EDFA Amplifier yog dab tsi?

EDFA (Erbium-doped Fiber Amplifier), thawj zaug tsim tawm xyoo 1987 rau kev siv lag luam, yog lub amplifier optical uas siv ntau tshaj plaws hauv DWDM system uas siv Erbium-doped fiber ua lub nruab nrab amplification optical los txhim kho cov teeb liab ncaj qha. Nws ua rau muaj kev nthuav dav tam sim ntawd rau cov teeb liab nrog ntau lub wavelengths, feem ntau hauv ob txoj kab. Ib qho yog Conventional, lossis C-band, kwv yees li ntawm 1525 nm txog 1565 nm, thiab lwm qhov yog Long, lossis L-band, kwv yees li ntawm 1570 nm txog 1610 nm. Lub caij no, nws muaj ob txoj kab twj siv feem ntau, 980 nm thiab 1480 nm. Txoj kab 980nm muaj qhov nqus dej siab dua feem ntau siv rau hauv daim ntawv thov suab nrov qis, thaum txoj kab 1480nm muaj qhov nqus dej qis dua tab sis dav dua uas feem ntau siv rau cov amplifiers muaj zog dua.

Daim duab hauv qab no qhia meej txog yuav ua li cas EDFA amplifier txhim kho cov teeb liab. Thaum EDFA amplifier ua haujlwm, nws muab lub twj tso kua mis laser nrog 980 nm lossis 1480 nm. Thaum lub twj tso kua mis laser thiab cov teeb liab nkag mus dhau los ntawm lub coupler, lawv yuav raug multiplexed hla Erbium-doped fiber. Los ntawm kev sib cuam tshuam nrog cov doping ions, qhov teeb liab amplification tuaj yeem ua tiav thaum kawg. Lub amplifier tag nrho-optical no tsis yog tsuas yog txo qis tus nqi tab sis txhim kho qhov ua tau zoo rau kev ua kom pom tseeb teeb liab. Hauv ntej, EDFA amplifier yog lub hauv paus tseem ceeb hauv keeb kwm ntawm fiber optics uas tuaj yeem ncaj qha nthuav cov teeb liab nrog ntau lub wavelengths hla ib lub fiber, es tsis txhob optical-electrical-optical teeb liab amplification.

Beijing Rofea Optoelectronics Co, Ltd nyob hauv Suav teb "Silicon Valley" - Beijing Zhongguancun, Yog ib lub tuam txhab high-tech uas mob siab rau kev pabcuam rau cov tsev kawm ntawv tshawb fawb hauv tsev thiab txawv teb chaws, cov tsev kawm ntawv tshawb fawb, cov tsev kawm qib siab thiab cov neeg ua haujlwm tshawb fawb txog kev lag luam. Peb lub tuam txhab feem ntau koom nrog kev tshawb fawb thiab kev txhim kho, tsim qauv, tsim khoom, muag khoom ntawm cov khoom optoelectronic, thiab muab cov kev daws teeb meem tshiab thiab kev tshaj lij, cov kev pabcuam tus kheej rau cov kws tshawb fawb thiab cov kws ua haujlwm hauv kev lag luam. Tom qab ntau xyoo ntawm kev tsim kho tshiab, nws tau tsim cov khoom lag luam photoelectric nplua nuj thiab zoo meej, uas tau siv dav hauv nroog, tub rog, kev thauj mus los, hluav taws xob, nyiaj txiag, kev kawm, kev kho mob thiab lwm yam lag luam. Cov txiaj ntsig zoo hauv kev lag luam, xws li kev hloov kho, ntau yam, cov lus qhia, kev ua haujlwm siab, kev pabcuam zoo heev. Thiab xyoo 2016 yeej daim ntawv pov thawj Beijing high-tech enterprise, muaj ntau daim ntawv pov thawj patent, lub zog muaj zog, cov khoom muag hauv tsev thiab txawv teb chaws, nrog nws cov kev ua tau zoo ruaj khov, zoo dua los yeej kev qhuas ntawm cov neeg siv hauv tsev thiab txawv teb chaws!
