Tam sim no muaj ob lub ntsiab ntawm cov qhov hluav taws xob txuas ntxiv: semiconductor optical amplifiers (SOA) thiab (OFA). Lub tshuab hluav taws xob (semiconductor optical amplifier) siv cov hluav taws xob nruab nrog lub zog ua kom cov hluav taws xob ua kom tiav cov khoom siv hluav taws xob kom ua tiav cov teeb meem kho qhov muag, thiab nws cov qauv thiab cov qauv zoo ib yam li cov ntawm cov hluav taws xob semiconductor laser. Ib qho fiber ntau qhov sib txawv yog txawv ntawm qhov ua haujlwm sib txuas ua ke (semiconductor amplifier) hauv qhov nruab nrab nruab nrab (lossis nce nruab nrab) ntawm fiber ntau qhov tshuab txais hluav taws xob yog tshwj xeeb fiber ntau lossis xa cov fiber thiab txuas nrog lub twj tso tawm laser; thaum lub teeb liab hluav taws xob hla lub fiber ntau, lub teeb liab teeb tsa kom nrov dua. Cov kaw lus fiber ntau tau muab faib ntxiv rau Rare Earth Ion Doped Fiber Amplifiers thiab cov kab hluav taws xob tsis ntev ntxiv. Zoo li lub tshuab hluav taws xob semiconductor amplifier, txoj haujlwm ua haujlwm ntawm lub ntiaj teb tsawg kawg doped fiber ntau lub suab nrov tseem tseem txhawb kev tawg; thiab nonlinear fiber ntau lub zog ua kom nrov tau lub teeb liab kho qhov muag los ntawm cov nyhuv tsis zoo ntawm cov fiber. Cov tswv yim ua haujlwm fiber ntau yog erbium doped fiber amplifiers (EDFAs) thiab Raman fiber amplifiers (Raman Fiber Amplifiers).
Cov hluav taws xob fiber ntau tsis tsuas yog ua kom ncaj qha rau cov teeb liab kho qhov muag, tab sis kuj muaj lub sijhawm tiag tiag, siab nce, dav dav, hauv online, suab nrov qis, poob qis txhua qhov kev pom zoo ntxiv, uas yog qhov tseem ceeb uas tsis tseem ceeb hauv kev tsim hluav taws xob tshiab ntawm kev sib txuas lus fiber ntau. ; Lub thev naus laus zis tsis yog tsuas daws cov kev txwv ntawm qhov pom ntawm kev sib txuas ntawm lub network kho qhov muag thiab qhov sib txawv, tab sis tseem ceeb tshaj, nws tsim cov kev faib hluav taws xob sib tshooj hauv 1550nm zaus band, uas yuav pab tau ultra-siab ceev, ultra-loj muaj peev xwm thiab ultra-ntev-nrug wavelength faib multiplexing (WDM). ), Dense Wavelength Division Multiplexing (DWDM), txhua qhov-kis tau tus mob, thiab kis tau tus mob optical soliton tau dhau los ua qhov tseeb, thiab nws yog qhov ua ntu zus hauv keeb kwm ntawm kev sib txuas lus fiber ntau. Hauv kev siv cov tshuab hluav taws xob tam sim no, feem ntau yog cov khoom siv fiber ntau cov khoom siv hluav taws xob (EDFA), cov khoom siv hluav taws xob semiconductor optical amplifiers (SOA) thiab fiber Raman amplifiers (FRA). Ntawm lawv, erbium-doped fiber amplifiers tau dav siv rau lawv qhov kev ua haujlwm ntev. Kev ncua deb, muaj peev xwm, xov tooj hluav taws xob fiber ntau cov kev sib txuas lus, nkag mus rau cov network, fiber ntau pawg CATV network, kev siv tub rog (radar multi-channel data multiplexing, cov ntaub ntawv xa mus, cov kev taw qhia, thiab lwm yam) raws li cov hwj huam amplifiers, relay amplifiers, thiab preamplifiers.
Cov twj tso hluav taws xob feem ntau yog ua kom muaj qhov nruab nrab nce, lub teeb twj tso kua mis, thiab cov lus txuas ntawm cov zis txuas ntxiv. Tam sim no, fiber ntau amplifiers mas suav nrog erbium-doped fiber ntau lub tshuab hluav taws xob, cov khoom siv hluav taws xob semiconductor kho qhov muag thiab fiber ntau Raman amplifiers. Raws li lawv cov ntawv thov hauv cov kab ke hluav taws xob fiber ntau, cov tshuab fiber ntau muaj peb lub hom phiaj: raws li lub zog txuas rau sab hauv lub xa hluav taws xob txhawm rau txhim kho kev sib kis. Lub zog ntawm lub tshuab; tus khoos phis tawm suab ua ntej siv tau ua ntej lub txais khoom txhawm rau txhim kho zoo heev ntawm kev cuam tshuam ntawm cov khoom txais kho qhov muag; cov relay amplifier siv raws li lub suab sib txuas ntxiv hauv cov kab hluav taws xob xa hluav taws xob kom them nyiaj rau qhov kis poob ntawm qhov kho qhov muag thiab kom ntev ntawm qhov sib kis.
