Yintoni i-EDFA Amplifier

I-EDFA (i-Erbium-doped Fiber Amplifier), eyaqalwa ukwenziwa ngo-1987 ukuze isetyenziswe kwezorhwebo, yeyona amplifier ye-optical esetyenziswa kakhulu kwinkqubo ye-DWDM esebenzisa i-Erbium-doped fiber njengendlela yokukhulisa i-optical ukuze iphucule ngokuthe ngqo imiqondiso. Ivumela ukukhulisa ngokukhawuleza imiqondiso enamaza amaninzi, ngokuyintloko 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 ezimbini zokupompa ezisetyenziswa rhoqo, i-980 nm kunye ne-1480 nm. Ibhendi ye-980nm ine-cross-section ephezulu yokufunxa edla ngokusetyenziswa kwisicelo sengxolo ephantsi, ngelixa ibhendi ye-1480nm ine-cross-section ephantsi kodwa ebanzi yokufunxa edla ngokusetyenziswa kwi-amplifier enamandla aphezulu.

Lo mfanekiso ulandelayo ubonisa ngokweenkcukacha indlela i-amplifier ye-EDFA ephucula ngayo imiqondiso. Xa i-amplifier ye-EDFA isebenza, inikezela nge-laser yepompo ene-980 nm okanye i-1480 nm. Nje ukuba i-laser yepompo kunye nezibonakaliso zokufaka zidlule kwi-coupler, ziya kuphindaphindwa ngaphezulu kwefayibha efakwe i-Erbium. Ngokusebenzisana nee-ion ze-doping, ukwandiswa kwesignali kunokufezekiswa ekugqibeleni. Esi sikhulisi se-all-optical asinciphisi nje kuphela iindleko kodwa siphucula kakhulu ukusebenza kakuhle kokwandiswa kwesignali ye-optical. Ngamafutshane, i-amplifier ye-EDFA sisiganeko esibalulekileyo kwimbali ye-fiber optics enokukhulisa ngokuthe ngqo imiqondiso ene-wavelengths ezininzi phezu kwefayibha enye, endaweni yokwandiswa kwesignali ye-optical-electric-optical.

I-Beijing Rofea Optoelectronics Co, Ltd ekwi "Silicon Valley" yaseTshayina - iBeijing Zhongguancun, lishishini lobuchwepheshe obuphezulu elizinikele ekukhonzeni amaziko ophando asekhaya nakwamanye amazwe, amaziko ophando, iiyunivesithi kunye nabasebenzi bophando lwesayensi yeshishini. Inkampani yethu ibandakanyeka kakhulu kuphando oluzimeleyo nophuhliso, uyilo, imveliso, ukuthengiswa kweemveliso ze-optoelectronic, kwaye ibonelela ngezisombululo ezintsha kunye neenkonzo zobungcali, ezenzelwe wena kubaphandi bezesayensi kunye neenjineli zemizi-mveliso. Emva kweminyaka yokuvelisa izinto ezintsha ngokuzimeleyo, yenze uthotho lweemveliso ze-photoelectric ezityebileyo nezigqibeleleyo, ezisetyenziswa kakhulu kumashishini kamasipala, emkhosini, kwezothutho, kumandla ombane, kwezemali, kwimfundo, kwezonyango nakwamanye amashishini. Iingenelo ezinkulu kushishino, ezinje ngokwenza ngokwezifiso, iintlobo ngeentlobo, iinkcukacha, ukusebenza kakuhle, inkonzo egqwesileyo. Kwaye ngo-2016 yaphumelela isiqinisekiso seshishini lobuchwepheshe obuphezulu saseBeijing, inezatifikethi ezininzi zepatent, amandla aqinileyo, iimveliso ezithengiswa kwiimarike zasekhaya nakwamanye amazwe, kunye nokusebenza kwayo okuzinzileyo, okuphezulu ukuze ifumane udumo lwabasebenzisi ekhaya nakwamanye amazwe!
