Optical fiber ntau amplifier (OFA) yog ib hom tshiab ntawm tag nrho-optical amplifier siv nyob rau hauv fiber-optic kev sib txuas lus kab los ua kom cov teeb liab.
Raws li nws txoj haujlwm thiab lub luag haujlwm hauv fiber ntau optic kab, nws feem ntau muab faib ua peb hom relay amplification, pre-amplifiua , kabamplifier thiabtxhawb amplifier. Piv nrog rau cov tsoos semiconductor laser amplifier (SOA), OFA tsis tas yuav dhau los ntawm cov txheej txheem nyuaj ntawm kev hloov pauv hluav taws xob, hloov hluav taws xob hluav taws xob thiab teeb liab rov ua dua tshiab, thiab tuaj yeem ncaj qha mus rau amplify lub teeb liab all-optical, nrog zoo "pob tshab", tshwj xeeb tshaj yog. rau qhov ntev-ntev optical kev sib txuas lus relay amplification. Nws tuaj yeem hais tau tias OFA tau tsim lub hauv paus rau kev ua tiav ntawm txhua qhov kev sib txuas lus kho qhov muag.
Optical fiber amplifier thev naus laus zis suav nrog doping cov tub ntxhais fiber ntau ntawm cov khoom siv kho qhov muag nrog cov ntsiab lus tsis tshua muaj hauv ntiaj teb uas tsim lub teeb laser, thiab ua kom pom cov teeb liab dhau los ntawm kev siv hluav taws xob tam sim no los ntawm lub laser. Cov tsoos kho qhov muag fiber ntau kis tau tus mob yog siv optical-hluav taws xob-optical regenerative repeater, hom khoom siv relay no cuam tshuam rau kev ruaj ntseg thiab kev ntseeg siab ntawm lub cev, txhawm rau tshem tawm cov txheej txheem kev hloov pauv saum toj no, ncaj qha rau ntawm txoj kev kho qhov muag ntawm lub teeb liab amplification kis. , nws yog ib qho tsim nyog yuav tsum siv txhua hom kev sib kis ntawm qhov muag rov qab los hloov qhov kev rov ua dua tshiab.
Muaj peb hom fiber ntau optic amplifiers.
(1) SemiconductorOpticalAmplifier (SOA);
(2) doped nrog tsawg lub ntiaj teb cov ntsiab lus (EDFA), Tm, kab lis kev cai Pr, nickel Nd, thiab lwm yam) ntawm optical fiber amplifier, feem ntau pob ntseg-doped optical fiber amplifier (EDFA), Tm-doped optical fiber amplifier (TDFA), praseodymium-doped optical fiber amplifier (PDFA), lwm .;
(3) Non-linear fiber amplifier yog fiber ntau Raman amplifier (FRA, FiberRamanAmplifier).
Nyob rau hauv lub fiber optic nkag network tau tshwm sim F1TH (fiber rau lub tsev), FTTO (fiber mus rau lub chaw ua hauj lwm), FTTB (fiber rau lub tsev), FTTC (fiber mus rau curb), thiab lwm yam., ntawm uas cov loj tshaj plaws daim ntawv thov yog FTTH, qhov nyuaj yog tias cov fiber ntau davhlau ya nyob twg cov ceg ntoo ntau dhau, rau cov tes hauj lwm passive, tom qab ob peb ceg, cov neeg siv tau txais lub zog kho qhov muag qis heev (txog txhua ob npaug, lub zog kho qhov muag poob rau cov tes hauj lwm passive, tom qab ob peb ceg, lub zog kho qhov muag tau txais los ntawm Tus neeg siv tsawg heev (rau txhua ob npaug ntawm cov ceg ntoo, lub zog kho qhov muag txo qis los ntawm 3 dB), ua rau lub davhlau ya nyob twg tsis tuaj yeem ua haujlwm. Nrog rau kev siv fiber ntau optic amplifiers, lub zog tso tawm tau nce, thiab tom qab ob peb ceg, cov neeg siv sab tuaj yeem tseem tau txais ib txwm, ua kom pom tseeb ntawm FTTH ua tau.Qhov tshwm sim thiab kev loj hlob ntawm fiber-optic amplifiers yog li kov yeej qhov teeb meem loj tshaj plaws rau kev sib kis ceev tshaj li kev xauj tsev - qhov kev txwv ntawm kev siv nyiaj siv hluav taws xob kho qhov muag - thiab yog ib qho tseem ceeb tshaj plaws hauv lub h keeb kwm ntawm kev sib txuas lus kho qhov muag.
