Sharaxaad: Amplifier fiber-ka Erbium-dopedEDFA Optical Amplifier
Eerbium-doped Optical Fiber amplifier (EDFA, taas oo ah, amplifier-ka ishaarada indhaha ee leh Er3 + doped in xudunta fiber-ka iyada oo loo marayo signalka) waa cod-weyneeye indhaha ugu horreeya oo ay samaysay Jaamacadda Southampton 1985-kii, waana mid ka mid ah hal-abuurrada ugu waaweyn ee isgaarsiinta fiber optic. Fiber-ka Erbium-doped waa nooc ka mid ah fiber-ka oo leh qadar yar oo ah curiyaha dhulka naadirka ah erbium (Er) ions ee fiber quartz, kaas oo ah udub dhexaadkaEerbium-doped fibre amplifier. Laga soo bilaabo dabayaaqadii 1980-aadkii, horumarro waaweyn ayaa laga sameeyay cilmi-baarista erbium-doped amplifiers fiber. Tiknoolajiyada WDM ayaa si weyn u kordhisay awoodda isgaarsiinta fiber optic. Waa cod-weyneeye indhaha ugu badan ee loo isticmaalo isgaarsiinta fiber optic.
Codsiga: Cod-weyneeye fiber optica waa aalad cod-weyneeye oo si toos ah u xoojisa calaamadda indhaha ee nidaamka isgaarsiinta fiber optic. Nidaamka isgaadhsiinta ee la isticmaalayo fiber optic, waa tignoolajiyada si toos ah u xoojisa ishaarka indhaha iyada oo aan calaamadda indhaha u rogin calaamad koronto. Eerbium-doped fiber amplifier (EDFA Optical Amplifier, taas oo ah, amplifier-ga indhaha ee leh erbium ion Er3 + ee xudunta fiber-ka iyada oo loo marayo signalka) waa cod-weyneeye indhaha ugu horreeya oo ay samaysay Jaamacadda Southampton ee Boqortooyada Ingiriiska iyo Jaamacadda Tohoku ee Japan, waa mid ka mid ah hal-abuurrada ugu waaweyn ee isgaarsiinta fiber indhaha. Fiber-ka Erbium-doped waa nooc ka mid ah fiber-ka oo leh qadar yar oo ah curiyaha dhulka naadirka ah ee erbium (Er) ions oo ku jira fiber quartz, kaas oo ah udub dhexaadka Erbium-doped fiber amplifier. Laga soo bilaabo dabayaaqadii 1980-aadkii, horumarro waaweyn ayaa laga sameeyay cilmi-baarista erbium-doped amplifiers fiber.

Erayga la xidhiidha:Amplifier indhaha
Quartz fiber doped leh curiyeyaasha dhulka naadir ah (sida Nd, Er, Pr, Tm, iwm.) waxay sameyn karaan nidaam laser heerar badan ah, oo si toos ah u xoojinaya iftiinka calaamada wax gelinta ee hoos yimaada ficilka iftiinka bamka. Ka dib bixinta jawaab celinta ku habboon, laser fiber ayaa la sameeyay. Dhererka mowjadda shaqaynta ee ND-doped fiber amplifier waa 1060nm iyo 1330nm, laakiin horumarinteeda iyo adeegsigeeda ayaa xaddidan sababtoo ah ka leexashada dekedda ugu habboon ee isgaarsiinta fiber-ka iyo sababo kale. Mawjadaha hawlgalka ee EDFA iyo PDFA waxay ku jiraan khasaaraha ugu hooseeya (1550nm) iyo eber fidinta wavelength (1300nm) daaqada isgaarsiinta fiber indhaha siday u kala horreeyaan, iyo TDFA waxay ka shaqeysaa S-band, taas oo aad ugu habboon codsiyada nidaamka isgaarsiinta fiber indhaha. Gaar ahaan EDFA, horumarka ugu dhakhsaha badan, ayaa ahaa mid la taaban karo.
