Yintoni i-EDFA Amplifier

I-EDFA (i-Erbium-doped Fiber Amplifier), eyaqalwa okokuqala kwi-1987 yokusetyenziswa kwezorhwebo, iyona nto isetyenzisiweyo i-optical amplifier kwinkqubo ye-DWDM esebenzisa i-Erbium-doped fiber njenge-optical amplification medium ukuze ikhulise ngokuthe ngqo iimpawu. Ivumela ulwandiso olukhawulezileyo lwemiqondiso enobude bamaza amaninzi, ngokusisiseko ngaphakathi kweebhendi ezimbini. Enye yi-Conventional, okanye i-C-band, malunga ne-1525 nm ukuya kwi-1565 nm, kwaye enye yi-Long, okanye i-L-band, malunga ne-1570 nm ukuya kwi-1610 nm. Okwangoku, ineebhendi zokumpompa ezimbini ezisetyenziswa ngokuqhelekileyo, i-980 nm kunye ne-1480 nm. Ibhendi ye-980nm inomnqamlezo ophezulu wokufunxa odla ngokusetyenziswa kwisicelo sengxolo ephantsi, ngelixa ibhendi ye-1480nm inomnqamlezo osezantsi kodwa obanzi wokufunxa osetyenziswa ngokubanzi kwizikhulisa-mandla eziphezulu.

Eli nani lilandelayo libonisa ngokucacileyo indlela i-EDFA amplifier yokuphucula ngayo iimpawu. Xa i-EDFA amplifier isebenza, inika i-laser yepompo kunye ne-980 nm okanye i-1480 nm. Nje ukuba i-laser yepompo kunye neempawu zegalelo zidlule kwi-coupler, ziya kuphinda-phinda ngaphezulu kwe-Erbium-doped fiber. Ngokusebenzisa i-doping ion, ukukhulisa umqondiso kunokufezekiswa ekugqibeleni. Le amplifier ye-optical all-optical ayinciphisi kakhulu iindleko kuphela kodwa iphucula kakhulu ukusebenza kakuhle kokwandiswa kophawu lokukhanya. Ngamafutshane, i-EDFA amplifier sisiganeko esibalulekileyo kwimbali yefiber optics enokukhulisa ngokuthe ngqo imiqondiso enamaza amaza amaninzi ngaphezulu kwefayibha enye, endaweni yokukhulisa umqondiso we-optical-electrical-optical signal.

IBeijing Rofea Optoelectronics Co, Ltd ibekwe eTshayina “Silicon Valley” – iBeijing Zhongguancun, lishishini lobugcisa obuphezulu elizinikele ekukhonzeni amaziko ophando asekhaya nangaphandle, amaziko ophando, iiyunivesithi kunye nabasebenzi bophando lwezenzululwazi. uphando kunye nophuhliso, uyilo, ukuvelisa, ukuthengiswa kweemveliso ze-optoelectronic, kunye nokubonelela ngezisombululo ezintsha kunye neenkonzo eziqeqeshiweyo, ezenzelwe abaphandi bezenzululwazi kunye neenjineli zezoshishino.Emva kweminyaka yokuqamba okuzimeleyo, iye yaqulunqa uluhlu olucebileyo nolugqibeleleyo lweemveliso ze-photoelectric, ezibanzi ngokubanzi. isetyenziswe kumasipala, emkhosini, kwezothutho, amandla ombane, imali, imfundo, unyango kunye namanye amashishini.Iinzuzo ezinkulu kwishishini, ezifana nokwenza ngokwezifiso, ukuhlukahluka, ukuchazwa, ukusebenza kakuhle, inkonzo egqwesileyo.Kwaye kwi-2016 yaphumelela ishishini eliphezulu laseBeijing. isatifikethi, inezatifikethi ezininzi zelungelo elilodwa lomenzi wechiza, ukomelela olomeleleyo, iimveliso ezithengiswa kwiimarike zasekhaya nakwamanye amazwe, kunye nokusebenza kwayo okuzinzile, okugqwesileyo ukuphumelela ukudunyiswa kwabasebenzisi ekhaya nakwamanye amazwe!
