Pe a umi tele le mamao o le felauaiga (sili atu i le 100 km), o le faʻailoga mata o le ai ai se gau tele.I aso ua tuanaʻi, e masani ona faʻaogaina e tagata le faʻaogaina o mea faʻapipiʻi e faʻalautele ai le faailoilo.O lenei ituaiga meafaigaluega e iai ni tapula'a fa'apitoa i fa'atinoga fa'atino.Sui i le fa'alava opitika fa'aulu.O lo'o fa'aalia i le ata o lo'o i lalo le ta'iala galue a le fiber amplifier.E mafai ona faʻalauteleina saʻo le faʻailoga mata e aunoa ma le alu i le faʻagasologa o le liua o le optical-electrical-optical.
E fa'afefea ona fa'aogaina le fa'alava afi?
Pe a umi tele le mamao o le felauaiga (sili atu i le 100 km), o le faʻailoga mata o le ai ai se gau tele.I aso ua tuanaʻi, e masani ona faʻaogaina e tagata le faʻaogaina o mea faʻapipiʻi e faʻalautele ai le faailoilo.O lenei ituaiga meafaigaluega e iai ni tapula'a fa'apitoa i fa'atinoga fa'atino.Sui i le fa'alava opitika fa'aulu.O lo'o fa'aalia i le ata o lo'o i lalo le ta'iala galue a le fiber amplifier.E mafai ona faʻalauteleina saʻo le faʻailoga mata e aunoa ma le alu i le faʻagasologa o le liua o le optical-electrical-optical.
O a ituaiga mea fa'alava amplifi o lo'o iai?
1. Erbium-doped fiber amplifier (EDFA)
Erbium-doped fiber amplifier (EDFA) e masani lava ona aofia ai alava erbium-doped, puna moli pamu, mea faʻapipiʻi faʻapipiʻi, vaʻavaʻa faʻapitoa, ma faamama faʻapitoa.Faatasi ai ma i latou, o le fiber erbium-doped o se vaega taua o le faʻalauteleina o faʻailoga opitika, lea e masani ona faʻaaogaina e ausia ai le 1550 nm Band faʻamalosi faʻamalosi faʻailoga, o le mea lea, o le erbium-doped fiber amplifier (EDFA) e sili ona lelei i le galu umi o le 1530 nm i 1565 nm.
Alelei:
Ole fa'aogaina ole malosi ole pamu (sili atu ile 50%)
E mafai ona faʻapipiʻi tuusaʻo ma faʻateleina le faʻailoga mata i le 1550 nm band
Maua sili atu i le 50 dB
Le pisapisao maualalo i felauaiga mamao
faaletonu
O le fa'aulu fibre-doped erbium (EDFA) e tele
O nei meafaigaluega e le mafai ona galulue faʻatasi ma isi masini semiconductor
2. Fa'amalo Raman
O le Raman amplifier e naʻo le pau lea o le masini e mafai ona faʻalauteleina faailoilo i le 1292 nm ~ 1660 nm band.O lona taʻiala galue e faʻavae i luga o le faʻamalosia o Raman faʻasalalau aafiaga i le quartz fiber.E pei ona faʻaalia i le ata o loʻo i lalo, pe a tosoina le moli pamu Pe a maua le faʻailoga vaivai o le Mann i le bandwidth ma le malosi o le galu o le moli o loʻo tuʻuina atu i le taimi lava e tasi i le fiber opitika, o le a faʻateleina le faailo o le malamalama ona o le faʻamaʻi faʻamaʻi Raman. .
Alelei:
Tele ituaiga o fusi talafeagai
E mafai ona fa'aogaina i fa'apipi'i fa'apipi'i fa'alava fa'apipi'i fa'apipi'i
E mafai ona fa'aopoopoina le fa'aletonu ole fa'alava fa'alava erbium-doped (EDFA)
Fa'aitiitia le fa'aogaina o le eletise, maualalo le crosstalk
faaletonu:
Mana maualuga pamu
Faiga fa'aletonu o tupe maua
Pisa
3. Semiconductor alava fa'alava fa'aola (SOA)
Semiconductor optical fiber amplifier (SOA) faʻaogaina mea semiconductor e avea ma ala faʻasalalau, ma o latou faʻailoga mataʻutia o loʻo i ai ma mea e maua ai faʻapipiʻi e puipuia ai le mafaufau i le pito pito o le faʻamalosi ma faʻaumatia le aʻafiaga o le resonator.
Alelei:
itiiti leo
Malosi maualalo
E laʻititi le bandwidth gain, ae e mafai ona faʻaaogaina i le tele o vaega eseese
E sili atu le taugofie nai lo le erbium-doped fiber amplifier (EDFA) ma e mafai ona faʻaogaina i masini semiconductor.
E fa fa'agaioiga le fa'aogaina o le fa'aogaina o feso'ota'iga, fa'asologa fa'asolosolo, suiga o le galu ma le fa'afefiloi o galu e mafai ona iloa.
faaletonu:
E le maualuga le faatinoga e pei o le erbium-doped fiber amplifier (EDFA)
Le pisa maualuga ma maualalo le maua
