti kōrero tawhiti, he uaua ake te whakapā atu ki te teihana, he uaua ki te kimi hapa, kāore e roa te ora o te pūtake mārama papu, me te haere tonu o te hangarau whakawhitiwhiti kōrero muka whatu, ka ea pai ēnei raruraru.
