EDFA (Erbium-doped Fiber Amplifier), thawj zaug tsim nyob rau hauv 1987 rau kev lag luam siv, yog lub feem ntau deployed optical amplifier nyob rau hauv lub DWDM system uas siv lub Erbium-doped fiber li optical amplification nruab nrab mus ncaj qha mus txhim kho cov teeb liab. Nws enables instantaneous amplification rau cov teeb liab nrog ntau wavelengths, yeej nyob rau hauv ob bands. Ib qho yog Conventional, los yog C-band, kwv yees li ntawm 1525 nm txog 1565 nm, thiab lwm qhov yog Ntev, lossis L-band, kwv yees li ntawm 1570 nm txog 1610 nm. Lub caij no, nws muaj ob feem ntau siv twj tso kua mis, 980 nm thiab 1480 nm. 980nm band muaj qhov nqus siab dua ntu feem ntau yog siv rau hauv daim ntawv thov suab qis, thaum 1480nm band muaj qhov qis dua tab sis dav dua qhov nqus ntu ntu uas feem ntau siv rau lub zog loj dua.
Cov duab hauv qab no qhia ntxaws qhia txog yuav ua li cas EDFA amplifier txhim kho cov teeb liab. Thaum EDFA amplifier ua haujlwm, nws muaj lub twj tso kua mis laser nrog 980 nm lossis 1480 nm. Thaum lub twj tso kua mis laser thiab cov input signals dhau los ntawm lub coupler, lawv yuav tsum multiplexed tshaj Erbium-doped fiber. Los ntawm kev sib cuam tshuam nrog cov doping ions, lub teeb liab amplification tuaj yeem ua tiav thaum kawg. Qhov no all-optical amplifier tsis tsuas yog txo tus nqi tab sis kuj txhim kho qhov ua tau zoo rau kev kho qhov muag teeb liab amplification. Nyob rau hauv luv luv, EDFA amplifier yog ib qho tseem ceeb nyob rau hauv keeb kwm ntawm fiber optics uas muaj peev xwm ncaj qha amplify signals nrog ntau wavelengths tshaj ib fiber, es tsis txhob ntawm optical-hluav taws xob-optical teeb liab amplification.
Beijing Rofea Optoelectronics Co, Ltd nyob rau hauv Tuam Tshoj lub "Silicon Valley" - Beijing Zhongguancun, yog ib tug high-tech enterprise mob siab rau ua hauj lwm nyob rau hauv lub domestic thiab txawv teb chaws tshawb fawb tsev, kev tshawb fawb institutes, universities thiab enterprise scientific kev tshawb fawb neeg ua hauj lwm. kev tshawb fawb thiab kev tsim kho, tsim, tsim, muag khoom ntawm optoelectronic khoom, thiab muab cov kev daws teeb meem tshiab thiab kev tshaj lij, kev pabcuam tus kheej rau Cov kws tshawb fawb tshawb fawb thiab cov kws tshaj lij kev lag luam.Tom qab xyoo ntawm kev ywj pheej innovation, nws tau tsim cov khoom lag luam 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.Great zoo hauv kev lag luam, xws li customization, ntau yam, specifications, high efficiency, zoo heev service.Thiab nyob rau hauv 2016 yeej lub Beijing high-tech enterprise ntawv pov thawj, muaj ntau patent daim ntawv pov thawj, lub zog muaj zog, cov khoom muag muag hauv tsev thiab txawv teb chaws, nrog nws qhov ruaj khov, kev ua tau zoo tshaj los yeej qhuas cov neeg siv khoom hauv tsev thiab txawv teb chaws!
