EDFA (Erbium-doped Fiber Amplifier), yomwe idapangidwa koyamba mu 1987 kuti igwiritsidwe ntchito pazamalonda, ndiyo yogwiritsidwa ntchito kwambiri ndi amplifier ya DWDM yomwe imagwiritsa ntchito Erbium-doped fiber monga optical amplification medium kuti apititse patsogolo zizindikiro.Imathandizira kukulitsa nthawi yomweyo kwa ma siginecha okhala ndi mafunde angapo, makamaka mkati mwamagulu awiri.Imodzi ndi Conventional, kapena C-band, pafupifupi kuchokera 1525 nm mpaka 1565 nm, ndipo ina ndi Long, kapena L-band, pafupifupi kuchokera 1570 nm mpaka 1610 nm.Pakadali pano, ili ndi magulu awiri omwe amagwiritsidwa ntchito kwambiri, 980 nm ndi 1480 nm.Gulu la 980nm lili ndi mayamwidwe apamwamba kwambiri omwe nthawi zambiri amagwiritsidwa ntchito popanga phokoso lochepa, pomwe gulu la 1480nm lili ndi gawo lotsika koma lalitali lomwe limagwiritsidwa ntchito ngati zokulitsa mphamvu zapamwamba.
Chithunzi chotsatirachi chikuwonetsa mwatsatanetsatane momwe EDFA amplifier imakwezera ma sign.EDFA amplifier ikagwira ntchito, imapereka laser pump yokhala ndi 980 nm kapena 1480 nm.Laser yapampu ndi zizindikiro zolowera zikadutsa pa coupler, zidzachulukitsidwa pamtundu wa Erbium-doped fiber.Kupyolera mu kuyanjana ndi ma doping ions, kukulitsa chizindikiro kumatha kukwaniritsidwa.Amplifier ya all-optical amplifier iyi sikuti imangochepetsa mtengo koma imathandizira kwambiri kukulitsa kwamawu.Mwachidule, EDFA amplifier ndi chinthu chofunika kwambiri m'mbiri ya fiber optics yomwe imatha kukulitsa mwachindunji zizindikiro ndi mafunde angapo pa fiber imodzi, m'malo mwa optical-electrical-optical signal amplification.
Rofea Optoelectronics imapereka mndandanda wazogulitsa zama electro-optic modulators,phase modulators,photodetectors,laser light sources,dfb lasers,optical amplifiers,EDFAs,SLD laser,QPSK modulation,pulse laser,light detector,photodetector,Semiconductor laser,laser driver ,fiber coupler, pulsed laser, fiber optic amplifier, mita yamagetsi, broadband laser,Tunable laser,optical delayelectro optic modulator,Optical detector,Laser diode driver,Fiber amplifier,erbium doped fiber amplifier,laser light source,Light source laser.Timaperekanso ma modulators ambiri osinthira makonda, monga 1*4 array phase modulators, Ultra-low Vpi, ndi Ultra-high extinction ratio modulators, omwe amagwiritsidwa ntchito m'mayunivesite ndi masukulu. ma electro-optic bandwidth mpaka 40 GHz ndi otsika kuika Loss, low Vp, mkulu PER.Zoyenera kugwiritsa ntchito zosiyanasiyana kuchokera ku maulalo a analogi a RF kupita kumalumikizidwe othamanga kwambiri.
