Ina he roa rawa te tawhiti tuku (neke atu i te 100 kiromita), ka mate nui te tohu whatu.I nga wa o mua, ko te nuinga o nga wa ka whakamahia e te tangata nga tukurua whatu hei whakanui i te tohu whatu.Ko tenei momo taputapu he herenga i roto i nga mahi mahi.Ka whakakapihia e te whakakaha muka whatu.Ko te kaupapa mahi o te whakakaha muka whatu e whakaatuhia ana i te ahua i raro nei.Ka taea e ia te whakanui tika i te tohu whatu me te kore e haere i roto i te tukanga o te huringa whatu-hiko-whatu.
He pehea te mahi o te whakakaha muka?
Ina he roa rawa te tawhiti tuku (neke atu i te 100 kiromita), ka mate nui te tohu whatu.I nga wa o mua, ko te nuinga o nga wa ka whakamahia e te tangata nga tukurua whatu hei whakanui i te tohu whatu.Ko tenei momo taputapu he herenga i roto i nga mahi mahi.Ka whakakapihia e te whakakaha muka whatu.Ko te kaupapa mahi o te whakakaha muka whatu e whakaatuhia ana i te ahua i raro nei.Ka taea e ia te whakanui tika i te tohu whatu me te kore e haere i roto i te tukanga o te huringa whatu-hiko-whatu.
He aha nga momo whakakaha muka kei reira?
1. Whakakaha muka-doped Erbium (EDFA)
Erbium-doped fiber amplifier (EDFA) Ko te nuinga o te titoa o te muka erbium-doped, te puna marama papu, te hono whatu, te kaiwehe whatu, me te tātari whatu.I roto i a raatau, ko te muka erbium-doped he waahanga nui o te whakakaha tohu tohu, e whakamahia ana ki te whakatutuki i te 1550 nm Band whakakaha tohu whatu, no reira, he pai te mahi a te erbium-doped fiber amplifier (EDFA) i roto i te roangaru o te 1530 nm ki 1565 nm.
Apainga:
Ko te whakamahi mana papu teitei (neke atu i te 50%)
Ka taea e ia te whakakaha tika me te wa kotahi te whakanui i te tohu whatu i roto i te roopu 1550 nm
Neke atu i te 50 dB
Haruru iti i roto i te tuku tawhiti
ngoikoretanga
He nui ake te whakakaha muka erbium-doped (EDFA).
Kaore e taea e enei taputapu te mahi tahi me etahi atu taputapu semiconductor
2. Whakanuia Raman
Ko te whakakaha Raman anake te taputapu ka taea te whakakaha i nga tohu whatu i roto i te roopu 1292 nm~1660 nm.Ko tana maataapono mahi e ahu mai ana i te whakaihiihi i te whakamararatanga o Raman i roto i te muka kiripaka.Ka rite ki te whakaatu i roto i te ahua i raro nei, ka toia te rama papu I te wa e tukuna ana te tohu marama ngoikore i roto i te Mann te bandwidth me te ngaru marama papu kaha ka tukuna i te wa kotahi i roto i te muka whatu, ka whakanuia te tohu marama ngoikore na te whakamararatanga o Raman. .
Apainga:
Te whānuitanga o nga roopu e tika ana
Ka taea te whakamahi i roto i nga tono taura muka aratau kotahi
Ka taea te taapiri i nga ngoikoretanga o te whakakaha muka erbium-doped (EDFA)
He iti te kohi hiko, he iti te korero whakawhiti
ngoikoretanga:
Te mana papu teitei
Pūnaha mana whiwhi matatini
Haruru
3. Semiconductor muka whatu tīwerawera (SOA)
Ko te Semiconductor optical fiber amplifiers (SOA) e whakamahi ana i nga rauemi semiconductor hei kaikawe korero, a ko o raatau tohu whakaurunga me te whakaputanga he paninga anti-whakaata hei aukati i te whakaata i te mata mutunga o te whakanui me te whakakore i te paanga o te resonator.
Apainga:
rōrahi iti
He iti te mana whakaputa
He iti te bandwidth whiwhi, engari ka taea te whakamahi i nga roopu rereke maha
He iti ake i te erbium-doped fiber amplifier (EDFA) ka taea te whakamahi me nga taputapu semiconductor.
E wha nga mahi kore-raina o te whakarereketanga whakawhiti, te whakawhiti-waahanga, te hurihanga roangaru me te whakaranu ngaru e wha ka taea te whakatutuki
ngoikoretanga:
Ko te mahi kaore i te teitei ake i te whakakaha muka erbium-doped (EDFA)
Te haruru nui me te painga iti
