Marka masaafada gudbintu aad u dheer tahay (in ka badan 100 km), calaamada indhaha waxay yeelan doontaa khasaare weyn.Waagii hore, dadku badanaa waxay isticmaali jireen soo-celinta indhaha si ay u xoojiyaan ishaarka indhaha.Qalabka noocan ah wuxuu leeyahay xaddidaadyo gaar ah oo ku saabsan codsiyada la taaban karo.Waxaa lagu bedelay cod-weyneeye fiber optic ah.Mabda'a shaqada ee cod-weyneeye fiber indhaha ayaa lagu muujiyay sawirka hoose.Waxay si toos ah u kordhin kartaa calaamadda indhaha iyada oo aan la marin habka beddelka indhaha-korontada-optical.
Sidee buu u shaqeeyaa cod-weyneeye fiber-ka?

Waa maxay noocyada amplifiers fiber ka jira?
1. Eerbium-doped fiber amplifier (EDFA)
Eerbium-doped fiber amplifier (EDFA) wuxuu inta badan ka kooban yahay erbium-doped fiber, isha iftiinka bamka, lammaanaha indhaha, go'doominta indhaha, iyo filter indhaha.Waxaa ka mid ah, erbium-doped fiber waa qayb muhiim ah oo ka mid ah kor u qaadista calaamadaha indhaha, taas oo inta badan loo isticmaalo si loo gaaro 1550 nm Band amplifier signalka indhaha, sidaas darteed, erbium-doped fiber amplifier (EDFA) wuxuu si fiican ugu shaqeeyaa xajmiga dhererka ee 1530 nm ilaa 1565 nm.
Afaa'iido:
Isticmaalka tamarta bamka ugu sarreeya (in ka badan 50%)
Waxay si toos ah iyo isku mar u kordhin kartaa ishaarka indhaha ee 1550 nm band
Hel wax ka badan 50 dB
Sawaxanka hooseeya ee gudbinta masaafada dheer
nusqaan
Erbium-doped fiber amplifier (EDFA) ayaa ka weyn
Qalabkani kama shaqayn karo isuduwidda qalabka kale ee semiconductor
2. Raman amplifier
Cod-weyneeye Raman waa aaladda kaliya ee ku kordhin karta calaamadaha indhaha ee 1292 nm ~ 1660 nm.Mabda'a shaqadu waxay ku salaysan tahay saamaynta firdhisan ee Raman ee la kiciyey ee fiber quartz.Sida ku cad shaxanka hoose, marka nalka bamka la jiido Marka signalka daciifka ah ee Mann ka heli bandwidth iyo mawjada iftiinka bamka xoog isku mar la kala qaado in fiber indhaha, signal iftiin daciif ah waa la kordhin doonaa sababtoo ah saamaynta kala firdhiso Raman. .
Afaa'iido:
Qeybo ballaaran oo lagu dabaqi karo
Waxaa loo isticmaali karaa codsiyada fiilooyinka fiber-ka ee hal-habka ah ee rakiban
Waxay kaabi kartaa cilladaha erbium-doped fiber amplifier (EDFA)
Isticmaalka korontadu yar yahay, hadalka isdhaafka oo hooseeya
cilladaysan:
Awoodda bamka sare
Nidaamka xakamaynta faa'iidada adag
buuq badan
3. Semiconductor Optical Fiber Amplifier (SOA)
Semiconductor Optical Fiber Amplifiers (SOA) waxay u adeegsadaan agabka semiconductor sida warbaahinta kasbashada, iyo gelinta calaamadaha indhaha iyo wax soo saarkooda waxay leeyihiin dahaar ka-hortagga milicsiga si looga hortago milicsiga wejiga dhamaadka cod-weyneeye oo baabi'iyo saameynta resonator-ka.
Afaa'iido:
mug yar
Awood wax soo saar hoose
Baaxadda faa'iidada waa yar tahay, laakiin waxaa loo isticmaali karaa kooxo badan oo kala duwan
Way ka jaban tahay erbium-doped fiber amplifier (EDFA) waxaana lagu isticmaali karaa qalabka semiconductor
Afar hawlgal oo aan toos ahayn oo ah habaynta faa'iidada isdhaafka ah, habaynta wejiga-tallaabo, beddelka hirarka dhererka iyo isku-dhafka afarta-mawjadaha waa la xaqiijin karaa
cilladaysan:
Waxqabadku maaha mid u sarreeya sida erbium-doped fiber amplifier (EDFA)
Qaylo badan iyo faa'iido hoose
