EDFA (Erbium-doped Fiber Amplifier), yakatanga kugadzirwa muna 1987 kuti ishandiswe mune zvekutengeserana, ndiyo inonyanya kushandiswa optical amplifier muDWDM system inoshandisa Erbium-doped fiber se optical amplification medium kuti iwedzere zvakananga zviratidzo. Inogonesa kukwidziridzwa kwepakarepo kwemasaini ane akawanda wavelengths, zvakanyanya mukati memabhendi maviri. Imwe ndeyeConventional, kana C-bhendi, ingangoita kubva 1525 nm kusvika 1565 nm, uye imwe yacho Irefu, kana L-bhendi, ingangoita kubva 1570 nm kusvika 1610 nm. Zvichakadaro, ine maviri anowanzo shandiswa kupomba mabhendi, 980 nm uye 1480 nm. Iyo 980nm bhendi ine yakakwira kunyura muchinjiko-chikamu chinowanzo shandiswa mune yakaderera-ruzha application, nepo 1480nm bhendi ine yakaderera asi yakafara kunyura muchinjiko-chikamu chinowanzo shandiswa kune yakakwirira simba amplifiers.
Iyi inotevera nhamba inonyatso ratidza nzira iyo EDFA amplifier inosimudzira masaini. Kana iyo EDFA amplifier ichishanda, inopa pombi laser ine 980 nm kana 1480 nm. Kana pombi yepombi nemasigiro ekuisa achipfuura nemucoupler, anozowedzerwa pamusoro peErbium-doped fiber. Kuburikidza nekudyidzana neiyo doping ions, iyo chiratidzo chekusimudzira chinogona kuwanikwa pakupedzisira. Iyi yese-optical amplifier haingodzikisi zvakanyanya mutengo asi zvakanyanya kunatsiridza mashandiro eiyo optical signal amplifier. Muchidimbu, iyo EDFA amplifier chiitiko chakakosha munhoroondo yefiber optics iyo inogona kusimudza zvakananga masaini neakawanda wavelengths pane imwe fiber, pachinzvimbo cheoptical-electrical-optical signal amplification.