Iyada oo ku saleysan horumarinta fiber-ka erbium-doped, cod-weyneyaal badan oo fiber-ka cusub ayaa sii wada inay muuqdaan. Tusaale ahaan, laba-band fiber amplifier (DBFA) oo ku salaysan erbium-doped fiber waa cod-weyneeye indho-sarcaad ah, iyo baladh-baandhedku wuxuu dabooli karaa ku dhawaad dhammaan ballaadhiyaha qaybinta hirarka dhererka (WDM). Alaab la mid ah waa ultra-wideband optical amplifier (UWOA), kaas oo leh xajmiga daboolka si uu u kordhiyo ilaa 100 mawjadaha hirarka ee hal fiber.
Codsi wax ku ool ah
Codsiga Eerbium-doped fiber amplifier (EDFA Amplifier) ee nidaamka isgaadhsiinta dhijitaalka ah ee fiber indhaha ee caadiga ah wuxuu badbaadin karaa wax badan oo ku celcelinaya indhaha, iyo fogaanta gudbinta ayaa si weyn loo kordhiyaa, taas oo muhiimad weyn u leh nidaamka jirridda fiilada fogaanta.
Codsiyada ugu muhiimsan waxaa ka mid ah:
1, waxaa loo isticmaali karaa cod-weyneeye fogaan fudud. Fiber optic-ga elektiroonigga ah ee dhaqameedku waxay leeyihiin xaddidaadyo badan. Tusaale ahaan, marka signalka dhijitaalka ah iyo signalka analooga ah la isu rogo midba midka kale, soo-celinta waa in si habboon loo beddelaa; Marka qalabku uu ka beddelo xawaaraha hooseeya una beddelo xawaare sare, ku celcelinta waa in la beddelaa si waafaqsan. Kaliya gudbi mowjadda isku midka ah ee calaamadda iftiinka, qaab-dhismeedku waa mid adag, qaali, iyo wixii la mid ah. Cod-weyneyaasha fiber-ka ee Erbium-doped waxay ka gudbaan cilladahaas, kaliya maaha inay beddelaan isbeddelka habka calaamadaha, laakiin sidoo kale uma baahna in la beddelo marka qalabka la ballaariyo ama loo isticmaalo isku-dhufashada qaybinta hirarka indhaha.
2, waxaa loo isticmaali karaa sidii cod-weyneeye sare oo gudbinta indhaha ah iyo hor-u-qaade-qaadayaasha indhaha. Sida cod-weyneeye sare ee gudbiyaha indhaha, awoodda gudbinta laysarka waa laga kordhin karaa 0db ilaa +10db. Marka loo isticmaalo sidii horudhac ee soo-dhowrka indhaha, dareenkiisa ayaa sidoo kale si weyn loo horumarin karaa. Sidaa darteed, kaliya 1-2 erbium-doped amplifiers ayaa lagu dhejiyay khadka, masaafada gudbinta signalka waxaa lagu kordhin karaa 100-200km.
Intaa waxaa dheer, erbium-doped fiber amplifier (Cod-weyneeye EDFA) si loo xaliyo dhibaatada. Faa'iidooyinka gaarka ah ee Eerbium-doped fibre amplifiers ayaa dunidu aqoonsatay, waxaana aad iyo aad loo isticmaalay. Si kastaba ha ahaatee, Eerbium-doped fibre amplifiers sidoo kale waxay leeyihiin xaddidaadyo. Tusaale ahaan, isgaarsiinta fogfog ma noqon karto kor iyo hoos, xiriirka ganacsi ee saldhigga ayaa aad u adag, ma fududa in la helo cilladaha, bamka iftiinka iftiinka nolosha ma aha mid dheer, iyada oo horumarka joogtada ah ee tiknoolajiyada isgaarsiinta fiber optic, dhibaatooyinkan ayaa la xallin doonaa si lagu qanco.
