Marka masaafada gudbinta ay aad u dheer tahay (in ka badan 100 km), calaamadda indhaha ayaa khasaare weyn yeelan doonta. Waagii hore, dadku waxay badanaa isticmaali jireen ku celceliyeyaasha indhaha si ay u xoojiyaan calaamadda indhaha. Qalabka noocan ah wuxuu leeyahay xaddidaadyo gaar ah oo ku saabsan codsiyada wax ku oolka ah. Waxaa lagu beddelay amplifier-ka fiber-ka indhaha. Mabda'a shaqada ee amplifier-ka fiber-ka indhaha ayaa lagu muujiyay sawirka hoose. Waxay si toos ah u xoojin kartaa calaamadda indhaha iyada oo aan la marin habka beddelka indhaha-korontada-optica.
Sidee buu u shaqeeyaa qalabka wax lagu dhejiyo ee fiber-ka?

Noocyada amplifiers-ka fiber-ka maxay yihiin?
1. Qalab-sameeyaha Fiber-ka ee Erbium-ku-darka ah (EDFA)
Amplifier-ka fiilada Erbium-doped (EDFA) wuxuu inta badan ka kooban yahay faybar erbium-doped ah, isha iftiinka bamka, isku xidhka indhaha, go'doominta indhaha, iyo shaandhada indhaha. Kuwaas waxaa ka mid ah, faybarka erbium-doped waa qayb muhiim ah oo ka mid ah kor u qaadista calaamadaha indhaha, kaas oo inta badan loo isticmaalo in lagu gaaro kor u qaadista calaamadaha indhaha ee Band 1550 nm, sidaas darteed, kor u qaadista fiilada erbium-doped (EDFA) waxay si fiican ugu shaqeysaa inta u dhaxaysa mowjadaha 1530 nm ilaa 1565 nm.
Afaa'iido:
Isticmaalka awoodda bamka ugu badan (in ka badan 50%)
Waxay si toos ah iyo isku mar u kordhin kartaa calaamadda indhaha ee ku jirta xadka 1550 nm
Kasbashada wax ka badan 50 dB
Buuqa hoose ee gudbinta masaafada dheer
cillad
Amplifier-ka fiilada Erbium-doped (EDFA) wuu ka weyn yahay
Qalabkani ma shaqayn karo iyadoo lala kaashanayo qalabka kale ee semiconductor-ka
2. Raman amplifier
Amplifier-ka Raman waa qalabka kaliya ee xoojin kara calaamadaha indhaha ee ku jira xarigga 1292 nm ~ 1660 nm. Mabda'a shaqadeedu waxay ku salaysan tahay saamaynta kala firdhinta Raman ee kicisa ee ku jirta fiber-ka quartz. Sida ka muuqata sawirka hoose, marka la jiido nalka bamka Marka calaamadda iftiinka daciifka ah ee ku jirta Mann ay korodho baaxadda iyo hirarka iftiinka bamka ee xooggan isku mar lagu gudbiyo fiilada indhaha, calaamadda iftiinka daciifka ah ayaa la kordhin doonaa sababtoo ah saameynta kala firdhinta Raman.
Afaa'iido:
Noocyo badan oo ah kooxo khuseeya
Waxaa loo isticmaali karaa codsiyada fiilooyinka fiber-ka hal-qaab ee la rakibay
Waxay kaa caawin kartaa cilladaha qalabka wax lagu dhejiyo ee erbium-doped fiber amplifier (EDFA)
Isticmaalka awoodda oo hooseeya, isdhaafsiga hoose
cillad:
Awoodda bamka sare
Nidaamka xakamaynta faa'iidada ee adag
Qaylo badan
3. Qalab-sameeyaha fiber-ka indhaha ee semiconductor (SOA)
Amplifiers-ka fiber optical fiber (SOA) waxay u isticmaalaan agabka semiconductor-ka sidii warbaahinta gain, gelinta iyo soo saarista calaamadahooda indhaha waxay leeyihiin dahaadh ka hortagga milicsiga si looga hortago milicsiga wejiga ugu dambeeya ee amplifier-ka loona baabi'iyo saameynta resonator-ka.
Afaa'iido:
mug yar
Awood yar oo wax soo saar ah
Baaxadda faa'iidada waa yar tahay, laakiin waxaa loo isticmaali karaa kooxo badan oo kala duwan
Waa ka raqiisan yahay amplifier-ka fiber-ka ee erbium-doped (EDFA) waxaana loo isticmaali karaa qalabka semiconductor-ka.
Afar hawlgal oo aan toos ahayn oo ah habaynta faa'iidada iskutallaabta, habaynta wejiga isdhaafsiga, beddelka hirarka iyo isku darka afar-hir ayaa la xaqiijin karaa
cillad:
Waxqabadku ma aha mid aad u sarreeya sida qalabka wax lagu dhejiyo ee erbium-doped fiber amplifier (EDFA)
Buuqa sare iyo faa'iido yar
