EDFA (Erbium-doped Fiber Amplifier), yakatanga kugadzirwa muna 1987 kuti ishandiswe mukutengeserana, ndiyo amplifier inonyanya kushandiswa muDWDM system inoshandisa fiber yeErbium-doped senzira yekuwedzera masaini kuti iwedzere masaini zvakananga. Inogonesa kuwedzera masaini nekukurumidza kune mawavelengths akawanda, kunyanya mukati memabhendi maviri. Rimwe ndiro Conventional, kana C-band, rinenge kubva pa1525 nm kusvika 1565 nm, uye rimwe ndiro Long, kana L-band, rinenge kubva pa1570 nm kusvika 1610 nm. Panguva iyi, ine mabhendi maviri anowanzo shandiswa, 980 nm uye 1480 nm. Bhandi re980nm rine chikamu chepamusoro chekupinza masaini chinowanzo shandiswa mukushandisa ruzha rushoma, nepo 1480nm bhendi rine chikamu chakaderera asi chakafara chekupinza masaini chinowanzo shandiswa kuma amplifier ane simba rakawanda.
Mufananidzo unotevera unoratidza zvakadzama kuti EDFA amplifier inosimudzira sei zviratidzo. Kana EDFA amplifier ichishanda, inopa pombi laser ine 980 nm kana 1480 nm. Kana pombi laser nemasaini ekupinda zvapfuura nemu coupler, zvichawedzerwa pamusoro peErbium-doped fiber. Kuburikidza nekubatana nemaion edoping, kuwedzera kwechiratidzo kunogona kuwanikwa pakupedzisira. Iyi amplifier ye-optical haingodzikisi chete mutengo asi inovandudza zvakanyanya kushanda kwekuwedzera kwechiratidzo cheoptical. Muchidimbu, EDFA amplifier chiitiko chikuru munhoroondo yefiber optics inogona kuwedzera zvakananga zviratidzo nema wavelengths akawanda pamusoro pefiber imwe chete, pachinzvimbo chekuwedzera kwechiratidzo cheoptical-electrical-optical.
Beijing Rofea Optoelectronics Co, Ltd iri mu "Silicon Valley" yeChina - Beijing Zhongguancun, ikambani yemhando yepamusoro yakatsaurirwa kushandira masangano ekutsvagisa emuno nekunze, masangano ekutsvagisa, mayunivhesiti nevashandi vekutsvagisa kwesainzi vemabhizinesi. Kambani yedu inonyanya kuita tsvakurudzo yakazvimirira nekuvandudza, dhizaini, kugadzira, kutengesa zvigadzirwa zve optoelectronic, uye inopa mhinduro itsva uye masevhisi ehunyanzvi, akagadzirirwa vaongorori vesainzi nemainjiniya emaindasitiri. Mushure memakore ekuvandudza kwakazvimirira, yakagadzira nhevedzano yakapfuma uye yakakwana yezvigadzirwa zve photoelectric, zvinoshandiswa zvakanyanya mumaindasitiri emaguta, mauto, kutakura, simba remagetsi, mari, dzidzo, zvekurapa nedzimwe nzvimbo. Mabhenefiti makuru muindasitiri, akadai sekugadzirisa, mhando, zvirevo, kushanda zvakanaka, sevhisi yakanaka. Uye muna 2016 yakahwina Beijing high-tech enterprise certification, ine zvitupa zvakawanda zve patent, simba rakasimba, zvigadzirwa zvinotengeswa mumisika yemumba nekunze kwenyika, nekushanda kwayo kwakasimba, kwepamusoro-soro kuti iwane rumbidzo kubva kune vashandisi vari kumba nekunze kwenyika!
