Yintoni i-EDFA Amplifier?

I-EDFA (i-Erbium-doped Fiber Amplifier), eyaqalwa okokuqala kwi-1987 yokusetyenziswa kwezorhwebo, iyona nto isetyenzisiweyo ye-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, inamaqela amabini okumpompa asetyenziswa 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.

I-Rofea Optoelectronics ibonelela ngomgca wemveliso yeemodyuli ze-electro-optic, iimodyuli zesigaba, ii-photodetectors, imithombo yokukhanya kwelaser, i-dfb lasers, i-optical amplifiers, ii-EDFAs, i-SLD laser, i-QPSK modulation, i-pulse laser, i-detector yokukhanya, i-photodetector elinganayo, i-laser ye-Semiconductor, umqhubi we-laser. ,ifayibha coupler,ipulsed laser,fiber optic amplifier,imitha yamandla okukhanya,ibroadband laser,iTunable laser,optical delayelectro optic modulator,Optical detector,Laser diode driver,Fiber amplifier,erbium doped fiber amplifier,laser light source,Laser source laser.Sikwabonelela ngeemodyuli ezininzi zokwenza ngokwezifiso, ezinje nge-1 * 4 i-array phase modulators, i-Vpi ephantsi kakhulu, kunye ne-ultra-high extinction ratio modulators, esetyenziswa ikakhulu kwiidyunivesithi nakumaziko. i-electro-optic bandwidths ukuya kwi-40 GHz kunye nokufakwa okuphantsi Ilahleko, i-Vp ephantsi, i-PER ephezulu.Ifanelekile kwiindidi ezahlukeneyo zezicelo ezivela kwi-analog RF ikhonkco kunxibelelwano olukhawulezayo.
