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.Meanwhile, 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.
Rofea Optoelectronics muaj cov khoom lag luam ntawm kev lag luam electro-optic modulators, theem modulators, photodetectors, laser lub teeb qhov chaw, dfb lasers, optical amplifiers, EDFAs, SLD laser, QPSK modulation, mem tes laser, lub teeb ntes, sib npaug photodetector, semiconductor laser, laser tsav tsheb fiber ntau coupling, pulsed laser, fiber ntau optic amplifier, kho qhov muag fais fab ntsuas, broadband laser, Tunable laser, optical delayelectro optic modulator, Optical detector, Laser diode tsav tsheb, Fiber amplifier, erbium doped fiber amplifier, laser lub teeb qhov chaw, lub teeb qhov chaw laser.Peb kuj muab ntau yam modulators rau customization, xws li 1 * 4 array theem modulators, ultra-low Vpi, thiab ultra-high extinction ratio modulators, feem ntau siv nyob rau hauv universities thiab institutes.Lawv muaj ib tug wavelength ntau yam ntawm 780 nm rau 2000 nm nrog Electro-optic bandwidths mus txog 40 GHz nrog qis qis qis, qis Vp, siab PER.Haum rau ntau yam kev siv los ntawm analog RF txuas mus rau kev sib txuas lus ceev.
